A PROCESS FOR SINTERING USING STEEL MAKING SLAG AS HEARTH LAYER IN SINTER PLANT FOR INSULATION

摘要

A process of enhancing sinter productivity by using steel making slag as insulation in hearth layer in sinter plant is disclosed. More particularly, the present invention is directed to a process for sintering whereby sinter output and productivity of sinter plant is enhanced by introducing steel making slag in the size range of 12-20mm substituting part of conventional good quality sinter products 10-20mm size for providing the hearth layer of desired thickness over the pallet as insulation layer to protect grate bars of pallet boxes and resultantly increase the sinter output by about 1.75% over conventional process of sinter making. Importantly, the process favour gainful recycling of steel slag mitigating disposal problem, while recovering valuable iron content of steel slag and also ensuring longer pallet life. (Figure 2).
