ABSTRACT:
A metallurgical furnace for the high temperature heating of heavy metal objects for subsequent operation, such as rolling or forging, has a work support for the pieces being heated comprised of water-cooled tubes and supports enclosed with sectional heat insulating tile enclosing the tubes where the sections of tile are immovably secured to the tubes by fasteners each having a tubular shank extending from a flanged head portion embedded in the refractory radially inward to the inner surface of the tile where it is welded to the exterior of the water-cooled tube to prevent relative movement between the tile and the tube under the heavy impacts to which the support is subjected and to more effectively cool the refractory tile immediately adjacent the fasteners.
