Embodiment Construction

[0053] In order to better understand the above technical solutions, the technical solutions of the embodiments of the present specification will be described in detail below through the accompanying drawings and specific embodiments. The detailed description is not intended to limit the technical solutions of the present specification, and the embodiments of the present specification and the technical features in the embodiments may be combined with each other under the condition of no conflict.

[0054] This embodiment provides a method for improving the quality of high-strength steel trimming, such as figure 1 As shown, the method mainly includes the following steps:

[0055] S110, before cutting the steel edge of the target strip, control the disc shear to cut a preset amount of mild steel in advance; the mild steel is a steel with a yield strength less than 200 MPa;

[0056] Because the target strip steel is high-strength steel, the high-strength steel itself has high str...

Abstract

According to the method, the device, the medium and the equipment for improving the trimming quality of the high-strength steel, after a preset number of soft steel is sheared through a circle shear, due to the fact that the yield strength of the soft steel is smaller than 200 MPa, the uniformity of the temperature of a shear blade can be ensured, local hard points or local soft points are prevented from occurring in the shear blade, and the trimming quality of the high-strength steel is improved. Cracks on the edge part of the subsequently sheared strip steel are avoided; then the corresponding shear blade lateral gap and shear blade coincidence amount are determined based on the actual thickness and the product type of the target strip steel, the influence of the product characteristics of the target strip steel on the shearing parameters of the circle shear is fully considered, then the shearing precision of the circle shear can be ensured, and the trimming quality of high-strength series continuous annealing products and galvanized products is ensured.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a method, device, medium and equipment for improving the quality of high-strength steel trimming. Background technique [0002] After the cold-rolled strip has been continuously withdrawn, it is necessary to use disc shears to trim the edge of the strip. One is to precisely control the width of the strip according to the order requirements, and the other is to remove the edge defects of the strip. Therefore, the parameter setting of the disc shearing equipment and its control accuracy will have a great impact on the quality of strip trimming and the stability of equipment operation. [0003] Especially for high-strength series products, due to the high strength of high-strength steel itself and the difficulty in controlling the shape of the plate, in the related art, due to improper control of the parameters of the disc shearing edge, the shearing edge is damaged and the st...
