by mixing 80wt% Si-Mn slag powder, 10wt% lime, and 10wt% anhydrite. The compressive strength of mortar samples reaches 51.48 MPa after 28 d curing. The analyses of X-ray diffraction (XRD) and scanning... and 27Al and infrared spectroscopy (IR) analysis show that aluminum decomposition from tetrahedral network of the slag glass and its subsequent migration and re-combination play an important role......
="ChDivSummary">Traditional processes for treating vanadium slag generate a huge volume of solid residue and a large amount of harmful gas,which cause serious environmental problems.In this study,a new process for the comprehensive utilization of vanadium slag was proposed,wherein zeolite A and a V2O5/TiO2 system were synthesized.The structural properties of the as-synthesized zeolite......

电熔镁钙砂的加入方式 王健东1,孙加林1,高心魁2,潘波1,尹国祥2 (1.北京科技大学材料科学与工程学院;2.营口青花耐火材料股份有限公司) 摘要:以电熔镁砂和石墨为原料制备CaO含量不同的MgO-CaO-C砖,利用回转法对比了试样抗CaO-SiO2渣性能.结果表明:电熔镁钙砂的加入方式影响抗渣侵蚀及挂渣性能,在CaO含量相同时,电熔镁钙砂全以骨料加入时的挂渣性能较好,而抗渣侵蚀性能较差.只有当电熔镁钙砂骨料与粉料以一定比例加入,即当挂渣性能与抗侵蚀性能均衡时,MgO-CaO-C砖的残厚才最大. 关键词:电熔镁钙砂; 抗侵蚀; 挂渣; fused magnesia-calcia slag corrosion resistance slag adhesion; [全文内容正在添加中] ......
