Film coating device for steel stranded steel wire drawing and using method

Abstract

The invention relates to a film coating device for steel stranded steel wire drawing. The film coating device comprises a box body, a cleaning mechanism and a film coating mechanism, wherein a partition plate is installed in the box body so as to divide the box body into the cleaning mechanism located at the wire inlet end of the left side and the film coating mechanism located at the wire outlet end of the right side of the box body. High-pressure water can thoroughly remove tiny particles on the surface of a rolled steel wire, and a good foundation is laid for follow-up film coating work. After the rolled steel wire passes through the film coating mechanism, a protective film is formed on the surface of the rolled steel wire and is used for protecting the rolled steel wire against scratching and enabling the surface of the rolled steel wire to be evenly coated with an adhesive agent carrier in the rolled steel wire drawing process, the coating of the adhesive agent is loose and porous and has rough surface, and the capacity of attaching to a dry powder lubricant of the coating is very high. Therefore, friction force between the small rolled steel wire and a mold is reduced, drawing force is reduced, energy consumption is reduced, and the service life of the mold is prolonged. The adhesive agent carrier produces physical absorption, has the advantages of being simple in operation and short in proposal time, and adhesive agent resources are rich and low in cost.

Description

technical field [0001] The invention belongs to the technical field of production and processing of steel strand steel wires, in particular to a film coating device and application method for drawing steel strand steel wires. Background technique [0002] Steel wire drawing refers to a process in which the raw material of the wire rod is subjected to pickling, phosphating, drawing, winding and other processes, during which one or more drawing is carried out to make it reach the target diameter. The current steel wire drawing production system includes pay-off device, pickling device, wire drawing device, wire take-up device, etc. In the process of production and processing, there are problems such as low wire rod pay-off efficiency, easy knotting, acid discharge and environmental pollution. [0003] In addition, during the drawing process of the wire rod, the radial compressive stress in the deformation zone is very large, and there are two peaks, one at the entrance of the ...

AI Technical Summary

Problems solved by technology

The problems existing in this system are: the pay-off frame is a drum structure, which cannot realize continuous pay-off, which affects the working efficiency of the whole system; the oxide layer on the surface of the wire rod is removed by pickling, and in addition to the discharge of waste liquid to pollute the environment, the acid The liquid will also penetrate into the inside of the wire rod, destroying the molecular structure of the wire rod, and greatly reducing the toughness and strength of the steel wire after drawing; the speed in each wire rod drawing process cannot be adjusted, which affects the drawing quality of the steel wire
