High-Alumina Poly Light Insulation Brick for High-Temperature Furnace Insulation Bricks

High alumina poly lightweight bricks are also called lightweight high alumina bricks, high alumina insulating bricks or high alumina insulating bricks. Lightweight high alumina bricks use high alumina bauxite clinker and a small amount of clay as the main raw materials. After fine grinding, it is cast as a slurry by gas generation or foam. High alumina poly light weight heat insulation refractory brick. High alumina poly light ball insulation brick for ceramic tunnel kiln, lightweight high alumina brick, 0.8, 1.0 body density optional. Good heat insulation effect and high compressive strength. Lightweight thermal insulation refractory brick Fire brick 3 pieces, 230*114*30mm.

High-temperature furnace insulation brick product application. Widely used in kiln lining (not corroded by solution) and heat insulation layer in metallurgy, machinery, ceramics and chemical industry. It is an ideal energy-saving product. Use temperature below 1350°C.

Characteristics and materials of refractory mortar for high-alumina heat-insulating refractory bricks

High-alumina heat-insulating refractory bricks are heat-insulating refractory products made of bauxite as the main raw material with an A1₂0₃ content of not less than 48%. High-aluminum poly light brick Lightweight thermal insulation refractory brick Used for high-temperature kiln lining Good thermal insulation performance and corrosion resistance. Aluminum heat-insulating refractory bricks mainly use bauxite as raw material, combined with clay as raw material, mixed with binder and sawdust, in order to improve product performance, add industrial alumina, corundum, sillimanite, kyanite, silica fine Powder can be used to produce products with different bulk densities and different maximum operating temperatures. Usually, the operating temperature is 1250~1350°C, and some can reach 1550°C.

High-alumina heat insulation bricks are mostly produced by foam method, and the bulk density of the product is between 0.4~1.0g/cm₃, and can also be manufactured by burning embers.

High-alumina heat-insulating refractory bricks can be used to build heat-insulating layers and parts without strong erosion and erosion of high-temperature molten materials. When in direct contact with the flame, the surface contact temperature of general high-alumina heat-insulating refractory bricks shall not be higher than 1350°C. Mullite heat-insulating refractory bricks can directly contact the flame, and have the characteristics of high temperature resistance, high strength, and remarkable energy-saving effect. It is suitable for lining of pyrolysis furnace, hot blast furnace, ceramic roller kiln, electric porcelain drawer kiln and various resistance furnaces. The corundum-mullite insulating refractory brick with an A1₂0₃ content of 82.4% can be used as a furnace lining at 1550°C.

Refractory clay is also called fire clay or joint compound. It is used as a joint-laying material for refractory product masonry.

According to the material, it can be divided into clay, high alumina, silicon and magnesia refractory mud. It is composed of refractory powder, binder and admixture. Almost all refractory raw materials can be made into powder for configuring refractory mud. Ordinary refractory mud made of refractory clinker powder plus appropriate amount of plastic clay as binder and plastic is called ordinary refractory mud. Its normal temperature strength is low, and ceramic bonding is formed at high temperature to have higher strength. The chemically bonded refractory mud, which uses hydraulic, air-hardening or thermosetting bonding materials as a bonding agent, produces a certain chemical reaction and hardens before the bonding temperature is lower than the formation of ceramics. Lightweight clay bricks, thermal insulation bricks, standard T-3 refractory bricks, specific gravity 0.6, 0.8, 1.0, 1.2, 1.3. The particle size of refractory mud varies according to the requirements of use, and its limit particle size is generally less than 1mm, and some are less than 0.5mm or finer.

The material of the refractory mud should be considered to be consistent with that of the masonry refractory products. In addition to being used as a joint material, refractory mud can also be used as a protective coating for linings by smearing or spraying. Refractory mud is mainly used in coke ovens, glass furnaces, blast furnace hot blast stoves, and other industrial furnaces.

Applied industries include: metallurgy, building materials, machinery, petrochemicals, glass, boilers, electric power, steel, cement, etc. Coke oven thermal insulation lightweight refractory bricks, high aluminum poly light insulation bricks, high temperature furnace insulation bricks.
