我们伟大领袖毛主席教导说:“在生产斗争和科学实验范围内,人类总是不断发展的,自然界也总是不断发展的,永远不会停止在一个水平上。因此,人类总得不断地总结经验,有所发现,有所发明,有所创造,有所前进。”以钢屑代替废钢,在我厂试验、生产已将近两年时间了。在这个过程中,我们通过三个不同试验阶段,前后82炉次、552根试棒、千余个铸件和熔化260余吨钢屑的生产实践,吸取了比较成功的经验和失败的教训。重点积累了一些关于以钢屑代替废钢,熔化可锻铸铁和灰口铁,在工艺操作方面的一些作法;并对以钢屑代替废
Our great leader, Chairman Mao, taught: “In the struggle for production and within the scope of scientific experiments, mankind always develops continuously, and the nature always develops continuously and never stops at a level. Therefore, mankind always has to sum up his experience Some discoveries, some inventions, have created, some progress. ”Steel scrap instead of scrap, in our factory test, production has been nearly two years. In this process, we learned the successful experiences and failed lessons through the production practice of three different pilot stages, front and rear 82 heats, 552 test rods, more than a thousand castings and more than 260 tons of steel scrap melting. Focus on the accumulation of some scrap instead of scrap steel, molten ductile iron and gray iron, some of the practices in the operation; and the replacement of scrap steel scrap
