A method and a device serve for treating primary gas from a metallurgical vessel for the effective reduction of NOx constituents. The primary gas is supplied with a reducing agent. Additionally, secondary gas is suctioned at an auxiliary suction point in the surroundings of the metallurgical vessel. The primary gas is mixed with the colder secondary gas to produce a gas mixture. Thereby NOx constituents in the primary gas are effectively reduced without an undesired reactive influence on the process within the metallurgical furnace and without requiring high investment costs. This is achieved in that the primary gas is mixed with the secondary gas prior to supplying the reducing agent, namely such that the gas mixture is cooled to a temperature ranging from 400° C. to 600° C. prior to supplying the reducing agent, and the reducing agent is then supplied to the gas mixture, containing the primary gas.

Method and computer program product for calculating a pass schedule for a stable rolling process
A method and a corresponding computer program product calculate a pass schedule for a stable rolling process when rolling metal strip in a rolling mill.
