- 摘要:
- 大型设备需用3根空心特种合金钢轴,采用直立侧注阶梯浇注工艺的消失模铸造。当钢液从圆柱的一侧注入时,注入钢液的一侧,比远离内浇口的对称一侧温度要高,两侧的收缩量不同,将导致铸件弧形变形。"金龙攀玉柱"浇注系统采用旋转弧形曲线侧注,通过流场的调节,使热场合理分布,有效的解决了空心轴的变形问题。
Three hollow special alloy steel shafts were needed for large equipment.Lost foam casting by vertical side casting step casting process.When the molten steel was injected from one side of the cylinder,the temperature of the injected side of the molten steel was higher than that of the symmetrical side far from the inner gate,and the shrinkage of both sides was different,which would lead to the arc-shaped deformation of the casting.The results show that the"golden dragon climbing jade column"spiral pouring system adopts the side injection of rotating arc curve,the heat field is reasonably distributed through the regulation of flow field,and the deformation problem of hollow shaft is effectively solved.
