Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In an embodiment of the application, a crooked rollgang that rises, including the straight line horizontal segment 1 and the crooked segmental ascent 3 that connect gradually, the crooked segmental ascent 3 all is less than or equal to 8 with the contained angle of horizontal plane, the straight line horizontal segment 1 with the crooked segmental ascent 3 is formed by 6 permutation and combination of rollgang units, and per two adjacent rollgang units 6 pass through baffle fixed bolster and connect.

Wherein, roller table unit 6 includes:

the H-shaped bracket 61 is arranged on the ground;

the steel platform 62 is arranged on the H-shaped bracket 61;

the base 63 is arranged on the steel platform 62;

the roller 64 is erected on the base 63 and is rotatably connected with the base 63;

and the baffle plates 66 are arranged at two ends of the roller 64, and the bottoms of the baffle plates 66 are fixed on the base 63 through baffle plate fixing brackets.

The long-strip-shaped steel billet enters the linear horizontal section 1 after being discharged from the previous process, then passes through the bent ascending section 3, the steel billet is driven to ascend while the conveying direction of the steel billet is adjusted by the bent ascending section 3, the steel billet deviates from the direction of the linear horizontal section 1 and is aligned with the inlet of the next process, the steel billet can quickly enter the next process with different height and horizontal position by the conveying of the bent ascending roller way, the residence time of the steel billet in the process gap is reduced, the temperature of the steel billet is effectively maintained, and the temperature of the 1000 ℃ steel billet output from a continuous casting machine of a steel mill is reduced by not more than 50 ℃ before being conveyed to the next process.

The included angles between the bent ascending sections 3 and the horizontal plane are all less than or equal to 8 degrees, so that the component force of the weight of the steel billet on the inclined plane of the roller way is less than the friction force between the steel billet and the roller way, and the rotating rollers 64 can drive the steel billet to move along the roller way.

As an embodiment of the present application, the curved rising section 3 includes an inner arc rising section 31 and an outer arc rising section 32, both the inner arc rising section 31 and the outer arc rising section 32 are arc-shaped, and the inner arc rising section 31 is tangent to the outer arc rising section 32.

The billet firstly passes through the inner arc ascending section 31 to enable the billet to ascend and simultaneously deviate the transportation direction, and then passes through the outer arc ascending section 32 to deviate the transportation direction after deviation back again, so that the transportation direction of the billet in the second straight ascending section 4 and the first straight ascending section 2 is parallel but the center of the billet deviates, and the billet is smoothly butted with the entrance of the next procedure. The tangent inner arc ascending section 31 and the tangent outer arc ascending section 32 also enable the transition of the billet at the joint to be smooth and not easy to clamp.

As an embodiment of the present application, the arc angle of the inner arc ascending section 31 and the outer arc ascending section 32 is less than 21 ° v

Through calculation and experiments, when the arc angle is larger than or equal to 21 degrees, the bending limit of the high-temperature steel billet can be exceeded, so that the steel billet is clamped at the bent position, the transportation efficiency is influenced, even the steel billet is stopped at the bent position and cannot move along with a roller way, the arc angles of the inner arc ascending section 31 and the outer arc ascending section 32 are smaller than 21 degrees, the steel billet can be rapidly transported without clamping, the retention time of the steel billet in a process gap is reduced, and the temperature of the steel billet is effectively maintained.

As an embodiment of the present application, a first straight-line rising section 2 is further disposed between the straight-line horizontal section 1 and the curved rising section 3, and a second straight-line rising section 4 is further connected to one end of the curved rising section 3, which is far away from the first straight-line rising section 2.

The first straight line ascending section 2 only ascends without bending, a certain included angle is formed between the first straight line ascending section and the straight line horizontal section 1, a certain included angle is also formed between the first straight line ascending section and the bent ascending section 3, a transition effect is achieved between the straight line horizontal section 1 and the bent ascending section 3, the steel billet is enabled to bend smoothly at the junction of the straight line horizontal section 1 and the bent ascending section 3, the steel billet is prevented from being clamped at the junction of the straight line horizontal section 1 and the bent ascending section 3, and the steel billet can be transported smoothly.

As an embodiment of the present application, the first straight rising section 2 is tangent to the curved rising section 3, and the curved rising section 3 is tangent to the second straight rising section 4. The transition of the steel billet at the connecting part of the first straight ascending section 2, the bent ascending section 3 and the second straight ascending section 4 is smooth and not easy to clamp.

As an embodiment of the present application, the transport speed of the first straight ascending section 2, the curved ascending section 3 and the second straight ascending section 4 is greater than that of the straight horizontal section 1, and the power mechanism 65 of the roller table unit 6 constituting the straight horizontal section 1 is a variable frequency power mechanism 65.

Since the outer wall of the continuous casting machine of the steel mill in the previous process is opaque and the condition of the billet cannot be known, the billet needs to be slowly conveyed out of the continuous casting machine of the steel mill, the condition of the billet is observed on the straight horizontal section 1, if the quality of the billet does not reach the standard, the reversing frequency conversion power mechanism 65 returns the billet to the continuous casting machine of the steel mill again, but in order to reduce the exposure time of the billet between the previous process and the next process, the conveying speed needs to be increased afterwards, so that the conveying speed of the first straight ascending section 2, the bent ascending section 3 and the second straight ascending section 4 is larger than that of the straight horizontal section 1, and the conveying speed of the billet can be increased while the straight horizontal section 1 for observing the billet is remained.

As an embodiment of the present application, the widths of the straight horizontal section 1 and the first straight ascending section 2 are less than or equal to three-fourths of the widths of the curved ascending section 3 and the second straight ascending section 4, wherein the width of the straight horizontal section 1 is 600mm, and the widths of the curved ascending section 3 and the second straight ascending section 4 are 800 mm.

On one hand, because the billet needs to undergo a bending process when passing through the bent rising section 3, the widths of the bent rising section 3 and the second straight rising section 4 are set to be wider, so that the bending angle of the billet can be smaller, the friction force between the billet and the baffle 66 is reduced, the billet is prevented from being clamped at a corner in the conveying process, and the billet can be smoothly conveyed at a high speed.

On the other hand, since the high-temperature slab discharged from the continuous casting machine of the steel mill may have a bend, the bent slab can be extruded and collected through the narrower straight-rising section to be straightened to some extent so as to be smoothly transferred to the bent-rising section 3.

As an embodiment of the present application, the top surfaces of the straight horizontal segment 1, the first straight ascending segment 2, the curved ascending segment 3 and the second straight ascending segment 4 are all provided with heat insulation covers.

The heat loss of the steel billet can be further prevented by arranging the heat preservation cover.

As an embodiment of the present application, a top surface of the second straight-line rising section 4 is provided with a converging baffle 5.

The billet is slightly bent after passing through the bent ascending section 3, and the shape of the billet can be restrained through the converging baffle 5 to be restored to be a linear shape.

The billet passes through the straight line horizontal segment 1, the first straight line ascending segment 2, the inner arc ascending segment 31, the outer arc ascending segment 32 and the second straight ascending segment 4 in sequence after being discharged from the continuous casting machine of the steel plant, the billet undergoes ascending, bending and straightening, the position of the billet is lifted from the lower part to the higher part, the horizontal position of the billet is deviated but not changed, high-speed transportation is realized through a roller way, the front and the rear processes are connected, the residence time of the billet in the process gap is reduced, the temperature of the billet is effectively maintained, the energy is saved, the follow-up billet reheating is avoided, the billet oxidation burning loss caused by billet secondary heating is reduced, the heating gas consumption is reduced, the SO is reduced, the energy consumption is reduced, the subsequent reheating of the billet is avoided, the secondary heating of the billet is reduced, and the secondary heating is realized₂And NOx, dust and other pollutants are discharged, and the consumption of cooling water, compressed air and grease of the heating furnace in the original production mode is saved. Meanwhile, after a secondary heating process is omitted, production operators of the heating process are reduced, management and operation processes are simplified, intrinsic safety production is realized, meanwhile, the method is also a green environment-friendly product which is deeply applied in the steel industry, and a foundation is laid for creating a green factory.
