Product details

Chamotte insulation brick Al2O3 content is generally more than 40%, Fe2O3 content is less than 2.0 ~ 3.0%.

Clinker is mixed is around 65% to 85%, and combined clay is about 35% to 15%.

The pulverized binding clay and the ground clinker are mixed with the clinker and then mixed with the granulated clinker to form a semi-dry clay material.

The mixture is compacted at a high pressure and fired at about 1400 ° C, and the performance is relatively good. Chamotte insulation brick are weakly acidic at high temperatures.

Features and Application

Characteristics:

  • High strength
  • Good thermal stability
  • Small change of reheating line
  • Small thermal conductivity

Application:

Chamotte lightweight insulation brick can be used as hot surface refractories or other refractory materials to support insulation layer. It is mainly used for melting furnaces, kilns, flues, refineries, heaters, regenerators, gas furnaces and pipes, soaking Furnaces, annealing furnaces, reaction chambers and other industrial equipment.
