Forged rolls yog tsim los ntawm cov txheej txheem uas cov duab thiab compresses hlau nyob rau hauv kev kub siab, uas ua rau cov khoom ntom ntom thiab ruaj khov. Cov txheej txheem forging no ua rau kom lub zog thiab kev ncaj ncees ntawm cov yob, cia lawv tiv taus cov khoom hnyav thiab kev ua haujlwm hnyav.

Cov yob ua haujlwm yog cov khoom tseem ceeb hauv cov hlau dov mills thiab siv los deform thiab zoo li cov hlau phaj thiab tuav. Cov rolls no raug rau siab heev thiab kev sib txhuam thaum lub sij hawm dov txheej txheem, yog li nws yog ib qho tseem ceeb uas lawv yuav tsum tau forged los ntawm cov ntaub ntawv zoo los xyuas kom meej lub neej ntev thiab kev ua tau zoo.

Backup rolls muab kev txhawb nqa thiab kev ruaj ntseg rau kev ua haujlwm yob, pab tswj cov duab thiab tuab ntawm cov hlau ua tiav. Cov yob no kuj raug rau cov khoom hnyav thiab xav tau lub zog thiab elasticity uas forged yob tuaj yeem muab tau.

Backup rollers, ntawm qhov tod tes, yog siv ntau yam kev lag luam siv los muab kev txhawb nqa ntxiv thiab kev taw qhia rau cov khoom ua tiav. Txawm hais tias nyob rau hauv daim ntawv tsim khoom lossis kev ua cov yas, kev txhawb nqa cov menyuam ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm kom zoo thiab ua haujlwm zoo ntawm cov tshuab.

Kev siv forged yob hauv cov ntawv thov no yog qhov tseem ceeb rau kev tswj xyuas kev ncaj ncees thiab kev ua haujlwm ntawm cov txheej txheem kev lag luam. Lawv cov kav ntev thiab tsis kam hnav thiab tsim kua muag ua rau lawv muaj txiaj ntsig kev nqis peev rau cov tuam txhab nrhiav kev txhim kho lawv cov kev tsim khoom.
