Anti-abrasion non-magnetic stainless steel wire special for washing screen and preparation method thereof

Abstract

The invention provides an anti-abrasion non-magnetic stainless steel wire special for a washing screen and a preparation method thereof. The anti-abrasion non-magnetic stainless steel wire comprises the components of, by mass, 0.06-0.15% of C, 0.5-1.0% of Si, 6.0-17.0% of Mn, 0.040% of P, 0.03% of S, 17-23.5% of Cr, 1.3-13% of Ni, 0.15-2.5% of Mo, 0.3-1.5% of Cu, 0.15-0.6% of Ti, 0.15-0.75% of N and the balance Fe. According to the anti-abrasion non-magnetic stainless steel wire, through reasonable proportion and a machining technology, a product is good in abrasion resistance, low in magneticconductivity, excellent in weldability, good in machining ductility, high in cost performance and long in service life and meets all requirements, and the anti-abrasion non-magnetic stainless steel wire is a novel special super anti-abrasion stainless steel wire urgently needed by the washing industry.

Description

Technical field: [0001] The invention relates to a special wear-resistant and non-magnetic stainless steel wire for washing screens and a preparation method thereof, belonging to the technical field of steel wire materials and processing. Background technique: [0002] Stainless steel wire is widely used in mining, petroleum, chemical, food, medicine, machinery manufacturing and other industries. Stainless steel wire can not only make stainless steel mesh, but also make various other stainless steel products. The performance of stainless steel wire directly affects the performance of its products. With the development of the times, various types of stainless steel have appeared on the market. In recent years, my country's washing industry has developed rapidly, especially the popularization and application of intermediary coal washing technology, which has enabled the washing industry to achieve leapfrog development and narrowed the gap with foreign counterparts.

AI Technical Summary

Problems solved by technology

Stainless steel screen is an important part of intermediary coal washing. Stainless steel wire must be used to manufacture stainless steel screen. However, the stainless steel wire on the market can no longer meet the performance requirements of the screen, which seriously lags behind the progress of the industry. There are many problems, such as: poor wear resistance, Short service life; magnetic, intermediary coal washing cannot be used; poor weldability, weak solder joints, insufficient strength, easy to open welding; poor ductility and toughness, cold-rolled sieves are brittle; uneven hardness, sieve width varies ; Low cost performance, low profit, unable to meet the requirements

[0003] Reasons for the above problems: impure raw materials and many impurities, unscientific content ratio, obsolete smelting equipment, no forging of steel ingots to loose the steel wire structure, poor control of rolling process, inadequate wire drawing and solution treatment, deep processing of round wire The means are backward, and the special-shaped wire has not been cured with wear-resistant layer
