Slab width detection system and detection method

Abstract

The invention provides a slab width detection system based on a guide ruler control program set at the entrance of a sizing press. A slab width detection control program is added in the guide ruler control program, the slab width detection control program is respectively connected with a guide ruler alignment control program and a guide ruler position control program, simultaneously, the output end of the slab width detection control program is also connected and communicated with an operating picture via a basic automation network, and the operating picture is connected with an offset alarm system. In the invention, without any investment, via the guide ruler alignment control program and the additionally set slab width detection control program at the entrance of the sizing press, the width offset of the slab is quickly recorded, fed, calculated and displayed, and an alarm is given out in case of out of tolerance, so that the operator can find the problem timely and handle the problem, the width defect of finished products is avoided, waste products are reduced, and both the qualified rate and the rolling yield of band steel are improved.

Description

technical field [0001] The invention belongs to the technical field of industrial electrical automation, and in particular relates to a slab width detection system and a detection method thereof by using a guide rule control computer of a fixed-width press at the front of rough rolling. Background technique [0002] At present, most of the existing domestic rough rolling mills have only one fixed-width press at the front. The entrance of the fixed-width press is equipped with a guide bar. The guide bar at the entrance is controlled by a guide bar control computer. The control program includes guide bar centering control program and guide bar position control program. Using the centering control program and centering function of the inlet guide ruler of the fixed-width press, the accurate centering rolling of the slab is realized. Since there is no equipment for measuring the width of the slab before the roughing mill, when the hot-rolled strip steel production line performs...

AI Technical Summary

Problems solved by technology

Since there is no equipment for measuring the width of the slab before the roughing mill, when the hot-rolled strip steel production line performs equal-width rolling, width defects often occur due to excessive width dimension deviation of raw materials, resulting in defective products or even for waste

If you want to measure the width of the incoming material, you must increase the width measuring equipment

However, the new width measuring equipment not only needs to invest a lot of money, but also cannot be realized due to the limitation of the site.
