Abstract
A machine is provided for piercing a taphole for a shaft furnace for applying the piercing rod method. The machine comprises a mounting, with a support for supporting the rod at the front of the mounting, a sliding support for supporting the rod at the rear of the mounting and a clamp, mounted in a sliding manner on the mounting and designed for gripping the rod at any place between the front support and the rear support. A travel multiplier is connected between a jack and the clamp so that the clamp may be moved. Means for controlling the jack make it possible to move the clamp in a to-and-fro motion between a position (B) at the front of the mounting and a position (A) which is located at a distance L from the position (B).
