Type of firebrick
Among them, the most common refractory bricks with the largest amount of aluminum silicon refractory products, such as common clay refractory bricks, high aluminum bricks, people often say that refractory bricks refer to clay refractory bricks, large dosage, cost-effective, Mainly used in carbon roaster, coke oven, small incinerator, small biomass gasifier, boiler, heating furnace, forging furnace, glass kiln, part of the rotary kiln, shaft furnace, steel blast furnace, hot metal ladle and so on, widely used.
Clay firebrick is divided into many types such as low porosity clay brick DD type, low creep clay brick DRN type, according to the national standard model PN type, N-1, N-2 to N4 and so on. The amount of high-aluminum refractory bricks is also relatively large, which is commonly divided into first-grade high-aluminum, second-grade high-aluminum, and third-grade high-aluminum bricks
