High Alumina Insulation Brick By Henan Hongtai Kiln Refractory Co., Ltd.

Loaded with vast industrial knowledge and expertise, we have emerged as a major Exporter, Manufacturer & Supplier of High Alumina Insulation Brick in Zhengzhou, Henan, China.
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 a , some can up to 1550 a .
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
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 a .
