Title:
結晶成長炉における電極固着構造体
Document Type and Number:
Japanese Patent JP5258541
Kind Code:
B2
Abstract:
An electrode anchoring structure in a crystal-growing furnace includes at least one graphite electrode pillar, at least one metal electrode pillar, at least one anchoring base, and at least one locking nut, wherein the graphite electrode pillar is engaged with a nut base of the metal electrode pillar, and the at least one metal electrode pillar is, through the anchoring base, is secured to furnace wall. Therefore, the at least one graphite electrode pillar acts both as weight support and electrical-conducting electrode. Since the flange welded on furnace wall has a greater area exposed to the atmosphere, a desirable cooling effect can be achieved, and temperature drop can be expedited if water spray is performed. The anchoring base is provided with a resilient washer, such that a resilient force can be employed to adjust loading of each graphite electrode pillar in an axial direction.
