冲天炉生产铸态高韧性球铁件关键工艺控制

Control the Key of Technolog Steps to Produce Steading As-cast High Toughness Ductile Iron Casting in Cupola

通过对单一冲天炉熔炼条件下 ,稳定生产铸态高韧性球铁件的影响因素———温度、化学成份、球化和孕育处理工艺等进行深入的分析 。

On the basis of analyzing the effects of temperature,chemical composition and the process of nodulzaion and inoculation on the production of high toughness as-cast with only cupola, the contcolling measures of key technology steps are introduced in this paper.
