Ob qho tib si txias dov thiab kub dov yog cov txheej txheem rau kev tsim cov hlau los yog hlau daim hlau, thiab lawv muaj kev cuam tshuam zoo rau cov qauv thiab cov khoom ntawm cov hlau.
Lub dov yog tsuas yog ua raws li kub dov, thiab txias dov tsuas yog siv rau kev tsim cov khoom me me thiab cov nplooj ntawv.
Kub dov steel kauj yog siv los ua raw khoom rau txias dov.Tom qab pickling kom tshem tawm cov nplai oxide, qhov txias dov yog nqa tawm.Qhov ntsuas poob qis, yog li qhov kev ua haujlwm stamping yuav tsis zoo, thiab nws tsuas yog siv tau rau qhov chaw uas yooj yim deformation.Hard-dip coils tuaj yeem siv los ua cov ntaub ntawv raw rau cov nroj tsuag kub-dip galvanizing, vim tias kub-dip galvanizing units yog nruab nrog cov kab annealing.Qhov hnyav ntawm dov hard coil feem ntau yog 6 ~ 13.5 tons, thiab cov kub dov pickled coil yog txuas ntxiv dov ntawm chav tsev kub.Sab hauv txoj kab uas hla yog 610mm.Nws yog los ua cov ntawv hlau lossis cov hlau nplaum rau hauv ntau hom hlau los ntawm kev ua haujlwm txias xws li kev kos duab txias, txias khoov, thiab kos duab txias ntawm chav tsev kub.
Qhov zoo: kev sib sau ceev ceev, cov zis siab, thiab tsis muaj kev puas tsuaj rau txheej txheej, tuaj yeem ua rau ntau hom ntawv hlais kom haum rau kev siv.
Cov kev xav tau ntawm cov xwm txheej;txias dov tuaj yeem ua rau cov yas loj deformation ntawm cov hlau, yog li ua kom cov txiaj ntsig ntawm cov hlau.
Qhov tsis zoo: 1. Txawm hais tias tsis muaj cov yas kub compression thaum lub sij hawm tsim cov txheej txheem, tseem muaj kev ntxhov siab nyob hauv seem, uas muaj kev cuam tshuam tsis zoo rau tag nrho cov hlau.
thiab cov yam ntxwv ntawm lub zos buckling yuav inevitably muaj kev cuam tshuam;2. Cov style ntawm txias-kuav los tiag steel feem ntau yog ib qho qhib seem, uas ua rau dawb torsion ntawm seem
Kev nruj yog tsawg.Nws yog nquag torsion thaum khoov, thiab khoov-torsional buckling yog nquag tshwm sim nyob rau hauv compression, thiab torsional kuj tsis zoo;3. Txias dov
Cov phab ntsa tuab ntawm cov hlau yog me me, thiab cov ces kaum uas cov hlau txuas txuas tsis yog thickened, yog li muaj peev xwm tiv taus cov khoom hauv zos concentrated tsis muaj zog.
Vim tias nws tsis tau muab tshem tawm, nws cov tawv tawv yog siab heev (HRB yog ntau dua 90), thiab nws cov machinability yog qhov tsis zoo.Tsuas yog kev taw qhia yooj yim ntawm qhov qis dua 90 degrees (perpendicular mus rau coiling kev taw qhia) tuaj yeem ua tau.Hauv cov ntsiab lus yooj yim, txias-dov hlau yog ua tiav thiab dov los ntawm lub hauv paus ntawm kub dov coils.Feem ntau hais lus, nws yog txheej txheem kub dov → pickling → txias dov.
Txias dov yog ua tiav los ntawm cov ntawv kub dov ntawm chav tsev kub.Txawm hais tias qhov kub ntawm cov ntawv hlau yuav raug cua sov thaum lub sij hawm ua, nws tseem hu ua txias dov.Cold-dov coils tsim los ntawm qhov txias txias deformation ntawm kub dov muaj cov khoom siv tsis zoo thiab siab hardness.Lawv yuav tsum tau annealed los kho lawv cov khoom siv kho tshuab.Cov uas tsis muaj annealing yog hu ua hard-rolled coils.Hard-dov coils feem ntau yog siv los ua cov khoom uas tsis tas yuav khoov lossis ncab, thiab khoov rau ob sab lossis plaub sab nrog tuab ntawm 1.0 lossis tsawg dua.
