CA 70 High Alumina Refractory Cement For Rotary Kiln / RH / DH Kiln
Description:
1. Calcium aluminate refractory cement is also called bauxite
cement,high alumina cement,aluminate cement and calcium aluminate
cement.
2. Calcium aluminate refractory cement is made by high alumina
bauxite and limestone materials.
3. Calcium aluminate refractory cement is usually used for making
refractory concrete or refractory castable.
