型钢万能连轧机组采用混合孔型轧制槽钢是一种新工艺,通过使用H型钢万能轧机生产线对18~32号等多个槽钢产品的开发和生产,得出了型钢万能连轧机组采用混合孔型轧制槽钢的特点和规律。主要介绍在H型钢万能连轧生产线上应用此万能法轧制槽钢的工艺方法及孔型系统,并与传统两辊孔型法进行了比较,通过实践证明此工艺值得在相似生产线上推广。 It is a new technology to adopt the mixed hole type rolling channel steel in the universal rolling mill of the type steel. By using the production line of the H-beam universal mill for the development and production of multiple channel products such as No. 18 to No. 32, Adopts the characteristics and rules of mixed pass rolling channel. This paper mainly introduces the process and hole system of this universal method for rolling channel in the H-beam universal continuous rolling production line. Compared with the traditional two-pass method, it is proved that this process is worth promoting in similar production line.
