150mm×150mm连铸方坯生产小型材的粗轧开坯孔型设计

The Blooming Pass Design For Producing Small-Sized Billets by using 150mm×150mm Continously Casting Billets

15 0mm× 15 0mm连铸方坯生产小型材的粗轧开坯孔型系统的设计获得成功 ,并应用于生产实际满足了生产要求。

This paper mainly discusses how to make use of the character of flexibility of box-pass matching to design a new box-pass which can substitute for the old box-pass using 130mm×130mm square billets.Applying to 150mm×150mm continuously-casting billets,the new passes are promptly used in the bar rolling.
