Galvanized coil, simbi yakatetepa shizha inonyikwa mubhavhu rezinc yakanyungudutswa kuti inamire dangwe rezinc kumusoro kwayo.Iyo inonyanya kugadzirwa nekuenderera mberi kwekuita galvanizing process, kureva kuti, simbi yakamonerwa ndiro inoramba ichinyikwa mudhiri replating ine zinc yakanyungudutswa kugadzira ndiro yesimbi yakakoswa;alloyed galvanized steel plate.Rudzi urwu rwepaneru yesimbi inogadzirwawo neinopisa dip nzira, asi inopisa kusvika 500 ℃ pakarepo mushure mekubuda mutangi, kuitira kuti igadzire alloy firimu rezinc nesimbi.Izvigalvanized coilane pendi yakanaka adhesion uye weldability.
(1) Normal spangle coating spangle coating
Munguva yemazuva ese ekusimba kweiyo zinc layer, zviyo zvezinc zvinokura zvakasununguka uye zvinogadzira jira rine pachena spangle morphology.
(2) Yakaderedzwa spangle coating
Munguva yekusimba kweiyo zinc layer, zinc zviyo zvinodzivirirwa zvekugadzira kugadzira spangle coating diki sezvinobvira.
(3) Hapana spangle coating spangle-isina
Nekugadzirisa makemikari ekugadzirisa kwekugadzirisa, hapana chinooneka spangle morphology uye yunifomu yekuputira pamusoro.
(4) zinc-iron alloy coating zinc-iron alloy coating
Kupisa kupisa kunoitwa pamutsetse wesimbi mushure mekupfuura nemubhati rekugezesa, kuitira kuti iyo yose yekuputira iite alloy layer ye zinc nesimbi.Chitarisiko chejasi iyi yakasviba grey, isina simbi inopenya, uye zviri nyore kupuruzira panguva yechisimba chekugadzira maitiro.Kunze kwekuchenesa, machira anogona kuvezwa zvakananga pasina kumwe kurapwa.
(5) kusiyana kwekupfeka
Pamativi ese ari maviri epepa resimbi, machira ane akasiyana zinc layer huremu anodiwa.
(6) Smooth skin pass
Skin pass inzira inotonhora yekukunguruka ine diki deformation pamarata emaratanokuda kwechimwe kana kupfuura chezvinangwa zvinotevera.
Kuvandudza kutaridzika kwepamusoro pemarata esimbi kana kuve akakodzera machira ekushongedza;kuderedza kwenguva pfupi chiitiko chemitsetse inotsvedza (Lüders mitsara) kana zvimedu zvinogadzirwa panguva yekugadzirisa zvigadzirwa zvakapedzwa, nezvimwe.
