溅渣护炉条件下转炉镁碳砖的特性与改进探讨

Discussion on Characteristics and Improvement of Various Magnesia-carbon Bricks Used in Converter under Gunning Slags for Lining Protection

结合溅渣护炉条件下转炉镁碳砖的组成、性能及对造渣、导热系数的分析，讨论了镁碳砖的设计与改进的基本原则变化，提出了低导热系数低石墨含量镁碳砖的设计思路。

According to the analysis on constitution and properties of magnesia-carbon bricks under slag gunning for lining protecttion as well as analysis on slagging and coefficient of thermal conductivity,the chang in basic principles of design and improvements of magnesia-carbon bricks are discussed,and also the design thought of lwo-graphite-content magnesia-carbon bricks with low coefficient of thermal conductivity is put forward herein.
