초록

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.

대표청구항 ▼

1. A method for meniscus coating in an ambient atmosphere at least one surface of a metal strip having a sidewall edge, the method comprising the steps of: (a) providing: (i) at least one horizontally disposed coating tray, wherein the at least one coating tray comprises a top lip and a lip adjacent sidewall,(ii) a roll enclosure containing a protective atmosphere, wherein the roll enclosure is disposed adjacent the at least one coating tray, wherein the roll enclosure comprises a cover such that a space is defined between the top lip and the cover, wherein the cover comprises an aperture, and the aperture comprises a strip receiving portion and at least one open portion, and(iii) at least one baffle, wherein the at least one baffle: a. substantially covers the at least one open portion of the aperture; andb. is adjusted to develop in the space a positive pressure relative to the ambient atmosphere;(b) advancing the metal strip through the aperture of the cover of the roll enclosure;(c) advancing the metal strip toward the top lip of the at least one coating tray;(d) maintaining a coating metal on the top lip of the at least one coating tray; and(e) 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. 2. The method of claim 1, further comprising receiving and shaping the metal strip via at least one roll, wherein the at least one roll is disposed within the roll enclosure. 3. The method of claim 1, further comprising: (a) providing at least one gas delivering device;(b) delivering a gas via the at least one gas delivering device, wherein the at least one gas delivering device is disposed proximate to the cover of the roll enclosure. 4. The method of claim 1, wherein the at least one baffle further comprises: (a) a flat portion disposed over the at least one open portion of the aperture, wherein the flat portion has an interior edge that faces the strip receiving portion; and(b) a sidewall portion that upwardly extends from the interior edge to abut against the sidewall edge of the metal strip as it is received through the strip receiving portion of the aperture. 5. The method of claim 4, wherein the sidewall portion is sealed against the lip adjacent sidewall of the coating tray. 6. The method of claim 1, wherein the coating tray comprises an undersurface, the method further comprising the step of forming a seal between the undersurface of the coating tray and the cover of the roll enclosure. 7. A method for meniscus coating in an oxidizing atmosphere two opposed surfaces of a metal strip, wherein the metal strip comprises a first sidewall edge and a second sidewall edge and at least one surface of the metal strip is oxidizable, the method comprising: (a) providing in the oxidizing atmosphere: (i) a first horizontally disposed coating tray comprising a first top lip and a first lip adjacent sidewall; and(ii) a second horizontally disposed coating tray comprising a second top lip and a second lip adjacent sidewall;(ii) a roll enclosure having a non-oxidizing atmosphere, wherein the roll enclosure: 1. comprises a cover having an aperture, the aperture comprising: a. a strip receiving portion;b. a first open portion; andc. a second open portion; and2. is disposed beneath the first and second horizontally disposed coating trays such that a space is defined between the first top lip, first lip adjacent sidewall, second top lip, second lip adjacent sidewall and the cover of the roll enclosure;(iii) a first baffle comprising: 1. a flat portion disposed over the first open portion of the aperture, wherein the flat portion has an interior edge that faces the strip receiving portion of the aperture; and2. a sidewall portion that upwardly extends from the interior edge to abut against the first sidewall edge of the metal strip as it is received through the strip receiving portion of the aperture,wherein the sidewall portion is sealed against the first lip adjacent sidewall of the first coating tray, (iv) a second baffle comprising: 1. a flat portion disposed over the second open portion of the aperture, wherein the flat portion has an interior edge that faces the strip receiving portion of the aperture; and2. a sidewall portion that upwardly extends from the interior edge to abut against the second sidewall edge of the metal strip as it is received through the strip receiving portion of the aperture, wherein the sidewall portion is sealed against the second lip adjacent sidewall of the second coating tray;wherein the first and second baffles are adjusted to maintain the non-oxidizing atmosphere of the roll enclosure in the space;(b) advancing the metal strip through the aperture of the cover of the roll enclosure;(c) advancing the metal strip toward the first top lip and the second top lip;(d) maintaining a coating metal on the first top lip and the second top lip; and(e) coating the two opposed surfaces of the metal strip with the coating metal when the metal strip advances past the first top lip and the second top lip into the oxidizing atmosphere. 8. The method of claim 7, further comprising receiving and shaping the metal strip via at least one roll, wherein the at least one roll is disposed within the roll enclosure. 9. The method of claim 7, further comprising: (a) providing at least one gas delivering device;(b) delivering a gas via the at least one gas delivering device, wherein the at least one gas delivering device is disposed proximate to the cover of the roll enclosure. 10. The method of claim 7, wherein the coating tray comprises an undersurface, the method further comprising the step of forming a seal between the undersurface of the coating tray and the top cover of the roll enclosure.
