`Lining Pains and Lance Strains-A Case Study to Competing Productivity

Atul Vats, Priyavrat Thareja


A relation between sinter usages in burden and productivity are well established. Now a day, almost all blast furnace usages a sinter in its burden charge. The percentage of sinter in blast furnace is depending upon the availability of fines & sinter machine. But some time, due to non–availability of fine or sinter machines, or both, only calibrated iron ore lump are used as a source of iron in charge burden. The behavior and characteristics of blast furnace changed when 100% iron ore lump are charged as compared to iron ore lump and sinter in burden. The behavior of 100% iron ore lump (CLO) charged in furnace is focused in this paper.
