研究了含锑复合孕育剂对可锻铸铁白口倾向,退火石墨化速度,石墨的数量,大小及形状,基体组织以及机械性能的影响.试验结果表明:采用锑、铋这两个促进铸态白口倾向的元素和铝、钡硅铁这二种促进退火石墨化的组无复合孕育处理可锻铸铁,可以获得满意的综合效果. The effects of antimony-containing inoculant on the whiteness of malleable cast iron, the graphitization rate of annealing, the amount, size and shape of graphite, matrix structure and mechanical properties were studied.The experimental results show that the antimony-bismuth compound The tendency of the elements and aluminum, barium ferrosilicon annealing and graphitization of these two groups without compound inoculation malleable iron treatment can be satisfied with the comprehensive effect.
