Product Details


Ball Mill Ring Gear is usually adopted 45 steel, but according to the GB/T699-1999 standard, the tensile strength of C45 steel is 600MPa, the yield strength is 355MPa, the elongation is 16%, the section shrinkage is 40%, and the impact work is 39J. According to the 45 steel of GB/T699-1999 standard, the heat treatment system can be recommended for normalizing at 850 C, quenching at 840 C, and tempering at 600 C, and the yield strength is more than 355MPa. The hardness of No. 45 steel quenched and tempered is less than HRC28, which is soft and non abrasion resistant. After quenching, the hardness is greater than HRC55 and wear resistance is better. It is mostly equipped with large equipment such as dryer gear ring and ball mill  ring gear.
