Method for preparing micro powder by smelting and tempering steel slag
The invention relates to the technical field of comprehensive utilization of metallurgical solid wastes, and particularly discloses a method for preparing micro powder by smelting and tempering steel slag, which comprises the following steps: A01, after fully stirring and mixing steel slag and acidic oxide, adding a reducing agent, and stirring and mixing to obtain a steel slag mixture; a02, the steel slag mixture prepared in the step A01 is added into a smelting furnace to be smelted till the steel slag mixture becomes liquid and bubbles are generated on the surface, then a proper amount of a hardening and tempering agent is added for mixing and stirring, and heating continues till the solution is layered; a03, the upper layer of the separated and layered solution is subjected to quick freezing treatment, the temperature is reduced to 50 DEG C or below within 15 s through quick freezing treatment, and the lower layer is poured into a container to be naturally cooled; a04, the upper layer obtained after quick freezing treatment is quenched and tempered slag, the quenched and tempered slag is dried, ground and screened, and micro powder is obtained.The method solves the problem that the traditional steel slag utilization rate is low.
本发明涉及冶金固体废弃物综合利用技术领域，具体公开了一种利用钢渣冶炼调质制备微粉的方法，包括以下步骤：A01：将钢渣与酸性氧化物充分搅拌混合后，加入还原剂后搅拌混合后制得钢渣混合料；A02：将步骤A01制得的钢渣混合料加入熔炼炉中冶炼至钢渣混合料变成液体且表面产生气泡，然后加入适当调质剂混合搅拌，继续加热至溶液分层；A03：分离分层后的溶液，上层急冻处理，急冻处理在15s内将温度下降到50°以下，下层倒入容器自然冷却；A04：急冻处理后的上层为调质渣，调质渣经烘干、干燥、研磨和筛分后，获得微粉，本方法解决了传统的钢渣利用率低的问题。
