Description

Technical Field

[0001] The invention relates to the technical field of hot-rolled plate production in a steel rolling mill, and in particular to a device for controlling iron oxide scale on the surface of a hot-rolled plate used in the production of a steel rolling mill. Background Art

[0002] A rolling mill is a device that realizes the metal rolling process. It generally refers to the equipment that completes the entire process of rolled material production, including main equipment, auxiliary equipment, lifting and transportation equipment, and ancillary equipment.

[0003] Steel rolling methods can be divided into hot rolling and cold rolling according to the rolling temperature, longitudinal rolling, transverse rolling and oblique rolling according to the relative motion relationship between the workpiece and the rollers during rolling, and general rolling and special rolling according to the forming characteristics of the rolled products. Cycle rolling, spin rolling, bending forming, etc. are all special rolling methods.

[0004] my country's large steel mills have been using advanced continuous rolling mills since the 1970s. The continuous rolling mills have adopted a complete set of advanced automatic control systems. The entire production process and operation monitoring are implemented by computer control. The rolled products are rolled on several rolling mills at the same time, which greatly improves production efficiency and quality.

[0005] The transmission arm of the rolling mill used in existing steel mills is directly exposed to the outside due to considerations of heat dissipation and cost. The steel rolling environment will generate a large amount of dust that falls on the outside of the transmission arm structure, causing the transmission arm to gradually adhere to dust and moisture, resulting in rust and reducing its service life. In addition, the long-term rotation and rolling work of the rollers will cause greater friction between the rotation of the rollers and the brackets, affecting the normal operation of the rollers. The used rolling mills will generate a large amount of smoke and a small amount of dust, which generally have no treatment device and need to be naturally dusted or dispersed, which is very time-consuming and labor-intensive.
