Products Description
High alumina refractory cement is made by high-quality bauxite and high-quality lime as raw materials, they are mixed into an appropriate amount of raw material according to a certain proportion. After sintering, the clinker with aluminate as the main component is obtained, and then ground into fine powder to make fire-resistant water Hard cementitious material, called refractory cement. The refractory degree of refractory cement is not less than 1580 degrees Celsius.
Product characteristics
CH Refractries manufactured high alumina refractory cement with very stable performance and has been exported to many countires. When exporting we packaged high alumina refractory cement with more than 4 layers bags to protect cement from moisture when shipping on the sea.
Application
High alumina refractory cement is mainly used for: preparing traditional medium and high cement castables, lightweight refractory castables, making refractory castable prefabricated blocks, refractory spray coatings, alkali-resistant castables, quick repair coatings, ordinary high-aluminum Production of quality castables and slag retaining balls, etc.
