摘　　要：研究了低铬铁水脱磷粉剂的熔化性能,通过二次回归正交实验,考察了BaCO3等其它组成对该渣系熔点及熔速的影响。研究结果表明:21.5%CaO-15%BaCO3-40%Fe2O3-12.5%CaF2-5%Cr2O3-6%镁铬砖熔剂熔点较低,为1170℃;熔化速度较快,为3min,能快速成渣且温降较低。The present paper mainly studied the melting performance of the dephosphorizing reagent for low chromium-containing hot metal as well as the influence of BaCO3 and the other constituents on the melting point and speed of the slag by way of the quadratic orthogonal regressive experiments. Experimental results show that the melting point of the flux of the Magnesium chromium brick composed mainly of 21.5 % CaO- 15%BaCO3-40%Fe2O3-12. 5%CaF2-5 %Cr2O3-6% is lower （1 170 ℃）, and its melting time faster （3mins）, so the flux can satisfy the demand of dephosphorization of low chromium-containing hot metal.
