Abstract：Effect of flux particle size on hot metal desulphurization was investigated by hot metal desulphurization experiment using desulphurization flux with various particle sizes. The results indicate that the desulphurization ratio and apparent desulphurization rate constant increases with particle size decrease. The microstructure of desulphurization slag particle was studied by scanning electron microscope. The outer shell is desulphurization production CaS with thickness about 10-50μm, the intermediate layer is mainly 2CaO·SiO2, and the core is CaO. The utilization ratio of lime particle increased rapidly with the decrease of particle size. It is suggested that the desulphurization flux particle size should be 0.5-1.5mm to get better desulphurization effect and higher utilization ratio of the flux.
