Alumina silica fire bricks include: silica bricks, high alumina bricks, clay bricks, corundum bricks and other refractory bricks. The alumina-silica firebrick sold by Kerui refractory is a kind of refractory brick with high refractoriness, good erosion resistance, slag resistance and high strength. Alumina silica bricks refractory bricks can be used in various thermal equipment.
Alumina silica fire bricks description
Alumina silica refractory bricks are based on AL2O3-SiO2 chemical composition and include the following four types:
Silicon bricks are acidic refractories with more than 94% silica content and a density of 2.38 g/cm3. Silicon bricks are widely used in glass melting kilns, coke ovens, hot air furnaces and other high-temperature thermal equipment, and are not suitable for heating equipment with temperature fluctuations below 600°C.
High alumina brick is a kind of alumina silicate based refractory material with alumina content greater than 48%. It is calcined from bauxite raw material or Al2O3 material, and can also be matched with electrofused corundum, sintered alumina, synthetic mullite, clay, etc. depending on the calcined clinker. High alumina bricks are widely used in cement and glass building materials industry, steel smelting industry, petrochemical industry, etc.
Fire clay bricks are made of clay (including shale, coal gangue and other powders) as the main raw material, treated with clay, shaped, dried and roasted. Fire clay bricks are mainly used in blast furnaces, hot blast furnaces, heating furnaces, non-ferrous metal smelting furnaces, etc.
Corundum bricks are refractory products with alumina content more than 90% and corundum as the main crystalline phase. Corundum bricks are mainly used in iron making blast furnace and blast furnace hot blast furnace, steel making furnace outside refining furnace, water slider, glass melting kiln and petrochemical industrial furnace, etc.
Alumina-silica refractory brick is a kind of refractory brick with low price and good quality sold by kerui refractory material suppliers. Alumina-silica refractory bricks are made of refractory raw materials by molding and then fired at high temperature, mainly used for building smelting furnaces with refractoriness of 1580~1770℃. Alumina-silica refractory bricks can be divided into fired bricks, unfired bricks, fused cast bricks and refractory insulation bricks according to the manufacturing process. Besides, according to the different composition of refractory bricks, they can be divided into five types, such as alumina-silica refractory bricks, alkaline refractory bricks, zirconium bricks and carbon bricks. Any kiln does not use only one kind of refractory bricks, but needs several different refractory bricks to be used together.
Finally, how to buy high quality high alumina fire brick near me?
First, no matter what type of furnace you plan to build, a quality aluminum-silicon refractory brick must be your first choice. If you buy refractory bricks locally, you can go to the field to see if the refractory manufacturer you choose can provide you with the refractory bricks you need, and buying locally also saves you long-distance shipping costs.
Secondly, if you don’t choose the right refractory bricks locally, you can also buy refractory bricks from abroad, such as the Kerui refractory material manufacturer in Zhengzhou, China. We can provide you with professional advice on the purchase of refractory bricks as well as construction. Besides, we can also send professional engineers to your country to help you design and build your kiln.
