摘要
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。
The paper firstly deals with a new type of bainite ductile iron production processing different from austempering, and the bainite ductile iron bar hasbeen produced by horizontal continuous casting. Secondly, in order to provide the base of plastic deformation, the resistance to deformation of this material has been studied. Research on the technical parameters of rolling from thick bar to thin bar and from bar to plate has also been made. Lastly, ??= 35, 40, 60mm grinding balls which are of excellent properties have been successfully produced with skew rolling mill.
