An oven system includes an oven chamber defined by side walls and a top wall. The oven chamber includes a slot formed in the top wall. A conveyor rail extends longitudinally along the slot at a position outside of the oven chamber. A conveyor hanger is coupled to and movable along the conveyor rail to support a material within the oven chamber. A first support bracket and a second support bracket each extend longitudinally along a length of the top wall of the oven chamber. The second support bracket is spaced from the first support bracket to define the slot that extends longitudinally along the top wall of the oven chamber. A closure mechanism is coupled to the first and second support brackets to inhibit heat from releasing out of the oven chamber.

A shell (10) acts as a transporting shoe for steel ingots, which are pushed through a preferably tubular induction furnace for inductive heating for the purpose of producing seamless tubes by the extrusion process. The shell (10) is formed in such a way that it partially reaches around the contour of the steel ingot to be heated. The shell is provided at one end leading in the pushing-through direction or transporting direction, with a shoulder (12), which extends at an angle to the transporting direction, against which the steel ingot rests in such a way that the pushed-through steel ingot takes the shell (10) along with it. A method for inductively heating steel ingots uses a shell (10) as described.

A vertical furnace for the continuous heat treatment of a metal strip, in particular for an electrical steel strip, as seen in the conveying direction of the metal strip, includes an inlet zone for the metal strip; a heating/holding zone with an annealing chamber for heating and holding the metal strip at a certain temperature; a first cooling zone for cooling the metal strip; and a deflection device, arranged downstream of the first cooling zone with at least one roller arrangement, for deflecting the metal strip in the direction of an outlet zone for the metal strip. At least one second cooling zone is arranged downstream of the deflection device with respect to the conveying direction.

A method of manufacturing a permanent magnet comprises a solution heat treatment. The solution heat treatment includes: performing a heat treatment at a temperature T.sub.ST; placing a cooling member including a first layer and a second layer on the first layer between the heater and the treatment object so that the first layer faces the treatment object; and transferring the treatment object together with the cooling member to the outside of a heating chamber, and cooling the treatment object until a temperature of the treatment object becomes a temperature lower than a temperature T.sub.ST200 C. In the step of cooling the treatment object, a cooling rate until the temperature of the treatment object becomes the temperature T.sub.ST200 C. is 5 C./s or more.

A load-moving system and a method for controlling the load-moving system for a heat treating furnace are described where the method includes detecting and transmitting signals and positions of the load-moving system as the load-moving system traverses a plurality of positions into, in, and out of the heat treating furnace. The signals being detected include one or more of: current, torque, or power used by the load-moving system at a determined position and/or time.

A closure mechanism to inhibit escape of heat from an oven chamber of a conveyor oven having a conveyor hanger. The closure mechanism includes a plurality of plates configured to couple to a first and second pluralities of connection tabs of a conveyor oven. Each of the plurality of plates include a connection portion, an angled portion configured to extend downward from the connection portion within a slot of the conveyor oven and an engagement portion extending downward from the angled portion to form an engagement surface.
