Magnesium powder desulfurization slag iron treatment method

The invention relates to a magnesium powder desulfurization slag iron treatment method. The method comprises the steps of desulfurization slag collection, steel ladle top slag collection, different slag mixing, cooling, recycling and the like. The magnesium powder desulfurization slag iron treatment method provided by the invention has the following advantages that the sulfur element in the slag iron mixture enters the top slag instead of molten steel, so that the desulfurization pressure caused by slag iron recovery to a converter process and a refining process is reduced; the size of the slag-iron mixture is relatively small, so that the damage to the torpedo ladle in the slag-iron adding process is reduced; after the high-alkalinity slag-iron mixture is added, the alkalinity of molten iron top slag is improved, and the consumption of lime and magnesium powder can be reduced. 本发明涉及一种镁粉脱硫渣铁处理方法，包括：收集脱硫渣、收集钢包顶渣、不同渣混和、冷却和再利用等步骤。本发明提供的镁粉脱硫渣铁处理方法，具有如下优点：渣铁混合物中硫元素进入到顶渣中，而非钢水中，这将减轻渣铁回收给转炉工艺和精炼工艺带来的脱硫压力；渣铁混合物尺寸相对小，
