Light Weight Mullite Brick
Description
The light mullite brick uses plate corundum, high purity fused corundum as the main raw material, Using advanced superfine powder addition technology, After mixing, drying, molding, and then fired in a high temperature shuttle kiln. Widely used in residue gasifier, ammonia secondary converter, carbon black reaction furnace and other furnace equipment . The size, physical and chemical indicators and service life of the products are up to customers' requirements. Welcome to consult and discuss. We will achieve your satisfaction with quality products and services.
The advantages of light weight mullite brick are as follows:
1. The thermal conductivity is low, so only a small amount of thermal energy is accumulated. The energy saving effect is obvious in intermittent operation.
2. The impurity content is low. It has very low content of oxides such as iron-alkali metals, so it has high fire resistance, and high aluminum content makes it maintain good performance in reducing atmosphere.
3. It has good high temperature flexural strength and can effectively buffer the damage caused by thermal stress.
4, can be processed into a special shape to reduce the number of masonry blocks and joints.
5. The appearance size is accurate, easy to build, reduces the use of refractory mud, ensures the strength and stability of the masonry, thus prolongs the life of the lining.
The Technical Parameters Are As Follows:
