Preparation process of cutting steel wire with tiny corrugations

Abstract

The invention discloses a preparation process of a cutting steel wire with tiny corrugations, comprising the following steps of: 1, carrying out de-rusting and acid washing on a steel wire rod, and then coating boron and drawing; 2, performing intermediate heat treatment, and then sequentially coating boron and drawing; 3, performing secondary heat treatment, and then electroplating copper, and performing heat diffusion after the electroplating is finished; 4, inspecting the electroplated steel wire, and carrying out wet drawing on the qualified steel wire; and 5, threading the steel wire through a pre-deformation device and carrying out pre-deformation treatment on the steel wire, and then carrying out cold drawing and fine drawing on the steel wire after the pre-deformation treatment. The preparation process disclosed by the invention has the following advantage that an abrasive can be carried well during a cutting work after corrugations are formed on the cutting steel wire, thus greatly increasing cutting efficiency and greatly improving cutting quality.

Description

technical field [0001] The invention relates to a preparation process of a cutting steel wire used for cutting hard and brittle materials such as solar silicon wafers, sapphires, and glass. Background technique [0002] The surface of the currently used cutting steel wire is smooth, and generally a layer of copper, zinc or copper-zinc alloy is electroplated on the surface of the cutting steel wire. The specific production process is as follows: 1. Mechanically derusting the φ5.5 wire rod 1. After electrolytic pickling, boron coating is carried out for the first time, and then wire drawing is carried out for the first time, which is usually called rough wire drawing process; It is the intermediate wire drawing process; 3. Then carry out the second heat treatment, and then carry out copper plating or galvanizing, and conduct thermal diffusion after the electroplating is completed; 4. Inspect the steel wire after electroplating, and carry out wet drawing on the qualified steel...

AI Technical Summary

Problems solved by technology

The surface of the above-mentioned conventional cutting steel wire is too smooth, and cannot carry the abrasive well when cutting hard and brittle materials such as silicon wafers, sapphire, glass, etc., resulting in low cutting efficiency
