HEATING FURNACE

PURPOSE:To provide a two stories type heating furnace by which the rationalization of plant layout and the saving of heat energy are obtained by so constituting its upper heating chamber that the objects to be heated transferred in a transverse direction are transferred to a lower heating chamber in the end part of said chamber and are tranferred in the transverse direction opposite to the above-described direction. CONSTITUTION:Objects 6 to be heated 6 are carried 7 into the upper heating chamber 3 of a furnace 1, and are placed on a horizontal wall 2 by a pusher 8. Next, the heated objects 6' are similarly placed on the wall 2 and the objects 6 are pushed by the objects 6' and are transferred toward the right (arrow f). The objects 6 are placed on a mechanism 9 of carrying said objects from the end on the side opposite to a charging roll 7 to a lower heating chamber 4 and are lowered downward (arrow n) and are conveyed into the chamber 4. Next, the objects 6 conveyed into the chamber 4 are placed on a walking beam 13 from the arm 11 of the mechanism 9 and are transferred to the right (arrow g), then the objects 6 are extracted to the outside of the furnace 1 from the opposite end of the mechanism 9. This heating furnace can make the furnace length shorter than that in the prior art and reduce installation area.
