Here are some of the most common uses of refractory firebricks:

  1. Furnace linings Refractory firebricks are commonly used to line the interior of furnaces and kilns, providing a protective barrier between the hot gases and the surrounding walls. This helps to keep the heat contained and prevents the surrounding walls from becoming damaged or destroyed.
  2.  Insulation Refractory firebricks are also used in insulation applications. They are a popular choice for insulating walls, floors, and ceilings of industrial buildings, as they are able to withstand the high temperatures and provide excellent insulation.
  3. Fireplaces Refractory firebricks are often used in the construction of fireplaces, as they are able to withstand the heat of the fire without cracking or crumbling.
  4. Boilers Refractory firebricks are also used in the construction of boilers, as they are able to withstand the extreme temperatures and pressures generated.
