Insulation refractory products refers to the products with porosity of not less than 45%. Insulation products are characterized by high porosity, small bulk density, low thermal conductivity, good insulation performance. It can preserve heat,as well as resistant heat, can be used as a insulation layer for a variety of thermal insulation equipment, and some can also be used as a working layer, is energy-saving materials to build a variety of kiln. Comparing with general dense refractory products, it is more effective to reduce the heat loss by 40% to 50%, especially for non-continuous thermal equipment.

High aluminum insulation refractory brick

High aluminum insulation refractory bricks are made of bauxite as the main raw material with al2o3 content of not less than 48%. In order to improve the product performance, industrial alumina, corundum, sillimanite, kyanite, silica fine powder are added to get the different bulk density. the working temperature Is 1250-1350 C, some can up to 1550C.

Production Process:

High-aluminum insulation brick mostly use foam production, the product bulk density is 0.4-1.0g / cm3, can also use burnout process.

Application of high alumina brick

Note:High aluminum insulation refractory bricks can be used for masonry Insulation layer and no strong high temperature melting materials erosion site. When directly contact with the flame, the surface contact temperature of high alumina insulation brick shall not be higher than 1350 C.
