Automotive steel manufacturing zaub:
Automotive steel manufacturing txheej txheem:
Muaj ntau hom txias-kuav los tiag steel qib siv nyob rau hauv kev lag luam automotive. Cov qib no tau muab cais raws li lawv cov khoom thiab cov yam ntxwv, xws li lub zog, ductility, thiab corrosion kuj. Nov yog qee cov qib txias-kuav los tiag steel siv hauv kev lag luam automotive:
Deep Drawing Quality (DDQ): Qhov txias-dov steel qib no yog qhov zoo tagnrho rau kev kos duab sib sib zog nqus, xws li kev tsim cov khoom siv tsheb xws li fenders, hoods, thiab qhov rooj. DDQ steel muaj cov qauv zoo heev, ua rau nws yooj yim rau cov duab tsis tawg lossis tawg.
Extra Deep Drawing Quality (EDDQ): EDDQ steel zoo ib yam li DDQ steel tab sis muaj kev tsim tau zoo dua. Nws yog feem ntau siv los tsim cov khoom siv hauv tsheb xws li roj tso tsheb hlau luam, roj lauj kaub, thiab kis kab mob.
Baking Hardenable (BH): BH steel yog tsim los rau kev ua kom tawv tawv, uas ua rau nws muaj zog thiab tawv. BH steel feem ntau yog siv los tsim cov khoom siv tsheb xws li lub qhov rooj thiab lub rooj zaum.
High Strength Low Alloy (HSLA): HSLA steel yog lub zog muaj zog, tsis tshua muaj hlau alloy uas muaj cov khoom siv zoo heev, suav nrog lub zog siab, toughness, thiab ductility. Nws yog feem ntau siv los tsim cov khoom siv tsheb xws li cov khoom ncua kev kawm ntawv, chassis, thiab lub log.
Cold rolled steel khoom zoo kev ruaj ntseg:
Tshwj xeeb steel hom automotive steel:
1. Ultra sib sib zog nqus nqus IF txias dov steel phaj
Nyob rau hauv ultra-low carbon steel nrog carbon Tsawg dua los yog sib npaug rau 0.008%, ntxiv cov nyiaj txaus ntawm cov pa roj carbon monoxide thiab nitrogen tebchaw los tsim cov ntsiab lus titanium thiab niobium, kom cov pa roj carbon thiab nitrogen atoms hauv cov hlau yog tag nrho. tsau rau hauv carbon thiab nitrogen tebchaw (Ti (C, N), Nb (C, N)), tsis muaj interstitial atoms nyob rau hauv steel, hom hlau no hu ua "Interstitial Free Steel", abbreviated li IF steel.
2. Txias-rolled high-strength steel phaj
Sib sib zog nqus-draw txias-kuav los tiag steel daim hlau yog tsuas yog ntxiv dag zog nrog phosphorus. Qhov no yog vim lub zog muaj zog muaj peev xwm ntawm phosphorus, uas yog kwv yees li 7 npaug ntawm silicon thiab 10 npaug ntawm manganese. Ntxiv 0.1% phosphorus rau cov hlau muaj tib lub zog ntxiv rau kev ntxiv 0.7% silicon lossis 1.0% manganese. Qhov no tuaj yeem txuag tau ntau ntawm cov ntsiab lus alloying, uas tsis tsuas yog txo cov nqi ntawm cov hlau, tab sis kuj tsis ua rau cov hlau ntxiv nrog ntau cov ntsiab lus Alloying (Si lossis Mn) txo cov plasticity ntawm steel phaj.
3. Cold-dov dual-theem steel phaj
Raws li lub zog nce, lub elongation ntawm steel phaj txo. Yuav kom tau txais cov phaj steel nrog lub zog siab thiab cov yas zoo, cov qauv zoo tshaj plaws yuav tsum yog ferrite (siab plasticity) + martensite (siab zog). Nws yuav tsum tau hais tias lub martensite tsis rhuav tshem qhov txuas ntxiv ntawm deformation ntawm cov qauv yooj yim (ferrite) thaum lub sij hawm stamping. Lub martensite yuav tsum yog cov kob-puab. Hom ferrite + martensite steel yog hu ua dual-theem steel.
4. Nto kho steel phaj (tuaj yeem ua ke nrog lub zog siab steel phaj)
(1) Kub-dip galvanized thiabelectro-galvanized steel ntawv; (2) Alloyedkub-dip galvanized steel ntawv(abbreviated li GA steel ntawv); (3) Zn-Ni alloy electro-plated steel nplooj ntawv; (4) Ob txheej Zn-Fe alloy electro-plated steel nplooj ntawv; (5) Nyias zaj duab xis organic composite steel phaj; Cov txheeb cais qhia tau hais tias tus nqi corrosion thiab tsis ua hauj lwm tus nqi ntawm cov tsheb tsim nrog kub-dip galvanized steel los xij tsuas yog 1/3 ntawm cov uas ua nrog cov ntawv hlau zoo tib yam. Nws yuav pom tseeb dua thaum lub tsheb qhov kev pab cuam lub neej ntev.
5. Kub dov pickled steel phaj
Cov txheej txheem ntau lawm ntawm kub-dov hlau phaj yog luv luv thiab tus nqi qis. Cov hlau phaj muaj lub zog siab thiab zoo elongation. Lawv tsuas yog siv los tsim cov tsheb thav duab, lub log, cov khoom sib txuas, chassis thiab cov khoom siv. Cov phaj hlau no tau muab los ntawm hydrochloric acid, online smoothed thiab oiled. Qhov saum npoo ntawm cov hlau phaj yog du thiab du, thiab qhov tseeb qhov tseeb yog siab. Nws yog hu ua kub dov pickled steel phaj. Nws tuaj yeem siv los hloov qee qhov txias-kuav los tiag steel daim hlau los tsim cov khoom siv thiab cov khoom sib sib zog nqus kom txo cov nqi tsheb.
