ABSTRACT:
An automated installation for punching and cleaning converter tuyeres for use in non-ferrous pyrometallurgy. The invention employs a travel unit fixed either to the converter housing permits movement of the punching unit relative to the tuyeres and, consequently, piercing of tuyeres at the converter. The unit consists of a punching rod slidable along the axis for introducing the punching end-piece of the punching rod into the tuyeres and a car securing the opposite end of the punching rod. The car resting on the rail is moved along by a driving unit. The drive mechanism of the travel unit has at least one power cylinder located transversally with respect to the rail, whereas on the extended end of the piston rod of this cylinder is a carriage with at least one pair of pull rods is mounted being coupled with the rod in an articulated way.
Still another embodiment of the invention consists in an application of only one pair of pull rods mounted on the both sides of the piston rod of the above mentioned cylinder in an articulated way slidable in a carriage in a plane perpendicular to the axis of the above mentioned power cylinder. One of pull rods is connected in an articulated way with the rail on the side of the above mentioned power cylinder opposite to the punching unit, while the other pull rod with is connected with the punching unit accommodating the working tool.
