我车间革命职工,在毛主席革命路线指引下,在党支部的直接领导下,在有关单位帮助下,在用稀土镁球铁制造柴油机曲轴、凸轮轴和齿轮等零件的过程中,经过近二年的实践,不但初步掌握了以本溪铁为原材料的球铁热处理规律,而且试验了以地方生铁为原材料的球铁热处理(地方生铁的成分为硅2．8~3．5%,锰1．O~1．5%,磷0．1~0．25%)。下面介绍一下我们的试验情况和看法。 Under the guidance of Chairman Mao’s revolutionary line and under the direct leadership of the Party branch and with the help of the relevant units, during the process of manufacturing diesel engine crankshafts, camshafts and gears and other parts made of rare earth magnesium nodular iron, under the guidance of Chairman Mao’s revolutionary line, Years of practice, not only initially grasped the law of heat treatment of ductile iron with Benxi iron as raw material, but also tested the heat treatment of ductile iron with local pig iron as raw material (local pig iron composition is 2.8-3.5% of silicon and manganese 1). O ~ 1.5%, phosphorus 0.1 ~ 0.25%). Here’s about our trial and opinion.
