Abstract

Abstract: High carbon contents (12 mass%-20 mass%) in traditional magnesia-carbon (MgO-C) refractories lead to their easy oxidation,failing to meet the requirements of modern clean steel smelting and low-carbon environmental protection.Therefore,developing high-performance low-carbon and ultra-low-carbon MgO-C refractories has become a research hotspot in the industry.The current research achievements in raw material optimization of low-carbon MgO-C refractories were summarized,focusing on the optimization of magnesia aggregates,the introduction of nano-carbon sources,the composite and modification of binders,and the efficient utilization of antioxidants.The future research directions were prospected,aiming to provide references for promoting the further development of low-carbon MgO-C refractories.

Key words: low-carbon MgO-C refractories, magnesia aggregate, binder, composite and modification, antioxidant

摘要： 传统镁碳耐火材料的高碳含量(碳的质量分数12%~20%)导致其易氧化,不符合现代洁净钢冶炼及低碳环保的要求。因此,开发高性能低碳乃至超低碳镁碳耐火材料成为行业研究的热点。本文中总结了当前低碳镁碳耐火材料原料优化的研究成果,重点讨论了镁砂骨料优化、纳米碳源的引入、结合剂的复合与改性以及抗氧化剂的高效使用等方面。并展望了未来的研究方向,旨在为推动低碳镁碳耐火材料的进一步发展提供参考。
