Fluid Tight Metallic Heat Transferring Box, Shield Or Hood Patents (Class 432/254.1)
  • Patent number: 6655956
    Abstract: A support frame for metal coils, which are stacked on top of each other for a heat treatment by means of a hot, gaseous medium, especially in bell-type annealing furnaces, has devices on the support frame for guiding the flow of the medium through the coils. The support frame is a framework constructed of I-sections. The end surfaces of the coils are supported on the flanges of the framework I-sections. The webs of the framework I-sections are provided with holes, which serve for guiding the flow of medium.

  • Patent number: 6655955
    Abstract: A coolable arched roof for a high-temperature melting furnace having a furnace interior. At least the following layers are present on that side of a layer of refractory bricks, which is remote from the furnace interior: a sealing layer, which is used to seal the furnace interior against the leakage or penetration of gas; an insulation layer having a thermally insulating action; and a cooling layer, which is designed to carry a cooling fluid. The arrangement of layers results in an increased gastightness and prevents premature aging of the refractory bricks.

  • Patent number: 6612835
    Abstract: A high-temperature, non-catalytic, infrared heater is formed within a housing having a bottom and at least one side lined with a refractory material. The burner includes a burner surface area and is positioned within the housing. A re-radiating surface is positioned above the burner and comprises a mesh having a re-radiating surface area greater than the burner surface area with the re-radiating surface operating between approximately 400° F. and 2200° F.
