Abstract
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.
Claims18
A continuous furnace for the heat treatment of a sheet metal blank, the furnace comprising:
- a first zone and second zone, wherein the first zone has a higher temperature than the second zone,
- a separating wall between the first and second zones, wherein a gap is formed between the sheet metal blank and the separating wall,
- a tubular cooling nozzle arranged at or in the separating wall in a direction towards the second zone, wherein the tubular cooling nozzle has a first group of outlet openings pointing downwards in a vertical direction relative to the separating wall, and
- a surface cooling nozzle arranged in the second zone, wherein the separating wall is horizontally adjustable.
