Definitions

  • This invention relates to a method of producing plated sheets, etc.
  • a' metal sheet to be plated and its plating sheet are tightly kept 5 with their edges in a frame of U-shaped cross section such as that disclosed in applicants prior Patent No. 2,064,684.
  • the invention eliminates these drawbacks and 80 prevents, or reduces to a minimum, the loss in temperature during handling of the package by placing the heat insulating means consisting of heat resisting steel, asbestos, etc., on the packet before it enters, or immediately after it leaves. a the furnace and removing the heat insulating means. prior to the passage of the package through the mill.
  • FIG. 1 is a fragmentary vertical section of a Q furnace showing a packet of the invention therein in vertical section;
  • Fig. 2 is a vertical section of the packet of the invention with two insulating sheets applied thereto; and 4
  • Fig. 3 is a diagrammatic end elevationof a rolling mill showing a packet of the invention about to enter the same, said packet being shown in vertical section.
  • the reference character a designates a metal core sheet and b metal plating sheets applied to the flat faces of the core sheet a.
  • a continuousframe c which is U-shaped in cross sec- 6 tion is applied to marginal portions of the assembled core and plating sheets to clamp the same together and form a packet.
  • the frame 0 shown may be the same as that disclosed in my prior Patent No. 2,064,684 of Dec. 15, 1936, or v may be any other suitable frame.
  • Insulating sheets d,d are applied to the packet to prevent heat loss after the packet is removed from the furnace.
  • Oxidation gases can be prevented from entering between the plating sheet and the core sheet 1. by constructing for instance the edges of the heat insulating means in such manner that they fully cover the sides of the packet.- If the latter is fitted with a U-shaped frame, the insulating means will rest on the latter without, however, 16 being held thereto to permit the development of an air cushion between the insulating means and the plating sheet, which will prevent them from being welded together and make possible also easy removal of the insulating means for further use.
  • Another advantage afforded by the detachable arrangement of the heat insulating means on the plating sheet or frame is that the plating sheet may be quite thin, since the insulating means I, does not pass through the mill.
  • the insulating sheets are shown applied to packet while the same is in the furnace. However, it is obvious that they can be applied, as More said, immediately. after the packet has been re- 8 i moved from the furnace.
  • a method of producing plated metal sheets comprising covering at least one-flat surface of a core sheet with a sheet of plating material, I binding said sheets together with a marginal frame to form a packet and exclude the entryof oxidizing gases between said sheets, heating said packet in a furnace to. a welding temperature, re-
  • a method of producing plated metal sheets comprising covering at least one flat surface of a core sheet with a sheet of plating material, bindg. ing said sheets together with a marginal frame to form a packet, providing an uninterrupted marginalbead around said packet and excluding the entry of oxidizing gases between said sheets,
