Abstract:In order to promote sensible heat recovery of smelting slag, reduce energy consumption in iron and steel smelting process, and improve utilization rate and economy of smelting slag, by analyzing the difficulties in the treatment and utilization of the molten slag in steel mills, a dry granulation method for molten slag based on the modification and foaming treatment is proposed, and the thermal conductivity as well as granulation of slag are improved by introducing metallic iron and foaming, which provides a way to solve the problems faced by the dry granulation and slag utilization. At last, some suggestions on the future research direction of dry granulation are given.
