摘　　要：应用相图分析含硼炉渣硼元素的富集路线,并通过实验研究Mg O-B2O3-Si O2-Al2O3-Ca O渣系中硼元素富集的冷却制度.结果表明：冷却速率及2M g O·Si O2相对2Mg O·B2O3相的析出和长大有明显阻碍作用,硼的提取率随着1 500~1 200℃温度区间冷却速率的增加而增加.The enrichment route of boron in Boron-containing slag was analyzed by phase diagram. Moreover,the cooling mechanism of boron enrichment in MgO-B2O3-SiO2-Al2O3-CaO slag was researched by the experiment. It is shown that the cooling rate and 2MgO·SiO2 phase have significant inhibitive effects on the precipitation and increase of 2MgO·B2O3 phase. Meanwhile,the extraction rate of boron is improved with the increase of cooling rate as temperature ranging from 1 500 ℃ to 1 200 ℃.
