摘要

研究了高硫高强铸铁金属型铸造时，硫对白口化的作用和Ｓ／Ｓｉ值对退火时间及石墨形态的影响。结果表明合适的硅硫含量各为Ｓｉ＝２．０％～２．５％，Ｓ＝０．２％～０．４％，Ｓ／Ｓｉ＞０．１。指出了Ｓ／Ｍｎ值对石墨形态的重要作用，论述了硫的作用机理

Abstract

Effect of sulfur on chilling tendency and S/Si ratio on annealing time and graphite morphology for high duty cast iron with high sulfur content in metallic mould was studied. Experimental results indicated that the appropriate sulfur silicon contents were S=0.2%￣0.4%

Si=2.0%￣2.5%

S/Si>0.1. It was suggested that S/Mn played important role for graphite morphology. The mechanism of sulfur effect was discussed.
