Abstract:
A top hat furnace system for annealing metal coils (7), having an annealing understructure (1), which is seated on a furnace foundation and on which at least one metal coil (7) can be placed with its coiling axis vertical, and having an annealing hood (10), which can be placed in a sealing manner on the annealing in understructure (1) and over which a heating hood (11) or alternatively a cooling hood can be placed,wherein at least one arbor (6) extending normal to the base surface of the annealing understructure (1) is mounted on said annealing understructure, wherein the annealing understructure (1), including the annealing hood (10) and the metal coil or coils (7), is mounted in such a way as to be tiltable by 90Â° between a vertical and a horizontal position, wherein the annealing hood (10) can be placed on the annealing understructure (1) and removed from the latter in its horizontal position, wherein both the heating hood (11) and the cooling hood are provided laterally with opening and closing means for defining an opening through which the annealing hood (10) can pass, and wherein both the heating hood (11) and the cooling hood can be moved in a vertical position horizontally relative to the annealing hood (10).
