1,Description of general high alumina brick:
Such product selected calcined Bauxite and high quality combined clay as main raw materials. After shaped with brick machine above 600 tons and fired at 1450-1470 °C , we can get this product. With high Al2O3 content, the product have good high temperature performance, so it is widely used in all kinds of industrial furnace and high temperature parts to prolong the life of furnace. This product is widely used in industrial furnace and lining .

3,Specifications of high alumina brick: JLZ-55, JLZ-65 and JLZ-75. Their working temperatures are 1400℃,1450℃ and 1500℃ respectively.They are applied to different parts of high temperature industrial furnaces.
4,Product knowledge: The firing temperature of this kind of product is 1380 ~1480℃.The intrinsic mineral phases of the product are mainly corundum phase and mullite phase.Therefore, this kind of product has high temperature resistance and is widely used. It can be said that as long as it is an industrial kiln, it is necessary to build this kind of product.
5,In the firing process of this kind of products, we should pay attention to the following problems: the lining sand should be spread between the bricks, so that there is a certain gap between the bricks, in order to avoid bonding together. The heating rate should be slow, too fast will lead to red or black core products, reduce product performance.
6,Our company has rich experience in the production and application of this kind of products, which can provide users with relevant services free of charge and ensure the rational use of this kind of products by users.
