Abstract: In a method for processing used cathode material containing carbon, in particular used cathode troughs from aluminum production, the cathode material is put into a shaft furnace and, in order to gasify carbon, is subjected to a thermal treatment in the shaft furnace at a temperature above the ignition temperature of the carbon and above the evaporation temperature of toxic substances contained in the used cathode material. The reaction gases are conducted co-current with the carbon in a first longitudinal section of the shaft furnace and countercurrent to the carbon in a second longitudinal section of the shaft furnace. The reaction gases are drawn from a region of the shaft furnace having an enlarged cross-section between the longitudinal sections and are preferably subjected to an after-treatment.

Abstract: An apparatus for siliconizing carbon-containing workpieces has a chamber with an inlet, a siliconizing device inside, and an outlet. A transporting device has a fixed holding part that extends from the inlet to the siliconizing device and from there to the outlet, and a transporting part with two beams that can move in parallel. The holding and transporting parts have pairs of slots opposite one another with respect to a longitudinal axis L of the transporting device and configured for receiving a rod or the workpiece. The transporting part can be driven to execute a repeated cycle of movements that includes a lifting movement, an advancing movement and a lowering movement, in order to move rods that are resting on the holding part in a cyclical manner along the longitudinal axis L from the inlet to the siliconizing device and from there to the outlet.
