Technical Field

Background

In the actual production process, the squeezing roller is used for squeezing acid liquor, rinsing water or alkali liquor on the surface of the strip steel, so that the liquid on the surface of the strip steel is not brought into the subsequent working procedure. Meanwhile, in the squeezing process, other defects such as scratches are not generated, so that the rubber on the surfaces of the squeezing rollers has certain wear resistance and elasticity, and in the continuous production process, the upper squeezing roller and the lower squeezing roller press the strip steel in the middle under the action of certain pressure and rotate along with the running of the strip steel. Due to improper adjustment of the pressing amount of the drying roller, along with the operation of different specifications of strip steel, the abrasion loss of the drying roller can be rapidly increased, the condition that the surface of the drying roller is degummed or the surface groove of the drying roller is deepened and is not enough to completely dry the strip steel occurs, so that the liquid on the surface of the strip steel is brought into the next process to influence the product quality, and at the moment, the production can be met only by replacing a new roller with a new roller after the drying roller is placed off.

At present, the traditional adjustment operation method of the drying roller is to adjust the current pressing amount of the drying roller to the state before the drying roller is replaced after the drying roller is installed, and then the equipment can be put into production. However, although the operation mode can meet the basic operation and adjustment requirements of the drying roll at the present stage, the pressing amount of the drying roll cannot be guaranteed to be completely matched with the steel strip, especially, the operation is basically performed by depending on the experience of an operator during actual operation, the installation and adjustment precision of the drying roll cannot be guaranteed, the abrasion degree of the drying roll cannot be accurately mastered and planned after the subsequent equipment runs for a long time, and various adverse effects are caused to the stable running and production operation continuity of the related equipment.

Therefore, how to improve the installation and adjustment accuracy of the drying roller and optimize the operation effect of the equipment is an important technical problem which needs to be solved by the technical personnel in the field at present.

In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a flowchart illustrating an operation method of a wringing roller apparatus according to an embodiment of the present invention.

In one embodiment of the present invention, a method of operating a wringer roller apparatus is provided that includes:

step 101: positioning and marking;

after a new wringing roller is replaced on the equipment, the levelness of the upper wringing roller and the lower wringing roller is measured, so that the wringing rollers are kept in a horizontal state, the axial direction of the wringing rollers is perpendicular to the conveying direction of the strip steel, meanwhile, the rolling reduction of the two wringing rollers is adjusted to the extent that the roller surfaces of the two wringing rollers can be simultaneously contacted with the strip steel when in a rolling down state and no pressure is applied, at the moment, a reference mark corresponding to the current wringing roller assembly position is arranged on the wringing roller equipment, so that the reference mark can be referred as the initial assembly position and the rolling reduction reference of the newly replaced wringing roller when the wringing rollers are replaced later.

Furthermore, the reference mark is positioned on an end bearing of the wringing roller equipment corresponding to each wringing roller or positioned on a frame of the wringing roller equipment. In consideration of the operation difficulty under the actual working condition and the operation requirement under the general condition, the reference mark is preferably arranged on the end bearing corresponding to each drying roller on the drying roller equipment.

In addition, the reference mark may be marked by a marker pen, or may be a machined structural mark, and in principle, the reference mark may be any mark that can meet the practical application requirements of the wringing roller equipment.

More specifically, in the dynamic adjustment of the steps, the strip steel processing amount is continuously monitored, the wringing roller equipment is temporarily stopped after the wringing roller equipment continuously processes 10000 tons of strip steel, and then the pressing amount of the wringing roller is downwards adjusted by 2mm, so that the roller surface of the wringing roller is fully fitted and adapted with the strip steel.

It should be noted that the staged continuous processing amount of 10000 tons of strip steel corresponding to each temporary shutdown of the drying roll equipment is only a conventional parameter under a general working condition, and in practical application, according to different specific production tasks and working conditions, a worker can flexibly adjust specific parameters of the staged strip steel processing amount, and in principle, the drying roll equipment can be stably operated as long as the smooth dynamic adjustment step can be ensured.

Further, in the step of stopping and replacing the roll, the limit size is 3mm, namely, when the depth of a groove formed by the extrusion abrasion of the roll surface by the edge of the strip steel at the position of the end edge of the wringing roll reaches 3mm, the wringing roll equipment is stopped, and the current wringing roll is dismounted. Of course, in practical application, the working personnel can flexibly adjust the parameters of the limit size according to the importance degree of different stations and the specific requirements on the degree of influence of the surface quality, and in principle, the stable operation of the wringing roller equipment can be met.

In addition, it should be specially noted that, in the implementation process of the above steps, if the wringing roller equipment is stopped, the wringing rollers are opened, so that the wringing rollers are separated from the alignment and compression state, and the elasticity of the rubber layer on the surface of the wringing rollers is recovered. Therefore, the downtime of the wringing roller equipment can be fully utilized, the rubber layer on the roller surface of the wringing roller can be fully rebounded under the non-working state of the wringing roller equipment, the service life of the wringing roller can be properly prolonged, the replacement frequency of the wringing roller is reduced, and the running and use cost of the wringing roller equipment can be correspondingly reduced.
