    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 hot exhaust gas generated in the furnace into the shaft. The water cooled finger is formed of a pair of side faces, an upper plate and lower plate. The upper plate is fixed to an upper part of both of side face portions. The lower plate is fixed to a lower part of both of side face portions. The water cooled finger is formed to be hollow as a whole. It satisfies at least one of the conditions of (A) a thickness of the upper plate is larger than that of said lower plate, (B) the lower plate is formed with R-bending processed portions at both ends thereof, and (C) the lower plate is curved outside.
