镁碳砖发展及生产工艺改进的研究

Study on the development and production process innovation of magnesia carbon bricks

镁碳砖是广泛使用的耐火材料,上世纪70年代始在结合剂、低碳化、抗氧化剂及新型添加剂等方面都进行了深入研究。目前,生产中仍存在易层裂、韧性差等问题。调整镁碳砖配合料颗粒级配、控制混合料湿度与优化压制过程等措施可以提高生产质量。

Magnesia carbon brick is a widely used refractory material.Since the 20 Century 70＇s,a lot of researches have been done in aspects of improvements of binder for magnesia carbon,low-carbon technology,anti-oxidants and the application of new additives etc.However,internal laminations still exist and intensity is low.Quality of production can be increased by adjusting the particle size distribution,controlling mixture humidity and optimizing the way of pressing.
