日本一家钢铁公司发明了一种铁水脱硫的简易工艺。该工艺是在高炉出铁场主沟出渣器的下部，设置一个铁水脱硫反应槽，向反应槽喷火脱硫剂进行连续脱硫；脱硫剂在喷枪下流动反应生成的脱硫渣，用扒渣装置连续进行去除。这种脱硫工艺能够利用铁水从高炉放出后的最高温度，以满足 A steel company in Japan invented a simple process for hot metal desulphurization. The process comprises the following steps of: setting a molten iron desulfurization reaction tank at a lower part of a slag discharger in a blast furnace tundish main groove; continuously desulfurizing the desulfurization agent by spraying the desulfurization agent into the reaction tank; desulfurization slag produced by flowing reaction of the desulfurization agent under the spray gun, Continuous removal. This desulphurization process can utilize the maximum temperature after hot metal is released from the blast furnace to meet
