从理论上推导出了铸铁螺旋孔型斜轧过程中连接颈处的热效应计算公式 ,为分析材料在轧制时的强度奠定了一定的理论基础
The calculation formula of the thermal effect on the connecting neck during the process of skewing rolling of the cast iron was deduced theoretically, which laid a theoretical foundation for the analysis of the strength of the material during rolling
