ABSTRACT:
A heating apparatus having doors mounted on the inlet and outlet of a furnace body to cover them and at least one additional door disposed in an intermediate portion of the furnace body to divide it into compartment furnace chambers forming a preheating chamber, a heating chamber and/or a warmth-keeping chamber, from the inlet side to the outlet side. A hot air circulating device is disposed in each of the compartment furnace chambers in a manner such that areas close to each door are much heated. When a material to be heated is charged from the preheating chamber, outer air is shut off from the heating chamber, and when the material to be heated is delivered into the heating chamber, outer air is shut off from the preheating chamber. When the material is shifted from the heating chamber to the warmth-keeping chamber or is discharged to the outside from the warmth-keeping chamber, outer air is shut off in the same manner as above.
