  • Patent number: 10555641
    Abstract: The grill of the present disclosure provides multiple heating zones within a front-to-back direction of each cooking platen. Each cooking zone has a heating element associated therewith. The heating elements can be independently controlled, so that each of the heating zones can be operated at a different temperature if necessary. A controller can monitor and adjust the heat output of each element with a temperature probe that measures the temperature of the surface of the grill plate. One or more of the heating elements can be a gas burner. Electrical heating elements may also be used.

  • Patent number: 9745642
    Abstract: A method for heat treating a metal tube or pipe is provided to perform heat treatment in such a manner that metal tubes or pipes (1) to be accommodated in a heat treatment furnace are laid down on a plurality of cross beams (22) arranged along a longitudinal direction of the metal tubes or pipes with the distance between adjacent cross beams being in a range of 200 to 2500 mm. This makes it possible to inhibit bending and scratches of the metal tubes or pipes without causing discoloration and deterioration of the manufacturing efficiency for the metal tubes or pipes. When the metal tubes or pipes (1) are laid down on the cross beams (22), spacers may be interposed between the metal tubes or pipes (1) and the cross beams (22) on which they are laid down.

    Abstract: In a heating furnace 10 where elongate workpieces fed into the heating furnace are sequentially transferred on fixed beams by walking beams from an inlet area to an outlet area, concaves to retain the workpieces are formed at least on the walking beams. A concave in the inlet area for heating the workpieces is increased in width in a transfer direction, while a concave in the outlet area where the heated workpieces are wholly heated to a uniform temperature and retained in position is formed in a corrugated configuration. Despite curving of an elongate workpiece being heat treated as transferred by walking beams in a direction crossing a longitudinal direction of the workpiece, this ensures that the curved workpiece is properly transferred and adequately corrected for the curving.

An actuator for moving the compression plate is preferably automatically controlled by a computerized control system. The susceptors together form a tunnel through which pusher plates travel and have overlapping joints which seal against the escape of gasses and allow for a degree of susceptor contraction without forming a gap therebetween even in the absence of compression of the susceptors.

The containers are supported on respective holders of the conveyor, which prevent the containers from contacting one another. Preferably, the holders support the containers loosely, to enable the containers to wobble relative to the holders under the influence of oven air currents and conveyor vibration. The holders thus do not make contact with any given point on their respective containers for a time period that is sufficient to enable the holders to draw enough heat away from the container to adversely affect the foaming operation. The containers are conveyed in single file, along a serpentine path through the oven.

  • Publication number: 20010047979
    Abstract: A method is disclosed for speeding workpiece thoughput in low pressure, high temperature semiconductor processing reactor. The method includes loading a workpiece into a chamber at atmospheric pressure, bringing the chamber down to an intermediate pressure, and heating the wafer while under the intermediate pressure. The chamber is then pumped down to the operating pressure. The preferred embodiments involve single wafer plasma ashers, where a wafer is loaded onto lift pins at a position above a wafer chuck, the pressure is rapidly pumped down to about 40 Torr by rapidly opening and closing an isolation valve, and the wafer is simultaneously lowered to the heated chuck. Alternatively, the wafer can be pre-processed to remove an implanted photoresist crust at a first temperature and the chamber then backfilled to about 40 Torr for further heating to close to the chuck temperature. At 40 Torr, the heat transfer from the chuck to the wafer is relatively fast, but still slow enough to avoid thermal shock.

  • Patent number: 6164961
    Abstract: A vertical conveying apparatus is used particularly advantageously in a vertical continuous furnace, for example, in semiconductor production. Since rubbing contacts are avoided and there is thus barely any wear, continuous furnaces provided therewith are particularly suitable for the sensitive semiconductor products and production processes. Since no lateral guides are necessary for the specially designed carriers in the case of relatively small and average stack heights, there is no rubbing contact in the furnace region either, and wear is thus completely avoided. Furthermore, the invention is distinguished by its mechanical simplicity, which has advantages, in particular as far as durability and maintenance are concerned. The absence of retaining or transporting beams in the furnace region makes it possible to achieve a wide variety of different temperature zones over the vertical height of the stack.

  • Patent number: 5816798
    Abstract: A conveying apparatus for a continuous furnace comprises at least one conveying-beam pair and at least one retaining-beam pair, which are located opposite one another in each case with the conveyable object between them, and which makes it possible to choose virtually any conveying direction, in particular a vertical one. By guiding the conveying beams in opposite directions along suitable curved paths, it may be ensured that abrasive contact does not occur between the objects which are to be conveyed and the retaining beams, on the one hand, and the conveying beams, on the other hand. The avoidance of abrasive contact means that there is virtually no wear during the transportation of the objects which are to be conveyed, with the result that it is possible to maintain clean conditions, as are frequently required in the electronics and semiconductor industry.

  • Patent number: 5704783
    Abstract: A walking hearth furnace comprising fixed and walking hearths (1 to 3 respectively 4,5) on the refractory lining of which the work (6) is placed. Slanted surfaces are worked into the refractory lining forming depressions (15) and causing the work to be heated from underneath. The pieces of work are arranged in such a manner that spaces form between them, through which the heat from above can act on the slanted surfaces. Furthermore, the slanted surfaces serve to remove the scale both through the slots between the hearths and through scale chutes (16) which lead downwards out of the depressions (15) and operate in conjunction with scale removal devices (22).

  • Patent number: 5490315
    Abstract: In the continuous manufacture of hot strip material, slabs are produced by a pair of continuous casters and heated to a rolling temperature in a bi-level roller hearth furnace. Hot slabs are discharged from the bi-level furnace alternately from its upper and lower roller hearths. The slabs are then scarfed to clean oxide scale from both sides and to heat the slabs to a temperature of about 2300.degree. F. The scarfed ends of adjacent slabs are overlapped and passed through a two high slab mill welder wherein the overlapped ends are joined together. The joined slabs are thereafter finish rolled to strip gauge in a continuous multi-stand hot strip mill.
