Product Description

Special Mullite Insulating Refractory Brick with Good Refractoriness
The Description:
The high alumina refractory material with mullite as the main crystalline phase is called mullite insulation brick. Generally, the alumina content is between 65% and 75%. In addition to mullite, the lower alumina content also contains a small amount of glass phase and cristobalite; Higher alumina content also contains a small amount of corundum. The product has low thermal conductivity and good thermal insulation effect; High refractoriness; High aluminum content makes it maintain good performance in reducing atmosphere. Hot state high compressive strength, the product can contact the flame, the application is very wide.

Product feature:

1, Low thermal conductivity, with good thermal insulation effect;

2, Mullite insulation brick low heat melt, due to low thermal conductivity, Mullite series light heat insulation brick accumulates little heat energy, energy saving effect is obvious in intermittent operation;

3, Low impurity content with very low iron box alkali metal oxide content, therefore, high refractoriness; High aluminum content makes it maintain good performance in reducing atmosphere.

4, Mullite insulation brick hot state high compressive strength;

5, The appearance of accurate dimensions, speed up the masonry speed, reduce the use of refractory mud, to ensure the strength and stability of the masonry, thereby extending the life of the lining;

6, Mullite insulation brick can be processed into special shapes. To reduce the number of bricks and joints.
