转炉顶底复合吹炼技术是本世纪七十年代中后期发展起来的转炉炼钢新技术。我厂三座50吨转炉从1984年3月起使用简易供气装置已初步实现了复合吹炼。但由于该系统装备水平低,不能实现吹炼过程中的供气调节,因此不能完全满足炼钢工艺要求,和国外先进复吹供气系统相比,差距甚大。为此,1986年在原简单供气系统上进行了技术和设备上的改造。我们与武汉钢铁设计研究院、公司技术部、计控厂、钢研所等单位一起研
BOF blowing technology is the top half of the century developed in the mid-late converter steelmaking new technology. I plant three 50-ton converter from March 1984 since the use of simple gas supply has been initially achieved composite blowing. However, due to the low level of equipment of the system, the air supply regulation in the blowing process can not be realized and therefore the steelmaking process can not be fully met. Compared with the advanced air blowing system in foreign countries, the difference is very large. To this end, in 1986 the original simple gas supply system on the technical and equipment transformation. We and Wuhan Iron and Steel Design Institute, the company’s technology department, control plant, steel research institutes and other units together
