Desulfurizer is the desulfurization dregs serious developed by our company for adapting out furnace refining, which not need extra expenses of investing equipment when using it. Used as out furnace desulfurization in tapping courses, it has the advantages of easy use, economic, effective and high desulfurization rate,  which may be widely used before smelt-making techniques, and the desulfurization rate may be as high as 40~80%. The product has good desulfurization effect and has Aevident effect of reducing the cost of steel-making.
