| Abstract: | When molten general gray iron is poured into the mold coated by 1 # ferro silico rare earth and ferrosilicon coating,a compound cast iron material is obtained,there is nodular graphite in the surface layer,vermicular graphite in the transition layer,and flake graphite in the casting itself.The thickness of the surface nodularizing layer is over 2.5mm |
