Refractory buffer slurry is a kind of special refractory slurry which is made of compressible refractory materials to buffer the thermal expansion stress of refractory masonry. It is mainly used for the masonry of alumina silica and carborundum refractory masonry for blast furnace, hot blast furnace and other industrial furnaces which need to buffer thermal expansion stress.
