1.Dab tsi yog vim li cas rau deformation?
Lub deformation tom qab leveling, txawm tias nws yog kab rov tav wrinkling, ntsug dabtsi yog khoov, los yog kab pheeb ces kaum warping, yog qhov tseem ceeb ntawm qhov tsis sib xws hauv cov kev ntxhov siab sab hauv ntawm cov khoom. Thaum cov txheej txheem leveling (xws li straightening los yog txiav) lov qhov qub kev nyuaj siab tshuav nyiaj li cas, thiab cov khoom nws tus kheej tsis muaj txaus "kuj", nws yuav tso tawm qhov kev nyuaj siab los ntawm deformation.
2.Dab tsi yog qhov ua rau kab rov tav wrinkles thiab creases?
Internal ua rau (khoom):
- Lub zog tsis muaj zog lossis cov nplej ntxhib: Cov khoom siv nws tus kheej yog "mos," thiab cov txheej txheem annealing tsis raug ua rau cov nplej ntxhib, ua rau tsis zoo rau deformation thiab yooj yim wrinkling thaum ncab.
- Kev pom ntawm cov qoob loo loj: Annealed qis- cov pa roj carbon steel muaj yield plateaus, ua rau yielding tam sim ntawd nyob rau hauv cov cheeb tsam thaum lub sij hawm uncoiling, tsim Lüders bands (tus qauv nto).
- Cov ntawv tsis zoo: Cov khoom xa tuaj muaj ntug waviness thiab nruab nrab waviness, qhia tias tsis sib xws hauv kev ntxhov siab.
- Interlayer adhesion: Thaum lub sij hawm annealing, cov khaubncaws sab nraud povtseg ntawm steel coil ua ke, ua rau cov yas deformation thaum uncoiling thiab tearing.
3.Yuav ua li cas peb thiaj tswj tau kab rov tav wrinkles thiab creases ntawm qhov chaw?
1. Re- tshuaj xyuas cov ntaub ntawv: Tshawb xyuas daim ntawv pov thawj zoo kom paub meej tias cov khoom siv zog ua tau raws li tus qauv. Rau siab - qhov yuav tsum tau muaj stamping qhov chaw, qhia meej txog kev siv cov ntawv hlau uas tsis muaj - tawm los platen lossis uas tau dhau los ua tiav thiab tempering.
2. Ua qauv txheej txheem annealing: xyuas kom meej tias qhov kub thiab txias annealing, lub sij hawm, thiab qhov txias txias yog tsim nyog kom tsis txhob coarse nplej thiab interlayer adhesion.
3. Tshawb xyuas cov duab ntawm cov khoom tuaj: Yog tias pom pom tseeb waviness nyob rau hauv cov khoom tuaj, sib tham nrog tus neeg muag khoom tam sim ntawd.
4.Dab tsi yog qhov ua rau mob - zoo li khoov, ib sab - nthwv dej, thiab warping?
Cov khoom siv sab nraud tuaj yeem: Tus ntoo khaub lig- ntu tuab ntawm cov phaj hlau tsis sib xws, nrog rau ib sab yog tuab dua li lwm qhov. Tom qab cov khoom no yog leveled, nws yuav zoo li tiaj tus, tab sis ib zaug qhov kev ntxhov siab tawm, lub ntug waviness yuav rov qab tam sim ntawd.
5.Peb tuaj yeem tswj nws ntawm qhov chaw li cas?
Ntsuas tus ntoo khaub lig-section: Yog tias tsis ntseeg, siv lub micrometer los ntsuas qhov tuab ntawm ob sab thiab hauv nruab nrab ntawm cov hlau phaj kom paub meej tias puas muaj cov duab zoo nkauj (thickness txawv> 0.5% -1%).
Cov khoom siv tu thiab ua haujlwm:
1. Txheeb xyuas cov khoom raug: Tsis tu ncua calibrate lub tshuab leveling kom ntseeg tau tias cov txheej txheem rau cov menyuam yog sib npaug thiab theem.
2. Txhim Kho Kev Cia: Cov phaj steel qib yuav tsum tau muab tso rau ntawm lub tiaj tiaj, cov ntoo qhuav qhuav, tsis txhob ncua kev ncua lossis kev cia ntev ntev, tshwj xeeb tshaj yog rau cov phaj nyias.
