苏联中央黑色冶金科学研究院研史了使用铁精矿粉制造部分由还原铁所组成的烧结团,并且在精矿粉的烧结过程中使用了固体还原剂粉及矿粉煤球,然后在1100～1300℃的温度下烧结。目的是为了得到足够强度的未烧结好的烧结球团并使铁的还原度达
The Soviet Union Central Black Metallurgical Research Institute of the history of the use of iron ore concentrate to make part of the reduction of the composition of the sintered iron, and the sintering process in the use of solid concentrate powder and briquettes briquette, and then 1100 ~ 1300 ℃ temperature sintering. The purpose is to obtain a sufficiently strong unsintered sintered pellet and to achieve a reduction of iron
