Refractory materials are widely used in the metallurgical industry, and engineering consumption accounts for about 60% to 70% of the total output. Therefore, the development of refractory materials is an important foundation for the metallurgical industry. However, precisely because the refractory materials are prepared at the time of preparation, the preparation process is relatively simple. Amorphous refractory materials commonly used in boiler structures generally consist of refractory aggregates, powders, mixtures, and binders. Therefore, many types of amorphous refractory materials have a wide range of applications.
Refractory plastics are made from refractory aggregates and powders, raw clay, chemical binders, and admixtures. After preparation, mixing, and extrusion into bricks, it has good plasticity after being packaged and stored for some time. Typically, discontinuous refractory plastics are mostly repaired.
Refractory ramming material is a material that can be formed by pneumatic sorting or manual ramming.
The refractory spray material is injection molded.
Refractory coatings are pump-cast with mud and mortar or applied by hand.
The refractory material is molded with projectors.
Fire-resistant pressed material formed by pressure devices such as mud pumps.
Refractory clay or refractory cement is the connecting material for building refractory bricks.
Refractory materials are classified mainly based on temperature (high, medium, and low-temperature types) and classification (fire resistance, wear resistance, alkali resistance, acid resistance, etc.). The technical requirements of refractory structures determine the performance of refractory materials.
