It is used for spraying the lining of hot blast stove body, blast furnace throat, furnace top and gas export system, hot blast stove top, hot blast pipe system, bituminous coal, protective layer of chimney system and furnace lining.

Blast furnace rising pipe, falling pipe and dust collector lining, semi-clean gas pipe, hot air pipe

Brown alumina and silicon carbide are used as raw materials, silicon nitride fine powder and composite binder are added, metal-non-oxide composite material system is used as the substrate, through non-oxide surface modification, and sol-gel molding process is used to achieve good fluidity, Excellent thermal stability, rapid drying performance and overall stability after drying. Generally used in the bottom of the blast furnace.

With brown corundum, silicon carbide, SiO micro-powder as raw materials, adding silicon nitride fine powder and composite bonding agent, a kind of pouring material suitable for rapid baking repair in the large blast furnace tuyere area has been developed, with excellent performance such as pressure strength, folding strength, post-burn line change rate, pore rate and erosion resistance. Generally used in the bottom of the blast furnace.
