1. A mechanical stripping method for the iron scale on the surface of steel for wire making comprises the air-cooling process control step, and is characterized in that the control parameters of the step are as follows: the opening degrees of the baffles of the No. 1-No. 13 fans are all 50%, the basic speed of the roller way is 0.8m/s, the starting speed of the roller way is 0.7 m/s-1.1 m/s, the final speed is 1.2m/s, the No. 1-No. 6 heat preservation covers are fully opened, and the No. 7-No. 10 heat preservation covers are fully covered.

Technical Field

The invention relates to a mechanical stripping method for iron scale on the surface of steel for wire making.

Background

The steel for wire making is mainly LS and welding rods at home, and the traditional method for removing the iron oxide scales is mostly acid washing, which causes great harm to the bodies of workers and the field environment.

Disclosure of Invention

The invention aims to provide a mechanical stripping method for the iron oxide scale on the surface of steel for wire making, which replaces the traditional pickling method with the mechanical stripping of the iron oxide scale, thereby saving the labor cost and reducing the pollution to the environment.

The mechanical stripping method for the iron scale on the surface of the steel for wire making comprises an air cooling process control step, wherein the control parameters of the step are as follows: the opening degrees of the baffles of the No. 1-No. 13 fans are all 50%, the basic speed of the roller way is 0.8m/s, the starting speed of the roller way is 0.7 m/s-1.1 m/s, the final speed is 1.2m/s, the No. 1-No. 6 heat preservation covers are fully opened, and the No. 7-No. 10 heat preservation covers are fully covered.

The speed of the air cooling line roller way is recalculated and set, and the opening degree of the fan is calculated by combining the cooling rate of the steel for wire making, so that the domestic natural cooling process convention is broken through, the iron scale on the surface of the steel for wire making is completely peeled off, and the steel for wire making is beneficial to being used in field drawing.

Detailed Description

A mechanical stripping method for iron scale on the surface of steel for wire making comprises the air cooling process control step, and the control parameters of the step are as follows: the opening degrees of the baffles of the No. 1-No. 13 fans are all 50%, the basic speed of the roller way is 0.8m/s, the starting speed of the roller way is 0.7 m/s-1.1 m/s, the final speed is 1.2m/s, the No. 1-No. 6 heat preservation covers are fully opened, and the No. 7-No. 10 heat preservation covers are fully covered.

The invention mainly adopts the process design of the whole process of steel rolling for wire making, a method of low-temperature rolling, combination of a pass and a non-pass, a fan using method which breaks through the domestic common practice, and a method of small air volume of the fan and roller way speed increasing, so that iron scales which are easy to peel off are formed on the surface of steel.
