A process for treating the oxide layer on the surface of hot-rolled section steel

Abstract

The present invention relates to a process for treating the oxide layer on the surface of hot-rolled profiled steel, and specifically relates to a device for treating the oxide layer on the surface of hot-rolled profiled steel, which includes a profiled steel conveying mechanism, a bottom end surface processing mechanism, an adjusting and lowering frame mechanism, an inner end surface processing mechanism and a side surface treatment mechanism. Wall surface treatment mechanism; the treatment device involved in the treatment process provided by the present invention can realize the automatic treatment of the oxide layer on the surface of T-shaped steel under the premise of ensuring that the oxide layer on the surface of T-shaped steel is basically treated thoroughly, which solves the problem of manual processing, which is labor-intensive and difficult to deal with. Low efficiency and close contact with grinding powder affect health. The processing process is more labor-saving, greatly reducing labor intensity, improving processing efficiency, and maintaining physical health 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.
