Abstract
An apparatus for producing single crystal silicon comprising: an induction heating coil that is disposed around the polycrystalline silicon rod for fusing the polycrystalline silicon rod; an exothermic ring that has a quartz-coated member covering the conductive member; a support member that supports the exothermic ring and passes through a wall of the housing in a rotatable manner; an operating device that rotates the support member and reciprocates the exothermic ring between a heating position where the exothermic ring is positioned close to the induction heating coil and a stand-by position where the exothermic ring is receded from the heating position; a sealing member that is provided between the wall of the housing and the support member and maintains the hermitic therebetween; and a cooling flow path that is formed in the support member and flows a cooling medium.
