Introduction of Mullite Refractory Brick Types and Characteristics
Release time:
Dec 13,2023
Mullite refractory bricks are made of synthetic mullite, according to the specific gravity of the product requirements, adding organic compound fillers, vacuum extrusion molding, high temperature sintering synthesis of lightweight mullite products. With its characteristics of light weight and excellent thermal insulation performance, mullite lightweight refractory bricks are widely used in the hot surface refractory lining or insulation layer of a variety of thermal equipment, creating conditions for improving the energy efficiency of the equipment.

With its characteristics of light weight and excellent thermal insulation performance, mullite lightweight refractory bricks are widely used in the hot surface refractory lining or insulation layer of a variety of thermal equipment, creating conditions for improving the energy efficiency of the equipment.
The mullite lightweight refractory brick is a high alumina refractory material with mullite main crystal phase, and the general alumina content is between 65%-75%. The refractory temperature of mullite lightweight refractory brick can reach above 1790 ℃. The starting temperature of load softening is 1600-1700 ℃. Good thermal shock resistance.
Mullite lightweight refractory brick features
1. Low thermal conductivity, with good heat insulation effect;
2. Low hot melt, due to low thermal conductivity, mullite series lightweight thermal insulation bricks accumulate very little heat energy, and the energy saving effect is obvious in intermittent operation;
3. Low impurity content has very low iron box alkali metal oxide content, therefore, high refractoriness; high aluminum content makes it still maintain good performance in reducing atmosphere;
4. High compressive strength in hot state;
5. Appearance size, speed up the masonry speed, reduce the amount of refractory mud, ensure the strength and stability of the masonry, thereby extending the life of the lining;
6. Can be processed into special shapes. To reduce the number of brickwork and masonry joints.
