Device for the heat treatment of coated semifinished steel products

An apparatus for heat treatment of coated semi-finished steel products, the apparatus comprising:

• at least one heatable continuous furnace comprising
• at least one conveyer for moving the coated semi-finished steel products, wherein the at least one conveyer has conveyer elements for supporting the coated semi-finished steel products;
• and
• at least one decoupling portion comprising a first conveyer element group and a second conveyer element group, with each of the first and second conveyer element groups having at least one conveyer element for supporting the coated semi-finished steel products, wherein in the at least one decoupling portion the at least one conveyer element of the first conveyer element group is configured to support a first subset of the coated semi-finished steel products, wherein the coated semi-finished steel products in the first subset have an Al—Si coat, wherein in the at least one decoupling portion the at least one conveyer element of the second conveyer element group is configured to support a second subset of the coated semi-finished steel products, wherein the coated semi-finished steel products in the second subset have a coat that is different than the Al—Si coat on the coated semi-finished steel products in the first subset.

A heatable continuous furnace for heat treatment of coated semi-finished steel products, the heatable continuous furnace comprising:

• at least one conveyer device for moving the coated semi-finished steel products, wherein the at least one conveyer device has conveyer elements for supporting the coated semi-finished steel products in the heatable continuous furnace;
• and
• at least one decoupling portion having at least a first conveyer element group and a second conveyer element group, with each of the first and second conveyer element groups having at least one conveyer element, wherein the coated semi-finished steel products are supported in the at least one decoupling portion either by the at least one conveyer element of the first conveyer element group or by the at least one conveyer element of the second conveyer element group,
• wherein the coated semi-finished steel products that are Al—Si-coated are supported by the at least one conveyer element of the first conveyer element group, wherein the coated semi-finished steel products that are coated with a further coating system on an organic or inorganic basis are supported by the at least one conveyer element of the second conveyer element group.

A heatable continuous furnace for heat treatment of coated semi-finished steel products, the heatable continuous furnace comprising:

• a conveyer for moving the coated semi-finished steel products through the heatable continuous furnace, the conveyer having a plurality of conveying elements for supporting the coated semi-finished steel products;
• and
• a decoupling portion having a first conveyer element group and a second conveyer element group, with each of the first and second conveyer element groups having at least one of the plurality of conveying elements for supporting the coated semi-finished steel products,
• wherein the conveyer delivers the coated semi-finished steel products to either the first conveyer element group or the second conveyer element group depending on a coating of each of the coated semi-finished steel products.
