我厂承担的球磨破碎两类产品中,高锰钢件(衬板、格子板、齿板)约占铸钢件重量的30％。随着生产的发展,对这两类产品要求的数量越来越多,质量越来越高。我厂广大铸造工人和干部,在批林批孔运动的推动下,对高锰钢铸件生产的工艺流程进行大胆的革新,将原来浇涛后的冷却、打箱、消砂、淬火等多工序合成一道工序——水爆淬火。经过2个月的试验,基本是成功的,到1974年10月为止,已试生产100多吨,提高综合生产效率2～3倍,为国家节约资金一万余元。现将试验情况介绍如下: 高锰钢铸态组织绝大多数是由奥氏体和碳化物组成,由于碳化物的存在,降低了钢的冲
I plant bear the ball mill broken two types of products, high manganese steel parts (liner, lattice board, tooth plate) about 30% of the weight of steel castings. With the development of production, the demand for these two types of products is more and more and the quality is higher and higher. I plant a majority of casting workers and cadres, approved in the forest approved bored hole campaign, the high manganese steel casting process of the bold innovation, the original pouring Tao after the cooling, boxing, aseptic, quenching and other processes Synthesis of a process - water quenching. After two months of testing, the basic success was that up to October 1974, more than 100 tons of finished products had been tested and the comprehensive production efficiency was increased by 2 to 3 times, saving more than 10,000 yuan for the country. Now the test conditions are as follows: The vast majority of high manganese steel as-cast austenite and carbide composition, due to the presence of carbide, reducing the red steel
