So less gas is. given off in the mould than with rimming steel, but enough bubbles form at the top of the ingot to counteract most of the shrinkage.

所以，在钢锭模内析出的气体没有沸腾钢多，但又在钢锭头产形成足够的气泡抵消大部分钢的收缩。

The invention provides the ingot mould and the casting method which solve a problem that crackles are produced during a process of casting the round steel ingots.

本发明提供了一种解决圆钢锭浇铸过程中产生裂纹的钢锭模及其浇铸方法。
