In continuous casting course, the liquid core length is a very important parameter, it reflects the cooling condition of casting and the appropriate degree of pulling speed.
在连铸生产工艺中，连铸坯的液芯长度是连铸生产中一个非常重要的参数，它直接反映了铸坯冷却的状况和拉速的合理程度。
3 get the core length, core assembly size is determined according to the structure size of the mold core seat;
得到模芯的长度后，根据模芯座的结构尺寸确定模芯装配尺寸；
Increasing core length properly can raise motor efficiency and power factor, but it will reduce locked-rotor torque ratio and breakdown torque ratio.
适当增加铁心长度可以有效提高电机效率和功率因数，但会导致启动转矩倍数和最大转矩倍数减小。
