A kind of preparation method of 304 wear-resistant stainless steel wire

Abstract

The invention discloses a manufacturing method of a 304 wear-resistant stainless steel wire. The manufacturing method comprises the following steps that 1) a raw material 304 stainless steel wire material with the diameter of 1.3 times larger than the preset diameter of a finished product is selected; 2) annealing is carried out on the 304 stainless steel wire material; 3) multi-pass drawing treatment is carried out on the annealed stainless steel wire material, if the size of the finished product is reached, the finished product is obtained, if the size is not the size of the finished product, annealing is carried out again, air cooling is carried out on the annealed stainless steel wire material until the temperature of the steel wire material reaches the room temperature, and the stainless steel wire material subjected to drawing and annealing is obtained; 4) the diameter of the stainless steel wire material subjected to drawing and annealing is 1.3 times larger than the preset diameter of the finished product, the step 3 is repeated until the diameter of the stainless steel wire subjected to drawing and annealing is 1.3 times less than or equal to the preset diameter of the finished product, and then the step 5 is carried out; and 5) drawing treatment is carried out on the stainless steel wire material subjected to drawing annealing to reach the size of the finished product, and the 304 wear-resistant stainless steel wire finished product is manufactured. According to the 304 wear-resistant stainless steel wire finished product manufactured by the method, the tensile strength is improved by 1-3 times, the micro vickers hardness is improved by 2-3 times, and the wear performance is improved by 5-30%.

Description

technical field [0001] The invention belongs to the technical scope of producing wear-resistant stainless steel wire, and in particular provides a preparation method of 304 wear-resistant stainless steel wire. Background technique [0002] Wear-resistant steel wire screens, sieve plates and other products used in deep well and deep sea development are often used in special environments such as high grinding and corrosion for a long time, and the product life is often short, and their insufficient performance has become an important factor affecting modern mining efficiency. Therefore, how to select and improve the wear resistance of wire to increase its working life is of great significance to engineering production. Due to its strong work hardening tendency and excellent corrosion resistance, 304 stainless steel is one of the best choices for wear-resistant steel wire screens, sieve plates and other products. [0003] The performance and quality of 304 wear-resistant stain...

Problems solved by technology

[0004] However, the wear-resistant steel wire produced by hot rolling or conventional drawing method has disadvantages, because this kind of wear-resistant wire has been exposed to high temperature and corrosive environment for a long time, the production practice shows that the traditional hot-rolled wear-resistant The life of steel wire products is very short, and the life of wear-resistant steel wire obtained by conventional drawing will be longer than that of hot-rolled wear-resistant steel wire, but the potential of the material itself is still not exerted
