Problems solved by technology

Therefore, most of the products produced by widening blanks can only be disposed of according to the agreed products, causing a lot of waste to the enterprise
[0003] It can be seen that the width of the widening billet in the current hot rolling process is uneven, resulting in serious waste

[0037] See figure 1 , figure 1 A flow chart of a method for controlling the width of a hot-rolled widening billet provided by the first embodiment of the present invention is shown. The steps that described method comprises are as follows:

[0038] Step S10: On the width-adjusting billet before entering the side press, determine a plurality of head measurement points and a plurality of tail measurement points.

[0039] In step S10 , since the side press needs to be controlled, it is necessary to measure the width of the widening billet before entering the side press. Multiple head measurement points should be close to the head position of the widening blank, and multiple tail measurement points should be close to the tail position of the widening blank. In order to avoid the influence of mutual interference of short-stroke control, the head and tail of the widening billet can be removed before determining the measurement point, that is, the specific execution of step S10 is...

Abstract

The invention discloses a method and device for controlling the width of a hot-rolled width-adjusting blank, wherein the method comprises the steps: determining a plurality of head measurement points and a plurality of tail measurement points on the width-adjusting blank before the width-adjusting blank enters a side press; based on the plurality of head measuring points and the plurality of tail measuring points, acquiring the slab length, the head width reduction amount and the tail width reduction amount; based on the slab length, the head width reduction amount and the tail width reduction amount, acquiring a width reduction amount adjusting coefficient; and on the basis of the width reduction amount adjusting coefficient, controlling the side press under variable pressure. According to the invention, width-adjusting blanks with more uniform head and tail widths can be obtained, so that production waste is avoided.

Description

technical field [0001] The invention relates to the technical field of steelmaking, in particular to a method and device for controlling the width of a hot-rolled widening billet. Background technique [0002] In order to meet the product width requirements of the hot rolling line and the limitation of the width reduction capacity, the continuous casting process generally designs multiple slab width billets, and the width adjustment billets will appear when switching between different slab widths. The width of the head and tail of the billet is uneven, and the width difference between the head and the tail is generally 20-150mm. For the width-adjusted slab, the width of the hot-rolled slab is generally controlled according to the normal slab, resulting in a wedge-shaped width of the finished product. Therefore, most of the products produced by widening billets can only be disposed of according to the agreed products, causing a lot of waste to the enterprise. [0003] It ca...
