摘要:
镁碳耐火材料因其中含鳞片石墨等碳组分而具有优异的抗热震性和抗高温熔渣侵蚀能力，被广泛用作钢铁冶炼用转炉、电炉、钢包等炉衬材料。为满足洁净钢冶炼技术、钢铁冶金节能减排、资源高效利用的需求，镁碳耐火材料的低碳化具有重要的现实意义。然而，单纯地降低镁碳耐火材料中鳞片石墨的含量，势必会造成材料高温使用性能下降，尤其是抗热震性下降。为此，近年来国内外研究者主要从碳源的选择、结合剂的改性、抗氧化剂的优化和原位形成陶瓷相的控制等方面开展了大量卓有成效的工作。主要从纳米结构基质的构筑、结合剂碳结构的优化及外加剂的引入与陶瓷相的调控出发，综述了国内外低碳化镁碳耐火材料的研究进展，提出了高强韧复合化/轻量化镁质骨料的制备、新型抗氧化剂的研发及不同抗氧化技术的结合使用、复合纳米碳/陶瓷相协同强韧化的调控、含纳米碳复合粉体的制备以及鳞片石墨替代材料的选择等发展方向，期望为低碳化镁碳耐火材料的研究和工业应用提供参考。
Abstract:
MgO-C refractories are widely used as the lining materials in steelmaking industries such as basic oxygen furnace, electric arc furnaces and steel ladles owing to their excellent thermal shock resistance and corrosion resistance originated from the presence of flake graphite and other carbon sources. In order to meet the requirements of clean steel smelting, low carbon society and effective usage of resources, it is greatly important to develop low-carbon MgO-C refractories. Nevertheless, the high temperature performance (especially thermal shock resistance) will be decreased significantly when the content of flake graphite in MgOC refractories is reduced. Therefore, much effort based on the selection of carbon sources, modification of binders, optimization of antioxidants and control of insitu formed ceramic phases was performed to improve the properties of the refractories in the past 20 years. In this review, the recent progress on low-carbon MgO-C refractories is summarized, and the future investigation work including the fabrication of composite/lightweight magnesia-based aggregates with high strength and toughness, the development of new antioxidants, the combined utilization of different antioxidation techniques, the control of synergistic strengthening and toughening of composite nano-carbon/ceramic phase, the preparation of composite powders containing nano-carbon and the selection of flake graphite substitute materials is also proposed, with the aim to provide the guidance for the development and application of low-carbon MgO-C refractories.
