Background

The rolling process flow is to perform rolling according to the sequence of passes, such as K6-K5-K4-K3-K2-K1, but sometimes one pass can be omitted, such as K2 passes are omitted, and because the cost is high for modifying a rolling mill set, the rolling mill with K2 passes is not removed, the K2 passes can be subjected to idle running, although the process flow is still K6-K5-K4-K3-K2-K1, but the K2 passes do not generate deformation effect on rolled steel. However, this has the disadvantage that the rolling time cannot be reduced and the idle run of pass K2 is delayed by a certain amount of time.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

The red bar traverse device shown in FIG. 1 is disposed between the first rolling mill 12 and the second rolling mill 13, and passes over the third rolling mill 14.

The old process sequence is first rolling mill 12-third rolling mill 14-third rolling mill 13 (old rolling mill 13' is in position)

In order to use the original rolling train for an old further process sequence, for example for the production of flanged flat steel, the process sequence is still the first rolling mill 12, the third rolling mill 14, the third rolling mill 13 (where the old rolling mill 13' is located), but the third rolling mill 14 is empty. I.e., the red steel does not deform when it passes through the third rolling mill 14. However, the rolling time of the flange slabs is long, and the idle running of the third rolling mill 14 takes a certain rolling time. Because the flange flat steel has small section size and high cooling speed in the rolling process, after rolling, in the process of rolling red steel to manufacture the flange flat steel by a rolling machine, the steel temperature is low, the hardness of the red steel is high, the load of a motor in the rolling process is easy to cause large load, the flange flat steel finished product has scattered springs and the flatness does not reach the standard, and the rejection rate of the flange flat steel is high.

Thus, the new process sequence, first rolling mill 12-third rolling mill 13, passes over third rolling mill 14. The red steel does not pass through the third rolling mill 14. The red steel from the first rolling mill 12 is directly conveyed to the inlet of the second rolling mill 13 by the red steel traversing device of the embodiment, so that the rolling time can be reduced.

To plan the red steel run, the third rolling mill 13 is moved to the left from the position indicated by 13' in fig. 1 to the position indicated by 13. Of course, the second rolling mill 13 may not be moved, for example, the second rolling mill 13 may be rotated in place by 180 degrees, and the red steel 15 may move to the right into the second rolling mill when reaching the discharge end 11.

The specific structure of the red steel transverse moving device is the same. A frame (not shown) is provided having an infeed end 10 and an outfeed end 11. Six driven chain wheels 7 are arranged on the side of the feeding end 10, and six corresponding driving chain wheels 6 are arranged on the side of the discharging end 11. The driving chain wheel 6 and the driven chain wheel 7 are both provided with gear teeth, and a chain 8 is connected between each driving chain wheel 6 and the driven chain wheel 7 through the gear teeth and is driven through the chain 8. The driven chain wheel 7 is a driven wheel, and the driving chain wheel 6 is a driving wheel.

Six driven sprockets 7 are relatively independent. Six driving sprockets 6 are connected in series on the driving shaft 3, and the driving sprockets 6 rotate coaxially with the driving shaft 3. The driving shaft 3 is divided into two supporting shafts, one supporting shaft is longer, the other supporting shaft is shorter, the two supporting shafts are respectively connected to two opposite output ends of the speed reducer 2 through the output coupler 5, the input end of the speed reducer 2 is connected to the output end of the main motor 1 through the input coupler 4, the speed reducer 2 is driven by the main motor 1 and outputs power to the driving shaft 3 after the rotating speed is reduced, the driving shaft 3 drives all driving chain wheels 6 to rotate, a chain 8 rotates when the driving chain wheels 6 rotate, and a driven chain wheel 7 is driven by the chain 8 to rotate.

As shown in fig. 2, a finger 9 is mounted on each chain 8. The pusher dog 9 is used for shifting the red steel 15 to move when the chain 8 rotates. And the main motor 1 makes the pusher dog 9 reciprocate between the feed end 10 and the discharge end 11 by switching the normal rotation and the reverse rotation.

As shown in fig. 1, when the finger 9 is retracted to the feed end 10, the chain 8 receives on it the red steel 15 coming out of the first rolling mill 12. The red steel 15 stays on the striking face 91 side of the striking pin 9 (see fig. 2). The main motor 1 is started, the shifting surface 91 of the shifting claw 9 moves towards and contacts the red steel 15, and then the shifting claw 9 and the chain 8 drive the red steel 15 to move towards the discharging end 11 until the position near the discharging end 11 is reached. The red steel 15 is moved to the left by a human or other machine to make the red steel 15 enter the second rolling mill 13.

As shown in FIG. 2, the toggle surface 91 of the finger 9 is a vertical plane, which is easy to manufacture and not easy to damage the surface of the red steel 15.

As shown in fig. 1, all the driving sprockets 6 are equally spaced and the corresponding driven sprockets 7 are equally spaced, so that the chains 8 are equally spaced, which is advantageous for uniformly supporting the red steel 15.

The driving chain wheel 6 is arranged at the discharging end 11, and compared with the driving chain wheel 6 arranged at the feeding end 10 in other technical schemes, the upper half part of the chain 8, namely the side part in contact with the red steel 15, is easier to be in a stretched straight state, so that the abrasion to the surface of the red steel 15 is reduced.

The chain 8 extends in a direction perpendicular to the discharge direction of the first rolling mill 12 and the chain 8 also extends in a direction perpendicular to the feed direction of the second rolling mill 13, in order to facilitate the transport of the red steel 15 over shorter distances and to further reduce the rolling time.

In this example, the temperature of the rolled steel can be increased by 50 ℃, and the rolling time can be saved by about 30 seconds.

In short, the working principle of the present embodiment is:

after the red steel flows out from the outlet of the first rolling mill 12, the red steel enters the red steel transverse moving device at the feeding end 10 and is overlapped on the chain 8, and after a whole red steel 15 flows out from the first rolling mill 12, the main motor 1 is started. The main motor 1 drives the driving chain wheel 6 to rotate after the linkage action of the input coupling 4, the speed reducer 2, the output coupling 5 and the driving shaft 3 in sequence, and the driving chain wheel 6 drives the chain 8 and the driven chain wheel 7 to rotate through the gear teeth. The chain 8 together with the fingers 9 mounted on the chain 8 move the red steel 15 from the feed end 10 to the discharge end 11 until it reaches the discharge end 11. The red steel 15 is then pushed into the second rolling mill 13 by hand or other machine. The time of red steel passing through the third rolling mill 14 is saved due to the fact that the red steel passes over the third rolling mill 14 in the pass, so that the red steel rolling time is reduced, the cooling time of the red steel 15 during rolling is reduced, the temperature of the red steel 15 after rolling is improved, the hardness of the red steel is not remarkably increased, the red steel is easier to roll in the subsequent process, and the processing quality is higher.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
