Process Description Smelting Home
During the smelting process the liquid level in the furnace can rise and fall. Unlike a tuyere, the lance can be raised and lowered automatically or manually so that its tip is always where it is required. The products of the smelting ISASMELT™ process are tapped from the bottom of the furnace through a water-cooled taphole.
