Hauv kev xav tau ntawm cov qauv kev tsim vaj tsev, qhov tseeb ntawm cov khoom tsim khoom yog qhov tseem ceeb raws li qhov zoo ntawm cov khoom siv raw. Tsis ntev los no, GNEE tau ua tiav qhov tseem ceeb tshiab hauv kev ua haujlwm qis - alloy siab - lub zogQ355B steel qauv, ua tiav kev xa cov khoom siab -precision bent Cheebtsam uas ua tau raws li cov qauv nruj tsim los ntawm cov tshuab hnyav thiab cov chaw tsim kho vaj tse.
Dab tsi yog High -Strength Q355B Cov Qauv Hlau?
Q355B yog ib qho qis- alloy, siab - lub zog steel qauv txhais los ntawm Suav teb chaws tus qauv GB/T 1591, uas muaj qhov tsawg kawg nkaus tsim tawm lub zog ntawm 355 MPa (muaj feem xyuam rau cov phaj nrog lub thickness tsawg dua lossis sib npaug li 16 hli). Raws li niaj hnub, siab -kev ua tau zoo hloov kho rau Q345B, nws qhia tau tshwj xeeb weldability, toughness, thiab durability nyob rau hauv kev tsim kho, choj engineering, thiab hnyav machinery manufacturing.

Qhov Kev Sib Tw ntawm Khoov Siab -Lub Zog Q355B Cov Qauv Hlau
Kev khoov ntawm Q355B steel tsis yog ncaj nraim li khoov cov pa roj carbon zoo tib yam. Vim nws lub zog siab thiab hardness, cov txheej txheem nquag nthuav tawm ntau yam kev cov nyom:
Springback Control
Thaum tso tawm lub siab, Q355B steel nthuav tawm qhov tshwm sim tseem ceeb "caij nplooj ntoos hlav" tshwm sim. Txhawm rau kom ntseeg tau qhov tseeb qhov tseeb nyob rau hauv qhov kev cia siab, kev ntsuas nyiaj txiag meej yog qhov tseem ceeb.
Nto Integrity
Yog tias tsis siv lub vojvoog khoov uas tsim nyog tsis ua haujlwm, hom siab - cov khoom siv phaj muaj zog no yog qhov ua rau muaj kev cuam tshuam loj rau micro- tawg ntawm nws sab nrauv nro.
Kev Cai nruj nruj
Txoj haujlwm khoov tam sim no suav nrog Q355B siab- lub zog steel phaj nrog lub thickness ntawm 20 hli thiab ntev li ntawm 6 txog 12 meters. Kev ua haujlwm dabtsi yog khoov yuav tsum tau ua kom tiav ib txhij ntawm plaub qhov sib txawv radii -R200, R255, sab hauv R90, thiab sab hauv R68-nrog cov kev cai nruj heev.
Tsis tas li ntawd, tag nrho cov workpieces yog symmetrical Cheebtsam, yuav tsum tau ib leeg, nruam 3-meter khoov thoob plaws qhov dav ntawm cov khoom. Ntxiv mus, ib zaug khoov, lub workpieces tsis tuaj yeem raug rho tawm ncaj qha los ntawm cov khoom siv khoov; Qhov kev txwv no tsis yog tsuas yog ua rau kev tswj xyuas qhov tseeb exponentially nyuaj dua tab sis kuj qhia txog kev nyab xeeb tseem ceeb thaum lub sij hawm tsim khoom thiab hoisting theem.
Advanced Bending Processing Technology ntawm Q355B Cov Qauv Hlau
Txhawm rau kov yeej cov kev cov nyom uas tau hais los saum no, GNEE ntiav cov xeev - ntawm --art 2,000-tuj precision dabtsi yog khoov tshuab thiab cov cuab yeej laser txiav. GNEE cov txheej txheem tsim khoom yog tsim los xa cov txiaj ntsig tseem ceeb hauv qab no:
✅ CNC Precision Control:GNEE's multi-axis CNC system cia li them nyiaj rau deflection thaum lub sij hawm dabtsi yog khoov, xyuas kom meej tias -txawm rau workpieces mus txog 12 meters nyob rau hauv ntev- lub dabtsi yog khoov cov ces kaum nyob rau hauv zoo meej ncaj thiab zoo ib yam ntawm kawg mus rau qhov kawg.
✅ Springback Compensation:Los ntawm kev siv lub tshuab ntsuas lub kaum ntse ntse laser siab, GNEE tuaj yeem suav qhov tseeb ntawm cov khoom siv Q355B hauv lub sijhawm. Qhov no tshem tawm tag nrho cov txheej txheem tedious ntawm phau ntawv kho thiab zoo txo cov khoom pov tseg.
✅ Kev tiv thaiv nto:GNEE ntiav cov txheej txheem tshwj xeeb tuag thiab zaj duab xis- tiv thaiv kev khoov los xyuas kom meej tias qhov chaw ntawm Q355B daim hlau tseem tsis pub muaj dents thiab khawb thoob plaws hauv tag nrho cov txheej txheem.
Kev siv ntawm Q355B Cov Qauv Hlau Khoov Qhov Chaw
Lub siab -precision khoov Q355B qhov tam sim no tau muab tso rau hauv:
Crane Boom Tshooj(High -lub zog telescopic qauv).

Yuav ua li cas kom tsis txhob tawg ntawm qhov khoov thaum ua Q355B?
Tus yuam sij yog tswj qhov tsawg kawg nkaus khoov vojvoog thiab sim khoov perpendicular mus rau dov kev taw qhia (transverse). Tsis tas li ntawd, chamfering lossis deburring cov npoo ntawm lub phaj ua ntej khoov tuaj yeem txo qhov kev pheej hmoo ntawm kev tawg.
Dab tsi yog qhov pom zoo yam tsawg kawg nkaus khoov vojvoog (R) rau Q355B?
Nws yog feem ntau pom zoo tias qhov tsawg kawg yog dabtsi yog khoov vojvoog R Ntau dua lossis sib npaug rau 1.5t(qhov twg tyog phaj thickness). Rau cov phaj tuab (tshaj 20mm), nws raug nquahu kom nce qhov no rau 2t los yog siab dua kom muaj kev nyab xeeb ntawm cov qauv.
Puas yog khoov hloov cov khoom siv ntawm Q355B?
Txias bending ua rau ua hauj lwm hardening nyob rau hauv qhov khoov cheeb tsam, uas ua rau kom lub zos hardness tab sis me ntsis txo ductility. Ntev npaum li lub vojvoog khoov yog qhov tsim nyog, tag nrho cov qauv ntawm lub zog yuav tsis raug cuam tshuam.
