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.

Furnace for partially heating metal components

An automotive component is produced by hot forming and press hardening a hardenable steel alloy having a tensile strength of at least 1700 MPa. The hardenable steel alloy, in addition to a balance made up of iron and melting-related impurities, has the following alloy elements carbon, niobium, and titanium. The automotive component is coated by a thermal coating process.
