High Alumina Products Suppliers and Manufacturers

High alumina description generally means content of alumina percentage is higher than 45. Alumina is one of the most chemically stable oxides, and it offers excellent hardness, strength and spalling resistance. Alumina refractories are suitable for lining furnace operating up to 1850C. Alumina refractories have the advantages of a high resistance in oxidizing and reducing atmosphere and is extensively used in heat processing industries.

High Alumina Products

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.

High alumina castable is a refractory castable made of high alumina raw material with binder and aggregate in traditional ratio.On the basis of the preparation of high strength and high aluminum castable, the granule gradation is adjusted, different admixtures are added, cement dosage is reduced, performance is improved, medium temperature strength and softening temperature under load are increased, thermal conductivity is reduced, and thermal stability is good.The furnace body structure integrity is strong, the air tightness is better than the brick furnace, extends the furnace life, saves the furnace repair cost, the economic benefit is remarkable as the high aluminum refractory castable characteristic.

High Alumina Refractory Cement is manufactured from Calcined Alumina and high purity lime. It is used as a binder for all types of castable refractories. Ashapura offers two ranges; HARB 50 and HARB 70 with minimum alumina content of 50% and 70% respectively.

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.

As per standards. Loose & Pallets

High alumina firebricks are classified according to the alumina content which is from lowest 48% to highest 95%, manufactured from mineral of bauxite, corundum, etc. By mixing, press-forming, drying, sintering and machining. High alumina bricks feature stable mechanical strength and thermal shock resistance, with high refractoriness of no lower than 1880¡æ, high alumina bricks are commonly used as refractory lining exposed to heat directly or backup insulation linings in various types of industrial kiln or laboratory furnace.
