Cov teeb meem zoo ntawm cov yeeb nkab steel feem ntau qhia tau hais tias nyob rau hauv qhov chaw oxide tuab, nto tawg, deg rov qab ntawm daim tawv nqaij, lub tshuab nqus tsev twj thiab lwm yam. tsim ib tug tuab thiab muaj zog adhesion, kub kub oxide.Tsis tsuas yog lub hav zoov ntawm oxide steel zoo nkaus li tsis zoo, kuj muaj feem xyuam rau kev siv hlau, uas yog tsis tso cai los ntawm tus qauv.Xws li oxides nrog cov xuab zeb dav dav yog qhov nyuaj rau kev tshem tawm, siv cov khoom siv los yog cov txheej txheem polishing kom tshem tawm.
Nto tawg tau tshwm sim nyob rau hauv cov kub-dov hlau, ib tug ntau carbon steel thiab hlau alloy steel hlab, feem ntau yog vim ceev ceev txias txheej txheem loj nto nro los ntawm cov residual kev nyuaj siab tshwm sim thiab tom qab.Cracks tsis yog ntog tawg (tsis muaj kev raug mob), tab sis nrog rau qee cov yam ntxwv ntawm cov kab nrib pleb yog tsim nyob rau hauv qhov kev xav tau ntawm ntau yam kev thov (xws li kub kub, tsis tshua muaj kub, ib puag ncig kev nyuaj siab corrosion cracking.etc.) mus rau ib qho twg, kom txo tau lub neej ntawm cov yeeb nkab steel.and txawm ua rau cov yeeb nkab tsis ua haujlwm.
Yog li ntawd, lub qub steel Hoobkas yuav tsum tau tawg cleared.Heavy tawv nto yog feem ntau nyob rau hauv txias-dov los yog txias drawn steel hlab, feem ntau yog vim lub billet nto los yog abrasive tshwm sim tsis deal.Heavy muaj yuav cuam tshuam cov tsos ntawm daim tawv nqaij zoo steel lub cuam tshuam rau kev siv cov yeeb nkab steel thiab tawg.txawm tsis hnyav.tab sis nyob rau qee qhov chaw tseem muaj qee qhov cuam tshuam.Txhim kho los ntawm kev ntxiv dag zog rau kev tswj hwm kev tsim khoom, txhim kho thiab tswj qhov zoo ntawm billet nto zoo thiab abrasive.Mechanical bruise yog ib feem ntawm cov teeb meem zoo tib yam, feem ntau yog tsim nyob rau hauv kev tsim, tuav thiab kev thauj mus los.Steel yuav tsim ib qho nqaij tawv ntawm cov qauv kev tsis sib xws, siv yog ib qhov chaw ntawm kev nyuaj siab concentration, tab sis kuj tsim notch rhiab heev.Piv nrog cov kab nrib pleb, mechanical defects bruised meej qauv, tsis muaj kev raug mob nyob rau hauv cov hlau, yog li tso cai rau ib co ntawm cov txheej txheem qhov tob muaj nyob, tab sis nyob rau hauv ib co ntawm cov rhiab heev rau daim ntawv thov tej yam kev mob , qhov tob tshaj ib qho nqi, los yog pob, yuav tsum yog hauv av kom tshem tawm txoj kev hloov mus kom du.
Qhov sib txawv ntawm qhov sib txawv feem ntau yog nyob rau hauv cov yeeb nkab steel ncaj, roundness, tsis sib luag thickness nam. Feem ntau, qhov ncaj siab kam rau ua rau kev siv cov yeeb nkab steel loj, tab sis qhov ncaj ntawm cov yeeb nkab steel tsim cov qauv tsim tawm, yog tias tus nqi teev dhau los yuav tsim. ib qho laj thawj rov qab los, thiab yog li ntawd, cov nroj tsuag tseem yuav tsum tau sau tseg.Roundness kam rau ua yuav cuam tshuam rau kev siv cov kav hlau steel.
Feem ntau nyob rau hauv cov pab pawg neeg ntawm lub vuam taub hau ntawm qhov tsis ncaj ncees lawm sab.Lawv roundness kam rau ua tsis ncaj ncees lawm sab vim dais muaj peev xwm ntawm welded pob qij txha yuav tsis tsuas yog txo, tab sis kuj tsim kev nyuaj siab concentration.Pob rau ntawm qhov chaw, ib co yeeb nkab roundness yuav raug kho.Sab nraud txoj kab uas hla steel yeeb nkab yog siv rau qhov cuam tshuam kev tsis ncaj ncees thiab kev sib haum xeeb ntawm kev sib haum xeeb.Non-uniform phab ntsa thickness feem ntau yooj yim tsis quav ntsej, thiab ntau cov qauv steel yeeb nkab tsis tau txhais meej meej.Yog tias qhov tsis sib xws ntawm phab ntsa tuab, yuav tsis tsuas yog ua rau qhov tsis ncaj ncees lawm ntawm kev sib koom ua ke, tab sis kuj tseem cuam tshuam rau kev deformation theem nrab (xws li steel yeeb nkab tsim yeeb nkab fittings) cuam tshuam tsis zoo.
