HOLLOW ntu SHIPBUILDING

Nyob rau hauv cov txheej txheem kub-dip galvanizing tas mus li, coils ntawm dov hlau tsis tu ncua thiab pub los ntawm kev ntxuav thiab annealing seem ua ntej nkag mus rau molten zinc da dej ntawm speeds txog 200 meters ib feeb. Raws li cov hlau tawm ntawm cov zinc molten da dej, roj 'riam' so tawm cov txheej txheej ntau dhau los ntawm cov ntawv hlau los tswj cov txheej tuab. Lub steel sawb ces undergoes ib tug series ntawm mechanical los yog tshuaj kho mob. Raws li cov neeg siv khoom xav tau, cov ntawv coated steel tuaj yeem passivated, oiled thiab recoiled, thiab txiav kom ntev thiab palletized ua ntej xa mus rau tus fabricator. Tag nrho cov txheej galvanized yog metallurgically sib raug zoo rau cov hlau lawv tiv thaiv. Qhov no ua kom cov txheej adhesion - qhov tseem ceeb rau kev tsim cov txheej txheem uas stamp, yob lossis kos cov hlau rau hauv nws cov khoom kawg.
