Abstract

A machine and method is provided for piercing a taphole for a shaft furnace. The machine comprises a mounting, with a support installed on the mounting so as to support a rod at the front of the mounting, a rear support which can move on the mounting and is provided with means for being coupled to the rear end of the rod and a clamp mounted in a sliding manner on the mounting and designed to grip the rod at any place between the front support and the rear support. A powerful rotary motor installed at the rear of the mounting drives an endless chain installed axially in the mounting. A clamp attached to the endless chain moves during the insertion of the rod into the taphole clay by reversal of the direction of rotation of the motor 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).
