ABSTRACT:
A charging appliance for melting units that work under vacuum or under protective gas atmosphere includes a charging shovel, for holding charging stock, attached to a carriage which transports the charging stock to an advanced position inside the melting unit. The charging appliance further includes an ejector that holds the charging stock in the advanced position while the charging shovel is being retracted, resulting in the charging stock being deposited in the melting unit. The rolling carriage which transports the charging stock runs along a rail set. The rail set is movable via lifting cylinders. By selective displacement of two lifting cylinders, the elevation and angle of tilt of the rail set can be adjusted. Accordingly, the charging shovel can be maneuvered in a wide variation of positions inside the melting chamber. The charging appliance can be quickly and accurately adapted for use to a particular melting unit.
