Abstract
An apparatus for continuously treating metal strip of aluminum, an aluminum alloy, a nonferrous metal, or a nonferrous-metal alloy, has at least one heat-treatment device through which the metal strip passes in a strip-travel plane in a travel direction without contact from an upstream inlet end to a downstream outlet end and having a heating zone at the upstream end and a cooling zone formed by a row extending in the direction of at least two cooling subzones. A strip-centering device between the cooling subzones adjusts a position of the metal strip in the strip-travel plane and transverse thereto.
Claims12
An apparatus for continuously treating metal strip of aluminum, an aluminum alloy, a nonferrous metal, or a nonferrous-metal alloy, the apparatus comprising:
- at least one heat-treatment device through which the metal strip passes in a strip-travel plane in a travel direction without contact from an upstream inlet end to a downstream outlet end and having a heating zone at the upstream end and a cooling zone formed by a row extending in the direction of at least two cooling subzones;
- and
- a strip-centering device between the cooling subzones for adjusting a position of the metal strip in the strip-travel plane and transverse thereto.
A method of continuously treating metal strip of aluminum, an aluminum alloy, a nonferrous metal, or a nonferrous-metal alloy, the method comprising the steps of:
- transporting the strip in a strip-travel plane and in a strip travel direction through a heat-treatment device through which the metal strip passes in a strip-travel plane having an upstream heating zone and a downstream cooling zone formed by a row extending in the direction of at least two cooling subzones such that the strip is heated in the heating zone and cooled in the cooling zone;
- supporting the strip on a fluid cushion in the heat-treatment device;
- and
- adjusting a positon of the strip in the heat-treatment device in the strip-travel plane and transverse thereto between the cooling zones to center the strip in the heat-treatment device.
