我厂成批生产多用养路机(见照片一)。由于18CrMnTi原材料缺,机加工设备简陋,给生产带来很大困难,养路机所需各种齿轮全靠外单位支援。为了实现养路机械化,我们遵照伟大领袖毛主席关于“科学技术这仗一定要打,而且必须打好。不搞科学技术,生产力无法提高”的教导,在厂党委领导下,发扬“自力更生,奋发图强”精神,大搞科学试验。从一九七二年起,用稀土——镁钼球墨铸铁为原材料代替18CrMnTi合金钢生 I plant mass production of road maintenance machine (see photo one). As 18CrMnTi lack of raw materials, machining equipment primitive, to bring great difficulties in production, maintenance of all kinds of gear required by road units outside the unit support. In order to realize the mechanization of road maintenance, following the guidance of Chairman Mao, the great leader, on the principle of “science and technology must fight this battle and must lay a good foundation. Without science and technology, productivity can not be improved.” Under the leadership of the factory party committees and committees, we will promote "self-reliance, Spirit, make scientific experiments. Since 1972, with rare earth - magnesium molybdenum nodular cast iron as raw material instead of 18CrMnTi alloy steel students
