Mullite Refractory Castable DYSEN Industrial

Product parameters:

Product features:

1. Suitable for linings of various industrial kilns: Lightweight mullite castables can be used as working linings or thermal insulation linings of industrial kilns, which can achieve high-temperature energy-saving effects.

2. High strength and small unit weight: Compared with ordinary low-cement castables, lightweight mullite castables can reduce the structural weight by more than 30% when used, avoiding safety hazards such as structural brick breakage and collapse.

3. Excellent thermal insulation performance: The lightweight mullite castable is made of high-quality porous mullite aggregate and used in conjunction with a variety of micro-powders and dispersants, which has low thermal conductivity and good thermal insulation effect. Compared with ordinary castables, lightweight mullite castables can reduce kiln heat loss by 25% to 35%, thus saving about 10% of fuel.

4. Convenient construction: Lightweight mullite castables can be cast as a whole on site or made into prefabricated parts of various shapes for combined installation, making construction simple and convenient.

Applications:

Used for tubular heating furnaces in the petrochemical industry, light diesel oil, ethane cracking furnace linings, atmospheric and vacuum furnaces, sulfur recovery devices, steam boilers, tortoise shell mesh insulation layers, single-layer insulation for both cylinders and pipes, and other industrial furnaces Furnace door, fire hole, observation hole door lining, etc. Mullite castables have the characteristics of high high-temperature structural strength, low high-temperature creep rate, small thermal expansion, good resistance to chemical erosion and excellent thermal shock stability.
