Abstract: 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.

Abstract: The present invention relates to a continuous furnace system for heat treating a metal component, in particular an aluminium strip. The continuous furnace system has a first heating unit, in which the metal component is heatable for solution annealing up to a first temperature in the range of from 350° C. to 700° C., a cooling unit, in which the metal component is coolable from 300° C. to 750° C. down to 70° C. to 250° C., and a second heating unit, in which the metal component is heatable up to from 150° C. to 290° C. The first heating unit, the cooling unit, and the second heating unit both have a common support structure, on which the first heating unit, the cooling unit, and the second heating unit are fixed together.

Abstract: 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.
