摘　　要：分析钢渣碳化过程中矿物变化、微观形貌及钢渣颗粒级配对其碳化的影响,探讨碳化钢渣制品经济合理的颗粒级配。结果表明:纯钢渣碳化制品的适宜颗粒级配为w(钢渣微粉)=45%,w(钢渣粗粉)=40%,w(钢渣粗颗粒)=15%;钢渣混合矿渣制品适宜的颗粒级配分别为w(钢渣微粉)=10%,w(钢渣粗粉)=35%,w(钢渣粗颗粒)=5%,w(矿渣粗颗粒)=50%。颗粒级配对钢渣碳化具有显著影响。在相同的碳化条件下,相对于钢渣粗粉,钢渣微粉更易于碳化。Variation of minerals and micro-morphology in the process of carbonation were analyzed, and the effects of particle size distribution on steel slag carbonation were studied to explore the reasonable particle size distribution of steel slag. Experimental results show that the optimal particle size distribution of steel slag product is fine powder of steel slag w = 45 %, coarse power of steel slag w = 40 % and coarse granule of steel slag w = 15 % , and that steel slag mixed with blast furnace slag product is fine powder of steel slag w = 10 % , coarse powder of steel slag w =35 % , coarse granule of steel slag w =5 % , and coarse granule of blast fumace slag w =50 %. Particle size distribution of steel slag has significant effects on carbonation. Under the same carbonated conditions, fine powder of steel slag is prone to be carbonated much more than the coarse powder of steel slag.
