Abstract：
The material of spindle pair of cone crusher is ZG350,there are 4 specifications,and the weight is 950~3 560 kg.EPC process was adopted,the big head was lower,the vertical casting,and the top part was equipped with 3 heating and heat preservation risers.The straight runner was bent on the wing plate at the top of the casting,and the molten steel fills the casting through the mold cavity of the casting.The results show that the casting system is extremely simplified,and the production rate reaches 80%.There is no defect after machining of casting,which provides a new idea for steel technology of EPC process.
