Abstract:The generation and physicochemical properties of the dust from the dry de- dusting system (DDS dust) were discussed, and the practice of the process flow and practical application of dry de- dusting dust recovery from converter were introduced. The practices showed the XG slag- forming compounds, made mainly from DDS dust and from some manganese ore and quartz sand and special adhesives, can be used as converter slagging agent during the steelmaking. At the same time, the iron- carbon composite pellets, whose primary raw materials was also DDS dust, added some coking dust and special adhesives in manufacturing, was a fine auxiliary material for making steel. Both XC slag- forming compounds and iron- carbon composite pellets, mainly made from DDS dust, can bring plenty of economic and social and environmental benefits.
