Cov roj av feem ntau siv rau lub tshuab tsis txaus ntseeg thiab so cov pa hauv sab hauv, cov pa hluav taws xob khov kho, ntawm cov pa hluav taws xob khov kho, cov pa hluav taws xob. Qhov no vim tias superheated chav tuaj yeem ua kom sov saum toj no cov sortification ntawm zinc nyob rau hauv cov txheej txheem kev ntsuas thiab muaj kev noo noo. Thaum siv los tshuab thiab so cov zinc kua ntawm sab hauv phab ntsa ntawm galvanized steel kav dej, nws tsis txias me ntsis nce nws qhov kub. Qhov no tau txais txiaj ntsig zoo rau kev smoothing cov zinc ua rau ntawm phab ntsa puab. Ib qho ntxiv, cov khoom siv hluav taws xob superheated yog qhov yooj yim thiab tuaj yeem muab tau yooj yim siv hauv feem ntau cov chaw ua haujlwm. Hauv kev sib piv, cov chav khov muaj dej noo ntau thiab muaj qhov kub tsawg dua, uas tuaj yeem nqus tau cua sov los ntawm cov zinc kua thiab ua kom nrawm nws cov sololification. Compressed huab cua, txawm hais tias muaj tsawg dua noo noo, tuaj yeem ua kom nrawm nrawm ntawm zinc kua, nce qhov tsis kam thaum dhau mus los ntawm sab hauv gorvanized steel kav thiab cuam tshuam lub tshuab thiab cov txheej txheem wiping. Kev siv cov pa kub nias rau sab hauv tshuab thiab so ntawm zinc yog qhov tsis tshua muaj siab nyob rau hauv kev ua tiav qhov kev ua tiav ntawm kev ua tiav qhov kev ua tau zoo, thiab muaj cov khoom siv hnyav dua thiab siv hluav taws xob.
Yog tias huab cua compressed yog thawj zaug siv rau lub tshuab sab nraud thiab so, nws yuav tsum tau siv cov cua sov (lossis cov cua kub siab dua) ntawm cov cua tshuab thiab tab tom rub tawm ntawm zinc.
