泥型铸造在简单的、小型铸件上运用,可以提高劳动生产率,在经济上有着重大意义。这点已被愈来愈多的事实所证明,没有什么可怀疑的了。可是泥型能否应用在制造大型复杂,技术条件要求高的铸什上的看法还颇不一致,部分同志认为泥型透气性,退让性不好,修理的地方不牢靠,容易使铸什产生气眼、裂纹,塌砂等现象,因此不敢采用,我们认为这种顾虑是多余的。我车间曾用泥型铸出过重达14吨的烧碱锅,3吨重的碳酸机大飞轮,2.5吨重的气帽,800公斤重的碳酸机缸盖(φ1050×280)等。
Mud casting in simple, small castings on the use, can improve labor productivity, economically significant. This has been proved by more and more facts that there is no doubt about it. However, the mud type can be used in the manufacture of large and complex, high technical requirements of the casting of the view is quite inconsistent, some comrades that the muddy permeability, poor concession, repair the place is not reliable, easy to make cast even gas Eyes, cracks, sand collapse and other phenomena, so afraid to use, we think this concern is superfluous. My workshop used mud casting cast over 14 tons of caustic soda pot, 3 tons of carbonated machine flywheel, 2.5 tons of gas cap, 800 kg of carbonated machine cylinder head (φ1050 × 280) and so on.
