    摘要

  • 这是一篇冶金陶瓷材料领域的论文。镁铬质耐火材料由于具有优异的高温强度和抗渣性，并且具有良好的使用性能，被广泛应用于炼铜工业。本文从理论上综述了铜冶金用镁铬耐火材料侵蚀机理的研究现状，并明晰了炉渣温度、原料物性如品位和Cr2O3的含量以及添加剂因素影响镁铬耐火材料抗渣性的作用机制，最后依据研究现状总结了提高镁铬耐火材料服役寿命的主要途径，为未来镁铬耐火材料的结构设计和性能调控提供指导与帮助。

    This is a paper in the field of ceramic materials for metallurgy. Magnesia chrome refractory is widely used in copper industry due to its excellent high temperature strength, fine slag corrosion resistance and good performance. In this paper, the research status of corrosion mechanism of magnesia chrome refractories for copper metallurgy is summarized theoretically, and the effect and action mechanism of factors on the service life of metallurgical furnace was clarified, such as slag temperature, grade, Cr2O3 content and additives in magnesia chrome bricks. Finally, according to the research status, the main ways to improve the service life of magnesia chrome refractories are summarized, which will provide guidance and help for the structural design and performance control of magnesia chrome refractories in the future.
