Cast Zirconium Corundum Linings

Recyclable ceramic with high abrasion and temperature resistance. KALCOR® is a combination of alumina, zirconia, and silica that is melted at 3,600°F and then cast in tiles of various types, cylinders, and custom-designed shapes. The pre-engineered, cast linings withstand extreme abrasion and moderate impact and have a low thermal conductivity.

Zirkonkorund KALCOR

The cast and alternatively sintered material KALCOR has proven its worth in the lining of plant components in which high temperatures and temperature changes occur in addition to extreme wear and tear, e.g. in chutes for hot sinter or clinker, in hot gas lines, or in dedusting cyclones and separators.
