Dab tsi cuam tshuam rau qhov hardness ntawm stainless hlau AP kav?

Puas yog nws zoo dua kom muaj qhov muag muag lossis nyuaj dua stainless hlau AP yeeb nkab?

Niaj hnub no, cov kav hlau tsis muaj steel hlau ua los ntawm 304 thiab 201 cov ntaub ntawv yog siv, thiab muaj ob yam uas cuam tshuam rau qhov nyuaj ntawm AP stainless hlau kav: strip annealing thiab cov ntsiab lus carbon ntawm stainless hlau kav.
Ib qho tseem ceeb yog qhov teeb meem ntawm cov sawb hlau ntawm cov yeeb nkab steel hlau thaum quenching. Qhov zoo ntawm strip annealing tuaj yeem cuam tshuam ncaj qha rau lub hardness ntawm stainless hlau yeeb nkab. Txawm hais tias nws yog 201 lossis 304 stainless hlau yeeb nkab, kuv lub teb chaws muaj cov qauv sib xws rau nws qhov nyuaj.
Lwm qhov tseem ceeb yog cov ntsiab lus carbon hauv cov yeeb nkab steel hlau. Lub luag haujlwm tseem ceeb ntawm cov pa roj carbon monoxide hauv cov yeeb nkab steel hlau yog txhawm rau ua kom lub zog ntawm cov yeeb nkab, tab sis cov pa roj carbon monoxide kuj yog ib qho seem hauv cov phaj hlau stainless. Nyob rau tib lub sijhawm, cov ntsiab lus nyuaj, qhov ntau dua qhov muaj peev xwm ntawm corrosion ntawm cov yeeb nkab.
Qhov saum npoo ntawm cov yeeb nkab stainless hlau tsis ci thaum nws tsuas yog tsim. Hloov chaw, ib txheej ntawm grey-dub lossis grey-dawb oxide nplai yuav tshwm sim, uas yog qhov nyuaj heev rau yaj. Txawm li cas los xij, txheej txheej ntawm oxide nplai no yuav tsis tsuas yog cuam tshuam rau qhov pom ntawm qhov chaw, tab sis kuj cuam tshuam rau kev ua haujlwm ntawm cov yeeb nkab,
yog li cov yeeb nkab yuav tsum tau polished. Muaj peb yam tseem ceeb uas cuam tshuam rau qhov zoo ntawm stainless hlau AP yeeb nkab polishing:
1. Qhov tsis xws luag ntawm cov yeeb nkab: xws li cov xuab zeb qhov, khawb, cov pob dub, thiab lwm yam;
2. Cov khoom siv teeb meem ntawm cov yeeb nkab: Piv txwv li, yog tias qhov hardness ntawm cov yeeb nkab yog tsawg, nws tsis yooj yim rau polish yog tias nws yog mos heev, thiab nws yooj yim los tsim cov txiv kab ntxwv tev;
3. Cov cuab yeej sib tsoo thiab cov cuab yeej siv tshuab: Txawm li cas los xij cov yeeb nkab steel hlau nws tus kheej zoo npaum li cas, yog tias cov cuab yeej sib tsoo thiab cov cuab yeej siv tsis tau raws li tus qauv, cov yeeb nkab zoo yuav raug puas tsuaj.
