- 摘要:
- 圆锥破碎机主轴副材质为ZG350,有4种规格,重950~3 560 kg。采用消失模铸造工艺,大头在下,立浇,顶部设置3个发热保温冒口,直浇道折弯设置于铸件顶部的翼板上,钢液通过铸件的型腔充填铸件,即借用型腔做浇道工艺。结果表明,浇注系统极度简化,工艺出品率达到80%。铸件机加工后无缺陷,为消失模铸钢工艺提供了一种新思路。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.
