Lightweight Mullite Refractory Brick

Description:

    Hh lightweight mullite refractory bricks are made from good quality and superpure raw materials,with strictly classified fillings according to their grades.These fillings can form a uniform pore structure after burnt during the process of manufacture.Each grade of products has unique design to meet different thermal,physical and chomical demands.

Features:

   1.Low thermal conductivity

   2.Low heat capacity

   3.Low content of impurities

   4.High hot compressive strength

   5.Accurate size

   6.The bricks can be processed into special shapes

Application:

   The refractory linings of hot surfaces or backing heat-insulating layers of other refractory materials.The refractory linings or heat-insulating materials of the industrial furnaces in the petroleum or chemical industries,such as ,ethylene pyrolysis furnaces,tubular furnaces,reforming furnaces of synthetic ammonia,gas generators and high-temperature shuttle kilns,etc.
