INSULATION APPARATUS

摘要

An insulation apparatus such as a CZ modular insulation pack for CZ-style mono-crystal pulling equipment is provided for use in the production of silicon, sapphire and other crystal materials. The apparatus may have a tubular heat shield with a generally cylindrical circumferential surface. The apparatus may include more than two fiber board segments arranged in side-by-side relation to form a continuous annular ring around the heat shield. The insulation apparatus may include two handles movable between a retracted position and an extended position relative to the heat shield.
