三、影响模子—绝热垫联接处凝固过程的参数冷隔的形成是凝固壳层的固液界面与模子绝热垫互相作用的结果。如果界面直接同绝热垫接触,那么将形成冷隔。应用另一种方法,如果界面不同绝热垫互相作用,而只同模子接触,则不会形成冷隔。在这种情况下,有四个参数控制界面形状和位置:液态金属过热温度、模子表面温度、铸造速度以及有效热传导常数。在一般铸造情况下,液 Third, the impact of mold - adiabatic mat at the junction of the solidification process of the parameters of the formation of cold solidified shell solid-liquid interface and the mold insulation pad interaction results. If the interface is in direct contact with the thermal pad, it will form a cold compartment. Apply another method, if the interface with different insulation mat interaction, and only contact with the mold, it will not form a cold compartment. In this case, there are four parameters that control the shape and location of the interface: liquid metal overheat temperature, mold surface temperature, casting speed, and effective heat transfer constant. In the general case of casting, liquid
