Tsis zoo thiab kev kho mob ntawmtxias kos steel yeeb nkabyog raws li nram no:
1, folding: rub lub kaw lus, txias rub cov yeeb nkab steel hauv thiab sab nraud ua ncaj nraim los yog kauv kev taw qhia ntawm folding, qhov tshwm sim ntawm lub zos los yog ntev dhau ntawm cov yeeb nkab.
Qhov ua rau: qhov saum npoo ntawm cov khoom siv yeeb nkab yog folded los yog cov khib nyiab tiaj tus, abrasions loj thiab tawg ntawm lub raj zeb kho ntawm cov ces kaum lossis nam piv (H / b) tsis txaus.
Kev tiv thaiv thiab tshem tawm txoj kev: nruj raws li cov txheej txheem uas yuav tsum tau muaj cov khoom sib tsoo.Cov khoom siv yeeb nkab tsis raug muab tso rau hauv kev ua haujlwm tiv thaiv.Qhov zoo perforation kub xaj nruj zoo.

2, qhov loj ntawm kev kam rau siab (nrog rau cov phab ntsa thickness ntawm ultra-tsis zoo, tsis sib luag phab ntsa thickness, txoj kab uas hla ultra-poor, oval) txoj kab uas hla tshaj qhov txawv ntawm tus qauv sib txawv, nyob rau hauv tib seem ntawm phab ntsa ntawm nyias, tuab, txoj kab uas hla ntawm qhov me me axis sib txawv tshaj li tus qauv yuav tsum tau ua.
Qhov ua rau: 1, ntawm kev xaiv pwm xaiv tsis yog xwb, lossis Rui stick (tus qauv sab hauv) kho tsis raug.2 cov qauv tsim nyob rau hauv cov pwm tsim thiab tsim cov khoom tsis tsim nyog lossis hnav tsis zoo lossis tawv txaus ua rau deformation hnav.3, kev kho cua sov rau lub sijhawm ntev thiab kub siab.Kev ua haujlwm tsis sib xws lossis kev kho cua sov.4, kev hloov pauv hauv txoj cai ntawm phab ntsa khoob rub kom zoo, rub tab kev npaj tsis tsim nyog.5, txias drawn steel yeeb nkab straightening squashed txoj hauj lwm phaib gage tsis yog xoom, loj yuam kev.
Kev tiv thaiv thiab tshem tawm txoj kev: 1, tsim kom raug thiab tsim thiab xaiv extubation pwm.2, kev ua kom raug ntawm kev kho cua sov, cov cua sov tsis sib xws.3, Kho lub leveler kom raug, feem ntau proofreading extubation tshuab qhov chaw thiab ntsuas cov cuab yeej.4, raug thiab tsim nyog kev npaj rub lub watchmaking tswv ntau hom hlau, txoj cai ntawm kev nce los yog txo qhov sib txawv specifications steel yeeb nkab phab ntsa.5, ovality tsis muaj kab sib chaws, txiav txim siab raws li cov khoom tsim nyog, ovality tawm ntawm kab tuaj yeem rov ncaj, recectable hauv zos ovality outrageous.

3, qhov kev pab cuam nthuav tawm: txias drawn steel yeeb nkab nto ntawm longitudinal linear khawb hu ua zoned Road.Zoned ib ncig ntawm qhov sib txawv ntawm qhov ntev, hnav qhov nqaim, ntau qhov ditch zoo li pom ditch.
Qhov laj thawj: 1, lub rooj sib dhos tsis du, tawg lossis pob txha hlau.2, lub hammerhead hloov ib feem ntug thiab cov ces kaum, hnav cov cuab yeej.3, Owe pickling lossis capillary residual oxide nplai.4, grease, phosphating, saponification txheej txheem ua haujlwm kom raug.5, sab hauv thiab sab nrauv pwm, puas lossis hnav tsis zoo.6, qhov nruab nrab annealing tsis sib npaug, tus nqi deformation tsis txaus.
Kev tiv thaiv thiab tshem tawm txoj kev: 1, txhim kho qhov zoo ntawm extubation pwm nto.2, Oxide pickling, yaug, txheej txheej txheej.3, hammerhead hloov nyob rau hauv ib feem mus rau rounded ces kaum.4, Kev tshuaj xyuas hauv av ntawm cov pwm thiab qhov chaw ntawm cov yeeb nkab steel, txheeb xyuas cov teeb meem thiab kev kho raws sijhawm.

4, co qauv: txias drawn steel yeeb nkab nto ntawm qhov ntev yog lub nplhaib spiky yoj los yog yoj-los ntawm tib txoj kev npaj, hauv zos los yog ntev dhau los tshwm nyob rau saum npoo ntawm cov yeeb nkab steel sab hauv thiab sab nraud.
Qhov ua rau: 1, kev ua haujlwm tsis sib xws tom qab kev kho cua sov, lubrication tsis zoo, saponification tsis sib xws.2, Rui nyias pas nrig, Rui lever rub system tsim elastic deformation los ntawm jitter.3, cov qauv tsim tsis tsim nyog nkag lub khob hliav qab lub kaum sab xis ib yam nkaus, yog li cov hlau tuag qhov chaw sib cuag me me dhau, yog li cov cua ntsawj ntshab system deformation tsis ruaj khov nto jitter.
Kev tiv thaiv thiab kev tshem tawm txoj kev: 1, cov txheej txheem ua haujlwm yuav tsum ua kom ua tiav qhov kev ua haujlwm zoo sib xws.2, noj ib qho zoo ntawm pickling, phosphating, saponification.Cov ntawv teev npe sib txawv ntawm cov duab kos duab.3, qhov raug xaiv ntawm qhov loj Rui pas nrig.

5, rub concave: steel yeeb nkab longitudinal kev taw qhia, phab ntsa yog strip sab hauv kev nyuaj siab, nws ntev tsis muaj cai.
Qhov laj thawj: 1, tsis yog-cov pob txha pob txha pob txha pob txha pob txha (cov pob txha tsis muaj) cov yeeb nkab steel nyias, txo qis ntau dhau.2, qhov kawg ntawm cov yeeb nkab steel rauj npoo thiab cov ces kaum, qhov kev hloov pauv folds.3, lub zos nyias phab ntsa ntawm cov yeeb nkab khoom (xws li kev sib tsoo kho taw tes).
Kev faib tawm los ntawm kev txo qis rau kev tiv thaiv thiab tshem tawm txoj kev: 1, khoob rub lub nyias-walled raj.2, hammerhead kawg npoo thiab folds.3, ib feem ntawm qhov chaw ntawm cov khoom siv yeeb nkab, kev ntxuav, qhov sib piv yuav tsum tsim nyog.

6, Cracking (diastema): txias drawn steel yeeb nkab nthuav dav nkag mus rau hauv phab ntsa ntawm longitudinal split, los ntawm ntev-localized cracking.
Qhov laj thawj: 1, siab dhau heev lawm, txawm tias rub dhau ntau dhau, cov khoom siv raj ua haujlwm hnyav hnyav, tshwj xeeb tshaj yog khoob Stubbs.2, Kev kho cua sov tsis zoo, cov yeeb nkab saum npoo ntawm cov khoom siv yas ua txawv rau reactive ua hauj lwm hardening tsis tag nrho tshem tawm.3, steel tube kos duab tshav kub kho raws sijhawm.4, tsis tshua muaj plasticity steels yog yooj yim rau tawg.
Kev tiv thaiv thiab tshem tawm txoj kev: 1, kev npaj tsim nyog rau rub lub tab.2, alloy steel raj thiab rub txawm rub cov yeeb nkab steel los kho cua sov kom raws sijhawm.3, kev kho cua sov raws li cov txheej txheem yuav tsum tau ua, qhov cua txias yuav tsum tswj kom tsim nyog, nws qhov kev ua tau zoo txawm tias tshem tawm kev ua haujlwm nyuaj.

7, ib yam nkaus thiab pickling: txias drawn steel yeeb nkab nto ua rau lub qhov zoo li sesame-zoo li cov kab nrib pleb, qhov hnyav ntawm qhov sib txawv ntawm sab nrauv loj dua sab hauv.
Qhov laj thawj: 1, steel yeeb nkab nto oxide thickness tsis sib xws, xoob thiab khov kho.2, lub sijhawm pickling yog ntev heev.3, pickling concentration yog tsawg, cov ntsiab lus siab ntawm ferrous sulfate nyob rau hauv cov ntaub ntawv ntawm high pickling kub yooj yim ua ntej pickling.4, acid concentration tsis sib npaug, cov tshuaj tsis ntws, corrosion tsis sib xws.
Kev tiv thaiv thiab tshem tawm: 1, kom ua tiav cov txheej txheem pickling kom zoo.2, kev kho cua sov ua haujlwm, txhawm rau tiv thaiv qhov tsis sib xws ntawm cov yeeb nkab steel nto oxide nplai.Ua tib zoo siv lub tshuab ntxhua khaub ncaws ntxhua khaub ncaws, tshuaj xyuas hauv av, kom tsis txhob over-pickling.

8, Cold drawn steel yeeb nkab nto mus rau hauv ib daim ntawm zoo dot-zoo li pits, pitting: (Ma nto pits) ib feem los yog tas li ntawm cov hlau nto.
Qhov laj thawj: 1, kev kho cua sov ua rau cov tawv nqaij tawv tuab heev, nias rau hauv cov tawv nqaij ncaj ncaj tev thiab pitting.2, tom qab pickling residual oxide nplai los yog saponification kua av, pitting rub.3, tube pickling, nres ntev dhau los xeb tshwm sim los ntawm lub ntsej muag pockmarked.4, lub raj nplaim roj, kev kho cua sov coalesce rau hauv cov roj taw tes tua hluav taws kub pockmarked ntsej muag.
Kev tiv thaiv thiab tshem tawm txoj kev: 1, kev ua kom raug ntawm cov cua sov kho qhov cub nruab qhov system.2, ua raws li qhov nrawm nrawm.3, Pickling ua ntxuav, tsis txhob tshuav daim duab kos raws sij hawm tom qab pickling.

9, Drawing Fracture: Kev kos duab tsim lub suab txawv txawv, tsis muaj cov nyhuv lubrication, pwm Rui nap strain tube nqus tshuab load nce, qhov qis dua.
Ua rau: 1, ua ntej cov txheej txheem tsis ua raws li cov kev cai, teeb meem ntawm qee yam, xws li pickling carbonization (hydrogen embrittlement), tshwm sim los ntawm txias-draw steel raj kos duab tawg.2, phosphating tsis yog mus txog qhov kev hloov pauv (laus dhau) ua rau cov phosphate txheej tawm ntawm cov duab tsis tiav saponification lub hom phiaj, uas tsim cov suab nrov txawv txawv tsis tu ncua.3, saponification kub yog tsawg dhau los yog siab dhau, qhov concentration tsis txaus, qhov tsis txaus ntawm saponified adsorption lossis xab npum yog acidified poob ntawm lubricating nyhuv.4, phosphating ua pwm Rui thiab lub raj phab ntsa puas, nqus cov load nce.
Kev tiv thaiv thiab tshem tawm txoj kev: 1, cov txheej txheem nruj me ntsis, kom tswj tau cov concentration ntawm pickling, kub, lub sij hawm, ntxuav yaug, hloov dej.2, tsis tu ncua xyuas ntawm phosphating tov ntawm tag nrho cov acidity, dawb acidity, tsim ib tug txaus npaum li cas ntawm phosphate zaj duab xis.3, tswj qhov kub ntawm saponification, concentration, ua kom zawj xab npum huv si.
