Product description of Alumina Ramming Mass
Alumina ramming material is an amorphous refractory made of bauxite clinker as aggregate and powder. It is constructed by manual or mechanical compaction, and then heated to form a lining to resist the corrosion of slag.
Alumina Ramming Mass Features
Good thermal shock resistance.
High temperature resistance.
High softening temperature under load.
Good slag erosion resistance.
