介绍了土拉切尔梅特RPA公司2号高炉（1033 m3）100%用氧和喷吹热还原性气体的炼铁新工艺。该工艺包括高炉炉顶煤气净化、压缩、通过化学吸收去除二氧化碳、在热风炉蓄热室中预热煤气、并通过风口代替热风吹入炉内。这种热还原气体（HRG）的使用伴随着通过每个喷嘴的氧气注入。在1985 ~ 1990年期间，共进行了13次试验，生产了25万t铁水。在一个特定的试验中，用251 m3/thm的氧气实现了367 kg/thm的焦炭速率，同时生产1700 thm/天的2.2%硅铁。
Presented new ironmaking process on the basis of 100% usage of oxygen and hot reducing gas injection into the No. 2 blast furnace (1033 m3) at RPA Toulachermet. The process involves blast furnace top gas cleaning, compressing, removal carbon dioxide through chemical absorption, preheating the gas in the hot blast stove regenerators, and blowing into the furnace through tuyeres in place of the hot blast. This use of hot reducing gas (HRG) is accompanied by oxygen injection through each tuyere. There have been 13 trials of this technique in the period 1985-90 producing 250000 t of hot metal. In one particular trial the coke rate of 367 kg/thm was achieved with 251 m3/thm of oxygen while producing 1700 thm/day of 2.2% silicon iron.
