Used in industrial furnace lining, lining materials, high temperature insulation materials, etc.
The degassing box is made of high-strength castable through integral casting and sintering, with good thermal shock resistance.
Tubular filtration equipment is installed between CFF filtration equipment and rolling mill.
The filter box lining is made of qualified castable and produced under sintering. It has high temperature resistance, corrosion resistance and good thermal insulation.
Caster tips have the advantages of uniform molten aluminium flow, laminar flow, no blockage, and the same temperature in the caster tip outlet.
