Document Type and Number:

WIPO Patent Application WO/2012/114779

Kind Code:

A1

Abstract:

Provided is an elevator-type thermal processing furnace with which the accumulation of decomposed binder gas in the form of tar on the surface of the elevator table and from the furnace main body to the bottom thereof is prevented. This elevator-type thermal processing furnace (1) has: a furnace main body (10); an aperture (26) formed in the bottom of the furnace main body (10); a heater (36) arranged in the interior of the furnace main body (10); and an elevator table (12) that approaches or moves away from the aperture (26) of the furnace main body (10) in order to introduce into the interior of the furnace main body (10) and to remove therefrom an object to be heat treated. In addition, a sealing part (28) is arranged in the gap between the bottom of the furnace main body (10) and the elevator table (12). Furthermore, gas discharge ports (52c) are constructed so as to blow the same type of gas as the atmospheric gas within the furnace main body (10) toward the side surfaces of the elevator table (12).
