1.Yog qhov kev ua tau zoo tag nrho ntawm yob "zero fluctuation"?
Ib qho teeb meem tshwm sim nrog tswb- hom annealing yog qhov cua sov thiab cua txias ntawm lub nplhaib sab hauv thiab sab nraud ntawm cov hlau kauj sib txawv, ua rau qhov sib txawv hardness ntawm HRB 10-15 ntawm qhov pib thiab xaus. Cov kev hloov kho rau ib lub kauj thaum lub sij hawm stamping yuav ua rau tawg los yog wrinkling nyob rau tom ntej.
Nruam annealing, ntawm qhov tod tes, koom nrog tag nrho cov coil dhau los ntawm lub cub tawg ntawm tib qhov kub thiab txias profile, uas ua rau qhov sib txawv hardness tsawg dua los yog sib npaug rau HRB 5. Qhov no yog qhov yuav tsum tau ua ua ntej rau automated stamping kab uas tso cai rau "paub yam tsis hais txog hom coil."
2.Yuav ua li cas sib sib zog nqus - kos duab kev ua tau zoo raug kho?
Nruam annealing tso cai rau kev tswj kom meej ntawm kev ntxhib los mos los ntawm kev kub ceev thiab tshaj - kev laus kev kho mob:
Siab dua n-tus nqi thiab r- tus nqi: Tshwj xeeb tshaj yog rau IF steel (interstitial atom-dawb steel), nruam annealing ua kom muaj zog dua {111} kev ntxhib los mos, nrog r-tus nqi nce mus txog 2.5, piv rau Tsawg dua los yog sib npaug rau 2.
Tsis muaj yield plateau (tsis muaj kab hauv qab): Nruam annealing tau nyob rau hauv ib tug du online annealing kab nrog elongation tswj qhov tseeb ntawm ± 0.1%, tshem tawm tensile strain cim ntawm complex curved nto.
Ultra- cov nplej zoo thiab tsis sib xws: cua sov ceev tiv thaiv kev loj hlob ntawm cov qoob loo, ua rau cov qoob loo loj ntawm 7-8 (piv rau 5-6 hauv lub tswb nrov), ua rau lub ntsej muag du dua tom qab stamping (tsis muaj txiv kab ntxwv tev zoo nkauj).
3.Dab tsi txog siab -lub zog steel?
Rau siab -lub zog steels (DP, TRIP, MS) nrog lub zog ntawm 500 MPa los yog siab dua, tswb- hom annealing yog tsis yooj yim sua- alloying ntsiab yuav tsum tsim martensite / bainite thaum millisecond - qib txias. Nruam annealing yog tib txoj hauv kev rau cov qib siab siab -lub zog steels.
4.Koj tuaj yeem qhia qhov txawv ntawm "cov ntaub ntawv xa rov qab tsis tu ncua" ntawm ib sab?
Kev soj ntsuam saum npoo: Nruam annealing ua rau cov nyiaj tsis sib xws - grey xim, thaum tswb - hom annealing tshwm sim nyob rau hauv greyish -xiav los yog tsaus grey hue.
Tshawb xyuas daim ntawv pov thawj zoo: Cov kab txuas txuas ntxiv yuav raug cim "CAL" lossis "CAPL"; qee lub tuam txhab yuav cim nws li "tag nrho-hydrogen annealing" (tab sis ceev faj- tswb- hom furnaces kuj tseem siv tau tag nrho -hydrogen, tsuas yog muaj cov txiaj ntsig sib txawv).
Sample stamping: Nruam annealing ua tsis muaj kab; tswb- hom furnaces, yog tias qhov flatness thiab elongation tsis tswj kom zoo, tuaj yeem tsim 45℃kab txaij ntawm thawj lub thwj.
5.Qhov kev txwv yog dab tsi?
Alloy nqi rhiab heev: Nruam annealing yuav tsum tau ultra- carbon tsawg thiab micro-alloying (Ti, Nb), nce substrate nqi los ntawm 200-400 RMB / ton piv rau tswb hom rau cov ntaub ntawv.
Thickness range limitation: Typically ≤2.5mm; for thicker specifications (>3.0mm), nruam annealing kab tawm tsam kom ua tiav cov phaj ruaj khov, tseem yuav tsum tau tswb - hom furnaces.
Batch yooj: Nruam annealing ua haujlwm ntawm "kev sib dhos kab" hauv paus, nrog qhov tsawg kawg nkaus txiav txim kom muaj nuj nqis feem ntau Ntau dua lossis sib npaug li 100 tons; tswb- hom rauv tuaj yeem ua cov khoom me me ntawm 30 tons.
