The bricks we offer are widely applauded for their dimensional stability, compressive strength and durability. Moreover, super heat duty and high alumina fire bricks are the products made from different fractions of refractory grog, fire clays and calcined bauxite of high purity. The different fractions of these raw materials are mixed in counter current mixers and plugged for obtaining homogeneous mixture. The mixture obtained hence, is then pressed in high capacity presses to give the desired shape and size. These pressed shapes are fired in high temperature tunnel kiln at 1300°c and above. These bricks are manufactured as per is: 6 and is: 8 specifications and high alumina in the range heat 5050 to heat 88 in standard, arch and special shapes.We provide these quality assured bricks to the clients at nominal rates.
Our High Alumina Bricks have wide application in steel plants sector, where these are used in various kilns and furnaces

Circle fireclay bricks are specialized fire bricks that are used to construct circular structures or lining in high-temperature environments. The circular shape of these bricks allows for smooth and continuous lining without the need for excessive cutting or fitting. This makes them more efficient to use in curved or circular structures, helping to ensure a reliable and durable construction in high-temperature environments. Applications of Circle Fireclay Bricks: Kilns: Circle fireclay bricks are commonly used to build the inner lining of kilns, which are used for firing ceramics, pottery, and other materials at high temperatures. Furnaces: In industrial settings, circle fireclay bricks are used to construct the interior of furnaces, which are used for melting metals or processing other heat-intensive materials. Chimneys: The circular shape of these bricks makes them ideal for constructing chimneys and flues, where they can withstand the high temperatures and corrosive byproducts of combustion. Forges: Circle fireclay bricks are also used in blacksmith forges, where they create a heat-resistant lining to contain the intense heat needed for metalworking. Pizza Ovens: In traditional pizza ovens, circle fireclay bricks are often used to line the cooking chamber, as they can endure the high temperatures required for baking pizzas.

magnesia carbon bricks . Our high volume output, combined with stringent manufacturing methods, has made us a strategic Magnesia carbon brick is a no-burn alkaline refractory material. It enhances corrosion resistance and slag resistance. The product range is based on magnesia composite materials. These bricks show excellent resistance to thermal shock and corrosion at high temperatures and are widely used in the steel industry. Its high melting point and resistance to hydration make it an ideal refractory material. Steelmaking requires extreme chemical, thermal and mechanical conditions that require materials with high performance that can withstand the action of steel and slag. Both magnesia carbon and magnesia alumina carbon are capable of providing such properties. In addition to manufacturing standard brick sizes (MC 8/10/12/14/18), we are able to produce specialized shapes to suit all reformer and electric arc furnace designs.
