本专题为南钢15t复吹转炉新工艺的一部分,本专题1986年首先应用南钢生铁,在100kg复吹感应炉中进行热模拟试验,得到了复吹条件下的元素氧化规律,在此基础上,在南钢15t复吹转炉中使用吊桶取样装置,于3次工业试验中取出45炉钢渣过程样,研究了215炉冶炼过程,得到了使用环缝式及小集管式供气制度下的元素氧化规律及造渣规律,并提出了合理的工艺制度。
This project is part of the new technology of Nantong 15t composite blowing converter. In this project, the steel was first applied in 1986 in a 100kg composite blowing induction furnace, and the elemental oxidation under complex blowing condition was obtained. Based on this, , The use of bucket sampling device in the 15t BOF converter of Nangang Steel removed 45 furnace slag process samples from 3 industrial experiments and studied the 215 furnace smelting process and obtained the results of using gasholding and small header gas supply system Elemental oxidation rules and slagging rules, and put forward a reasonable process system.
