Reduction tempering agent and application thereof in treating steel slag
The invention relates to the field of building materials, in particular to a reduction tempering agent and application thereof in treating steel slag. The reduction conditioning agent comprises 35 to 90 weight percent of a carbon-containing component; in the carbon-containing component, fixed carbon is greater than or equal to 40.0 wt%, volatile components are less than or equal to 50.0 wt%, and ash content is less than or equal to 10.0 wt%; the reduction tempering agent further comprises fluorite; the mass ratio of the carbon-containing component to the fluorite is (35-90): (2-40). According to the reduction tempering agent provided by the invention, the steel slag can be subjected to a chemical reaction at a relatively low temperature, a valuable metal iron resource is reduced and recovered, and the tempered steel slag with high gelling activity and no stability problem can be obtained and used as a building material resource, so that the whole full-quantization waste-free utilization of the steel slag can be realized, and the production cost is reduced. The large-scale comprehensive utilization of the steel slag is favorably improved.
本发明涉及建筑材料领域，尤其涉及一种还原调质剂及其在处理钢渣中的应用。所述还原调质剂包括35‑90wt％的含碳组分；所述含碳组分中，固定碳≥40.0wt％，挥发分≤50.0wt％，灰分≤10.0wt％；所述还原调质剂还包括萤石；所述含碳组分和所述萤石的质量比为(35‑90)：(2‑40)。本发明提供的还原调质剂不仅可以使钢渣在较低的温度下发生化学反应，还原回收有价金属铁资源，还可以获得胶凝活性高且无安定性问题的调质钢渣作为建材资源利用，可实现钢渣整体的全量化无废利用，有助于提高钢渣的规模化综合利用。
