Method and device for heat treatment of metal workpieces.

Procedure for heat treatment of workpieces (20) metal, or stacks of these formed by several metal workpieces are superposed on each other in vertical direction, with a longitudinal extension which exceeds the cross section of the workpieces ( 20) or stacks of workpieces, in which after pre-heating of workpieces (20) or stacks of workpieces are cooled them with a quenching gas in a chamber (10 ) quenching, wherein the workpieces (20) or stacks of workpieces are subjected in a controlled manner the movement of a quenching gas in a direction parallel to the direction of the longitudinal extension of the pieces circulation work (20), or stacks of workpieces, by means of guide channels (30) are configured so relevant, they have a closed outer surface and cover by c ompleto the workpieces (20) or batteries of workpieces along the flow direction of the quenching gas, being conducted this quenching gas into a closed circulating circuit by means of a channel circulation (14) connected to the quenching chamber (10) according to the technique of fluid flow.
