JBTC offers exclusive range of HIGH ALUMINA bricks with various qualities we guarantee our bricks to be of superior quality.
The term High Alumina refers to the bricks having AL203 content of 47.50% atleast or higher
High alumina bricks require bauxite to be manufactured. Bauxite is a naturally occurring mineral which is also found in kaolin-tic clays. These two substances are taken as raw materials and roasted together to produce a high refractory material.
This material is used to make high alumina bricks that find applications in not only kilns and furnaces but also cement, iron and steel, and glass industries. Our high alumina bricks are not only very hard and thermal resistant but also good at electrical insulation.
High-alumina brick are resistant to acid slags, that is, those high in silica. Basic components in slag, such as MgO, CaO, FeO, Fe2O3 and MnO2 react with high-alumina brick, particularly brick high in silica. As Al2O3 content increases, slag resistance generally improves
We offer these bricks with varying percentages of alumina and Fe2O3 and in different shapes and sizes according to the requirement.
High alumina brick is a kind of neutral refractories. It is manufactured from bauxite or other refractory raw materials within high alumina formed by molding and calcination. High aluminum refractory bricks has high refractoriness, high load softening temperature, thermal shock stability, good slag resistance, acid, alkali, peeling resistance, erosion resistance and so on.
High alumina brick is mainly used for electric furnace top, blast furnace, hot air stove, ladle, cement kiln, glass kiln and other thermal furnace lining. High alumina brick is widely used in iron, steel, chemicals, cement and other industries.
