利用攀枝花钒钛生铁经稀土变质处理后用于制造机床导轨、滑块及汽车后桥齿轮……等零件,已被多年的实践证明是可行的。在这基础上,能否进一步扩大材料的使用范围,充分利用我省的丰富资源,寻求一种既耐磨又耐蚀的新材料,便成为我们的研究课题。通过两年多的研究和实践,在钒钛生铁中加入4～6%的铝,制成稀土钒钛铝硅铸铁(以下简称铝铸铁)用于制造碳酸氢铵成球机的轧辊及机械密封环零件,它的耐蚀性能和耐磨指标均可同原使用材料YGB、YG6硬质合金和
The use of vanadium and titanium pig iron in Panzhihua after rare earth modification for the manufacture of machine tool rails, sliders and rear axle gear ... ... and other parts, has been proven for many years is feasible. On this basis, we can further expand the scope of the use of materials, make full use of the rich resources of our province to find a new material that is both wear and corrosion resistant, it has become our research topic. Through more than two years of research and practice, 4 ~ 6% of aluminum is added to vanadium-titanium pig iron to make roll and mechanical seal of rare earth vanadium titanium aluminum silicon cast iron (hereinafter referred to as aluminum cast iron) for making ammonium bicarbonate into ball machine Ring parts, its corrosion resistance and wear resistance indicators can be used with the original material YGB, YG6 cemented carbide and
