摘要
介绍了镁资源综合利用的途径及镁质耐火材料在高温工业中的发展情况。在镁资源综合利用方面着重介绍了金属镁的制取、镁水泥、氢氧化镁阻燃剂及轻质碳酸镁、轻质氧化镁、硫酸镁的制取与用途。在镁质耐火材料的发展情况中,从应用理论系统地分析并介绍了镁质耐火材料在高温工业:炼钢、有色金属冶炼、水泥窑及垃圾焚烧熔融炉的应用情况及其发展,并介绍了MgO-CaO材料的抗侵蚀和水化问题,以及尖晶石材料与镁质不定形耐火材料的研究现状和发展趋势。
This paper presents the ways of comprehensive utilization of the natural magnesium-containing resources and the trends of the MgO-based refractories used in high-temperature industries. In the first part, the uses and productions of metal Mg, sorel cement, Mg(OH)2 fire retardant, light magnesium carbonate, light magnesium oxide and magnesium sulphate are described. In the second part, the developments of MgO-based refractories used in steelmaking process, non-ferrous metallurgy, cement rotary kiln and waste melting furnace are described from some applied theories, and it contains corrosion resistance and slaking resistance of MgO-CaO materials, chrome-free bricks such as MgO-CaO-ZrO2, MgO-MgO · Al2O3, MgO-MgO · Al2O3-ZrO2, MgO-MgO · Al2O3-2MgO-TiO2 and MgO-FeO · Al2O3, and MgO-containing monolithic refractories, etc.
