    Refractory Fire Bricks are used for the internal linings of furnaces, kilns, reactors and other vessels for holding and transporting metal and slag. Also these are installed on fired heaters, hydrogen reformers, ammonia primary and secondary reformers, cracking furnaces, incinerators , utility boilers, catalytic cracking units, coke calciner , air heaters , ducting, stacks etc. These bricks have excellent volume stability and strength at high temperatures upto 1840 deg Celcius.

    fire bricks or Refractory Bricks is a block of Refractory Ceramic material used in lining Furnaces, Klins, FireBoxes, and FirePlaces. A refractory Brick is built primarily to withstand high temperature, but will also usually have a low Thermal Conductivity for greater energy efficiency. Usually dense firebricks are used in applications with extreme mechanical, chemical, or thermal stresses, such as the inside of a wood-fired kiln or a furnace, which is subject to abrasion from Wood, fluxing from ash or slag, and high temperatures. In other, less harsh situations, such as in an electric or Natural gas firedKlin, more porous bricks, commonly known as "kiln bricks" are a better choice. They are weaker, but they are much lighter, easier to form, and insulate far better than dense bricks. In any case, firebricks should not Spall, and their strength should hold up well during rapid temperature changes.

    Fire bricks havean  Aluminium Oxide content that can be as high as 50-80% (with correspondingly less silica)
