alumina bricks manufacturer, producing high-quality alumina bricks. we have professional engineers and advanced technical guidance. We also have a lot of export experience. We can export cheap alumina bricks
Alumina bricks are a common refractory material and contain more than 48% alumina. They are neutral refractory materials. The bricks are made from bauxite or other high alumina raw materials by molding and firing. They have high thermal stability and can withstand high temperatures above 1770 C. alumina bricks are characterized by high refractoriness, high strength, resistance to acid attack and good thermal stability. alumina bricks are mainly used as linings for building electric iron furnaces, glass kilns or cement rotary kilns.
Fire clay & High Alumina bricks are special type of brick which are form of Refractory ceramic material. It is used for inner surface lining of Boiler, furnace, kiln, fireplaces & fireboxes. Quality of Bricks: We offer various quality bricks are IS-6, IS-8, PI - 30% to 90% Alumina offering high temperature resistance of 1100 C to 1700 C. Standard Sizes (inch): 9*4.5*3 / 9*4.5*2.5 / 9*4.5*2 / 9*4.5*1.5 / 9*4.5*1 Side Arch / Side Tapper, End Arch / End Tapper Sizes (inch) 9*4.5*3/2.75 9*4.5*3/2.50 9*4.5*3/2 9*4.5*3/1.5
High alumina brick is widely used for Widely used in blast furnaces, Hot Blast Stove,Steel ladle lining, Reheating furnace, Cement kiln, Tunnel kiln,boiler, coke oven, carbon furnace, glass kiln , Steel smelting furnace and various kiln lining and thermotechnical equipment, etc. want to know more
The Al2O3 content is more than 55%, and is calcined from a high-content alumina raw material such as a silicone raw material or a bauxite. High heat resistance and high temperature resistance at 1770 C and above. Has good slag resistance, mainly used in the masonry of steelmaking electric furnace, glass furnace, cement rotary furnace and so on. Characteristics of High Alumina Brick Price: 1.Refractoriness: More refractory than refractory clay bricks and semi-silica bricks, up to 1750-1790C, belonging to high-grade refractory materials. 2. Load softening temperature: Since the high aluminum has a high Al2O3 content, a low impurity content, and a low formation of the molten glass body, the fire-resistant softening temperature is higher than that of the refractory clay brick. However, since the mullite crystal has not yet formed a network structure, the load softening temperature is lower than the load softening temperature of the silica brick. 3. Slag resistance: High Al2O3 has high Al2O3 content, close to neutral refractory material, and can resist the erosion of acid slag and alkali slag. Because it contains SiO2, the resistance to alkali slag is less than acid resistance.
Product Description: We are a trusted name in manufacturing fire bricks which are a block of ceramic material used in masonry construction. These are sized to be layered with one hand using mortar. Our fire bricks are made from fire clay which is widely used as refractory insulating bricks to maintain insistent temperature. Thee bricks are extensively used in lining furnaces, kilns, fireboxes, and fireplaces.
