ABSTRACT:
A mechanical punching apparatus for punching tuyeres in which the position of punching rods is varied in a one action in correspondence to movement of the tuyere and in which the mechanical puncher, a carriage and a puncher tilting device are readily accessible for overhaul and maintenance. A mechanical puncher including punching rods assemblies is mounted on a carriage which moves on rails along the longitudinal direction of a converter. A link structure is arranged between the puncher and the carriage for tilting and moving the puncher with the movement being restricted along a predetermined locus having a center at the center of rotation of the converter. The link includes first and second sets of levers disposed between the carriage and puncher with a coupling rod pivotally coupled between levers.
