Nyob hauv lub ntiaj teb ntawm steel ntau lawm, dov mills yog tus caj qaum ntawm kev lag luam. Cov tshuab siab tshaj plaws hloov pauv ntawm cov hlau ua cov ntawv cim, daim hlau thiab ntau yam khoom ntawm cov ntawv ua tib zoo tsim cov menyuam. Ntawm cov so no,Backup RollsthiabUa Haujlwm RollsUa si lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ua haujlwm tau zoo thiab zoo ntawm cov txheej txheem. Tshwj xeeb, kub yob tau ua tshais kev ua si, kev txhawb nqa cov txheej txheem hlau. Cov blog no lub hom phiaj los txiav lub teeb rau qhov tseem ceeb ntawm cov ntim thiab lawv qhov cuam tshuam rau kev lag luam.

1. Txhawb nqa cov menyuam:
Backup Rolls yog ib qho tseem ceeb ntawm ib npib uas lawv muab kev txhawb nqa thiab ruaj khov rau cov haujlwm qaws. Lawv raug rau lub zog loj thiab kub kub tsim thaum lub sijhawm dov. Kev ntseeg tau thiab ruaj khov ntawm cov ntaub pua no cuam tshuam qhov zoo thiab muaj txiaj ntsig ntawm cov khoom kawg. Siv cov ntaub ntawv zoo thiab cov txheej txheem kev tsim khoom ua kom ceev ceev ceev kom dov cov mills khiav zoo, txo qis kev ua haujlwm thiab nce tag nrho cov khoom lag luam.

2. Ua haujlwm yob:
Txoj kev ua haujlwm qaws yog lub tseem ceeb yob lub luag haujlwm rau kev sib sau thiab ua kom haum cov hlau. Lawv muaj kev sib chwv nrog cov khoom siv tau yob thiab raug rau kev ntxhov siab zoo heev, suav nrog dabtsi yog khoov thiab deformation. Yog li ntawd, kev ua haujlwm rolls yuav tsum muaj Hardness Zoo heev, kev nruj thiab kub tsis kam mus tiv xwm txheej ntawm Rolling Mill.

3. Cov yob kub kub:
Qhov kub yob yog qhov kev hloov tshiab tsis ntev los no uas tau hloov kho steel ntau lawm. Kev lig kev cai, cov ntawv nplaum steel yog dov thaum kub thiab txias ua ntej ua ntej. Txawm li cas los xij, cov chais kub tsis tas yuav tsum txias, uas txuag tau ntau lub sijhawm thiab lub zog. Los ntawm kev tswj kom muaj qhov kub siab thaum lub sijhawm dov, cov qaws kub pab tau ntau cov khoom siv thiab txhim kho cov khoom siv. Qhov kev hloov tshiab no txo ​​cov nqi ua haujlwm, nce kev ua tau zoo, thiab tsim cov khoom lag luam zoo steel.

Backup Rolls, ua haujlwm rolls thiab kub yob yog qhov tseem ceeb ntawm niaj hnub yob mills. Lawv xyuas kom meej ntawm kev ua tshuab thiab pab kom ua kom muaj kev ua tau zoo thiab ua tau zoo ntawm cov hlau. Raws li thev naus laus zis txuas ntxiv mus ua ntej, nws yog qhov tseem ceeb rau cov tuam ntxhab los nqis peev hauv xeev-ntawm-cov-kos duab yob kom nyob twj ywm sib tw hauv kev lag luam. Los ntawm kev ua li ntawd, cov khoom lag luam hlau tuaj yeem ua ntau ntau yam, txo qis qis, thiab ua tau raws li kev cog qoob loo ntawm kev lag luam hauv ntiaj teb
