The forged steel grinding ball is excellent in surface quality, toughness, and resistance to impact and abrasion. It won't crack and lose circularity easily. The forging and stamping method that we use is that heating the metal until the temperature reaches 1050ºc (±50 ºc), and utilizing the metalforming machinery to exert pressure onto the metal blank, then the metal blank coming out with plastic deformation to become the forge piece with certain mechanical properties, shape and dimension. The forging can eliminate the defects such as porous as-cast microstructure generated during the smelting process of the metal, and optimize the microstructure. Meanwhile, as a result of the preservation of the complete metal flow line, the forge piece has superior mechanical performance to the casting with the same material. The forged steel grinding ball must use the super wear resistant material to ensure the abrasion resistance, such as the high-carbon steel materials compliant with the national standard, or the high wear resistant alloy steel material researched and developed independently by some companies themselves.
1)hardness Surface hardness of forged ball ranges from hrc55 to hrc67. Core hardness of forged ball ranges from hrc50 to hrc55. Average volume hardness (avh) ranges from hrc55 to hrc63. All requirements about hardness can be customized according to different grinding condition. 2)density Average density is 7.85g/cm3. Consistency is higher than ordinary ones. 3)component analysis Raw material is high carbon alloy steel, and the promotion of alloy elements is under 5%. 4)impact value Impact toughness value is more than 12j/cm2 5)metallographic structure Tempered martensite forms when tempered. The best microstructure is fine needle martensite. 6)breakage rate Actual breakage rate is not greater than 0.5% and close to 0. 7)raw material As we know, the quality of forged grinding piece depends on the material by 80%. Our products use high-quality round steel from national large-scale steel mill to insure the quality of our products.
