摘要： The description herein discloses a heat treatment furnace that performs heat treatment efficiently on a treatment-target object conveyed on a conveying path defined by a plurality of guide rollers. This heat treatment furnace includes a furnace body, a conveyor device configured to convey a treatment-target object from a conveying inlet to a conveying outlet through a treatment chamber, a plurality of guide rollers disposed in the treatment chamber, and a heating device disposed in the treatment chamber and configured to heat the treatment-target object. The heating device includes first heaters, each of which is disposed inside and/or near its corresponding one of the plurality of guide rollers and configured to heat the treatment-target object. The heating device further includes second heaters each disposed on the conveying path of the treatment-target object near an intermediate position between its corresponding guide rollers that are adjacent in a conveying direction and configured to heat the treatment-target object. The second heaters are each a heater configured to emit electromagnetic waves in an infrared region.

摘要： An infrared heater 10 includes a heating element 40 that emits infrared radiation when heated and that is capable of absorbing infrared radiation in a predetermined reflection wavelength range, and a filter unit 50 that is disposed so as to be separated by a first space 47, which is open to an outside space, from the heating element 40. The filter unit 50 includes one or more transmission layers (a first transmission layer 51) that transmit at least a part of the infrared radiation from the heating element 40, and a reflective section (the first transmission layer 51) that reflects infrared radiation in the reflection wavelength range toward the heating element 40.

摘要： A low-temperature drying apparatus 10 includes a furnace body 12, a sheet 20, an infrared light transmitting plate 30, a supply device 40, a discharge device 45, and infrared heaters 50. The sheet 20 holds a coating film 22, which is an object to be dried, so that the coating film 22 is placed in the furnace body 12. The infrared light transmitting plate 30 is provided on a surface of the furnace body 12 that faces the sheet 20. The supply device 40 and the discharge device 45 generate a cooling flow in a space between the coating film 22 and the infrared light transmitting plate 30. The infrared heaters 50 are disposed to face the infrared light transmitting plate 30 in the open space OP outside the furnace body 12.
