IPC: C22B21/00
Filed: 1992-01-24
Abstract: PURPOSE:To prevent heating of a rake arm by radiation at the time when it projects behind a support, by forming the rake arm in the shape of a shaft piercing through the support, by extending it by making it move forward, and by contracting it by making it move backward. CONSTITUTION:A support 3 which makes a rake arm 5 for aluminum oxide ashes shake and move in extension and contraction automatically is mounted on a base 1. The rake arm 5 is formed in the shape of a shaft piercing through the support 3, and the support 3 is provided with a forward-backward motion driving device for making the rake arm 5 move forward and backward and is so constructed that the rake arm 5 is made to move backward while projecting behind the support 3. Since the rake arm 5 projects behind the support 3 at the time of the backward motion by the operation of moving the rake arm 5 forward and backward and a radiant heat from a dissolving furnace 7 is intercepted by the support 3, a heat is radiated from the rake arm 5 by cooling of the rear part and heat conduction to the rear part. By repetition of the extension and contraction by a raking operation, therefore, the rake arm 5 is kept within a temperature of heat resistance.
