影响球墨铸铁冲击性能的因素有C、Si、P等主要元素,冷却速度,Ti、Al、As、Sb、Bi、Sn、Pb、V、Cr、Mo、Mn等微量元素的影响,还有生铁原材料的影响。生铁在铁矿石熔炼过程中,混入各种微量元素,其生铁的特性也各异。原材料中微量元素对冲击性能的影响,过去采用 The impact of ductile iron impact performance factors such as C, Si, P and other major elements, cooling rate, Ti, Al, As, Sb, Bi, Sn, Pb, V, Cr, Mo, Mn and other trace elements, as well as pig iron The impact of raw materials. Pig iron in the iron ore melting process, mixed with various trace elements, the characteristics of pig iron are also different. The impact of trace elements on the impact properties of raw materials used in the past
