Cov hom kev kho ntawm cov khoom tsim tawm los ntawm peb lub tuam txhab (Sichuan Huitai Tshwj Xeeb Metals Co., Ltd.) muab faib ua cov hauv qab no. Thov saib cov hauv qab no ua ntej xaj.
1.Brack nto
- Kub muag dub
① Xim: lub saum npoo yog xim dub lossis tsaus xim av. Qhov no yog vim thaum lub sijhawm kub rolling txheej txheem, cov hlau nyob saum npoo ntawm cov hlau bar reacts nrog oxygen nyob rau hauv cov txheej txheej ntawm oxide nplai.
② Qhov saum npoo yog ntxhib, nrog pom tseeb dov textures, uas yog cov traces sab laug los ntawm cov txheej txheem kub kub. Cov ntsiab lus no tau faib raws qhov ntev ntawm cov hlau bar thiab yog tsim tawm thaum nws tau dov los ntawm cov yob ntawm cov rollers ntawm siab kub.
③ Cov qauv raug: Daim duab zuag qhia tag nrho yog cov tsis tu ncua, tab sis piv nrog cov khoom tawge-txheej txheem ntawm not-rolled dub-skinned steel-cov hlau nplaum me me yog tsawg. Lub taub loj rau siab yog + / {4 4}} mm, thiab qhov ntev kev rau siab yog + +} mm.
Khij hauv qab daim duab ntawm kub dov dub saum npoo bar hauv qab no rau kev hais txog:
- Forged Dub
Xim Daws: Zoo ib yam li kub-dov dub steel hlau tuav, nws nto yog xim dub lossis tsaus grey vim oxidation. Qhov oxide txheej no yog tsim thaum lub sijhawm forging cov txheej txheem cua sov thiab tuaj yeem tiv thaiv cov hlau hauv sab hauv rau qee yam.
② Cov nplaim dej: Cov nplaim muaj cov cim tsis pub ntawd tshwj xeeb. Cov ntsiab lus no yog qhov tsis xwm yeem thiab cov ntxhib. Lawv yog cov txheej txheem sab laug los ntawm cov hlau ntws thiab deformation thaum lub sijhawm forging. Lawv faib tawm tsis muaj txoj cai pom tseeb thiab cuam tshuam tau txawv ntawm cov ntaub ntawv sau.
Cov yam ntxwv zoo cov yam ntxwv: Daim duab zuag qhia tag nrho yog ze dua rau qhov zoo tshaj plaws ntawm qhov zoo tshaj li qhov kub-dov dub steel hlau bar. Cov txheej txheem forging ua rau cov hlau bar muaj cov ncaj zoo dua thiab feem ntau tsawg dua ntawm-ntawm-kev sib tw. Txawm li cas los xij, muaj qee qhov me me tsis sib xws hauv qee qhov chaw, uas tshwm sim los ntawm qhov chaw ntawm kev zam txim tuag lossis qee yam hauv kev ua haujlwm tsis zoo.
④ Qhov kev ua siab ntev yog -0 / +5 hli.

2.Preeed nto
Show nto: Tom qab cov txheej txheem tev, cov oxide nplai thiab impurities nyob rau saum npoo ntawm steel bar tau muab tshem tawm, nthuav qhia lub ntsej muag ci. Qhov ntxhib yog loj, thiab cov xim tseeb ntawm cov hlau tuaj yeem pom meej meej, feem ntau yog nyiaj grey lossis greyish dawb.
② Qhov loj me: Cov txheej txheem raug yog tuaj yeem tswj qhov taub thiab lwm qhov ntev ntawm cov steel bar, thiab cov roundness yog qhov zoo. Qhov kev tawm tsam lub nroog feem ntau yuav tswj tau ntawm ± 2mm lossis txawm me dua, uas tuaj yeem ua tau zoo dua ua tau txoj kev ua haujlwm siab.
Cov kab ncaj ncaj: tus steel bar feem ntau undergoes ncaj thiab lwm cov txheej txheem ua ntej ntaub ntawv ncaj ncees yog qhov zoo, thiab tus curvature feem ntau tsis tshaj qhov txheej txheem tshwj xeeb. Piv txwv li, tus curvatined rau ib lub 'meter' tsis tshaj 1mm, uas muab rau tib neeg ncaj thiab tsis ntev los visualual.
Pom tau cov cim ua duab pom tseeb tuaj yeem pom ntawm cov tsos ntawm tus hlau bar.

3.Qhov machined (ntxhib tig) nto
Xim Xim: Cov saum npoo nthuav qhia qhov kaj metallic luster.
② Cov kab tig mus: Cov nplaim tau muab kauv tsis tu ncua, uas yog ncaj qha lossis ncaj, uas yog cov cim tsis tu ncua sab laug los ntawm tig cov cuab yeej thaum lub sijhawm txiav.
③ Qhov tseeb: Qhov tseeb qhov tseeb yog qhov tsis tshua muaj qis, thiab lub taub ntev yog feem ntau yog puag ncig ± 1mm.

4. Muv chaw muab saum npoo (tiav kev hloov)
① Cov xim saum npoo yog cov khaub ncaws txawv thiab zoo ib yam, qhia cov xim ntuj ntawm cov hlau, feem ntau yog nyiaj grey lossis greyish dawb. Tsis muaj qhov pom tseeb oxidation pom lossis lwm yam xim sib txawv, thiab nws muaj qhov pom kev zoo. Tag nrho cov tsos yog huv thiab zoo nkauj.
② Tsis tshua muaj kev sib tw ntub dej: precision tig tuaj yeem txo tau cov rougness saum npoo ntawm cov hlau bar, feem ntau txog li {2}}. 8μm. Qhov saum npoo yog du thiab muag heev, thiab lub qhov muag liab qab tuaj yeem pom cov cim riam pom tseeb. Nws pom tau tias du thiab tsis muaj kev graininess.
③ Qhov tseeb siab qhov tseeb: Txoj taub siab ntev yuav ua rau tswj nruj me ntsis hauv ± {0}}. 5 hli. Lub roundness yuam kev yog tsawg heev, feem ntau tsis tshaj 0.01mm. Cov cylindricity kuj tseem tuaj yeem tswj tau nyob rau hauv ib qho me me, uas tuaj yeem ua tau raws li cov cai ntawm cov kev sib dhos siab thiab siv.
Puab ca thiab du kawg: qhov xaus tau ua kom zoo, tiaj tus, tsis muaj qhov tseeb, thiab kev hloov pauv nrog lub cev tseem ceeb ntawm cov hlau loj.
