Problems solved by technology

[0004] The production method of Z-shaped special-shaped steel wire in the prior art, such as Chinese patent application (publication number is CN111036697A), but the production method of Z-shaped special-shaped steel wire in the prior art cannot overcome the impact of special-shaped wire drawing die on hot-dip galvanizing or zinc-aluminum hot-dip galvanizing. The continuous deformation of the product affects the mechanical properties of the Z-shaped special-shaped steel wire, and the generated Z-shaped special-shaped steel wire has high brittleness, low product strength and torsional strength, which cannot meet the requirements and use of users.

Abstract

The invention relates to the technical field of steel wire production, in particular to a Z-shaped special-shaped steel wire production method. The Z-shaped special-shaped steel wire production methodcomprises the following steps of selecting a to-be-treated round wire coil for feeding, and being subjected to hot dipping; carrying out special-shaped cold rolling by utilizing a cross-shaped rolling mill to generate a finished Z-shaped special-shaped steel wire. Compared with the prior art, according to the Z-shaped special-shaped steel wire production method, the round wire coil raw material steel wire is subjected to hot dipping and then is subjected to special-shaped cold rolling by the cross-shaped rolling mill, so that the influence of thermal stress generated by hot dipping on the mechanical property of the Z-shaped special-shaped steel wire and the brittleness of the finished Z-shaped special-shaped steel wire are reduced, the hardness of a hot-dip coating of the finished Z-shaped special-shaped steel wire and the bending strength, the twisting strength, the corrosion resistance and the wear resistance of the finished Z-shaped special-shaped steel wire are improved, and therefore the finished Z-shaped special-shaped steel wire is smooth in surface and convenient to twist and process.

Description

Technical field [0001] The present invention relates to the field of wire production techniques, and more particularly to a Z-shaped wire production method. Background technique [0002] With the advancement of technology, the consumption of wire ropes is constantly growing, and users' quality requirements and performance requirements for wire rope are getting higher. Among them, the shaped steel wire can meet the quality requirements and performance requirements of wire wire, and the use of shaped wire is widely used. It mainly has mechanical processing industries, textile industries, sealing wire ropes, structural steel wires and nail steel wires. [0003] The shaped steel wire refers to a non-circular steel wire in cross section. Includes flat, rectangular, elliptical, square, triangular, trapezoidal, Z-shaped and other special section. The shaped steel wire has a steel wire having a specific shape section other than the circular. Common shaped steel wires have square shapes, ...
