Description
High-chromium steel balls are produced by medium-frequency electric furnace melting, metal mold or sand casting, so domestic wear-resistant material manufacturers often call them high-chromium alloy cast balls. Steel balls with chromium content ≥10.0% and carbon content between 1.80% and 3.20% are all high-chromium balls. The national standard requires that the hardness of high-chromium balls (HRC) must be ≥58 degrees. Heat treatment and quenching must be used. At present, there are various quenching methods for high chromium balls at home and abroad, such as oil quenching, air quenching, and water solution.
High chromium steel balls are widely used in metallurgical mines, cement building materials, thermal power generation, flue gas desulfurization, aerated concrete, magnetic materials, chemical industry, coal-water slurry, pellets, slag, ultrafine powder, fly ash, calcium carbonate, Quartz sand and other industries.
