遵照伟大领袖毛主席关于“人类总得不断地总结经验,有所发现,有所发明,有所创造,有所前进”的伟大教导,我车间在成功地采用油炉熔炼铝合金后,又实现了用油炉熔炼稀土—硅铁—镁中间合金,为国家节省了大量的焦炭。生产稀土—镁球墨铸铁时,稀土—硅铁—镁中间合金的加入量为1.6～1.7％。 Following the great teachings of Chairman Mao, the great leader, on the principle of “human beings always summarize experiences, discoveries, inventions, innovations, and advances,” my workshop succeeded in using oil furnace smelting aluminum alloy Rare earth with oil furnace smelting - ferrosilicon - magnesium master alloy, save a lot of coke for the country. When producing rare earth-magnesium nodular cast iron, the amount of rare earth-ferrosilicon-magnesium master alloy added is 1.6-1.7%.
