摘要：

Presented new ironmaking process on the basis of 1 00 % usage of oxygen and hot reducing gas injection into the No 2 blast furnace (1 033 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 250 000 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 1 700thm/day of 2.2% silicon iron.
