Beschreibung
Zusammenfassung:	In an apparatus for punching the tuyeres of a converter for smelting of copper or nickel, the apparatus including a carrier frame supported by wheels and which is capable of moving on the working platform located adjacent to the converter, the carrier frame mounting a plurality of punch rods which can reciprocatingly extend into respective tuyeres to remove deposits therein. An electric motor is employed to drive the carrier frame and an electrical control system controls the operation of the electric motor and thus the movement of the carrier frame so that the correct positioning of the punch rods with respect to the tuyeres on a converter can be automatically achieved.
