Strip steel control plate type operation method

Abstract

The invention discloses a strip steel control plate type operation method and relates to the technical field of strip steel manufacturing. The strip steel control plate type operation method comprises the following steps of: step 1, strip steel annealing: putting strip steel in equipment for annealing heat treatment, and then putting the strip steel on a guide rail of a rack; step 2, intermediate blank plate control: operating a control panel to adjust rough rolling parameters and conducting press-rolling on an intermediate blank plate by observing the conditions of a guide plate monitor on the inlet side of a hot coil box, a coil shape of the hot coil box, an optimized shearing curve graph, a deviation change of rolling force of finish rolling F1-F2 and a wedge shape change of a straightness instrument; and step 3, load distribution: operating the control panel to adjust loads of racks 4, 5 and 6 to be as small as possible. According to the strip steel control plate type operation method, judgment is conducted by observing the conditions of the guide plate monitor on the inlet side of the hot coil box, the coil shape of the hot coil box, the optimized shearing curve graph, the rolling force deviation change of finish rolling F1-F2 and the wedge shape change of the straightness instrument, rough rolling is adjusted in time, the situation that the strip shape is good when a thin specification is rolled is ensured, and then the quality of the produced strip steel is improved.

Description

technical field [0001] The invention relates to the technical field of strip steel production, in particular to an operation method for strip steel control plate shape. Background technique [0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, is within 1300mm in width, and the length is slightly different according to the size of each roll. [0003] In the production process of strip steel, due to the rough rolling incoming material plate shape or rolling instability, etc., resulting in non-technical flatness, there are waves and waves on the plate surface after leveling. In addition, when the intermediate billet is wedge-shaped and side-bent (C Bending, S-bending) is difficult to control the finishing rolling, especially S-bending, the tail inclination of the finishing head...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an operation method for controlling the shape of the strip in order to solve the problems in the prior art that there are wave breaking and floating phenomena after the surface of the strip is flattened, and the finishing rolling is difficult to control and the tail is inclined.
