| Abstract: | This paper deals with the using of sythetic iron with high manganese and high residual elements in pouring centrifuglly casted ductile iron pipe in resin sand coated metal mould.Studies were made on the influence of in-mould inoculation, instant inoculation and bismuth inoculation on the plasticity of cast ductile iron pipe. Meanwhile,a rule is also studied in this paper to examine how manganese, silicon and carbon equivalent as well as thickness of precoated sand affect the plasticity of cast ductile iron pipe. |
