摘要：
Experts explain the control of hot metal sulfur coming in high levels from the blast furnace during steelmaking by the combined technology of hot metal and steel desulfurization. The benefit sharing between the BE and the BOF shops is recognized and the requirements of high-quality steel products on sulfur control are reviewed. Extensive examinations reveal that all steel types are on a different sulfur level and require special treatments according to their specifications. The total De-S required is split between the different product stages during liquid steel production. The main goal is to guarantee that the desulfurization reaction must be completely stopped after release of the liquid steel to the caster.
