Abstract:
The continuous heat treatment furnace of the present invention is provided with at least one drying and binder-removing area where drying of the objects to be thermally treated and/or removal of binder are carried out and a firing area where the objects to be thermally treated is fired in succession from inlet side towards outlet side of the furnace, the objects to be thermally treated being subjected to drying and/or removal of binder while being transported through the drying and binder-removing area and thereafter being fired while being transported through the firing area, wherein the heat treatment furnace has at least two transporting mechanisms disposed along the transporting direction of the objects to be thermally treated as transporting mechanisms for transporting the objects to be thermally treated, the objects to be thermally treated are transported by different transporting mechanisms in the drying and binder-removing area and the firing area, respectively, and the transporting speed of each transporting mechanism is set so that the transporting speed in the drying and binder-removing area and the transporting speed in the firing area differ from each other.
