Abstract

A continuous sintering furnace has an entrance-side deaerating chamber through which trays each with an material to be sintered being mounted thereon may pass, preheating, heating and cooling zones into which the trays are sequentially fed from the deaerating chamber, an exit-side deaerating chamber through which the trays having passed through the cooling zone may pass, a pusher for pushing the tray from the deaerating chamber to the preheating zone, a puller for pulling the tray from the cooling zone to the deaerating chamber, an intermediate puller for pulling the tray from the heating zone to the cooling zone, a vertically movable door between the deaerating chamber and the preheating zone, a vertically movable intermediate door adjacent to the door and arranged at an upstream end of the preheating zone in the direction of transportation of the trays, a vertically movable intermediate door between the heating and cooling zones and a vertically movable door between the cooling zone and the deaerating chamber. With the door being at a lowered position thereof for closing, heat input is suppressed to the cooling zone. Movement of the trays in the cooling zone is effected by the intermediate puller so as to decrease the number of trays needing to be pushed by the pusher.
