Abstract

Perfection improvements in percussion devices, which also perform temperature measurement and agitation, for an induction furnace under a controlled atmosphere and in particular to a vacuum, in which a crucible is placed in the bottom of which a graphite pellet is percussed to effect the casting of molten metals, characterized in that at the same time that an upright tube connected in a sealed manner to the upper part of said furnace by means of a bellows, adjusted by air jacks, is disposed above an induction furnace in a controlled atmosphere, and of joints, fitted between flanges, a hollow hammer animated by a motor by means of racks is slid in said vertical tube, a double seal is made between said vertical tube and the said hammer, especially by an oil seal and a gasket of lips, provided contactors to cause the establishment of controlled atmosphere and especially vacuum when said bellows were there in a low position, to stop the aforementioned hammer and, if necessary, to animate the latter, in this case provided with perforated discs, with an alternative movement that creates an agitation in said crucible, with means of measuring the temperature in said cited device being finally available. firing pin.
