About Firebrick

Fire brick is a kind of shaped refractory material that is used to build all kinds of linings of furnace, stove and kiln at high temperature withstanding variety of physical shock and chemical erosion. Refractory brick are also called refractory blocks with all kinds of shapes can be customized according to customers’ special requirement based on Rongsheng Refractory professional engineers and advanced high heat refractory manufacturing process technology.

Classification of Firebrick

There are different types of firebricks:

  • Standard Firebrick
    Standard Firebrick is widely used in various kilns because of its low price and general manufacturing process. Standard Firebrick is fired in down draft kiln and tunnel kiln and its general sintering temperature is 1360~1480 ℃.
  • Medium Duty Firebrick
    Medium Duty Firebrick needs to fit into each. If the bricks appear curve or have a very bad shape, there will be a gap on the firing layer and also some spaces between the firebricks.
  • Super Duty Firebrick
    High Duty Firebrick contains high alumina content, which is designed and manufactured for super high heat and high duty applications such as furnaces to withdraw very strong physicochemical erosion.
