Description of Mullite Insulating Brick:
Mullite bricks are high alumina refractories with mullite as the main crystal phase. Generally, the alumina content is between 65% and 75%, and the refractory of mullite brick is relatively high, reaching above 1790 ºC. The starting temperature of load softening is 1600 ~ 1700 ºC. Good thermal shock resistance. There are two kinds of sintered mullite bricks and fused mullite bricks.Standard size 230 x 114 x 65 mm or according to customer requirements.
Feature of Mullite Insulating Brick:
It has the advantages of high porosity, small bulk density, good insulation effect, and long service life. With high refractoriness, mullite insulation bricks can be directly exposed to flames. They have the characteristics of light weight, high strength, low thermal conductivity, good thermal shock resistance.For various industrial kilns, it is an important energy-saving, insulation, and refractory material.
1. Good integrity with furnace lining, long service life, easy operation, could be shaped freely
2. Product specification: standard form, normal standard, shaped and special shaped bricks.
3. Can be used in various kilns because of its cheapness and general tray package. Among all of the refractory materials, it is the most widely used.
