基于AnyCasting的齿圈座铸钢件发热保温冒口设计

摘要

介绍了基于CAE的冒口设计方法,针对传统的冒口设计方法中存在的不足,采用AnyCasting铸造模拟软件对某厂生产的挖掘机齿圈座铸钢件发热保温冒口进行模拟.根据模拟所得的铸件凝固时间直接计算冒口模数,并利用补缩液量法校核冒口体积并确定冒口的数量.生产验证表明,该工艺设计的发热保温冒口补缩效果良好与模拟结果相符,既保证铸件无缩孔缺陷,又提高了工艺出品率.%The design method of the riser based on the computer aided engineering technology, was introduced in the article. Aiming at the disadvantages of the design method of traditional riser, the casting process of exothermic and insulating riser for steel casting of gear ring seat of excavator was simulated by AnyCasting software. The riser modulus was directly calculated according to the solidification time of the casting by the simulation. Meanwhile its volume and quantity could be confirmed by the method of feeding liquid. The result shows that the feeding effect of the exothermic and insulating riser is perfect, which is consistent with the simulation result. The method can not only ensure no shrinkage defect in the casting, but also improve the yield.
