High Temp Refractory Cement is a hydraulic binder designed specifically for high-temperature applications. It is produced by calcining high-grade bauxite and limestone, which results in a product with excellent early strength, high refractoriness, and strong bonding properties. The primary mineral components of this cement, CA and CA2, provide superior heat resistance and make it ideal for use in harsh industrial environments.
This cement has a high resistance to thermal shock, making it suitable for use in high-temperature processes. It is commonly used as a binder for various refractory materials like castables, mortars, gunning mixes, and precast refractory shapes. This versatility makes it perfect for furnace construction, kiln repair, and industrial maintenance.
Xintai offers a wide range of grades, including CA50, CA60, CA70, and CA80, each designed to meet different temperature and strength requirements. With its stable performance and customizable options, this product is widely used in industries such as steel, cement, glass, ceramics, petrochemical, non-ferrous, and power generation.
