Rolled steel phaj yog dov tawm ntawm lub hauv paus ntawm kub dov kauj, feem ntau hais lus, yog kub dov →passivation ntawm pickling→ txias dov xws li txheej txheem.Txawm hais tias nyob rau hauv tus txheej txheem vim yog dov kuj yuav ua rau cov hlau phaj kub, tab sis tseem hu ua txias dov.
Vim hais tias ntawm cov kub dov tom qab tas mus li txias hloov mus rau hauv txias dov, nyob rau hauv lub mechanical zog kuj tsis zoo, hardness yog siab dhau.Yuav tsum tau faded los kho nws cov khoom siv kho tshuab, tsis muaj fading hu ua dov tawv ntim.Rolled nyuaj ntim feem ntau yog siv los ua tsis muaj dabtsi yog khoov, ncab cov khoom.
Tab sis lub txias dov steel phaj tsim steel phab ntsa thickness yog me me, lub peev xwm los tiv thaiv lub zos concentrated load yog tsis muaj zog, thiab tseem muaj residual stresses nyob rau hauv lub cross-section tom qab shaping, kom lub txias dov steel phaj buckling kev ua tau zoo deterioration, torsion kev ua tau zoo. tsis zoo, corrosion kuj tsis zoo.
Yog li ntawd, txias dov steel phaj feem ntau xaiv siv stainless hlau pickling passivation tov ua pickling passivation txheej txheem,stainless hlau pickling passivationtshuaj tuaj yeem nyob rau hauv passivation tib lub sijhawm kom tshem tawm cov txheej txheej ntawm cov hlau nyias nyias chromium-tsis zoo.Thaum cov tawv nqaij oxide raug tshem tawm, tag nrho cov tshuaj tiv thaiv yog hloov mus rau hauv cov txheej txheem passivation, tsim kev tiv thaiv passivation zoo.Yuav ua tau txhua yam ntawm stainless hlau nto roj, oxide daim tawv nqaij, vuam me ntsis thiab xeb thiab lwm yam phenomena kiag li tshem tawm, thiab tsim ib tug uniform silver-dawb passivation zaj duab xis, zoo heev txhim kho corrosion kuj ntawm lub workpiece.
