Method and system for stabilizing and grading utilization of steel slag
The invention relates to the field of solid waste emission reduction, in particular to a method and system for stabilizing and grading utilization of steel slag. The method comprises the following steps: obtaining hot-state steel slag after a steelmaking procedure; carrying out rolling and first cooling on the hot-state steel slag, and then carrying out hot disintegration and second cooling under the atmosphere condition of carbon dioxide, so as to obtain stabilized steel slag; carrying out N-stage magnetic separation on the refined steel slag to respectively obtain slag steel and steel slag with N particle sizes; the slag steel is returned to the steelmaking procedure, and a steel product is obtained; classifying the steel slag in the N particle size ranges to obtain building materials with different particle sizes; wherein N is greater than or equal to 1 and N is a positive integer; the system comprises: a hot-state steel slag treatment unit, wherein the hot-state steel slag treatment unit comprises a rolling subunit and a hot-stuffy carbonation subunit; the cold solid state treatment unit comprises a magnetic separation subunit, a screening subunit and a grinding subunit; the steel slag is subjected to hot disintegration treatment in a carbon dioxide atmosphere, deep stabilization of the steel slag is achieved, and follow-up graded utilization is facilitated.
本申请涉及固废减排领域，尤其涉及一种钢渣稳定化分级利用的方法及系统；所述方法包括：得到炼钢工序后的热态钢渣；将热态钢渣进行辊压和第一降温，后在二氧化碳的气氛条件下进行热闷和第二降温，得到稳定化的钢渣；将细化钢渣进行N级磁选，分别得到渣钢和N个粒径的钢渣；将渣钢返回炼钢工序中，得到钢制产品；将N个粒径范围的钢渣进行分类，得到不同粒径的建筑用料；其中，N≥1且N为正整数；所述系统包括：热态钢渣处理单元，热态钢渣处理单元包括辊压子单元和热闷碳酸化子单元；冷固态处理单元，冷固态处理单元包括磁选子单元、筛分子单元和粉磨子单元；将钢渣进过二氧化碳气氛的热闷处理，实现钢渣的深度稳定化，方便后续分级利用。
