Problems solved by technology

[0002] At present, the production of wire rods for washing machine suspenders requires surface descaling, which requires higher requirements on the structure and composition of the oxide scale on the surface of the wire rod. Improper structure and composition of the oxide scale on the surface of the wire rod will lead to unclean descaling, which will affect the plating quality. Finished surface quality after zinc

Abstract

The invention discloses a production method of a simple pickling wire rod for a hoisting rod of a washing machine. The method comprises the processes of steel blank heating, dephosphorization, rollingand cooling, wherein the heating process is carried out in a two-section heating manner. The method is simple and convenient to operate; raw materials, fuel and auxiliaries are common objects. The method is a novel technology for producing the simple pickling wire rod for the hoisting rod of the washing machine. The method is applicable to hot-rolled circular wire rod being not greater than 10 mmin diameter; the surface oxide scale structure and component of the wire rod are controlled, and thus the surface oxide scale can be conveniently removed under a pickling or mechanical dephosphorization condition. The method is proper in heating temperature, reasonable in cooling after rolling, efficient in production, and high in value of practicability and popularization.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a production method of simple pickling wire rods for washing machine suspenders. Background technique [0002] At present, the production of wire rods for washing machine suspenders requires surface descaling, which requires higher requirements on the structure and composition of the oxide scale on the surface of the wire rod. Improper structure and composition of the oxide scale on the surface of the wire rod will lead to unclean descaling, which will affect the plating quality. Finished surface quality after zinc. The structure and composition of the oxide scale on the surface of the wire rod are mainly related to the final rolling temperature, cooling process, chemical composition of the steel matrix and other factors. In order to ensure that the structure and composition of the oxide scale on the surface of the wire rod are suitable, the method of the present ...
