Presented new ironmaking process on the basis of I OO o/.usage of oxygen and hot reducing gas injection into the No 2 blast furnace (1 033m*) 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 hdt reducing gas (HRG) is accompaniedby oxygen injection through each tuyere.There have been 13 trials of this technique in the period 1 985-90 producing 250000t of hot metal.In one particular trial the coke rate of 367 kg/thm was achieved with 251 m'/thm of oxygen while producing 1 700thm/dayof 2.2010 silicon iron.
