Technical Field

The invention relates to a wear-resistant steel; belongs to the field of mold manufacturing.

Background

Wear is one of the main forms of workpiece failure, and the wear causes a large consumption of energy and raw materials, and 1/3 to 1/2 of the energy are consumed in friction and wear according to incomplete statistics; therefore, the development of wear-resistant steel is provided; the wear-resistant steel is various in types and can be roughly divided into high-manganese steel, medium-low alloy wear-resistant steel, chrome-molybdenum-silicon-manganese steel, cavitation erosion resistant steel, wear erosion resistant steel, special wear-resistant steel and the like; some general alloy steels such as stainless steel, bearing steel, alloy tool steel, alloy structural steel and the like are also used as wear-resistant steel under specific conditions, and because of convenient sources and excellent performance, the general alloy steels also occupy a certain proportion in the use of the wear-resistant steel; the wear-resistant steel is widely applied to mining machinery, coal mining and transportation, engineering machinery, agricultural machinery, building materials, electric machinery, railway transportation and other departments. For example, steel balls, liners of ball mills, teeth and buckets of excavators, rolling mortar walls, toothed plates, hammers of various crushers, track plates of tractors and tanks, striking plates of fan mills, railroad frog, middle trough plates, ledges, link chains of coal mine scraper conveyors, blades and teeth of bulldozers, liners of large electric wheelers, roller bits for oil and open cast iron piercing, and the like, and grinding media (balls, rods and liners) used in ore and cement mills are steel wear parts with a large consumption. In the united states, grinding balls are mostly forged or cast from carbon and alloy steels, which account for 97% of the total grinding ball consumption. In canada, 81% of the balls are consumed. According to statistics at the end of the 80 s, China consumes about 80-100 million t of grinding balls each year, and the annual consumption of the lining plates of the national mills is nearly 20 million t, wherein the vast majority of the grinding balls are steel products. 6-8 million tons of steel plates are consumed in the middle groove of the scraper conveyor for the Chinese coal mine every year, and the conventional wear-resistant steel on the market has poor toughness and comprehensive wear resistance, excessive alloy elements, difficult processing and high production and processing cost.

Disclosure of Invention

In order to solve the problems, the invention aims to provide the wear-resistant steel which has the advantages of good wear resistance, long service life, good mechanical property and low production cost.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows: the wear-resistant steel comprises the following chemical components in percentage by weight: 0.55-0.7% of C, 2.2-3.6% of Cr2, 2.2-2.8% of Mn2, 0.5-0.9% of Si, 0.2-0.4% of Sb0.25-0.55% of Mo0.08-0.1% of Re0.08-0.1%, 0.05-0.1% of Ti0.05%, less than or equal to 0.05% of S, less than or equal to 0.05% of P and the balance of Fe.
