Balls, grinding balls, grinding balls, forged steel balls, hot rolled steel balls all dimensions Casting Steel Co., Ltd. Gong Xuemei: 13953120393 forged steel ball: good surface quality, good impact resistance, toughness, wear resistance, not broken and out of round. The heating temperature of the metal is 700-1300 ℃, by forging mechanical pressure is applied to the metal blank, so that it is plastically deformed to obtain a certain mechanical properties, shape and size of the forging certain processing methods. Two forging (forging and stamping) is one of the components. By forging can eliminate metal produced in the smelting process cast loose and other defects, optimize the microstructure, and because the preservation of a complete line of metal flow, the mechanical properties are generally better than the same material forgings castings. Related mechanical load is high, harsh working conditions of the important parts, in addition to simple shapes available rolled sheet, profiles or welded parts, the use of forgings. In addition, you want to wear and forged steel ball must choose the most wear-resistant material, such as the national standard 60Mn, 65Mn, and suggested the use of national production of large steel mills, the same kind of material, quality of steel produced in different also ranging, and the quality is good or bad quality of forging 80% depending on the material, such as the use of high-manganese steel, impact resistance, toughness, wear resistance, not broken. Forged steel balls because they are inexpensive, economical and durable favored by the majority of users, such as the international mining giant Rio Tinto, BHP Billiton, Anglo Gold all use forged steel balls.
