Abstract：The desulfurization slag in the pretreatment of hot metal normally has high content of iron and sulfur，which has the potential to be recycled. Recently，numerous large steel corporations are endeavoring to the studies of the recycle of desulfurized slags. The current study introduced the desulfurization slag recycle experiments conducted in Qian-steel，and analyzed the production data. The experimental results show that the increase of sulfur content in the 8 t slag reaches 0.013 6%，which results in high sulfur content in the LD furnace. The LF refining process is essential to desulfurize deeply，which will raise the electricity consumption and extend the production cycle. In summary，the recycle of desulfurization slag is able to improve the metal yield，thus reduces the steel-making cost and increases the profits.
