Production process of hot-rolled steel plate

Abstract

The invention relates to a production process of a hot-rolled steel plate. The production process comprises a bottom plate, a lifting device, a bearing bracket and a placement frame; a conveying device is mounted on the right side of the upper end of the bottom plate; an oiling device is arranged on the left side of the conveying device; and the oiling device is mounted on the left side of the upper end of the bottom plate. The problems that existing hot-rolled steel plates are usually and directly stacked after rolling molding, heat of the hot-rolled steel plates is not completely dissipated,consequently, deformation and surface oxidation of the stacked hot-rolled steel plates after cooling occur, moreover, when existing hot-rolled steel plates are inconvenient to stack and poor in stacking effect during stacking, gaps between the stacked hot-rolled steel plates is small, and cooling and heat-dissipating performance is poor can be solved, and the process has the advantages of being simple and convenient to operate, good in stacking effect, high in cooling and cooling efficiency and the like.

Description

technical field [0001] The invention relates to the field of hot-rolled steel sheet processing, in particular to a production process for hot-rolled steel sheets. Background technique [0002] Hot-rolled steel plate is made of slab (mainly continuous casting slab) as raw material, after being heated, it is rolled by rough rolling unit and finishing rolling unit. Because hot-rolled steel plate products have high strength, good toughness, easy processing and good shape Excellent properties such as weldability, so it is widely used in manufacturing industries such as ships, automobiles, bridges, construction, machinery, and pressure vessels. With the increasing maturity of new technologies for controlling hot-rolled dimensional accuracy, plate shape, and surface quality, and the continuous emergence of new products, hot-rolled steel sheets and strip products have been more and more widely used and have become more and more powerful in the market. competitiveness. [0003] At ...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that the existing hot-rolled steel plates are usually directly stacked together after being rolled and formed, and the heat of the hot-rolled steel plates is not dissipated, resulting in deformation and surface oxidation of the stacked hot-rolled plates after cooling, and When the existing hot-rolled plates are stacked, the stacking is inconvenient, the stacking effect is poor, the gaps between the stacked hot-rolled plates are small, and the cooling and heat dissipation performance is poor.
