Problems solved by technology

Generally speaking, the higher the hardness, the better the wear resistance, and the wear resistance has a great influence on the wear resistance of the equipment. At present, the common material used to make cylinder liners and grinding discs is mostly KmTBCr26. Although this material It also has good corrosion resistance and high temperature oxidation resistance, and can also adapt to abrasive wear with large impact loads. The Rockwel

Abstract

The invention discloses a cast iron material with higher hardness, corrosion resistance, high-temperature oxidation resistance and abrasion endurance of an abrasive material with larger impact load. The cast iron material consists of the following compositions by weight percentage: 2.8 percent of C, 0.2 to 1.0 percent of Si, 0.5 to 1.0 percent of Mn, less than or equal to 0.06 percent of S, less than or equal to 0.1 percent of P, 21 to 23 percent of Cr, 0 to 1.5 percent of Ni, 1.0 to 1.5 percent of Mo, and the balance being Fe and unavoidable impurities. The cast iron material has the advantages of improving hardness and other comprehensive performances of the material, and being helpful for prolonging the service life of a finished product manufactured by the cast iron material.

Description

technical field [0001] The invention belongs to the field of cast iron. It is especially suitable for making wear-resistant parts with very harsh working environment in metallurgy and other fields. Background technique [0002] With the rapid development of paint, pigment, cosmetics and other industries, grinding equipment is used more widely and more frequently. The quality of the grinding equipment and the grinding effect often depends on the quality of the cylinder liners and grinding discs used. Generally speaking, the higher the hardness, the better the wear resistance, and the wear resistance has a great influence on the wear resistance of the equipment. At present, the common material used to make cylinder liners and grinding discs is mostly KmTBCr26. Although this material It also has good corrosion resistance and high temperature oxidation resistance, and can also adapt to abrasive wear with large impact loads. The Rockwell hardness of its cast shape can generally...
