Silicon carbide bricks for incinerators and coke dry quenching furnace

Silicon carbide brick (SiC brick) is a refractory material made of SiC as the main raw material. Containing SiC72% ~ 99%. Divided into clay bonded, Si3N4 bonded, Sialon bonded, β-SiC bonded, Si2ON2 bonded and recrystallized silicon carbide bricks.

Silicon carbide bricks have high thermal conductivity, good wear resistance, thermal shock resistance and erosion resistance. Can be used for aluminum electrolysis tank lining, molten aluminum conduit and ceramic kilns with kiln furniture, large and medium-sized blast furnace body lower part of the furnace, furnace waist and furnace belly, aluminum refining furnace lining, zinc distillation canisters lining, etc., the silicate industry kiln shed plate and flame materials, chemical industry, oil and gas generator, organic waste combustion furnace;

Characteristics usually required of SIC refractories for incinerators:

(1) high strength and good abrasion resistance to resist the abrasion of solid materials and the scouring of hot gas flow;.

(2) good volumetric stability and acid resistance to resist the erosion of acidic substances in the furnace.

(3) Good shock resistance to resist the damage of the material by the change of furnace temperature; (4) Good CO erosion resistance.

(4) Good CO erosion ability to avoid chipping due to CO erosion due to its furnace lining; and

(5) Good facility (indeterminate); (6) Good heat resistance, heat resistance, heat resistance, heat resistance, heat resistance, and heat resistance.

(6) good heat resistance, heat insulation. In the selection of refractory materials, should be based on various forms of incinerator operating conditions and the performance of various refractory materials, select the appropriate refractory materials.
