Magnesite bricks, This range of fired and chemically bonded magnesite bricks is suitable for use in backup applications of EAF, LD converter, steel ladle and can be supplied with or without steel clad. With the increased focus on fuel efficiency in glassmaking and increase in furnace life necessitated by economy, the use of high purity magnesite bricks in glass regenerator has become universal. Maithan offers the MGIS range of low iron high purity Magnesite bricks manufactured with high grade Sea water and sintered natural magnesia. These refractories are distinguished by their high density and resistance to alkali, sulphur, silica carry over and fume attack. Solutions based on this range can be tailor made depending on the cost economics, capacity and life expectancy of a glass furnace.

Our supply range of high alumina bricks are useful in the construction of steel refining furnaces, glass tanks, ceramic kilns, enamel kilns and rotary cement kilns. The high alumina bricks comprise of a blend of alumina and ferrous content and their apparent porosity is 15 to 23%. They have high refractoriness and can sustain themselves easily even in high temperature. This is the reason why they are used as high temperature equipments in various industries. These high alumina bricks are highly resistant to corrosion due to metal fluid and oxidation.

In conformity to IS 4860 & IS 4457.It is very strong lining for equipment & Floor & capable to withstand corrosion, heat & also mechanical impact. It is usually laid over the surface & over a suitable membrane like Bituminous mastic, PVC, Rubber lining etc. A typical specification for brick lining is to select suitable acid proof mortar for bedding purpose & bricks joints are to be pointed with resin cements to suit the duty conditions to which it is subjected.

Clay Brick is integral to the sustainable development of communities across our beautiful country, having been used as the building material of choice since our ancestors. The long life span and durability afforded by clay brick ensures that clay brick homes last for generations, while also instilling a sense of place, worth, comfort and security in the lives of our people. When one considers the long-term performance, occupancy comfort, colour-fastness and life cycle value to be enjoyed from living in a clay brick house, clay brick stands out as a pillar of value now and in the future.   Our Clay bricks are the ideal solution due to Highest compresive strength, and its appropiate for any kind of constructions . It also offering anti-slip flooring that gives a better grip and does not wear out easily. its best for heavy wall applications. Our Clay bricks have exceptional strength to withstand the toughest daily grind and the heaviest wear and tear. Manufactured under hydraulic pressure, they are more wear-resistant than ordinary clay bricks. An ideal choice for walls, Roofs, pathways, swimming pool decks, building compounds, petrol pumps, warehouses and bunglows areas

These bricks are manufactured by the sawdust process using selected grades of china clay and kyanite for hot face as well as back up applications. Particularly notable is the HFK brick, which is one of the most economical insulations in its classification temperature. Rajhans also manufactures high CCS insulation tiles, RHR HSI for glass melter bottom and can supply the same in any size. This range of bricks has been entirely developed through indigenous research and is formed by the vibro-casting method. Vibro-casting ensures extremely low thermal conductivity and proportionately high strength. These bricks are engineered for cold face as well as hot face applications and can withstand temperatures of upto 1500°C. Tailor made solutions for kilns and furnaces based on vibro-cast bricks can be forwarded with cost benefit analysis in terms of energy savings.High Alumina insulationsThis range of insulation bricks have alumina content extending upto 95% alumina and are mostly use for applications starting from 1500°C.These products are distinguished by their pure chemistry, high hot strength and excellent volume stability in service. Especially notable are bubble alumina based bricks.
