Alloyed galvanized steel kauj. Cov hlau kauj no kuj yog ua los ntawm kub dip, tab sis tam sim ntawd tom qab lub trough, nws yog rhuab mus txog 500 degree, thiaj li hais tias nws generates ib tug alloy zaj duab xis ntawm zinc thiab hlau. Qhov no galvanized coil muaj cov txheej txheem zoo adhesion thiab weldability.
Nws yog tsim los ntawm cov txheej txheem txuas ntxiv galvanizing, uas yog, coiled steel phaj yog txuas ntxiv rau hauv zinc-melted plating tank los ua galvanized steel phaj; alloyed galvanized steel phaj. Cov phaj hlau no kuj yog ua los ntawm cov txheej txheem kub-dip, tab sis nws yog rhuab mus txog 500 degree tam sim ntawd tom qab tawm hauv lub tank los tsim cov yeeb yaj kiab ntawm zinc thiab hlau. Qhov nogalvanized steel kaujmuaj cov xim zoo adhesion thiab weldability.
Kub dip txheej txheem txias dov coil yog carbon steel coated nrog zinc. Txoj kev galvanizing feem ntau yog cov txheej txheem kub-dip.
Txawm hais tias qhov no yog daim ntawv ntau tshaj plaws ntawm galvanizing, vim hais tias cov thickness ntawm cov khoom kawg tsis yooj yim los tswj, nws yog feem ntau yog siv rau yav tas los tsim steel. Lwm txoj kev ntawm galvanizing txheej txheem yog nruam galvanizing.
Tom qab nruam galvanizing dhau los ntawm zinc da dej, galvanizing yuav tsum tau ua nyob rau saum npoo ntawm nruam steel sawb (coil). Cov txheej txheem kub dipping yog hla cov hlau los ntawm kev da dej ntawm zinc molten, thaum cov txheej txheem electro-galvanizing muaj kev thov zinc los ntawm electrolytic disposition.
