Q: Qhov yuav tsum tau ua dab tsi txias-dov raw ua tau kom tau sib ntsib?
A: Tsis muaj hlau oxide teev rau saum npoo (tshem tawm los ntawm pickling tom qab kub dov);
Thickness kam pub tsawg dua los yog sib npaug ± 0.05mm (kub dov qhov tseeb cuam tshuam cov khoom txias ntawm cov khoom tiav);
Cov khoom siv tsis sib xws (zam kev sawb breakage lossis tsis sib xws rau thaum lub sijhawm txias ({}
Q: Tus txheej txheem npaj ua ntej dov txias?
A: {1. pretreatment:
Degreasing: Yog tias dov roj lossis cov paug tseem nyob ntawm qhov chaw sov, nws yuav tsum tau muab tshem tawm los ntawm cov zaub mov tsis muaj txiaj ntsig (xws li cov khoom tiav thiab cov khoom tiav lawm {}}
Ncaj Ncees: Ncaj Nraum Zej Zog thiab khoov ntawm lub phaj kub-dov (siv cov ntaub qhwv ncaj) kom ntseeg tau tias daim ntawv ncaj ncaj thaum tsis ua tiav.
{{02. pickling (yog tias cov khoom siv raw tsis yog pickled)
Lub Hom Phiaj: Tshem cov hlau oxide oxide (Fe₃o₄, Feo, thiab lwm yam ntawm lub phaj kub kom tsis txhob ua rau daim ntawv tsis zoo thaum dov lub sijhawm rolling.
Txheej Txheem: sulfuric acid pickling: soak hauv 50 ~ 80℃sulfuric acid acid;
Hydrochloric acid pickling: kev ntsuas kub siv 10%) ~ 15%), cov tshuaj tiv thaiv tau zoo dua rau cov kab txuas ntxiv;
Yaug thiab qhuav: tom qab pickling, yaug cov ntawv seem nrog dej huv, thiab tom qab ntawd qhuav nws nrog cov cua kub kom tiv thaiv xeb .
Q: Dab tsi yog cov kev dov thiab dov zeb hom?
A: {{1.} Ib Leeg-Brand Txias Rolling
Muaj feem xyuam nrog cov xwm txheej: cov khoom lag luam me me lossis cov khoom tshwj xeeb tshwj xeeb .
Cov Khoom Siv: Plaub-yob Reversible Rolling Zeb (Me Ua Haujlwm Dov taub lub taub
Cov yam ntxwv cov yam ntxwv: cov phaj steel yog dov rov qab thiab tawm nyob rau hauv lub rolling mill (pem hauv qab Rolling → rov qab dov), maj mam muab rho tawm;
Cov nqi them txo qis (cov tuab tuab txo cov rolling ntawm ib tus lej dov) feem ntau yog 10%, thiab tag nrho cov nyiaj txo tau mus txog 60% ~ 80% {4}
{{02. nruam multi-sawv ntsug txias (txias tandem dov)
Muaj feem xyuam nrog cov xwm txheej ntau lawm ntawm cov pa tuab txias-rolled daim hlau .
Cov Khoom Siv: 5 ~ {{{{1} sawv ntsug Tandem Rolling chav tsev, xws li balling yob thiab yob shifting tshuab).
Cov yam ntxwv ua: Hlau phaj tshaj los ntawm ntau tus sawv hauv ntu, txhua tus sawv ntsug ua tiav qee qhov kev txo qis, thiab tag nrho cov nqi txo tau tuaj yeem ncav ntev 70% ~ 90%;
Lub rolling ceev yog siab, thiab kev ua tau zoo yog 5 ~ 10 zaug uas ntawm ib qho kev sawv;
Q: Cov txheej txheem tseem ceeb tsis tau muaj cov txheej txheem txias thaum lub sijhawm txias?
A: Rolling Force: Lub zog dov ntawm ib qho sawv ntsug tuaj yeem ncav cuag txhiab tus tons, thiab lub zog dov ntawm ib qho muag ntawm lub colling txias yog feem ntau 500 ~ 2000 tons; Kev siv roj ntau dhau yuav yooj yim ua rau cov menyuam muaj cov menyuam hnav lossis cov phaj steel ntug cracking, uas yuav tsum tau ua kom zoo los ntawm cov menyuam cov ntaub thiab tswj hwm cov khoom siv
Rolling ceev: ib qho sawv ntsug qis-ceev dov yog qhov haum rau kev tswj-; txias dov rau high-ceev dov yuav tsum tau lub high-ceev nro tswj system {}}
Nro tswj: Thov nro nruab nrab ntawm cov sawv ntsug ntawm cov nplais rolling zeb thiab lub sij hawm nro qis> inhibiting qhov sib txawv thiab nthwv duab ntawm cov hlau phaj thiab txhim kho cov phaj nplaum;
Tension Tus nqi ntau: Cov roj av tsawg dua li 10% ~ 20% ntawm cov qoob loo muaj zog .
Q: Qhov zoo thiab cov kev txwv thiab cov txheej txheem txias txias txias?
A: Zoo
1. huab cua siab: tuab txoj kev zam tau ncav cuag ± 0.01 hli, nto roughness RA <1μm, ntsib cov kev xav tau ntawm kev tsim kho;
{{02. pa zog: ncaj qha txhim kho lub zog los ntawm kev ua haujlwm hnyav, txo cov nqi kho mob ua kom sov;
3.} muaj ntau yam kev ua tau zoo: yooj yim los ntawm annealing cov txheej txheem (xws li kev nqus cov txheej txheem sib sib zog nqus hlau, lub zog kom muaj zog hlau).
Kev txwv
{1. Kev Siv Hluav Taws Xob Loj: Rolling High Muaj Siab Rolling Force thiab Zog tau noj yog kwv yees li 2 ~ 3 zaug uas kub tau dov;
2. Ua haujlwm hnyav rau cov phiaj xwm: Cov phiaj hlau tsis txaus siab yog qhov nyuaj rau qhov sib sib zog nqus thiab xav tau kev pab txhawb ntxiv rau cov txheej txheem anealing;
3. Cov khoom lag luam loj tuaj yeem ncav cuag ntau lab ntawm Yuan, uas haum rau cov khoom loj loj.
