超高温隧道窑用特种镁铬砖的性能

Property of Special Magnesia and Chrome Bricks Used in Tunnel Kiln with Superhigh Temperature

研究了再结合镁铬砖和低镁铬砖的理化性能和显微结构 .对其残砖进行了同样的研究 ,并对二者进行了比较 .结合使用情况 ,阐述了特种镁铬砖在超高温隧道窑使用过程中的变化机理 .

This paper deals with the physical property and the microstructure of the recombination magnesia and chrome bricks and the bricks contained low?level chrome.In addition,the research work has been made on the remains of such bricks and the comparision of these two kinds of bricks is also made.In the light of the conditions when they are used,the paper sets forth the changing mechanism of the special magnesia and chrome bricks in the process of being used in the tunnel kiln with superhigh temperature.
