It is found from the result of calculation that when casting speed is constant, superheat and intensityofcooling have remarkable influence on the front edge of solidified shell.
根据模拟计算结果发现，在拉速一定的条件下，过热度和冷却强度对钢液的凝固前沿有着显著的影响。

In suspension pouring process the increase ofcoolingintensity during the solidification period will increase the tendency of volume solidification and decrease the solidification time.
悬浮浇注增加铸钢凝固期间的冷却强度，缩短凝固时间，增加体积凝固的倾向性。

Therefore, the coolingintensity and the casting speed can be rationally determined by the thickness of strand shell.
