Covkub dov tshuab, raws li cov cuab yeej tseem ceeb hauv kev ua hlau, muaj cov txiaj ntsig tseem ceeb hauv qab no:
1. Kev ua tau zoo, txuag hluav taws xob thiab tus nqi zoo
Cov txheej txheem kub dov ua rau txo cov hlau deformation tsis kam los ntawm siab -kub dov, txo kev siv zog (los ntawm 30% -50% piv rau txias dov), thiab tib lub sijhawm, qhov loj txo qhov sib piv dov tuaj yeem txhim kho kev tsim khoom.
Txoj kev ua haujlwm tas mus li thiab kev siv tshuab ua haujlwm txuas ntxiv txo cov nqi zog. Piv txwv li, thaum siv loj ingot dov, ib qho kev ntim khoom tuaj yeem ncav cuag ntau tons.
2. Cov khoom ua tau zoo tshaj plaws
Nyob rau hauv ib puag ncig siab - qhov kub thiab txias, lub plasticity ntawm cov hlau txhim kho, thiab cov nplej tawg thiab cov dynamic recrystallization tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom thiab txo qhov tsis xws luag (xws li cov kab nrib pleb).
Los ntawm kev tswj dov thiab tswj cua txias (TMCP) thev naus laus zis, microstructure tuaj yeem tswj tau qhov tseeb, ua rau cov khoom muaj zog thiab tawv (xws li 20% -30% nce hauv yield zog).
3. Kev ua tau yooj yim thiab dav siv ntau yam
Nws yog qhov tsim nyog rau kev tsim cov khoom siv hlau ntau yam xws li ntu, tuav, thiab cov xov hlau, thiab los ntawm kev kho cov dov tsis tau, nws tuaj yeem ua tau raws li cov kev xav tau ntawm kev lag luam sib txawv (xws li kev tsim kho, nkoj tsim, thiab marine engineering).
Nws ua tiav cov txheej txheem txias dov thiab feem ntau ua haujlwm ua ntej- txheej txheem ua ntej txias dov, tsim cov txheej txheem "kub dov + txias dov" txheej txheem sib npaug kom sib npaug thiab qhov tseeb.
4. Kev txawj hloov tej zaum
Niaj hnub nimno kub dov tshuab, ua ke nrog cov tshuab ntse (xws li lub sijhawm tiag tiag- saib xyuas thiab ntsuas cov ntaub ntawv loj), tuaj yeem hloov kho qhov tsis zoo thiab ua tiav kev tsim khoom.
Cov thev naus laus zis txhim kho qhov zoo ntawm qhov chaw (xws li descaling thiab lubrication txhim kho) tau txo qhov sib txawv nrog cov khoom txias- dov.
Kev txwv
Qhov saum npoo tiav thiab qhov tseeb ntawm qhov kub- cov khoom dov tseem qis dua cov khoom txias- dov, tab sis los ntawm kev siv thev naus laus zis (xws li cov khoom siv hluav taws xob pov tseg thiab cov txheej txheem qis- carbon), cov kev txwv no maj mam dhau mus.
