I have measured the temperature of roasting kiln and the time when the iron ore pass through the kiln and have found out following proper conditions. (1) The suitable amount of coke breeze are 30∿40kg/t of roasting ore and the proper roasting temperature is from 800℃ to 900℃. (2) The rate of desulphurization is 50% (3) The proper size of iron ore is from 30mm to 50mm and the fine ore damage the draft of kiln and make the roasting operation impossible.
