Wire drawing production system and production technology for steel wire of steel strand

Abstract

The invention relates to a wire drawing production system for a steel wire of a steel strand. The wire drawing production system for the steel wire of the steel strand comprises a pay-off rack, a wire managing rack, an aligning and guiding device, a physical unshelling device, a descaling and grinding device, a film coating device, a drying device, multiple drawing devices and a take-up rack which are sequentially arranged. The descaling and grinding device comprises a box body. A pair of vertical brush wheel assemblies and a pair of horizontal brush wheel assemblies are arranged inside the box body. An electrical machine drives brush wheels of the vertical brush wheel assemblies and brush wheels of the horizontal brush wheel assemblies. The outlet terminal on the right side of the box body is provided with a dust absorbing device. The film coating device comprises a box body, a cleaning mechanism and a film coating mechanism. A baffle is arranged inside the box body. The box body is divided into the cleaning mechanism arranged on the left inlet end and the film coating mechanism arranged on the outlet end on the right side of the box body. The wire drawing production system and a production technology for the steel wire of the steel strand have the advantages that the structure is simple, the design is scientific and reasonable, and the system running is safe, efficient and stable. The quality of the steel wire is improved and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of steel strand steel wire production and processing, in particular to a steel strand steel wire drawing production system and production process. 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 poor pay-off effect of wire rod, 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 die and ...

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, causing hydrogen embrittlement, affecting the mechanical properties, and greatly reducing the toughness and strength of the steel wire after drawing; the speed of each wire rod drawing process cannot be adjusted , affecting the drawing quality of steel wire
