Kev tswj cov phab ntsa tuab ntawm cov yeeb nkab steel yog ib qho nyuaj rau kev tsim cov yeeb nkab steel. Cov kev ntsuas uas txhim kho cov phab ntsa thickness hauv kev tsim khoom feem ntau suav nrog cov hauv qab no:
1. Thaum tshav kub kub
Cov cua sov yuav tsum tsis sib xws thiab qhov kub thiab txias yog txwv tsis pub. Ua kom du thiab maj mam nce txhua qhov nce, thiab qhov siab tshaj plaws nqa qhov kub tsis tshaj 30 degree C.
2. Concentrated roller
Txiav txim siab seb qhov kev teeb tsa ntawm lub plawv cov menyuam nyob rau hauv qhov chaw, kho qhov chaw ntawm cov tub ntxhais uas muaj feem xyuam nrog, lub kaum sab xis qhib, thiab qhov qhib qhov loj ntawm txhua qhov txav. Qhov nruab nrab ntawm cov tub ntxhais cov menyuam yuav tsum nyob ntawm txoj kab dov.
3. Rolling center kab
Xyuas kom tseeb tias qhov nruab nrab ntawm lub suab dov tshuab yog raws li qhov nruab nrab ntawm lub perforation, thiab tsis txhob "sab sauv" los yog "down dov", kom lub raj xa dej dawb paug yog uniformly stressed thaum perforation.
4. Cov cuab yeej dov
Rolling cov cuab yeej xws li hnav, coj phaj, thiab yob yuav tsum tau hloov raws sijhawm.
5. Kev txhim kho cov cuab yeej dov
Qhov nruab nrab ntawm cov menyuam nyob deb thiab kev taw qhia deb yuav tsum nyob ntawm txoj kab dov. Lub hauv paus kab ntawm kev taw qhia kev ncua deb thiab cov menyuam nyob deb yog nyob rau hauv kab nruab nrab ntawm cov dov dov, uas yog, lub sab sauv thiab qis rollers yog sib npaug, thiab sab laug thiab txoj cai qhia yog sib npaug.
6. Ncej saum tus pas nrig
Lub perforated sab saum toj pas nrig feem ntau xaiv los ntawm cov phab ntsa tuab nrog φ108mm-φ114mm, phab ntsa thickness yuav tsum Ntau tshaj los yog sib npaug rau 25mm thiab niaj hnub phab ntsa thickness.
7. Qhov txav txav txav txav txav
Cov tub ntxhais pas nrig yuav tsum tau ua tiav nrog cov phab ntsa tuab nrog cov phab ntsa tuab. Rau qhov tshwj xeeb me me, cov pas nrig tseem tuaj yeem hloov tau los ntawm cov khoom xyaw. Cov phab ntsa tuab thiab cov khoom siv nrog cov phab ntsa tuab tuaj yeem txo qhov tshwm sim ntawm kev khoov thiab deformation ntawm cov tub ntxhais pas nrig, uas tuaj yeem txhim kho cov phab ntsa tuab qhov tseeb ntawm cov yeeb nkab steel.
8. Qhov tseeb ntawm cov core stick
Cov ntsiab lus ntawm tus pas nrig tseem ceeb yog qhov loj. Feem ntau, sab nraud ntawm lub tsheb feem ntau yog siv los rhuav lub qhov ncauj vuam, lossis cov khoom siv ntev yog nqa ncaj qha. Qhov tseeb machining sab nraud ntawm cov tub ntxhais pas nrig yog tswj ntawm ± 0.1mm, thiab qhov ncaj degree sib txawv ntawm cov tub ntxhais pas nrig tsis tshaj 5 hli. Thaum lub sij hawm vuam, ib seem ntawm ob-section pas nrig yog muab tso rau hauv ib tug precision-processing muag khoom los nrhiav kom tsis txhob tag nrho cov ncaj degree deviation tshwm sim los ntawm vuam.
9. Txhim kho cov txheej txheem
Txhim kho cov txheej txheem los tiv thaiv qhov nruab nrab ntawm thinning thiab phab ntsa tuab los ntawm kev ua kom muaj kev tswj hwm ntawm kev tswj ntau yam, thiab txhim kho phab ntsa thickness raug.
