Anti-corrosion method of steel and anti-corrosion steel

Abstract

The invention belongs to the technical field of metal protective materials, and particularly relates to an anti-corrosion method of steel and the anti-corrosion steel. A bluing tank comprises a tank body, a conveyor belt, a sealing cover and an electromagnetic heating device; the tank body is of a cuboid structure with a cavity formed inside; the sealing cover is mounted at the opening in the upper end of the tank body; a feeding hole is formed in one side of the tank body, and a discharging hole is formed in the other side of the tank body; a feeding tank is fixedly connected to the position,outside the feeding hole, of the tack body, and a discharging tank is fixedly connected to the position, outside the discharging hole, of the tank body; the feeding tank and the discharging tank areboth obliquely formed; the electromagnetic heating device is connected to the bottom of the tank body in an embedded manner; guide rods which are uniformly distributed are rotationally connected intothe cavity of the tank body; each guide rod is sleeved with a rotating wheel; the conveying belt meshes with the rotating wheels; and according to the method and the steel, the conveying belt is usedfor driving a component to be subjected to bluing reaction in the slow moving process, the component is automatically turned over in the moving process, and then contact between the component and bluing liquid is uniform.

Description

technical field [0001] The invention belongs to the technical field of metal protection materials, in particular to an anticorrosion method for steel and anticorrosion steel. Background technique [0002] During daily use, the surface of steel materials is often affected by oxygen and then rusts, which not only affects the appearance of steel products, but also affects the structure, size and accuracy of steel structural parts. Use the bluing process to treat the steel surface, thereby forming a protective film of ferric oxide on the surface of the steel structure, and then cooperate with saponification to enhance the anti-corrosion performance of the steel structure surface. Soak in the constant temperature bluing solution, turn the component over at regular intervals, so as to ensure that the surface of the component is in uniform contact with the bluing solution, and then make the oxide film formed on the surface more uniform. After soaking for a period of time, remove th...

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology and solve the bluing treatment of steel, the existing bluing tank is not only time-consuming and laborious to operate, but also the harsh working environment has great obstacles to the operation of the staff, resulting in low efficiency of the bluing process. Low problem, a kind of anti-corrosion method of steel and its anti-corrosion steel that the present invention proposes
