手扶拖拉机的机引犁铧(图1)及旋耕刀(图2)原为65锰钢锻造,不但需要大量优质钢材,而且工艺复杂,成本也比较高。为了向贫下中农提供大量优质、价廉的农业机具,尽快实现伟大领袖毛主席关于农业机械化方面的宏伟规划,我们组成了以老工人为主体的厂校结合的三结合小组。这个小组遵照毛主席关于“我们必须打破常规,尽量采用先进技术”的教导,用球墨铸铁经过等温淬火制造这些零件。经过田间实验,效果良好,受到贫下中农的欢迎。
The tractor plowshare machine (Figure 1) and rotary trowel (Figure 2) was originally 65 manganese steel forging, not only need a large number of high-quality steel, and the process is complicated, the cost is relatively high. In order to provide the poor and poor peasants with a large quantity of high-quality and low-cost agricultural implements and realize the magnificent plan of Chairman Mao’s great mechanization in agriculture as soon as possible, we have formed a three-in-one small team combining factory with the old workers. The team follows Chairman Mao’s teachings on “We must break the routine and try to adopt advanced technology” to make these parts through austempering with ductile iron. After field experiments, the effect was good and welcomed by the poor middle peasants.
