The buffered refractory slurry developed by our company is mainly applied to the refractory brick masonry of ironmaking blast furnace and hot blast stove. The compressibility of the refractory buffer mud under high temperature load is used to alleviate the thermal expansion stress of refractory brick masonry, and at the same time refractory buffer slurry has a certain fire resistance and can maintain the tightness and integrity of the lining. The refractory mud produced by our company is mainly high alumina refractory buffer mud and non-aqueous SiC refractory buffer slurry.
