Super Duplex 2507 Yeeb Nkab Kub Rolling Txheej Txheem:
1. Raw khoom npaj: Ua ntej, cov khoom siv raw uas xav tau rau duplex stainless hlau 2507 yeeb nkab ntau lawm yuav tsum tau npaj, suav nrog hlau ore, alloy, thiab lwm yam khoom siv.
2. Smelting thiab casting: Cov ntaub ntawv raw li saum toj no yog smelted thiab cam khwb cia los tsim cov khoom siv hauv paus ntawm super duplex 2507 pipeline.
3. Billet kub dov: Tom qab cua sov lub steel billet mus rau ib tug tej yam kub, kub dov yog nqa tawm los ua cov txheej txheem ntawm cov khoom siv rau hauv cov yeeb nkab uas yuav tsum tau.
4. Pickling: Pickling saum npoo ntawm cov yeeb nkab kub dov kom tshem tawm cov oxides saum npoo.
5. Txoj kab uas hla straightening: straighten txoj kab uas hla ntawm lubsuper duplex 2507 yeeb nkablos xyuas kom meej tias cov yeeb nkab txoj kab uas hla zoo ib yam.
6. Annealing kev kho mob: Annealing cov yeeb nkab kom tshem tawm cov kev ntxhov siab thiab qhov tsis xws luag hauv cov txheej txheem kub dov thiab txhim kho cov khoom siv ntawm cov yeeb nkab.
7. Gas-shielded welding: Siv roj-shielded vuam tshuab los vuam cov pob qij txha ntawm cov kav dej kom ntseeg tau qhov zoo thiab kev ntseeg siab ntawm tag nrho cov kav dej.
8. Bright annealing: Bright annealing kho yog nqa tawm ntawm cov kav dej welded kom tau txais qhov zoo ntawm qhov huv.
9. Kev kho deg: Kev kho deg ntawm S32750 super duplex yeeb nkab, txheej txheej los tiv thaiv corrosion, thiab lwm yam.
10. Hydrostatic test: Ua qhov kev ntsuam xyuas hydrostatic kom ntseeg tau tias muaj kev ruaj ntseg ntawm cov kav dej.
11. Kev ntim khoom thiab kev xa khoom: ntim cov kav dej super duplex 2507 raws li cov lus qhia tshwj xeeb, thiab muaj ib tus neeg tshwj xeeb ua kev soj ntsuam zoo, thiab thaum kawg nkoj mus rau cov neeg siv khoom.
