Heat treatment process for anti-rust and anti-corrosion steel

Abstract

The invention discloses a heat treatment process for anti-rust and anti-corrosion steel. The heat treatment process includes the following steps of S1, selecting proper steel materials and cleaning the steel materials, wherein rusty spots on the steel material that is hard in texture shall be wiped out by steel wires, the steel material that is low in hardness shall be wiped by cotton cloth, and after the surfaces of the steel materials are cleaned, tempering treatment is performed on the steel materials; and S2, performing quenching treatment on the steel materials through a chamber electricfurnace, selecting a proper quenching temperature of 850 DEG C for quenching the steel materials and performing quenching heat preservation for 20-25 min. The heat treatment process is simple in process; by performing normal tempering treatment on the steel materials, the steel materials may have high structural stability and structural strength; and moreover, by performing salt bath tufftriding treatment, vacuum zincizing treatment and finish painting treatment on the steel materials in the heat treatment process, the steel materials may have good anti-corrosion and anti-rust effects, the performance of the steel materials is effectively improved, and the service life of the steel materials is prolonged.

Description

technical field [0001] The invention relates to the technical field of steel heat treatment, in particular to a heat treatment process for rust-proof and anti-corrosion steel. Background technique [0002] The heat treatment of steel refers to heating the steel workpiece in a certain medium to a suitable temperature, and keeping it at this temperature for a certain period of time, and then cooling it in a different medium at different speeds. A process that controls its performance by microstructure; heat treatment can give full play to the potential of steel, improve the performance of the workpiece, reduce the weight of the workpiece, save materials, reduce costs, and prolong the service life of the workpiece. [0003] In the steel heat treatment process in the prior art, when the steel needs to be water-cooled during the processing process, the cooling rate of the steel is relatively slow, thereby affecting the performance of the steel; at the same time, the steel is anti...

AI Technical Summary

Problems solved by technology

[0003] In the steel heat treatment process in the prior art, when the steel needs to be water-cooled during the processing process, the cooling rate of the steel is relatively slow, thereby affecting the performance of the steel; at the same time, the steel is anti-corrosion and anti-rust during the heat treatment process. The treatment process is poor, so it is necessary to design a heat treatment process for anti-rust and anti-corrosion steel
