高速线材轧制的稳定性分析

ROLLING STABLENESS ANALYSIS IN HIGH-SPEED WIRE LINE

在高速线材轧制过程中，轧件发生偏斜和扭转如果能够实现自动找正，则可保证顺利轧制。文中分析了高速线材生产中的椭圆——圆孔型系统的受力条件，说明了椭圆——双心圆孔型系统有更好的稳定性和找正作用，为高速线材孔型设计提供了稳定性依据。

Rolling process in high-speed wire line can be conducted successfully without skew and twist if the line can be regulated automatically. The mechanical conditions of oval-round passes in high-speed wire line are analysed. It is showed that the oval-round passes system has a better stableness and regulation function.
