Directional Solidification Furnace Having Movable Insulation System

摘要

A directional solidification furnace is disclosed that includes one or more movable insulating members disposed adjacent sides of the crucible. In a first position, the insulating members restrict the flow of heat away from the sides of the crucible. In a second position, the insulating members do not appreciably restrict the flow of heat away from the sides of the crucible. An actuating system is used to move the insulating members between the first position and the second position.
