Problems solved by technology

However, from the perspective of operation practice, the service life of the former is only 0.5 to 1 year, and the splint is prone to plastic deformation during use, which affects the operation of the mill; while the latter adopts bimetallic composite casting, its casting quality is not easy to control, and its use effect is not good. not ideal

Abstract

The invention belongs to the technical field of abrasion-resistant materials, and particularly relates to an abrasion-resistant clamping plate and a preparation method thereof. The abrasion-resistantclamping plate is prepared from the following chemical components in percentage by weight: 1.5-2.9% of carbon, 0.4-0.8% of silicon, 0.4-0.85% of magnesium, 0.4-1.0% of manganese, 14-17% of chromium, 0.5-1.0% of molybdenum, 0.1-0.22% of nickel, 0.05-0.20% of titanium, 0.005-0.04% of phosphorus, 0.005-0.04% of sulfur, and the balance of iron. The abrasion-resistant clamping plate is reasonable in formula, easy to manufacture and long in service life, and has quite high strength, toughness, abrasion resistance and impact resistance, the frequency for replacing the clamping plate in a factory is decreased, and the labor intensity is lowered.

Description

technical field [0001] The invention belongs to the technical field of wear-resistant materials, in particular to a wear-resistant splint and a preparation method thereof. Background technique [0002] In addition to bearing the impact and wear of the grinding body and the material, the mill splint also has the function of lifting the grinding body. With the rapid development of material grinding technology, the mill tends to be larger, and higher requirements are placed on the performance of the plywood material. Improving its wear resistance is the focus of research. After more than 30 years of development, the splint material has experienced the development stages of high-manganese steel, ordinary white cast steel, nickel-hard cast iron, high-chromium white iron, modified high-manganese steel and various quenching and tempering processes. . At present, most of the splints of domestic large mills are made of high manganese steel, and some of them are made of high chromiu...
