A strip flotation furnace for controlling the temperature of a metal strip has a flotation nozzle bar extending through the furnace transversely to a strip running direction of the strip. The flotation nozzle bar has two opposing first flotation nozzle rows spaced apart by a central region of the flotation nozzle bar. The rows are set up so that corresponding flotation nozzle jets, with a directional component toward the central region, can be generated to provide pressure cushioning for metal strip guiding. A temperature-control nozzle bar extends transversely to and is spaced apart from the flotation nozzle bar along the strip running direction. The temperature-control nozzle bar has two additional opposing temperature-control nozzle rows spaced apart by an additional temperature-control nozzle bar central region. These rows are set up so that corresponding temperature-control nozzle jets, with a directional component opposite to the additional central region, can be generated.

The invention relates to a device for continuous treatment of a metal strip (1), in particular a metal strip consisting of aluminum or an aluminum alloy, or consisting of a non-ferrous metal or a non-ferrous metal alloy, said device comprising at least one temperature control device (2) through which the metal strip (1) is guided in a floating manner, and comprising at least one strip position regulation unit (7), by means of which the position of the metal strip (1) can be controlled or regulated on the belt movement plane (E) and transversely to the strip running direction (B), wherein the temperature control device (2) has at least one entry-side heating section (3) and an exit-side cooling section (4). The invention is characterised in that the strip position regulation unit (7) that works in a contactless manner has at least one contactless strip position detection element (12) and at least one linear motor (13) and is arranged within the heating section (3) or between the heating section (3) and the cooling section (4).

A nozzle system for a band floating system for floatingly guiding a band-shaped material having a nozzle body having a front edge area and a rear edge area opposite to the front edge area, a front gas nozzle arrangement arranged at the front edge area, a rear gas nozzle arrangement arranged at the rear edge area, and a nozzle arrangement arranged, in the conveying direction, in front of the front gas nozzle arrangement and/or behind the rear gas nozzle arrangement such that a liquid fluid is flowable in a fluid jet into a nozzle floating field in the direction towards a band running plane for temperature-controlling the band-shaped material.

The present invention relates to a nozzle system for a band floating system for floatingly guiding a band-shaped material. A nozzle body, which has, along a conveying direction of the band-shaped material, which is conveyable within a band running plane, a front edge area and a rear edge area opposite to the front edge area. A front gas nozzle arrangement is arranged at the front edge area such that a front gas jet is flowable in the direction towards the band running plane for forming a nozzle floating field for the band-shaped material. A rear gas nozzle arrangement is arranged at the rear edge area such that a rear gas jet is flowable in the direction towards the band running plane for forming the nozzle floating field for the band-shaped material. A nozzle arrangement is arranged in the conveying direction in front of the front gas nozzle arrangement or behind the rear gas nozzle arrangement, wherein the nozzle arrangement is configured such that a liquid fluid is flowable in a fluid jet into the nozzle floating field in the direction towards the band running plane for temperature-controlling the band-shaped material.
