ABSTRACT:
A crucible furnace includes an ejector for removing the crucible from the furnace. The ejector consists of an ejector apparatus located below the floor of the furnace. A pressure transfer body in the shape of an inverted truncated cone is normally inserted in a truncated cone-shape opening in the furnace floor. The ejector acts upon the pressure transfer body to lift the body, as well as the crucible resting upon the body, out of the furnace. A hydraulic cylinder activates the ejector device.
