Description

technical field [0001] The invention relates to the technical field of surfacing materials, in particular to a wear-resistant grinding roller. Background technique [0002] The grinding device is one of the important equipment widely used in metallurgy, mining, cement, chemical industry and other industries, and the grinding roller and squeeze roller are the key components of the grinding equipment. During use, it is easily lost due to wear and tear, which increases the cost. Therefore, improving the material of grinding rollers and increasing their service life have become the focus of research and development in the field of new materials all over the world. [0003] At present, in the field of grinding roller manufacturing, welding wire materials with high hardness, high wear resistance and high impact resistance are generally used to surfacing the surface of the grinding roller to improve the wear resistance of the grinding roller. After the surface of the grinding rol...
