Unshaped Precast Block Compound Corundum Mulllite Refractory for Industry Furnace
The Description:
Refractory prefabricated parts are refractory components baked or cured after site construction, and are commonly used as building materials for high-temperature equipment. Compared with the traditional on-site masonry, the refractory prefabricated parts have excellent performance and better quality control. Usually, refractory preforms are cast or pressed in the field, then dried or sintered in the factory, and then transported to the site for installation.

Classification:
There are many kinds of refractory prefabricated parts, which can be divided into various types such as high temperature resistance, acid and alkali corrosion resistance, and wear resistance according to different uses. Among them, the high-temperature refractory prefabricated parts are the most widely used, such as tunnel kiln, oil refinery, metallurgical industry, glass industry, power industry, etc., need to use refractory prefabricated parts for heat insulation
The feature
They have good heat insulation, wear resistance, corrosion resistance and other characteristics in high temperature environment, which can effectively protect equipment, extend the service life of equipment, and reduce equipment maintenance costs.
