Abstract:In the current study,ladle slag reducer was made using aluminum dross that contained a low content of metallic aluminum and high percentage of AlN.Laboratory experiments were performed in MgO crucibles under 1600℃ with a 1∶10 dross-steel ratio and a 4∶6∶1 dross-lime-fluorite, the samples were cooled by nature convection after 90 min heat preservation.The results indicate that both AlN and metallic aluminum in the dross could work as reducer to remove the oxygen in BOF slags carried on.Using this kind of aluminum dross,the w((FetO)) in BOF slag could be decreased from 31.2% to 3.2%,w([O]) in the steel can be lowered from 480×10-6 and 17×10-6,and w([S]) in the steel is lowered 190×10-6 and 75×10-6.However,the w([N]) in the steel is increased from 66×10-6 to 129×10-6.
