High Alumina Bricks Dealers in Jaipur

We are offering high alumina bricks. in order to meet out the requirements of neutral refractories, where safe working temperature is more than 1300 degree centigrade & slag reaction is severe, we are manufacturing high alumina bricks as per customer requirements. High refractoriness increases with increasing alumina content. These bricks have high mechanical strength and excellent load-bearing properties at high temperatures besides having fair to excellent resistance to spalling. These high alumina bricks have high resistance to corrosion by many basic slags and fluxes and fair resistance to acid slags. These high alumina bricks are suitable for cement rotary kilns, laddle lining, glass industries, blast furnaces stoves & checkers, electric furnace roof & other miscellaneous industries.

We are offering alumina fire bricks. we provide alumina fire bricks in standard as well as customized shapes and sizes, according to the requisites of the clients. High quality alumina fire bricks are sure to provide excellent performance with their quality.

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. We have different kind of High Alimuna Bricks mainly : 60% ALUMINA GRADE : The 60% alumina class is a large, popular class of products. These brick are used in the steel industry, as well as rotary kilns. Brick in this class are made from a variety of raw materials. Some are produced from calcined bauxitic kaolin and high purity clay to provide low levels of impurities. As a result of firing to high temperature, these brick have low porosity, excellent hot strength and creep resistance, and good volume stability at high temperatures. 70% ALUMINA GRADE : This is the most frequently used high- alumina product class because of its excellent and cost-effective performance in multiple environments. Applications include the steel-industry and cement and lime rotary kilns. Most brick in this class are based on calcined bauxite and fireclay. Brick are usually fired to fairly low temperatures to prevent excessive expansion in burning which causes problems in final brick sizing. Expansion is caused by reaction of the siliceous ingredients with bauxite to form mullite. The brick typically undergo large amounts of secondary expansion when heated. This is advantageous in reducing the size of joints between brick and providing a tight vessel structure, e.g., a rotary kiln. A higher cost and higher quality alternative to producing a 70% alumina brick is represented by brands based on high purity calcined bauxitic kaolin. These brick have superior high temperature strength and refractoriness and significantly lower porosity than typical products based on calcined bauxite. Due to their more homogeneous structure, they show somewhat less expansion on reheating than bauxite-based products. 80% ALUMINA GRADE : These products are based primarily on calcined bauxite with additions of various amounts of other fine aluminas and clay materials. They are usually fired at relatively low temperatures to maintain consistent brick sizing. Most brick in this class have about 20% porosity, good strength and thermal shock resistance. Because they are relatively inexpensive, perform well and are resistant to most slag conditions present in steel ladles, they are used extensively in steel ladle applications. 90% AND 99% ALUMINA GRADE : These brick contain tabular alumina as the base grain and may include various fine materials such as calcined alumina, clay and fine silica. As these brick generally have low impurity levels, alumina and silica typically make up 99% of the chemical composition. Usually, the only mineral phases present are corundum and mullite. Properties such as high hot strength, creep and slag resistance benefit from this purity level.
