A device for coating a metal strip with a liquid coating material comprises a coating container filled with, for example, liquid zinc. After the metal strip exits the coating container, liquid coating material adheres to the metal strip. Excess coating material is blown away from the surface of the metal strip by a blowing device. Thereafter, the metal strip runs through an electromagnetic stabilization device which is supported on the blowing device. Disturbing influences may cause the metal strip to no longer run centrally through a slot of the blowing device. A displacement or re-alignment of the blowing device is then required to guide the metal strip back to the set middle position. A first displacing device displaces the electromagnetic stabilization device relative to the blowing device in the plane transverse to the direction of transport of the metal strip to avoid an undesirable displacement of the electromagnetic stabilization device.

Device for coating a metal strip with separately movable electromagnetic stabilizing device and blowing device

A method and a device for coating a metal strip with a coating material which is at first still liquid. A first displacing device for displacing an electromagnetic stabilisation device relative to a blowing device in the plane transverse to the direction of transport of the metal strip is provided.

Device including electromagnetic stabilizing device and blowing device

An apparatus for treating a metal strip after it has exited from a coating container with a liquid coating material, for example zinc is provided. The apparatus includes a blow-off device arranged above the coating container having an air outlet gap for blowing off excess parts of the still liquid coating material from the surface of the metal strip after the passing of the metal strip through the coating container. An electromagnetic stabilizer is arranged above the blow-off device and has a plurality of individual magnets for stabilizing the metal strip after leaving the coating container and the blow-off device. In order to further increase the efficiency of the apparatus, at least some of the magnets of the stabilizer are formed as pot magnets with pot coils.

Apparatus for treating a metal strip including an electromagnetic stabilizer utilizing pot magnets

A method for operating a coating device for coating a metal strip. The corresponding coating device has an electromagnetic strip-stabilizing device having a plurality of electromagnetic actuators or coils for applying forces to the metal strip. In order to ensure that the strip-stabilizing device is operated only within the operating limits thereof, the magnitudes of the set currents for the actuators or the coils are compared with a specified current threshold value or the forces applied to the metal strip by the actuators are compared with a specified force threshold value and the correction roller is moved into such an adjustment position that the magnitudes of the set currents are below the current threshold value or the magnitudes of the forces are below the force threshold value.

Method and device for coating a metal strip with a coating material which is at first still liquid

A device for processing a metal strip with a liquid coating material is disclosed. Above a coating tank filled with coating material, the device has a blower having an air outlet slot for blowing liquid parts of the coating off of the metal strip. Arranged above the blower is an electromagnetic stabilizer for stabilizing the metal strip by electromagnetic forces after the exiting of the coating tank and the blower. 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 for an operating person, the stabilizer is arranged above the blower in such a way that the distance d between the line of action of the maximum force of the stabilizer on the metal strip and on the air outlet gap of the blower is limited to a range of 100-1200 mm.

Device for treating a metal strip with a liquid coating material

A method and a device for coating a metal strip with a coating material that is still liquid at first. During the coating, the coated metal strip runs through a roller pair. One of the rollers of the roller pair can be adjusted toward the other as a correction roller in order to eliminate a possible curvature of the metal strip. Then the metal strip runs through a blow-off apparatus for blowing off surplus coating. In order to prevent an uneven thickness distribution of the coating on the metal strip even when the correction roller of the roller pair has been adjusted, the actual position of the metal strip is controlled to a specified setpoint center position in the slot of the blow-off apparatus by an appropriate movement of the blow-off apparatus.
