Calcium Aluminate Cement Application
The application industries of refractory cement include metallurgy, building materials, machinery, petrochemicals, ceramics, glass, boilers, electricity, steel, cement, etc. Mainly used in coke ovens, glass furnaces, blast furnace hot blast furnaces, and other industrial kilns.
Refractory cement is a high-quality binder that can be used to make high-performance low cement and high aluminum castables, refractory concrete, ramming materials, gunning materials, and other castables, or unshape block refractory materials used under high temperature, high pressure, and reducing conditions.Used for building or repairing various high-strength insulation or acid resistant kilns, etc.
