我们地、县小厂所用的原生铁是含硅量较高的本溪生铁(硅3%),这给我们成批生产柴油机球铁铸件带来了很大困难。我们遵照毛主席关于“一个正确的认识,往往需要经过由物质到精神,由精神到物质,即由实践到认识,由认识到实践这样多次的反复,才能够完成”的教导,不断实践,摸索出利用含硅量较高的原生铁生产球铁曲轴、缸套等零件的经验,现介绍如下:
The primary iron used by small factories in our prefecture and county is Benxi pig iron (silicon 3%) with high silicon content, which brings great difficulties to our batch production of diesel iron ductile iron castings. In accordance with Chairman Mao’s teachings on “a correct understanding, we often have to go through materialism to spirituality, from spirituality to materialism, that is, from practice to understanding, and from the realization that so many repetitions of practice can be completed,” we continue to practice, Explore the use of high silicon content of primary iron production ductile iron crankshaft, cylinder liner and other parts of the experience are presented below:
