Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments of the present invention belong to the scope of protection of the embodiments of the present invention.

The embodiment of the invention provides a method and a system for controlling the finish rolling speed of strip steel, and aims to solve the technical problem of low production efficiency of finish rolling of the strip steel in the prior art by reasonably adjusting finish rolling operation.

In order to solve the technical problems, the embodiment of the invention has the following general idea:

a method for controlling the finish rolling speed of strip steel, as shown in fig. 1, comprising:

step S1, acquiring a first acceleration, a coiling and threading speed, a second acceleration, a highest rolling speed, a first deceleration and a steel throwing speed corresponding to a preset target strip steel;

step S2, after the threading of the target strip steel is completed and the finish rolling outlet pyrometer is switched on, the rolling speed of the target strip steel is increased based on the first acceleration with the aim that the rolling speed reaches the coiling threading speed or the coiling steel biting signal is switched on;

step S3, after the coiling steel biting signal is switched on, the rolling speed is increased again based on the second acceleration with the aim that the rolling speed reaches the highest rolling speed or the flying shear tail cutting signal is switched on;

and step S4, after the flying shear tail cutting signal is switched on, the rolling speed is reduced based on the first deceleration with the aim that the rolling speed reaches the steel throwing speed or the steel throwing at the tail part of the target strip steel.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

Generally, a strip passes through a flying shear from a rough rolling outlet to a finish rolling area, the finish rolling area is an area between a first stand and a last stand of a finish rolling mill, the finish rolling mill finishes the strip, then the rolled strip is polished to enable the strip to pass through the whole laminar cooling device to reach a coiling machine, and the strip is coiled by the coiling machine. The target strip described in this example is typically a tin plate.

In step S2, the finish rolling exit pyrometer is turned on and the strip finish rolling exit temperature value is detected, and compared with the set finish rolling exit temperature target value, and the measured value of the strip exit temperature at the finish rolling is infinitely brought close to the set strip finish rolling exit temperature target value by adjusting the amount of cooling water and the acceleration of the strip between the finish rolling stands. Experiments show that for the tin plate, when the temperature value of the strip steel finish rolling outlet of the tin plate is accurately controlled to be close to the target value, good performance can not be obtained all the time, however, when the finish rolling model controls the actually measured temperature value of the strip steel finish rolling outlet to be within a certain range higher than the target value, better product performance can be obtained. Therefore, the temperature value of the finish rolling outlet is controlled according to the upper limit of the standard control range, and the product performance can be guaranteed not to be influenced. In the embodiment, the first acceleration is started after the finish rolling outlet pyrometer is switched on for 1s, so that the control process of the strip steel finish rolling outlet temperature can be ensured to be established.

Finishing threading of the target strip steel, namely, enabling the head of the target strip steel to leave the last frame of the finishing mill; the coiling threading speed is the maximum speed allowed by the strip threading and the coiling machine to start to coil the strip, and the coiling biting signal is switched on to represent that the head of the target strip starts to coil. After the first acceleration of the rolling speed is carried out based on the first acceleration, the rolling speed can reach the coiling threading speed before the coiling steel biting signal is switched on, or the rolling speed can not reach the coiling threading speed when the coiling steel biting signal is switched on. In this embodiment, before the steel coiling biting signal is turned on, if the rolling speed does not reach the coiling and threading speed, the rolling speed is increased until the steel coiling biting signal is turned on, and if the rolling speed reaches the coiling and threading speed, the rolling speed is kept at the coiling and threading speed until the steel coiling biting signal is turned on. Thus, the step S2 can increase the rolling speed of the target strip as much as possible when the target strip head goes from the last stand of the finishing mill to the coiler, to reduce the time consumed by the target strip head from the last stand of the finishing mill to the coiler, i.e., to reduce the pure rolling time, thereby improving the production efficiency.

In step S3, the maximum rolling speed is the maximum rolling speed allowed by the finishing mill, and the flying shear tail-cutting signal is turned on to represent the target strip steel is subjected to tail-cutting. In the embodiment, the rolling speed of the target strip steel is accelerated for the second time based on the second acceleration after the coiling steel biting signal is switched on for 1s, and the coiling machine starts to coil the target strip steel after the coiling steel biting signal is switched on. After the second acceleration is started, the rolling speed can reach the highest rolling speed before the flying shear tail-cutting signal is switched on, or the rolling speed can not reach the highest rolling speed when the flying shear tail-cutting signal is switched on. In the embodiment, before the flying shear tail-cutting signal is switched on, if the rolling speed does not reach the highest rolling speed, the rolling speed is increased until the flying shear tail-cutting signal is switched on, and if the rolling speed reaches the highest rolling speed, the rolling speed is kept at the highest rolling speed until the flying shear tail-cutting signal is switched on. In this way, in step S3, the rolling speed of the target strip can be increased as much as possible after the start of coiling the head of the target strip and before the end of the target strip is cut by the flying shears, so as to reduce the time consumed from the start of coiling the head of the target strip to the end of the target strip, i.e., the pure rolling time, thereby improving the production efficiency.

In step S4, the steel throwing speed is the maximum speed allowed by the steel throwing at the tail of the target strip steel. In the embodiment, the rolling speed is reduced after the flying shear tail cutting signal is switched on for 0.5 s. After the target strip steel is subjected to tail cutting, the speed of the tail of the target strip steel after passing through the last rack of the finishing mill is not higher than the steel throwing speed, namely the rolling speed of the tail steel throwing is not higher than the steel throwing speed, so that the rolling speed is reduced as far as possible to meet the requirement.

Thus, the embodiment increases the rolling speed of the target strip as much as possible when the head of the target strip goes from the last stand of the finishing mill to the coiler, so as to reduce the time consumed when the head of the target strip goes from the last stand of the finishing mill to the coiler; after the head of the target strip steel starts to be coiled and before the tail of the target strip steel is cut by flying shears, the rolling speed of the target strip steel is increased as much as possible so as to reduce the time consumed by the head of the target strip steel from being coiled to the tail of the flying shears; after the flying shear cuts the tail, the rolling speed of the target strip steel is reduced to the steel throwing speed as far as possible before the tail of the target strip steel leaves the finishing mill, and the three stages reduce the pure rolling time from the time that the head of the target strip steel leaves the finishing mill to the time that the tail of the target strip steel leaves the finishing mill, so that the production efficiency is improved. As shown in fig. 2, which is a comparison table of the effects before and after the method for controlling the strip steel finish rolling speed according to the embodiment, it can be seen that the pure rolling time and the rolling rhythm of the strip steel are significantly reduced and the rolling yield per hour is significantly improved after the method for controlling the strip steel finish rolling speed according to the embodiment is applied.

In step S1, each parameter needs to be set in advance, but different parameters need to be set for different specifications of strip steel. For this purpose, step S1 specifically includes: dividing the strip steel into different specification groups according to the product specification, and setting corresponding rolling parameters for each specification group; and determining the specification group to which the target strip steel belongs and setting the specification group as a target specification group, and acquiring a first acceleration, a coiling strip-threading speed, a second acceleration, a highest rolling speed, a first deceleration and a steel-throwing speed in the rolling parameters corresponding to the target specification group.

The method of the embodiment is applied to a high-speed rolling mode, before a specification group is set, for each strip steel to be rolled, the information outline of the strip steel needs to be obtained, whether the high-speed rolling mode is used for the strip steel is judged according to the components of the strip steel, and the specification group is set after the high-speed rolling mode is determined to be used. Wherein the product specification may include one or more of the width, thickness, weight, and steel grade of the strip. The results of dividing all the strip steels into different gauge groups are shown in fig. 3, and the results of setting the corresponding rolling parameters for each gauge group are shown in fig. 4.

In step S4, since the first deceleration is preset, if the first deceleration is set too small, the rolling speed may not be reduced to the steel-throwing speed when the tail of the target strip steel is thrown, which may affect the steel-throwing process. For this reason, in this embodiment, after the step S4, the method for controlling the finish rolling speed of the strip further includes: if the rolling speed does not reach the steel throwing speed when the tail of the target strip steel is thrown, calculating a second deceleration according to the highest rolling speed, and replacing the first deceleration with the second deceleration so as to enable the rolling speed to be not more than the steel throwing speed when the tail of the next target strip steel is thrown. Wherein, calculating the second deceleration according to the highest rolling speed comprises:a is the second deceleration, V2 is the highest rolling speed, V1 is the throwing speed, and X is the distance from the flying shear to the last stand of the finishing mill. Of course, when the next target strip steel is finish rolled, if the rolling speed does not reach the highest rolling speed when the flying shear tail cutting signal is switched on, the rolling speed is smaller than the steel throwing speed when the tail of the next target strip steel is thrown, which is acceptable.

This embodiment still provides a belted steel finish rolling speed control system, includes:

the parameter acquisition module is used for acquiring a first acceleration, a coiling and threading speed, a second acceleration, a highest rolling speed, a first deceleration and a steel throwing speed which correspond to preset target strip steel;

the speed control module is used for increasing the rolling speed of the target strip steel based on the first acceleration with the aim that the rolling speed reaches the coiling threading speed or the coiling steel biting signal is switched on after the target strip steel is threaded and the finish rolling outlet pyrometer is switched on;

the speed control module is also used for increasing the rolling speed again based on a second acceleration with the aim that the rolling speed reaches the highest rolling speed or a flying shear tail cutting signal is switched on after the coiling steel biting signal is switched on;

the speed control module is also used for reducing the rolling speed based on the first deceleration with the aim that the rolling speed reaches the steel throwing speed or the steel throwing of the tail part of the target strip steel after the flying shear tail cutting signal is switched on.

The strip steel finish rolling speed control system of the embodiment improves the rolling speed of the target strip steel as much as possible when the head of the target strip steel is from the last stand of the finish rolling mill to the coiler so as to reduce the time consumed when the head of the target strip steel is from the last stand of the finish rolling mill to the coiler; after the head of the target strip steel starts to be coiled and before the tail of the target strip steel is cut by flying shears, the rolling speed of the target strip steel is increased as much as possible so as to reduce the time consumed by the head of the target strip steel from being coiled to the tail of the flying shears; after the flying shear cuts the tail, the rolling speed of the target strip steel is reduced to the steel throwing speed as far as possible before the tail of the target strip steel leaves the finishing mill, and the three stages reduce the pure rolling time from the time that the head of the target strip steel leaves the finishing mill to the time that the tail of the target strip steel leaves the finishing mill, so that the production efficiency is improved.

Further, the parameter obtaining module comprises: the grouping setting submodule is used for dividing the strip steel into different specification groups according to the product specification and setting corresponding rolling parameters for each specification group; and the parameter acquisition submodule is used for determining the specification group to which the target strip steel belongs, setting the specification group as a target specification group, and acquiring a first acceleration, a coiling strip-threading speed, a second acceleration, a highest rolling speed, a first deceleration and a steel throwing speed in the rolling parameters corresponding to the target specification group. Wherein the product specification may include one or more of the width, thickness, weight, and steel grade of the strip. Thus, different parameters can be set for the strip steels with different specifications.

Further, the strip steel finish rolling speed control system further comprises: and the deceleration setting module is used for calculating a second deceleration according to the highest rolling speed when the rolling speed does not reach the steel throwing speed during the steel throwing of the tail part of the target strip steel, and replacing the first deceleration with the second deceleration so as to enable the rolling speed to be not more than the steel throwing speed during the steel throwing of the tail part of the next target strip steel. Therefore, when the rolling speed cannot be reduced to the steel throwing speed when the tail of the current target strip steel is thrown, the rolling speed is not higher than the steel throwing speed when the tail of the next target strip steel is thrown, and the influence on the steel throwing process is avoided.

Based on the same inventive concept as the strip finish rolling speed control method, the embodiment further provides an electronic device, which comprises a memory, a processor and a computer program stored in the memory and capable of running on the processor, wherein the processor executes the program to realize the steps of any one of the strip finish rolling speed control methods.
