导言钢铁生产中的脱硫问题,近百年来冶金工作者已给予足够的重视。自从大量生产球墨铸铁的近十余年来,国内外的许多铸造冶金工作者在铁水脱硫问题上作了许多有价值的实际工作和理论上的研究。铁水中的硫是重要的有害杂质。一般铸铁含量为0.08～0.1 Introduction Desulfurization in the production of steel has been given enough attention by metallurgical workers in the past century. Since the mass production of nodular cast iron for more than ten years, many domestic and foreign foundry metallurgists have made many valuable practical and theoretical studies on hot metal desulphurization. Hot metal in the sulfur is an important harmful impurities. The general cast iron content of 0.08 ~ 0.1
