The present invention relates to an oven device for heat-treating a blank. The oven device has an oven housing having an oven chamber, in which the blank can be heat-treated with a defined temperature, and a tempering body, which is arranged in the oven chamber. Furthermore, the oven device has a tempering body and a tempering device. The tempering device is arranged within the oven chamber movably between a first position and a second position, such that the tempering device is, at least in the first position, in thermal contact with the tempering body and can, in the second position, be brought in thermal contact with the blank.

Oven device for heat-treating a metal blank

An apparatus is described for cooling a metal strip (), comprising at least two nozzle fields which are disposed opposite of each other with respect to the metal strip () conveyed continuously in its longitudinal direction and which comprise nozzles facing towards the respective strip surface and being attached to blowing boxes () for a cooling gas, and flow conduits () provided between the nozzles for discharging the cooling gas flows from the nozzles which are deflected on the surface of the strip. In order to provide advantageous cooling conditions it is proposed that the nozzles are combined in groups in nozzle strips () which are disposed next to one another in parallel with lateral distance and which consist of gas conduits () connected with the blowing boxes () and comprising nozzle openings () facing the respective strip surface and being distributed over the length of the nozzle strips (), and that the flow conduits () for discharging the cooling gas flows are provided between the nozzle strips () extending transversally to the blowing boxes ().
