Claims (22)
1. Förfarande för framställning av ett järnbaserat me-tallband, som är belagt med en beläggningsmetall endast pä ena sidan och vars andra sida är fri frän beläggningsmetallen och som har behandlats för att göra dess ytor rena och fria frän oxid, vid vilket förfarande används en beläggningsdegel, som in-nehäller ett smält bad av beläggningsmetallen, känne- t e c k n a t därav, att det innefattar följande steg: ledan- de av bandet tili ett sädant ställe ovanför badets Övre yta, att ytspänningen och vätningsegenskaperna hos den smälta beläggningsmetallen tilläter bildandet av en menisk vid badets Övre yta, vilken menisk kontaktar den sida av bandet som är vänd mot badet; bildande av menisken, upprätthällande av menisken och med till-hjälp därav kontinuerlig kontaktbeläggning av bandets ena sida; hällande av ätminstone bandets ena sida i oxidfritt tillständ, ätminstone tills menisken har initiellt kontaktat denna sida och slutbearbetning av bandets belagda sida genom avlägsnande av överflödigt beläggningsmaterial frän densamma.
2. Förfarande enligt patentkravet 1,känneteck-n a t därav, att steget, där bandet leds tili nämnda ställe ovanför badets Övre yta, omfattar ledande av bandet kring en enda rulle, som är belägen pä det menisken bildande stället i förhällande tili badytan, och bortledande av det belagda bandet frän badytan efter beläggning av bandets nämnda ena sida.
3. Förfarande enligt patentkravet 1, känneteck-n a t därav, att steget, där bandet leds tili stället ovanför badets Övre yta, omfattar förflyttning av bandet kring en första och en andra rulle, som är belägna parallellt pä ett avständ frän varandra, och bildande av menisken mot bandet i dess av-snitt mellan rullarna.
4. Förfarande enligt nägot av de föregäende patentkraven, kännetecknat därav, att steget, där ätminstone bandets ena sida hälls oxidfri, omfattar hällande av bandet i en skyddande, icke-oxiderande gas, tills menisken har kontaktat nämnda ena sida, varefer det pä den ena sidan belagda bandet avlägsnas frän den skyddande gasen tili den omgivande atmosfären. 27 6120 7
5. Förfarande enligt patentkravet 4, känneteck-n a t därav, att ett steg, där bandets belagda sida slutarbe-tas medelst en sträle med en skyddande, icke-oxiderande gas, innan bandet leds tili den omgivande atmosfären.
6. Förfarande enligt patentkravet 4,känneteck-n a t därav, att det pä den ena sidan belagda bandet avlägsnas tili den omgivande atmosfären medan bandets temperatur är till-räckligt hög, sä att en oxiderad film bildas pä den obelagda sidan.
7. Förfarande enligt patentrkavet 5, känneteck-n a t därav, att bandet hälls i en skyddande, icke-oxiderande gas, tills bandet har kylts tili en sädan temperatur, att ingen oxidfilm bildas pä dess obelagda sida.
8. Förfarande enligt patentkravet 3, känneteck-n a t därav, att nämnda bandavsnitt trycks ned mot det smälta beläggningsmetallbadet.
9. Förfarande enligt nägot av de föregäende patentkraven, kännetecknat därav, att badytan hälls konstant.
10. Anordning för utförande av förfarandet enligt patentkravet 1, vilken anordning omfattar ett medel för att hälla ytor-na hos ett järnmetallband rena och oxidfria och en beläggnings-degel, som innehäller ett smält bad av beläggningsmetall, k ä n -netecknad av ätminstone en rulle (13, 14, 22, 35, 96-98) för ledande av bandet tili ett ställe ovanför badets Övre yta, sä att ytspänningen och vätningsegenskaperna hos den smälta be-läggningsmetallen tilläter bildandet av en menisk vid badets övre yta, vilken menisk kontinuerligt kontaktar och belägger den sidan av bandet som är vänd mot badet, ett i och för sig känt slutbearbetningsmedel (19, 38, 101, 109) för avlägsnande av över-flödig beläggningsmetall frän bandets belagda sida, och ett medel (4-10, 17, 26-32, 37, 87-93, 99) för att hilla ätminstone bandets nämnda ena sida i oxidfritt tillständ ätminstone tills menisken har kontaktat denna sida.
11. Anordning enligt patentkravet 10,känneteck-n a d därav, att ätminstone en rulle (13, 14, 22, 35, 96-98) för ledande av bandet är placerad sä, att bandets under belägg-ning varande yta hälls pä ett avständ av högst 7,95 mm frän nivän av badets övre yta. 28 61 207
