摘要

针对电厂燃煤锅炉某些部位的磨损，研制了一种新型耐热耐磨材料。实验表明，57号配方所配制的材料具有比其它材料更好的可施工性、耐热性和耐磨性。该材料以SiC和尖晶石为主要耐磨组分，以水玻璃型复合粘结剂为高温胶结材料，不但具有高于钢玉砖的耐磨性，而且具有无干燥收缩、强度高和高温体积稳定性好等优点。

Abstract

In view of intensive wear of some sections of coal—fired utility boilers a new wear—resistant refractory has been developed. Practice shows that the material made by directions No. 57 has the best properties in terms of engineering construction and

wear and heat resistance. This material uses silicon carbide and spinel as the main wear resisting components

and a complex of water glass as the main binder. This material has not only the wear resistance higher than alumina

but also the properties without shrinkage during drying

high volume stability during heating and high strength.
