2. Description of the Related Art Conventionally, when heat-treating various industrial materials or products, a batch type heating furnace capable of batch-processing a large number of articles has been generally used. When there is a heat treatment process in the line, batch processing is performed at the position of the heating furnace, so the line is cut off and production stagnation occurs, resulting in reduced production efficiency and inventory. There is an increasing number of cases in which a transfer heating furnace that can perform heat treatment is used.

However, in the conventional transfer heating furnace, since the conveyor is passed through the heating chamber and the object to be heated is transferred while being conveyed by the conveyor, the entire conveyor is exposed to a high temperature to cause oxidation or thermal deformation. There is a drawback in that rusting, dusting, and the like occur, and loosening of parts and malfunctioning of the parts cause frequent adjustments. Moreover, since it generates dust, it cannot be used in a clean room.

The air in the heating chamber 14 is heated by the heater 13
It is heated by the convection and flows out into the thermal buffer chamber 15 from the groove hole 18. The hot air that has flowed out stays in the upper portion of the thermal buffer chamber 15 on the side of the heating chamber 14 and the portion is heated to the temperature inside the heating chamber. Keep high temperature close to. Therefore, the heating chamber 14 passes through the slot 18.
Even if air flows between the heat buffer chamber 15 and the heat buffer chamber 15, the temperature of the air inside the heat chamber 14 hardly changes because the air flowing from the heat buffer chamber 15 into the heating chamber 14 has a high temperature. It will be kept constant and uniform.
