It is used for reclaiming WC cemented carbide via the zinc process. Designed as a twin-chamber horizontal vacuum furnace, the front chamber serves as the heating zone, which accommodates graphite crucibles containing the alloy and zinc. Once the zinc melts, the cemented carbide scrap is submerged for thermal modification. The rear chamber acts as the cooling chamber, housing the zinc recovery crucible. The graphite crucibles in the heating chamber and the cooling chamber are
