What are the Exactly Details of High Alumina Lightweight Insulation Fire Bricks?
What is High Alumina Lightweight Insulating Fire Brick ? From some side, it is an ideal insulation refractory, a high alumina insulating brick with advantages associated with high strength, low thermal conductivity, good insulation and low price. With regard to various industrial kilns and furnaces, it is the kind of essential refractory for energy saving and even temperature preservation. High Alumina Lightweight Insulation Fire Bricks High Alumina Lightweight Insulating Fire Bricks can also be called lightweight high alumina bricks. It consists of more than 48% Ai2O3 and mainly includes mullite and glass phase or perhaps corundum. High alumina insulating bricks are generally made from high bauxite and a little bit of clay. After raw materials are grounded, it is made in to mud. Then it will be cast and molded and fired at 1300～ 1500℃. Manufacturing Process of Lightweight High Alumina Bricks . Sometimes, industrial alumimum will be used to replace bauxite. Inorganic compoun...
