Apparatus (1) for cooling an automobile component (20) by means of a gas, the apparatus comprising a cooling box (11) with a re-closeable opening (12) for receiving an automobile component (20) to be cooled, wherein at least one heat sink (13) is provided inside the cooling box (11) for cooling of the gas, and wherein the apparatus (10) includes at least one infra sound pulsator (2,3) arranged to provide an infra sound into said cooling box (11) to improve heat exchange of the gas both with a cooling surface of the at least one heat sink (13), and with the automobile component (20).

The present invention discloses a heating system for drill steel pipe billet, comprising a feedback device, a propulsion device, a positioning device, a heating device, a temperature measuring device and a conveying device. The distance d.sub.1 and d.sub.2 of three flamethrowers are controlled through the feedback device. The heating temperature of the flamethrowers is controlled by the oxygen distribution box and the gas distribution box. On the other hand, the present invention also provides a heating method for drill steel pipe billet, which adopts the rolling forming method of gradient flame heating, which realizes the control of the density of the rolled pieces, avoiding the internal defects of the drill steel caused by the same deformation of the traditional pipe billet after uniform heating, improving the quality of the drill steel, and prolonging the service life of the drill steel. The radial temperature of the drill steel pipe billet is accurately controlled through the feedback device. Flame heating with low cost is adopted. For drill steel pipe billets of different dimensions, only a set of flamethrowers corresponding to the dimensions needs to be designed, and other devices are universal components, which do not need to be replaced.

A continuous furnace for the heat treatment of steel sheets, such as hot forming and press hardening, wherein two zones with mutually different temperatures are formed in the furnace, and a separating wall is present between the two zones. A gap is present in the closed state between the steel sheet and the separating wall and a surface cooling nozzle is in the form of a tube, wherein the surface cooling nozzle has outlet openings pointing downwards in the vertical direction and the surface cooling nozzle is arranged in the direction towards a relatively cooler zone.

A facility with an annealing system including one or more (typically a plurality of) autonomous vehicles, e.g., shuttles, cars, etc., which autonomous vehicles each receive sheet metal coils, e.g., one, two, or more sheet metal coils, and move the sheet metal coils about the facility. The sheet metal coils generally include aluminum coils, though other sheet metal coils, such as brass, copper, steel, etc. coils, can be used without departing from the scope of the present disclosure. The annealing system also can include a stationary unit or component, or a plurality of stationary units, configured to dock with the autonomous vehicles to facilitate annealing of the coils on or within the autonomous vehicles.

There is a vacuum heat treatment apparatus comprising: a vacuum chamber; a stage disposed in the vacuum chamber and having a substrate placing surface on which a substrate is placed; a heater provided in the stage; a partition member configured to partition a part of an internal space of the vacuum chamber to form a gas processing space between itself and the substrate placing surface of the stage; and a gas supply configured to supply gas to the gas processing space.

A hot-forming line and a method for operating the hot-forming line is disclosed having a temperature-control station and a hot-forming and press-hardening tool. A linear conveyor system for conveying the metal blank or the formed steel-sheet products, respectively, through the hot-forming line is provided.

A helicoidal blade system is presented having an armature to facilitate bending of metal stock to form helicoidal blades. In one or more embodiments, the armature has an exterior surface that is generally conical in shape and includes a guide structure and an engagement track. The helicoidal blade system also includes drive coupler and motor that are operably coupled together. The drive coupler is configured to engage the engagement track of the conical armature and rotate the conical armature when the motor is operated. A blade metal feed apparatus is configured to feed the metal stock into the helical shaped guide structure as the conical armature is rotated. As the conical armature is rotated, the metal stock is bent around the armature within the helical shaped guide structure to form one or more helicoidal blades.

A thermal treatment furnace includes a thermal treatment chamber in which a thin metal sheet is continuously conveyed horizontally while being floated by air, in which the thermal treatment chamber includes a plurality of air injection nozzles and a plurality of mist spray nozzles that are arranged along a pass line of the thin metal sheet in the thermal treatment chamber, on a lower side and an upper side of the pass line and so as to be orthogonal to the pass line in a side view.

A device for aligning a metal blank for a temperature control system which has at least one temperature control unit for heating or cooling the metal blank includes at least two support rollers on which the metal blank can be placed and conveyed through the temperature control system by rotation of the support rollers in the throughput direction and within a conveying plane. The support rollers are arranged spaced apart in the throughput direction. The device further includes a first centering unit having at least one centering finger which is movably arranged within the conveying plane such that the centering finger is movable transversely to the throughput direction in order to align the metal blank in a predetermined orientation.

Provided is a heat treatment apparatus capable of more reliably conveying a workpiece along a desired conveyance path by a simple configuration.
