Product Description
Product Overview:
Burning microporous alumina-carbon brick is a refractory product made of high-quality bauxite clinker, silicon carbide, carbon particles, graphite, and a binder after being mixed at a certain ratio, and then press-molded. Mainly used for masonry lining. According to the physical and chemical indicators, it is divided into WLT-1, WLT-2 and WLT-3.
