大连钢厂与北京科技大学合作,采用了煤氧助熔炼钢新技术。冶炼时间每炉可缩短二十多分钟。为了满足这项新工艺的生产需要,大连钢厂投资120万元,建成一座年产6000吨粒度为二百目的煤粉磨制站。 这项工程1990年5月动工,10月建成投入试生产。试生产证明,该工程是目前冶金部特钢系列工厂采用该项新技术中规模最大、产量最高、质量最好的煤粉磨制车间。其中关键设备采用了上海冶金矿山机械厂生产的4R3Z16B型摆式磨粉
Dalian Steel and Beijing University of Science and Technology, the use of coal-oxygen steel smelting technology. Smelting time can be shortened more than twenty minutes per furnace. In order to meet the production needs of this new process, Dalian Steel invested 1.2 million yuan to build an annual output of 6,000 tons of pulverized coal grinding station with a particle size of 200 mesh. The project started in May 1990, completed in October put into trial production. Proof of production, the project is currently Metallurgical Special Steel series of plants using the new technology in the largest, highest yield, best quality pulverized coal grinding workshop. One of the key equipment used in the Shanghai Metallurgical Mining Machinery Factory 4R3Z16B type tilting mill
