Ntsiab Cai
- - Pem hauv ntej nro thiab nraub qaum yog cov txheej txheem tseem ceeb rau silicon steel txias dov. Tsim nyog nro stabilizes dov raws li txoj cai, optimizes strip flatness thiab lowers dov siab; Cov kev tsis tsim nyog ua rau cov hlua khi tawg, yob slippage thiab cov duab tsis xws luag.
- - First-pass: txais yuav siab dua pem hauv ntej nro rau tuab tuaj strip; Rov qab nro yuav tsum koom tes nrog cov kab nro kom tsis txhob coil inter-layer slipping.
- - Kev hla nruab nrab: teeb rov qab nro siab dua qhov nro pem hauv ntej, qhov sib txawv nro tswj nyob ib puag ncig Tsawg dua lossis sib npaug li 30 kN thiab hauv qab strip tshwj xeeb nro los ntawm lub zog tawm los. Kev nro rov qab ntau dhau ua rau kev ua haujlwm-yob swb, tsis zoo ntawm qhov chaw thiab tswj tsis ruaj khov.
- - Qhov kawg-pass nro yuav tsum ua raws li kev nruj nruj ntawm cov kab nrib pleb txuas ntxiv, txhawm rau tshem tawm cov kab nrib pleb thiab qhov chaw puas hauv cov txheej txheem annealing.
1. Vim li cas Kev Nyuaj Siab Thaum Txias Rolling
Nyob rau hauv txias dov ntawm silicon steel (hluav taws xob steel) sawb, pem hauv ntej nro (ua ntej ntawm yob tom) thiab nraub qaum nro (tom qab yob tom) yog cov txheej txheem tseem ceeb. Kev tsim kho kom ruaj khov kho cov txheej txheem dov, txhim kho strip flatness (zoo li) thiab yob cov duab, thiab txo cov chav tsev dov siab. Kev teeb tsa tsis raug ua rau muaj kev puas tsuaj ntawm cov hlua khi, kev sib tsoo ntawm cov sawb thiab yob, lossis cov duab tsis zoo.
2. Ua ntej -Pass Tension Settings
Nyob rau hauv thawj qhov chaw, ib tug kuj loj pem hauv ntej nro yog tso cai vim hais tias cov khoom siv yog thicker thiab muaj zog. Lub nraub qaum, txawm li cas los xij, tsis tuaj yeem loj dhau: nws yuav tsum nyob twj ywm nrog qhov nro thov nyob rau hauv txoj kab nqes dej, txwv tsis pub inter- txheej slippage ntawm lub kauj tuaj yeem tshwm sim.
3. Kev sib npaug ntawm kev sib tw tom ntej
- Lub nraub qaum ntawm qhov kev hla tom ntej yog teem ntau dua qhov nro pem hauv ntej - ib qho xwm txheej uas ua rau lub sawb tsis tshua muaj kev tawg thiab txo qis zog dov.
- Qhov sib txawv ntawm qhov nro pem hauv ntej thiab nraub qaum yuav tsum tswj tau qis dua qhov kev txwv (hauv kev xyaum, ntawm qhov kev txiav txim ntawm 30 kN, thiab qis dua qhov tawm los- lub zog - raws li qhov nro ntawm cov sawb).
- Yog tias qhov nro rov qab loj dhau lawm, kev swb ntawm lub sawb thiab cov yob ua haujlwm yuav ua tau, ua rau degrading nto zoo thiab ntsuas ntsuas.
4. Ua ke nrog cov kab txuas txuas ntxiv
Qhov kawg - qhov kev sib tw nro yuav tsum tau ua ke nrog qhov kev sib tw tsis sib haum ntawm cov kab hauv qab txuas ntxiv txuas ntxiv. Qhov no ua kom du unwinding ntawm lub tiav kauj thiab tsis txhob nro mismatch uas yuav ua rau sawb kauj los yog nto puas thaum lub sij hawm annealing.
5. Cov cai tswj kev ua tau zoo
| Qhov xwm txheej | Kev nruj nruj |
|---|---|
| First pass (thick strip) | Loj pem hauv ntej nro; rov qab nro txwv los ntawm pickling kab |
| Intermediate passes | Rov qab nro> pem hauv ntej nro; Kev tswj qhov sib txawv (tsawg dua lossis sib npaug ~ 30 kN) |
| Rov qab nruj heev | Zam - ua rau yob slippage |
| xeem dhau | Match unwinding nro ntawm nruam annealing kab |
6. Cov lus xaus
Pem hauv ntej nraub qaum kev sib koom ua ke khiav los ntawm tag nrho cov txheej txheem txias-dov ntawm silicon steel. Cov nqi nro tsis tuaj yeem kho; lawv xav tau kev hloov pauv hloov pauv ua ke nrog cov sawb tuab, cov khoom muaj zog tawm los, cov txheej txheem pickling-line thiab downstream annealing-line tsis. Qhov sib txawv ntawm qhov sib txawv loj heev ua rau muaj kev pheej hmoo ntawm kev poob qis, thaum tsis txaus nro yuav ua rau tsis zoo strip flatness. Kev sib txuam ruaj khov yog qhov ua ntej rau qhov tsim nyog tuab qhov tseeb, qhov xwm txheej saum npoo thiab coil winding zoo ntawm silicon steel coils tiav.
