在铸造铸铁零件时,采用冷风焦炭炼铁炉,其炉料中可用炼钢生铁代替铸造生铁。对这种铸铁的机械性能和铸造性能研究表明:铸铁的珠光体组织中含有细小弥散的石墨,金属的δ_b和δN提高5-10%;形成缩孔、缩松的倾向减少约30%;在浇注温度不变的情况下流动性可增加1～15%;白口趋势基本上不变, In the casting of cast iron parts, the use of cold wind coke iron furnace, the charge can be used in steelmaking pig iron instead of casting pig iron. The research on the mechanical properties and casting properties of the cast iron shows that the pearlite of cast iron contains fine and dispersed graphite, the δδ and δN of the metal increase by 5-10%, the shrinkage and the tendency of shrinkage decrease about 30% Pouring temperature unchanged in the case of liquidity can increase 1 ~ 15%; white mouth trend is basically unchanged,
