Based on the new equilibrium solidification theory, the dispersed gate with flat 、 thin and wide rise neck, coupled with cold iron and warming riser, was adopted in the new gating system. 新工艺利用均衡凝固理论,采用短、薄、宽内浇道分散引入,配合冷铁和保温冒口,加大激冷度,强化补缩;
The changes of place and size of casting hot spot with the time are based on structure of casting, material of mould and the position of gate and riser. 热节的位置、大小受铸件结构、铸型材质和浇冒口系统的开设位置所影响。
