METHOD FOR MANUFACTURING SINTERED ORE USING FINELY CALCINED DOLOMITE |
摘要 |
PURPOSE: A method for manufacturing sintered ore using finely calcined dolomite is provided to improve reduction differentiation intensity of the sintered ore by using as a sintering raw material the calcined dolomite having a low softening temperature as a MgO adjusting agent in sintering raw materials preventing lowering of slag fluidity in a blast furnace. CONSTITUTION: In a method for manufacturing sintered ore comprising the processes of obtaining granulated particles by mixing sintering raw materials comprising a MgO adjusting agent with a sintering fuel in a mixer, and charging the obtained granulated particles into a sintering machine, the method for manufacturing the sintered ore further comprises the process of adding finely calcined dolomite to the sintering raw materials so that 0.5 to 1.5 wt.% of finely calcined dolomite having a size of 5 mm or less as a MgO adjusting agent is blended with the sintering raw materials for 100 wt.% of the sintering raw materials.
