研究新型贝氏体球墨铸铁的制取工艺，并在水平连续铸造设备上拉制成棒材。探讨该材料的变形抗力以及棒材轧制工艺参数，为该材料的塑性变形提供了依据。在斜轧机上成功地轧出了性能很好，直径分别为３５，４０， ６０ ｍｍ的磨球。 Research new bainitic cast iron ductile iron production process, and in the horizontal continuous casting equipment made of rods. The deformation resistance of the material and the bar rolling process parameters are discussed, which provide the basis for the plastic deformation of the material. The mill was successfully rolled out on a cross-rolling mill with 35, 40, 60 mm diameters.
