Water cooled finger for pre-heater of furnace top |
摘要 |
A water cooled finger for a pre-heater of a furnace top holds metal materials of a required amount in a shaft installed at the furnace top for pre-heating metal materials by introducing exhaust gas at high temperature generated in the furnace into the shaft. The water cooled finger is formed of a pair of side aces, an upper plate and a lower plate. The upper plate is fixed to an upper plate of both of the side face portions. The lower plate is fixed to a lower plate of both of the side face portions. The water cooled finger is formed to be hollow as a whole by the side face, the upper plate and the lower plate. The water cooled finger satisfies at least one of the conditions of (A) a thickness of the upper plate is thicker than that of said lower plate, (B) the lower plate is formed to be R-bending processed portions at both ends thereof, and(C) the lower plate is curved outside.
