Abstract
A top hat annealing furnace with pivoting features. The annealing furnace has an annealing understructure, an annealing hood, a heating hood and a cooling hood. The annealing understructure and the annealing hood are supported so that they can be tilted between an operating position and a loading position. The heating hood and the cooling hood are provided with doors, which can be closed when the furnace is in use, and opened when it cycle is completed. When the doors of either hood are open and the hood is oriented vertically, the hood can be moved horizontally relative to the annealing hood.
Claims18
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 90° 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).
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 all annealing hood (10), which can be placed in a sealing manner on the annealing 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 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 at least one door 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).
