The flowaing behavior of steel melt during puring alloy steel tuby with centrifugal cast is investigated by analysis of force impose on steel melt and heat transmitting, and the gravity coefficient used in formula Of mold rotative speed is defined, 90~100 in early pouring period and 120 ~ 140 in solidifying.
本文通过对合金管在浇铸过程中钢水的受力分析及传热过程的分析，描述了高温钢水在型腔中的流动状况，确定出了离心铸造造型转速计算公式的重力系数在浇铸初期取值应为１２０～１４０、在凝固成型期的取值应为９０～１００。
