Impurity: be not more than 0.003%
All the other are Fe.
A kind of major diameter abrasion-proof steel ball production technique may further comprise the steps:
1) it is for subsequent use that the square steel that will be made by above-mentioned abrasion-proof steel ball material or round steel are cut into the ball material by certain length, then, puts into the process furnace homogeneous heating, Heating temperature to 900 ℃-1050 ℃;
2) the ball material being put into forging roll, is in 750 ℃ of-900 ℃ of environment in temperature, is forged into steel ball;
3) steel ball is put into WATER AS FLOW MEDIUM and heat-treat, when temperature was 300 ℃-350 ℃, the steel ball water outlet entered the waste heat tempering unit, slow cooling to 30 ℃-60 ℃, i.e. and preparation is shaped.
Further, to put into the heat treated temperature of WATER AS FLOW MEDIUM be 450 ℃ to steel ball;
Further, to carry out the time of slow cooling be 48 hours to steel ball;
The beneficial effect that the present invention produces is, 1, forges playing skill art index according to international state-of-the-art major diameter (120mm-200mm), in conjunction with domestic existing steel-smelting technology and noble metal mineral resources condition advantage, develop the material that surpasses domestic excellent carbon alloy steel, form and to be lower than 1/5th, the product cost competitive power after increase utilizes; 2, will have roll forging steel ball automatic production line now, after present technique is combined, can produce the leading wear-resistant forged steel ball of novel, efficient major diameter in domestic and international market, fill the domestic gaps, and satisfy domestic and international large-size ball mill installation and use.
