Annealing hlauNws yog dav siv feem ntau vim nws zoo elasticity thiab yooj, nyob rau hauv tus txheej txheem ntawm annealing yuav ua tau zoo heev tswj ntawm nws hardness, nws yog tsuas yog ua los ntawm hlau hlau, feem ntau siv nyob rau hauv kev tsim kho kev lag luam tied hlau siv.Hauv kev tsim cov hlau annealing yuav ua tiav raws li qhov kev ua tau zoo ntawm cov khoom siv, raws li qhov xav tau ntawm qhov sib txawv ntawm hardness ntawm nws cov kev hloov pauv, tuaj yeem ua rau nws muaj txiaj ntsig zoo dua, tuaj yeem txo cov khoom siv hlau, txo tus nqi ntawm cov khoom. .
Hauv kev siv, tsis tas yuav tsum muaj kev saib xyuas txhua hnub thiab kev saib xyuas, tsis tsuas yog tuaj yeem txuag tau ntau lub sijhawm, tab sis kuj tuaj yeem txo cov nqi, tab sis kuj muaj kev ruaj ntseg zoo, muaj zog corrosion kuj, zoo heev rau kev pab cuam lub neej ntev.Raws li cov txheej txheem sib txawv tau muab faib ua ntau hom, tuaj yeem xaiv raws li lawv tus kheej xav tau.Nrog zoo elasticity thiab elasticity, lub luag hauj lwm tseem ceeb ntawm annealing hlau yog los tswj nws cov degree ntawm softness thiab hardness, nyob rau hauv zus tau tej cov annealing hlausteel hlau, tam sim no siv ntau dua nyob rau hauv kev tsim kho kev lag luam binding siv, piv nrog zoo tib yam hlau kuj yog ntau mos, muaj zoo luster.
Kev siv nyob rau hauv lub neej txhua hnub tsis tas yuav tsum tau ua haujlwm tu thiab tu, txuag sijhawm ntau, tab sis kuj txuag cov nqi kho thiab tu.Cov hlau annealed muaj kev ruaj ntseg zoo thiab corrosion kuj, uas zoo heev prolongs nws cov kev pab cuam lub neej.Muaj ntau hom, uas tuaj yeem xaiv raws li kev siv sib txawv.Cov cuab yeej uacev annealyog qhov yooj yim, uas txhim kho tus nqi siv ntawm lub cuab yeej.Cov khoom siv ntawm cov hlau annealed tuaj yeem ua tau raws li kev ua haujlwm sib txawv.
Tus nqi ntawm galvanized hlau yog siab dua li ntawm cov xaim dav dav, tab sis ntawm qhov kev ua tau zoo, nws kuj zoo dua li cov hlau dav dav.Galvanized hlau yog txheej txheej ntawm zinc nyob rau sab nraud ntawm cov hlau kom zoo dua cov hlau.Thaum ua galvanized hlau, pickling yuav tsum tau nqa tawm.Pickling yog siv qee cov kua qaub los yog kua qaub los ntxuav qee cov oxides ntawm cov hlau, uas yog, xeb, thiab lwm yam corrosive, kom ncav cuag lub hom phiaj ntawm kev ntxuav hlau, kom zinc yuav poob thaum galvanizing.
