JPS5579823A - Charging and discharging method for material in walking beam type heating furnace - Google Patents

Abstract

PURPOSE: To reduce equipment cost and maintenance cost, by transferring material from a charging table to the charging inlet of a furnace, or from inside of the furnace to a discharging table with contacting members by utilizing the drive of walking beams, hereby making pushers unnecessary.

CONSTITUTION: A walking beam 1 having rised and advanced to a position q is shown by I. The beam 1 then descends by the next motion to a position r. Hence an under track 6 moves along an inclined stand 12 from a point M to a point N. Because a chain 3 is pulled by a track 6, the material 9 is transferred to the furnace side by a distance L' with a claw 10 which is in contact with the material 9 placed on the charging table 2 as shown by II. Then the beam 1 returns to a point S, i.e., the rear end 13 of the upper part of the beam 1 moves backward to a point Y, then the beam 1 moves successively to a point p, the point q, so that it lifts the material 9 and moves the rear end 13 to a position Z, while the material 9 advances by a distance S'. Making another operation causes the material to advance by a distance S", and the rear end 13 comes to a position V.
