The invention relates to a device for processing a metal strip (200) after said metal strip has exited a coating tank (300) having liquid coating material (310). Above the coating tank, the device has a blow-off apparatus (110) having an air outlet slot (112) for blowing liquid parts of the coating off of the metal strip. Arranged above the blow-off apparatus (110) is an electromagnetic stabilization apparatus (140) for stabilizing the metal strip by means of electromagnetic forces after the exiting of the coating tank and the blow-off apparatus. According to the invention, in order to design known devices for treating a metal strip to be more favorable in respect of energy and in order to increase the accessibility of said devices for an operating person, the stabilization apparatus (140) is arranged above the blow-off apparatus (110) in such a way that the distance d between the line of action of the maximum force of the stabilization apparatus on the metal strip and on the air outlet gap (112) of the blow-off apparatus (110) is limited to a range of 100 - 1200 mm.
