对由电解铁加电极石墨熔得的含碳4.3％的Fe-C合金,在高频熔炼的条件下,用纯锑作为加入元素,含铈45％的混合稀土合金作抑制剂,含镁21.4％的合金作球化剂进行了试验。加锑量为0.05、0.1、0.4％,加铈量为0.1、0.2、0.3、0.4％。研究表明,对于球化处理后的试样,如只加铈而不加锑,则随着加铈量的增加,将析出网状石墨,加锑后加入适量的铈,可抑制不规则形状石墨的析出;试样的残留含锑量,随加铈
For carbon-containing 4.3% Fe-C alloy melted by electrolytic iron plus electrode graphite, pure antimony was added as an added element and mixed rare earth alloy containing 45% cerium as an inhibitor under high-frequency melting conditions, and magnesium 21.4 % Of the alloy as a balling agent were tested. Add antimony content of 0.05,0.1,0.4%, plus cerium content of 0.1,0.2,0.3,0.4%. The results show that, for the spheroidized sample, if only cerium is added without antimony, with the increase of cerium content, the reticular graphite will be precipitated and an appropriate amount of cerium will be added after the antimony is added to inhibit irregular shaped graphite Of the precipitation; residual antimony content of the sample, with the addition of cerium
