Lub tuam txhab xaim hais tiastxoj kabyuav kub hnyiab hauv cov pa oxygen, muab cov cua kub ntau, cov nplaim taws thiab cov khoom dub, thiab thaum cov hlau yog xeb, cov pa oxygen tsis huv, cov hlau yog tuab heev, cov combustion tshwm sim yuav tsis pom tseeb lossis pom.Thiab lub txim feem ntau tshwm sim los ntawm cov hlau hlawv hauv cov pa oxygen, feem ntau vim nws muaj qee qhov impurities hauv cov tshuaj tiv thaiv.
Cov hlau tuaj yeem xav tias yog hlau encased nyob rau hauv cov pa roj carbon monoxide, thiab thaum tua, cov pa roj carbon monoxide qis tuaj yeem nkag mus rau hauv cov pa oxygen, tsim cov pa roj carbon dioxide uas ua rau cov hlau nyob hauv nws.Sodium thiab magnesium muaj tsawg combustible impurities, tua tsuas yog lub teeb.Qhov ntau carbon nyob rau hauvtxoj kab, qhov ntau yuav ua rau muaj txim.Cov hlau coated carbon ua zoo li tawg nyob rau hauv ib lub hnab ntim, qee zaus blasting cov hlau tawm.
Kub plating hlau yog ua los ntawm cov roj carbon zoo tsis zoo, tom qab kos duab molding, pickling xeb tshem tawm, kub kub annealing, kub dip galvanizing, txias thiab lwm yam txheej txheem.Cov txheej txheej rwb thaiv tsev ntawm cov khoom siv rwb thaiv tsev nyuaj tuaj yeem ua ob txoj hlua khigalvanized hlau hlaunrog tsis muaj.16 ~ Nr.18, thiab qhov sib nrug ntawm kev khi yuav tsum tsis txhob siab tshaj 400mm.Txawm li cas los xij, cov kav dej lossis cov khoom siv sib txuas nrog nominal txoj kab uas hla sib npaug los yog ntau dua 600mm yuav tsum tau ntxiv nrog cov hlau galvanized ntawm No. 10 txog No. 14 los yog ntim steel siv tom qab bunching, thiab qhov sib nrug ntawm kev txhawb nqa yuav tsum yog 500mm.
Lub rwb thaiv tsev txheej ntawm semi-hard thiab mos rwb thaiv tsev cov khoom yuav tsum tau khi nrog packing steel daim kab xev, galvanized hlau hlau tsis muaj.14 to nr.16 los yog nplaum daim kab xev nrog qhov dav ntawm 60mm raws li cov yeeb nkab txoj kab uas hla thiab cov khoom loj.Qhov sib nrug ntawm txoj hlua khi, cov khoom siv rwb thaiv tsev ib nrab yuav tsum tsis txhob siab tshaj 300mm;Rau qhov muag muag, ncoo yuav tsum tsis txhob siab tshaj 200mm.
