| Abstract: | This paper described the foundry technology of horizontal pouring and solidifying to produce large hollow ductile iron crankshaft cast in sand coated iron mould. On the base of the proportional solidification principle, the problem of casting's shrinkage porosity was solved and fine casting with as cast pearlitic structure was obtained. |
