Inert steel slag micro-powder particles and preparation method thereof
The invention discloses inert steel slag micro-powder particles and a preparation method thereof. The inert steel slag micro-powder particles comprise the following raw materials in parts by weight: 1000 parts of steel slag particles, 15-25 parts of a sodium silicate binder and 0.4-0.8 parts of epoxy resin coating liquid. The raw materials for preparing the steel slag micropowder particles do not need to reach the specific surface area of 600-750 m < 2 >/kg, and a fine grinding procedure can be omitted in the production process link. The number of selectable equipment in the pre-grinding process is increased, and equipment investment and energy can be saved. The utilization mode of the steel slag micro-powder particles is changed from chemical component utilization to physical utilization, high-activity steel slag does not need to be specially selected, inert components of an RO phase do not need to be screened out, and utilization of low-activity steel slag is facilitated.
本发明公开了一种堕化钢渣微粉颗粒及其制备方法，包括以下重量份的原料：1000份钢渣颗粒、15‑25份硅酸钠粘结剂、0.4‑0.8份环氧树脂包膜液。本发明制备钢渣微粉颗粒的原料，不需要达到600‑750㎡/kg的比表面积，生产工艺环节可以省去细粉磨工序。预粉磨工序可选的设备增多，可节约设备投入和能耗。本发明的钢渣微粉颗粒的利用方式由化学成分利用转为物理利用，不需要专门选取高活性的钢渣和筛除RO相的惰性成分，便于低活性钢渣的利用。
