The invention discloses a preparation method of steel slag micro powder, and relates to the technical field of steel slag powder preparation. The preparation method comprises the following steps: putting the steel slag into an iron remover to remove iron; adding water, gypsum and an active exciting agent into the iron-removed steel slag; the active exciting agent is prepared from diethanolisopropanolamine, isopropanol, sodium fluosilicate, magnesium hydroxide and water; the dry autogenous mill is used for milling, the size of a grid plate is set according to the needed slag discharging granularity, and slag materials with the specified granularity are separated and discharged; iron removal is conducted on the steel slag micro powder obtained after dry grinding again; and after grinding is finished, qualified micro powder is separated out through powder selecting equipment and subpackaged, and the steel slag micro powder is obtained. The method has the advantages that the activity exciting agent is formed by the diethanolisopropanolamine, the isopropanol, the sodium fluosilicate, the magnesium hydroxide and the water according to a specific proportion, and the activity of the steel slag micro powder can be remarkably improved; when the steel slag micro powder is prepared, iron removal is more thorough, energy consumption is reduced, and cost is reduced.
本发明公开了一种钢渣微粉的制备方法，它涉及钢渣粉制备技术领域。制备包括以下步骤：将钢渣投入到除铁器中除铁；向除铁后的钢渣中加入水、石膏和活性激发剂；活性激发剂包括二乙醇单异丙醇胺、异丙醇、氟硅酸钠、氢氧化镁、水；通过干式自磨机进行磨粉，根据需要的排渣粒度设定格子板尺寸，使规定粒度的渣料分离排除；干磨后的钢渣微粉再次进行除铁；磨粉完毕后经过选粉设备分出合格的微粉进行分装，得到钢渣微粉。本发明的优点在于：通过二乙醇单异丙醇胺、异丙醇、氟硅酸钠、氢氧化镁、水按照特定配比形成活性激发剂，可显著提高钢渣微粉活性；钢渣微粉制备时，除铁更彻底，且降低能耗，减少成本。
