Outstanding Durability and High-Performance Refractory Castable for Glass Furnaces
High-strength refractory castables are crucial materials in high-temperature applications like glass and regenerative furnaces. They are designed to protect the furnace structure and extend the service life of the equipment. These castables are known for their remarkable strength, resistance to wear, ability to withstand slag and erosion, ease of use, and their ability to provide long-lasting performance. They are typically used for installing low porosity clay bricks, high-aluminum bricks, mullite bricks, and corundum mullite bricks.
