Lifting and turning unit for a melting and/or casting plant

摘要

A lifting and turning unit for a melting or casting plant. The lifting and turning unit for a deposit stand, preferably a table, for ingot molds of a vacuum melting and casting plant is provided. The unit consists of a tubular, vertically arranged lifter column that is axially movable with a hydraulic piston-cylinder unit and that has its upper end carrying the ingot mold table. A guide system composed of guide columns and of a yoke is provided. The guide columns serve for guiding the lifter column and for protecting the lifter column against twisting. The drive for the rotation of the rotatable ingot mold table is connected to the lifter column away from the harsh chamber environment. The unit provides an extremely low maintenance lifting and turing device wherein the longitudinal movements and the rotary movements can be executed separately from one another and thus allow for an exact positioning of the table.
