Abstract
A meniscus coating apparatus and method for coating at least one surface of a metal strip includes an apparatus having an adjustable coating tray, a roll enclosure disposed adjacent the coating tray, an adjustable baffle, and/or a gas delivery device operable to help seal the roll enclosure.
Claims16
An apparatus for meniscus coating at least one surface of a metal strip, comprising:
- (a) at least one horizontally disposed coating tray, wherein the at least one coating tray comprises a top lip and wherein the top lip is configured to coat the at least one surface of the strip;
- (b) a roll enclosure disposed adjacent the at least one coating tray, wherein the roll enclosure comprises a cover, wherein the cover comprises an aperture, and wherein the aperture comprises a strip receiving portion and at least one open portion;
- and
- (c) at least one baffle, wherein the at least one baffle is configured to cover the at least one open portion of the aperture.
1 more element
An apparatus for meniscus coating opposing surfaces of a metal strip, comprising:
- (a) at least one horizontally disposed coating tray, wherein the at least one coating tray comprises a top lip, and wherein the top lip is configured to coat the at least one surface of the strip;
- (b) a roll enclosure disposed adjacent the at least one coating tray, wherein the roll enclosure comprises a cover, wherein the cover comprises an aperture;
- and
- (c) at least one gas delivering device, wherein the at least one gas delivering device is operable to deliver gas to minimize ingress of ambient gases into the roll enclosure and is disposed proximate to the cover of the roll enclosure.
1 more element
An method for meniscus coating at least one surface of a metal strip, comprising:
- (a) providing:
- (i) at least one horizontally disposed coating tray, wherein the at least one coating tray comprises a top lip,
- (ii) a roll enclosure disposed adjacent the at least one coating tray, wherein the roll enclosure comprises a cover, wherein the cover comprises an aperture, and
- (iii) at least one baffle;
- (b) covering at least a portion of the aperture with the at least one baffle;
- (c) advancing the metal strip through the aperture of the cover of the roll enclosure;
- (d) advancing the metal strip toward the top lip of the at least one coating tray;
- (e) maintaining a coating metal on the top lip of the at least one coating tray;
- and
- (f) coating the at least one surface of the metal strip with the coating metal when the metal strip advances past the top lip of the at least one coating tray.
