The invention discloses an efficient environment-friendly KR desulfurizing agent and a preparation method thereof. The efficient environment-friendly KR desulfurizing agent comprises the following rawmaterials of, in parts by weight, 5-15 parts of aluminum-magnesium-iron alloy, 74-84 parts of active lime powder, 1-6 parts of limestone powder, 3-6 parts of reduced metal calcium slag and 1-3 partsof powdery sodium silicate. Compared with the prior art, the efficient environment-friendly KR desulfurizing agent and the preparation method thereof have the beneficial effects that the desulfurizingagent has no smoke dust, does not pollute the environment and has higher sulfur capacity when in use, and the components in the desulfurizing agent can ensure stronger reducing atmosphere, so that the desulfuration is more thorough, and the desulfurizing agent is beneficial to the low-sulfur smelting of high-quality steel. 一种高效环保型KR脱硫剂及其制备方法，包括如下重量份数的原料：铝镁铁合金5份～15份、活性石灰粉74份～84份、石灰石粉1份～6份、还原金属钙渣3份～6份、粉状硅酸钠1份～3份。与现有的技术相比，本发明
