摘　　要：某轧钢厂将四辊中厚板轧机,撤去两个支承辊,改造成以轧制25#角钢、U型钢、球扁钢和矿工钢等大型材为主的二辊开坯机。工作辊最小直径1150mm,辊身长2600mm,辊身开5个轧槽。本文以轧制25#角钢(材质Q460c)为例,对初轧机进行孔型设计、轧辊强度校核和挠度的计算,以及应用有限元软件ANSYS/LS-DYNA模拟轧制力曲线。In one mill-fig：tory,two bearing roller will be removed on a four-roller plate mill,which is transformed to two-roller mill that mainly roll 25# angle iron,U steel,ball-fiat steel and Steel Miners. Minimum diameter of working-roller is 1150mm,roller-body＇s length is 2600ram,there are five pass troughes in roller body. It example on milling 25# angle iron,desigaing pass for initial mill,roller Strength Verificated,ealculate deflection as well as simulate rolling force curve with FEM soft of ANSYS/ LS-DYNA.
