我们铸铁组遵照毛主席关于“农业的根本出路在于机械化”的教导,坚持研究工作为工农兵服务的方向,到拖拉机站和农机制造工厂进行了调查研究。贫下中农反映,拖拉机缺少“鞋”不能下地,因为链轨板是用高锰钢做的,制造困难,供应紧张。因此,需要研究新的制造链轨板的材料。 Our cast iron group, following Chairman Mao’s teachings on “fundamental road to mechanization in agriculture,” insisted on the direction of research work for the workers, peasants and soldiers, carried out investigations and studies on tractor stations and agricultural machinery manufacturing plants. Poor middle peasants reflect the lack of tractors “shoes” can not go to the ground, because the chain rail plate is made of high manganese steel, manufacturing difficulties, tight supply. Therefore, there is a need to study new materials for manufacturing the rail plate.
