What are clay insulating refractory bricks?
It is a heat-insulating refractory product with an Al2O3 content of 30% to 48% made of refractory clay as the main raw material. Its production process adopts the burnout addition method and the foam method. Refractory clay, floating beads, refractory clay clinker are used as raw materials, and binders and sawdust are added. After batching, mixing, molding, drying and firing, a product with a volume density of 0.3~1.5g/cm3 is obtained.
What are the advantages of clay insulating refractory bricks?
It has excellent thermal insulation and fire resistance. Compared with traditional heavy refractory bricks, its outstanding advantages are: lightweight structure reduces equipment load and reduces heat energy loss; closed-cell structure effectively blocks heat conduction; good compatibility with acidic and neutral media; easy construction, and can be processed into special-shaped bricks to adapt to complex structures.
In what fields can clay insulating refractory bricks be used?
It is widely used in metallurgical furnace insulation layer, ceramic roller kiln, boiler insulation lining and other scenarios, especially suitable for working conditions with high requirements for thermal insulation performance and no direct contact with molten materials. It should be noted that despite its excellent performance, it needs to be used in conjunction with heavy refractory materials in extreme environments such as mechanical shock or direct contact with slag erosion to ensure the overall service life of the equipment.
