steel industry. However, calcined lime has an additional advantage in the sinter process like improvement in mean size, tumbler index and reducibility index. The higher size flux generates free calcined lime faces in the sinter. As it is known that calcined lime is very much hygroscopic, the sinter gets decrepitated.

Abstract. A new process called 'NO x reduction by coupling combustion with recycling flue gas (RCCRF)' was proposed to decrease NO x emission during the iron ore sintering process. The simulation test of NO x reduction was performed over sintered ore and in the process of coke combustion. Experimentally, NO x reduction was also carried out by sintering pot test.

iron ores. In addition, with continuous exhaustion of iron ore resources, highquality iron ores become increasingly scarce in China. Therefore, to utilize these tinbearing iron concentrate is very important to save iron and tin resources. It is known that iron ore sintering is one of the most important processes in the steel manufacturing industry.
