In order to systematically study the mineral phase composition and viscosity change law of hot metal pretreatment desulfurization slag, this paper summarizes and analyzes the desulfurization slag composition produced by different desulfurization agents. Phase diagram simulation was carried out using FactSage software to observe the phase composition of the desulfurization slag. Then the viscosity of the desulfurization slag was calculated in the conventional ironmaking temperature range, and the viscosity was observed with temperature. This study can enrich the theory of desulfurization slag and provide data reference for iron and steel enterprises to deal with the problem of hot metal pretreatment desulfurization residue and slag.
