Production of Reducing Sinter Alkalinity and Magnesium-aluminum Ratio of Blast Furnace in Qingdao Specialsteel
In view of the problem of the high ratio of sinter alkalinity and magnesium-aluminum,Qingdao special iron and steel sintering starts from the reduction of alkalinity and magnesium oxide in sinter.After the implementation,the quality of sinter was reduced to a degree.On the premise of ensuring the blast furnace condition,the MgO of sinter decreased by 0.2%,R2 decreased by 0.07,the MgO/Al2O3 was reduced by 0.05-0.09,the cost of molten iron was reduced by 2.13 Yuan/ton,and the annual cost of molten iron was reduced by 10.65 million Yuan.
