我矿是一个机械化程度较高的大型露天磷矿,由于原有设计不配套,铸钢配件本矿不能生产,全部依靠外援。随着生产的不断发展,大家感到机修车间必须生产铸钢配件。最近几年来,曾提出多种铸钢生产方案,都因为投资大,占地宽,见效慢,一直未能实现。因而,我矿铸钢配件的生产迟迟得不到解决。昆明工学院在开门办科研中,于1973年试验成功双自耗极有衬炉电渣熔炼新工艺,并开始在云南省推广使用。我矿在昆明工学院的协
Mine is a large mechanized high open pit phosphate rock, due to the original design is not complete, the castings can not produce the mine, all rely on foreign aid. With the continuous development of production, we feel that the machine shop must produce cast steel fittings. In recent years, a variety of steel production programs have been proposed because of the large investment, wide area and slow success, which have not been realized. As a result, the production of mine steel castings has not been solved. Kunming Institute of Technology in the open to do scientific research, in 1973 the successful trial of dual-depletion of a very new furnace slag electroslag smelting technology and began to promote the use of Yunnan Province. I mine in Kunming Institute of Technology Association
