    摘要： A high temperature conveyor belt is provided having a non-metallic conveying surface which will not scratch, abrade or otherwise mar the surface of a product being carried on the belt through a furnace and which will not contaminate the product. In one embodiment, the conveyor comprises a high temperature fabric belt attached to a metal belt which may be a conventional woven metal conveyor belt. In another embodiment, the conveyor is composed of a non-metallic high temperature strand which is woven or threaded through a metal belt to provide a non-metallic conveying surface. In a further embodiment, the non-metallic product support elements are coupled to roller chains at each side of the furnace chamber and which are cooperative with a drive mechanism to transport the conveyor through the furnace. The roller chains can be located outside of the furnace chamber to avoid exposure to the high temperature of the furnace chamber.

    摘要： Methods and systems (10) for plasma-assisted nitrogen surface-treatments are provided. The method can include subjecting a gas (24) to electromagnetic radiation (26) in the presence of a plasma catalyst (100, 120, 140) to initiate a plasma containing nitrogen. The surface region of an object can be exposed to the plasma for a period of time sufficient to transfer at least some of the nitrogen from the plasma to the object through the surface region.

    摘要： The present invention provides a system and method for binder removal and sintering of materials such as ceramic materials and products, LTCC intervals, solid oxide fuel cells and powder metals. A combination of microwave and convection/radiation heating is employed for binder removal and sintering. Preferably, the microwave heating is accomplished using a variable or multi-frequency microwave source. A gas atmosphere is provided in the furnace chamber by one or more eductors which produces a high volume gas circulation in the furnace chamber to achieve a highly uniform gas environment and temperature. The process in accordance with the invention controls the heating cycle, the heat sources and thermal profile depending upon the composition of the particular material being processed. The thermal processing can be accomplished in a batch furnace in which a product is loaded for processing and unloaded after processing. The invention can also be practiced in a continuous process wherein the product is conveyed between furnace sections or chambers of a furnace.

    摘要： An infrared furnace system provides for adjusting the amount of time a workpiece spends in a respective section of the furnace while at the same time minimizing the footprint, i.e., the amount of floor space that the furnace uses. Various embodiments allow for optimizing the required thermal duration of each section which then also optimizes the heating and/or cooling profile within each section. Transfer conveyors are provided to transfer a workpiece from one conveyor operating at a first speed to a second conveyor operating at a second speed, different from the first speed in order to prevent damage to the workpiece. Rollers are provided to support the workpiece and to maintain a proper orientation. A heating lamp support assembly provides power to the lamp and facilitates exchange and replacement of the lamp. An air delivery system provides process gas maintained at the correct temperature. An exhaust system provides air flow with improved turnover and reduced noise considerations. Infrared heating lamps are cooled by providing gas flow across the end terminals. The wavelength of light emitted by the heating lamps is adjusting by controlling parameters of the process gas being introduced into a section of the furnace.
