Abstract

See full text

An induction furnace for heating a workpiece includes a chamber and an insulation cylinder positioned therein, with the insulation cylinder including a base cover movable between first and second positions, and the first position positioning the workpiece within a heating zone and the second position positioning the workpiece within a cooling zone. A translation system in the furnace includes a first member coupled to the base cover of the insulation cylinder and extending through a wall of the chamber, an actuator coupled to the first member, the actuator configured to translate the first member to move the base cover of the insulation cylinder between the first and second positions, and an expansion member encircling a portion of the first member and configured to hermetically seal an interior volume of the chamber from an environment volume external to the chamber.
