Abstract

The invention discloses an anti-oxidation treatment process for the surface of a steel pipe. The anti-oxidation treatment process comprises the following steps: S1, preparing raw materials; s2, aluminum, silicon, aluminum trioxide, carbon, aluminum silicate and magnesium hydroxide are sintered in a sintering furnace; s3, performing cold shock treatment to obtain particles, and grinding the particles into powder; s4, adding a powdery material obtained by grinding aluminum, silicon, aluminum trioxide, carbon, aluminum silicate and magnesium hydroxide into a mixer, adding a binder and water, and stirring and mixing to obtain a coating; s5, the surface of the steel pipe is evenly coated with the coating, and drying is conducted; s6, transferring the steel pipe into a heating furnace, and heating in an inert gas atmosphere; and S7, the steel pipe is taken out, quenched and dried, and treatment is completed. The problems that in the heating machining process of the steel pipe, the steel can react with oxidizing gas in a heating furnace, an oxidation layer is formed on the surface of the steel pipe, the quality of the steel pipe is reduced, and resources are wasted are solved.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to an anti-oxidation treatment process for the surface of a steel pipe.
