前言攀枝花钢铁公司生产的钒钛炼钢生铁已在四川省机械工业铸造生产中得到广泛的应用。目前已用于耐磨铸铁、耐蚀铸铁、蠕虫状石墨铸铁、球墨铸铁等,在提高铸铁质量方面,起到了较好的作用。以贝氏体基体为主的钒钛球铁为例,用于汽车螺旋伞齿轮,具有较好的耐磨性和综合 Preface Panzhihua Iron and Steel Company production of vanadium titanium steel pig iron has been in Sichuan Province machinery industry casting production has been widely used. Has been used for wear-resistant cast iron, corrosion-resistant cast iron, worm-shaped graphite cast iron, ductile iron, cast iron in improving quality, played a good role. The bainitic matrix-based vanadium-titanium ductile iron, for example, spiral bevel gear, has good wear resistance and comprehensive
