摘　　要：使用ANSYS有限元软件建立模型,分析定宽机使用平锤头和孔型锤头时板坯的变形规律。结果表明,孔型锤头有助于提高板坯在减宽过程中材料变形的均匀性,减轻了金属材料在板坯两端的堆积,有助于改善热轧板边部细线缺陷。ANSYS finite element software was used to establish the model and analyze the deformation law of slab when flat hammer head and hole hammer head were used. The results show that the pass hammer head is helpful to improve the uniformity of material deformation during the slab width reduction. It can reduce the accumulation of metal materials at both ends of the slab and help to improve the thin line defect at the edge of hot rolled sheet.
