Taking a coal mill as an example, in the actual service process, the coal mill is not only in the severe working condition environments such as high-temperature oxidation, corrosion and high impact, but also is worn by hard grinding materials, so that the parts are quickly failed due to wear. The severe abrasion causes a large amount of metal loss, and the rapid failure of parts due to abrasion needs to consume a large amount of manpower and material resources for frequent replacement, so that the production is stopped and the cost is increased, which has great adverse effects on the production efficiency and the economic benefit of enterprises.
At present, the wear-resistant parts of the coal mill are produced and prepared by methods such as integral casting molding, surface overlaying or integral overlaying of high-chromium cast iron and the like in China. The prior grinding roller wear-resistant material is represented by high-chromium cast iron and various alloy steels, the whole wear-resistant material has the characteristics of high hardness, good wear resistance and greatly improved toughness, the hardness values of the wear-resistant material are generally more than HRC56, but the service requirements of a single alloy material are gradually difficult to meet due to the harsh environmental conditions.
