Product description

Silicon carbide refractory bricks manufactured by CH Refractories has high thermal conductivity, good wear resistance, thermal shock resistance and corrosion resistance. Can be used for aluminum electrolytic cell lining, molten aluminum conduit and ceramic kiln kiln utensils, large and medium-sized blast furnace body, furnace waist and furnace belly, aluminum refining furnace lining, zinc distillation tank lining, etc. Silicon carbide brick is silicon carbide (sic) as the main raw material, according to the requirements with a variety of bonding agents, by high pressure molding, corundum silicon carbide brick products have good thermal stability and high thermal conductivity, and good corrosion resistance, is an ideal energy-saving material for industrial kilns.

Application:

The application of silicon carbide refractory bricks are distinguished according to different binder: Clay bonded silicon carbide bricks are refractory products fired with silicon carbide as the main raw material and clay as the binding agent. This kind of silicon carbide bricks are used as ceramic kiln furniture (shed boards, brackets, saggers, etc.), muffle covers for muffle furnaces, furnace lining bricks for aluminum refining furnaces, distillation pots for zinc distillation furnaces, cement rotary kiln coolers, etc.
