Optimization of Industrial Test for Desulfurization Effect of Molten Iron
In order to improve the desulfurization process of molten iron and enhance its desulfurization capacity,a KR method desulfurization water model test is proposed.By discussing the experimental geometry and kinetics,the experimental principle is discussed,and organic glass is used instead of the molten iron tank reactor.A water model test device is designed to analyze the effects of rotational speed,insertion depth,loading depth,and agitator on the desulfurization effect in molten iron desulfurization,and experimental analysis is conducted.The results showed that the optimal desulfurization effect was achieved under the conditions of a speed of 160 r/min,a loading depth of 450 mm for the molten iron tank,a diameter ratio of 0.38 for the agitator tank,and an insertion depth of 213 mm.The optimized agitator achieved efficient operation,which has guiding significance for the transformation of the molten iron desulfurization process.
