Description
Wear-resistant steel balls, also known as grinder wear-resistant media, are consumables whose main purpose is to grind materials so that they can be ground finer to meet the standard of use. Mainly used in mines, power plants, cement plants, steel plants, silica sand plants, coal chemical and other fields. The world's annual consumption is more than 30 million tons, and China's consumption is between 3 million and 5 million tons, which is the largest consumption of steel balls.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.
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.
