KERUI Bulk Sales High Alumina Refractory Cements High Temp Refractory Cement Price
High alumina cement is a high-performance cement product made from high-alumina clinker through sintering, grinding, and other processes. It has excellent properties such as high strength, high fire resistance, and high chemical resistance, making it an ideal material for various high-temperature and high-pressure applications.
High alumina cement is particularly suitable for refractory applications, including the lining of high-temperature kilns, furnaces, and other industrial equipment. It has exceptional fire resistance, withstanding temperatures up to 1600°C, and excellent thermal shock resistance, making it ideal for use in extreme heat environments.
In addition to its excellent fire resistance, High alumina cement also has a high compressive strength and excellent chemical resistance. It can withstand exposure to a wide range of chemicals, including acids and alkalis, making it highly resistant to corrosion and erosion.
High alumina cement is also easy to use and can be applied by spraying, casting, or troweling. Its fast setting time and high early strength help to reduce installation time and increase productivity.
At our company, we offer high-quality High alumina cement products that are specifically designed for refractory applications. Our products are manufactured to the highest standards and are rigorously tested to ensure their quality and performance. We also provide excellent technical support and customer service to ensure that our customers get the most out of our products.
