Rolledtooj liab ntawv ci, ib tug kheej kheej qauv hlau ntawv, yog tsim thiab tsim los ntawm lub cev dov txoj kev, nws cov txheej txheem tsim raws li nram no:
Ingoting:Cov khoom siv raw yog thauj mus rau hauv lub qhov cub tawg kom muab pov rau hauv ib qho square kem-shaped ingot.Cov txheej txheem no txiav txim siab cov khoom ntawm cov khoom kawg.Nyob rau hauv cov ntaub ntawv ntawm cov khoom siv tooj liab, lwm yam hlau ntxiv rau tooj liab yuav raug fused hauv cov txheej txheem no.
↓
Rough(Kub)Rolling:Lub ingot yog rhuab thiab dov mus rau hauv ib co coiled intermediate khoom.
↓
Acid Pickling:Cov khoom nruab nrab tom qab ntxhib dov yog ntxuav nrog cov kua qaub tsis muaj zog kom tshem tawm cov oxide txheej thiab impurities ntawm cov khoom siv.
↓
Precision(Txias)Rolling:Cov khoom siv huv huv nruab nrab yog dov ntxiv kom txog thaum nws tau dov mus rau qhov kawg xav tau tuab.Raws li cov khoom siv tooj liab hauv cov txheej txheem dov, nws tus kheej cov khoom hardness yuav dhau los ua nyuaj, cov khoom siv nyuaj heev yog qhov nyuaj rau dov, yog li thaum cov khoom ncav cuag ib qho nyuaj, nws yuav yog nruab nrab annealing kom txo cov khoom hardness, thiaj li yuav pab tau dov. .Nyob rau tib lub sijhawm, txhawm rau zam cov yob hauv cov txheej txheem dov ntawm cov khoom siv los ntawm kev sib sib zog nqus embossing, high-end mills yuav muab tso rau ntawm cov khoom thiab cov yob hauv cov yeeb yaj kiab roj, lub hom phiaj yog ua qhov kawg khoom nto tiav siab dua.
↓
Degreasing:Cov kauj ruam no tsuas yog muaj nyob rau hauv cov khoom siv high-end, lub hom phiaj yog los ntxuav cov roj txhua yam coj los rau hauv cov khoom thaum lub sij hawm dov.Nyob rau hauv cov txheej txheem ntxuav, oxidation kuj kho nyob rau hauv chav tsev kub (tseem hu ua passivation kev kho mob) feem ntau yog nqa tawm, piv txwv li passivation tus neeg saib xyuas yog muab tso rau hauv cov tshuaj ntxuav kom qeeb oxidation thiab discoloration ntawm tooj liab ntawv ci nyob rau hauv chav tsev kub.
↓
Annealing:Sab hauv crystallization ntawm cov khoom siv tooj liab los ntawm cua sov ntawm qhov kub thiab txias, yog li txo nws cov hardness.
↓
Roughening(yeem): Qhov saum npoo ntawm cov ntawv ci tooj liab yog roughened (feem ntau tooj liab hmoov los yog cobalt-nickel hmoov yog sprayed rau saum npoo ntawm tooj liab ntawv ci thiab ces kho) kom roughness ntawm tooj liab ntawv ci (kom nws tev lub zog).Nyob rau hauv cov txheej txheem no, lub ci ntsa iab saum npoo kuj raug kho nrog kub-kub oxidation kev kho mob (electroplated nrog ib txheej ntawm hlau) kom cov khoom muaj peev xwm ua hauj lwm nyob rau hauv high kub yam tsis muaj oxidation thiab discoloration.
(Faj seeb: Cov txheej txheem no feem ntau ua tau tsuas yog thaum xav tau cov khoom siv)
↓
Slitting:dov tooj liab ntawv ci khoom yog muab faib ua qhov dav raws li tus neeg yuav tsum tau ua.
↓
Kev kuaj:Txiav ob peb cov qauv los ntawm cov yob tiav rau kev ntsuam xyuas cov khoom muaj pes tsawg leeg, tensile lub zog, elongation, kam rau ua, tev lub zog, roughness, tag thiab cov neeg yuav tsum tau ua kom paub tseeb tias cov khoom tsim nyog.
↓
Ntim:Ntim cov khoom tiav uas ua tau raws li cov kev cai hauv batch rau hauv lub thawv.
