Hlau yog cov khoom siv nrog qee yam zoo li, qhov loj me thiab kev ua haujlwm ua los ntawm cov hlau ingots, billets lossis steel los ntawm kev ua haujlwm siab. Feem ntau ntawm cov txheej txheem steel yog ua los ntawm kev ua haujlwm siab, yog li cov hlau ua tiav ua cov yas deformation. Nyob rau niaj hnub no cov huab cua tsis zoo zuj zus tuaj, steel raug rau sab nraum zoov lub sijhawm ntev yuav ua rau corrosion. Hauv no blog ncej, peb yuav qhia ntau txoj hauv kev ntawm kev tiv thaiv steel hlau.
Feem ntau, thaum ua cov hlau, cov tuam txhab lag luam yuav xav txog kev ntxiv cov tshuaj tiv thaiv corrosion rau cov hlau. Yog tias cov txheej txheem ntom ntom, nws tuaj yeem tiv thaiv kev nkag mus ntawm cov roj corrosive thiab kua, thiab tuaj yeem tiv thaiv kev tsim hluav taws xob zoo li qub hauv txheej txheej. Nws cov conductivity siab tuaj yeem tiv thaiv lub cev thiab tshuaj lom neeg ntawm corrosive acid- hauv paus xov xwm. Tsis tas li ntawd, txheej txheej muaj siab hardness, cuam tshuam tsis kam, softness thiab plumpness. Nws qhov ntsuas kub tsis kam yog -45℃-150 degree. Nws muaj lub siab thermal shock coefficient thiab zoo adhesion. Yog li ntawd, nws yog tsim nyog rau txheej nyob rau hauv ntau yam acid-base gases thiab kua, kuab tshuaj, intermediates thiab ib nrab concentrations ntawm ntsev los tiv thaiv corrosion thiab tiv thaiv kab mob los ntawm corrosion mus ntev.
Cov txheej hauv qab ntawm txheej yog txheej txheej galvanized, thiab txheej txheej saum npoo yog txheej txheej stainless hlau, tsim cov txheej txheej txheej, uas yog siv rau hydraulic steel qauv. Tom qab ntau kev tshawb fawb thiab kev sim, kev lag luam thiab kev txaus siab los tiv thaiv corrosion ntawm steel qauv tau ua tiav. Lub hauv paus ntsiab lus yog siv qee hom hluav taws xob los ua kom sov cov hlau sputtering khoom los tsim cov khoom molten. Nyob rau hauv qhov kev txiav txim ntawm lub hwj chim, nws yuav cuam tshuam thiab nkag mus rau hauv qhov chaw ntawm lub substrate ntawm ib qho kev ceev los tsim cov hlau txheej nrog qee yam ntxwv. Cov txheej txheej muaj zog tiv thaiv corrosion thiab acid- puag kuj, yog li nws tuaj yeem ua tau raws li qhov yuav tsum tau ua los tiv thaiv corrosion ntawm ntau zaus. Cov qauv hlau, phab ntsa nto thiab cov khoom siv ua haujlwm ntawm cov kua qaub- lub hauv paus rhiav tuaj yeem coated nrog cov xim, ntxiv rau kev tiv thaiv corrosion rau hauv pem teb ntawm lub rooj cob qhia tseem ceeb kom ua tiav cov txiaj ntsig zoo los tiv thaiv corrosion.
Lwm txoj kev zoo los tiv thaiv corrosion yog thermal hlau txau. Nws siv ib daim ntawv ntawm cov cua sov los ua kom sov cov khoom siv hlau los ua cov khoom molten. Nyob rau hauv qhov kev cuam tshuam siab, nws cuam tshuam thiab tso rau saum npoo ntawm lub substrate ntawm ib qho kev ceev kom tsim cov hlau txheej nrog qee yam ntxwv. Nws siv cov thev naus laus zis thev naus laus zis los kho qhov chaw ntawm cov ntaub ntawv hauv paus xws li hydraulic steel cov khoom siv kom tau txais kev tiv thaiv corrosion thiab hnav-resistant hlau tiv thaiv txheej, yog li txhim kho corrosion kuj thiab hnav tsis kam ntawm hydraulic steel yam ntxwv qhov chaw.
