Hot-rolled section steel surface oxidation layer treatment process

Abstract

The invention relates to a hot-rolled section steel surface oxidation layer treatment process, in particular to a hot-rolled section steel surface oxidation layer treatment device which comprises a section steel conveying mechanism, a bottom end surface treatment mechanism, an adjusting lifting frame mechanism, an inner end surface treatment mechanism and a side wall surface treatment mechanism. According to the treatment involved in the treatment process, on the premise of ensuring that the oxidation layer on the surface of T-shaped steel is basically completely treated, automatic treatment of the oxidation layer on the surface of the T-shaped steel can be realized, the problems that the manual treatment labor intensity is high, the treatment efficiency is low and short-distance contact of grinding powder influences the body health are solved, the treatment process is more labor-saving, the labor intensity is greatly reduced, the treatment efficiency is improved, and the body health is maintained to a certain extent.

Description

technical field [0001] The invention relates to the technical field of profiled steel treatment, and specifically proposes a process for treating an oxide layer on the surface of a hot-rolled profiled steel. Background technique [0002] Steel products of various geometric cross-sectional shapes rolled from heated billets. According to the shape of the steel section, it can be divided into three types: simple section, complex section or special-shaped section and periodic section; the complex section includes angle steel, I-beam, channel steel, T-beam, H-beam, Z-beam, rail, steel plate Pile, window frame steel and other miscellaneous section steel; T-shaped steel is also called T-shaped steel, which has been widely used in the fields of machinery and construction. The hot-rolled T-shaped steel is easy to oxidize and rust on its surface during long-term stacking and transportation. If the T-shaped steel cannot be disposed of in time once it is rusted, it will inevitably rust...

AI Technical Summary

Problems solved by technology

[0003] Once the T-shaped steel is rusted, the entire surface will be covered with an oxide layer, and the traditional process of using tools to remove rust basically relies on manual processing, which is labor-intensive and inefficient, and in order to ensure the derusting If the rust is relatively thorough, the T-shaped steel has to be turned over, which is very laborious. In addition, grinding during manual processing will cause close contact with the oxide layer powder produced by grinding, which is likely to affect the health of the operator.
