摘要:
A system and method for insulating an induction vacuum furnace is disclosed. An induction furnace for heating a workpiece includes a chamber, an insulation cylinder positioned within the chamber, and an induction coil positioned to surround at least a portion of the insulation cylinder. A susceptor is positioned within the insulation cylinder and inductively heated by the induction coil when a current is provided to the induction coil. An insulating jacket assembly including one of a carbide material and a refractory metal is positioned in a space between the insulating cylinder and the susceptor.

Die Erfindung betrifft eine mobile Schmelzeinrichtung zum Konsolidieren von kontaminiertem Schrott und ein entsprechendes Verfahren. Die Schmelzeinrichtung weist eine Tiegelkammer und eine Tiegelbasis auf. Der Tiegel ist im Betrieb auf der Tiegelbasis angeordnet und Tiegelbasis und Tiegelkammer bilden zusammen ein gasdichtes Ofengehäuse. Dadurch ist es möglich, das Verfahren unter Vakuum oder Schutzgas durchzuführen, so dass sogar reaktives Material konsolidiert werden kann. Die Schmelzeinrichtung kann ohne großen Aufwand auf- und abgebaut werden.

摘要:
An induction furnace for heating a workpiece includes a chamber and an induction coil to provide for heating of the workpiece when a current is provided thereto. A cooling manifold is positioned within the chamber and constructed so as to provide a controlled cooling of the workpiece. The cooling manifold includes a wall structure configured to define a hollow interior volume of the cooling manifold, a gas input formed in the wall structure and being connectable to tubing that provides cooling gas from an external source, and a plurality of gas ports formed in the wall structure so as to be spaced apart around a perimeter of the wall structure. Cooling gas received from the external source is passed through the hollow interior volume of the cooling manifold and exits the plurality of gas ports so as to provide a distributed and controlled gasflow across the workpiece.
