Raws li cov tseem ceeb tivthaiv nyob rau hauv lub rolling txheej txheem, cov roj hmab siv hlau tau faib rau ntau txoj kev, thiab txhua hom muaj cov ntawv thov tshwj xeeb thiab cov txiaj ntsig.
Los ntawm cov kev pom ntawm cov khoom, cov xaim hluav taws xob tuaj yeem faib ua cov roj carbon steel, thiab lwm yam. Cov ntaub pua dav dav dav hlau, thiab siv tshuab hluav taws xob ntau, thiab haum rau thaum ntxov dov thev naus laus zis. Alloy Steel chais tau txhim kho qhov nyuaj thiab hnav tsis kam los ntawm kev ntxiv cov khoom siv chromium, thiab feem ntau siv nyob rau hauv cov kev xav tau ntawm kev dov cov khoom thiab ua tau zoo. High-ceev steel rollers yog qhov haum rau high-ceev siv cov kab ntau lawm, thiab lawv cov kev coj tawm tsam kom muaj kev ruaj khov thiab khoom lag luam zoo.
Ntxiv rau cov ntaub ntawv, cov xaim hluav taws xob tuaj yeem ua rau cais raws cov duab thiab daim ntawv thov. Hloov cov tog yog hom feem ntau, siv rau kev ua hlau ua ke nrog cov siab tiaj tiaj thiab tuab. Cov duab dhos ua si, elliptical thiab lwm yam tsis-round rollers yog qhov haum rau kev ua cov ntawv hlau ntawm cov duab tshwj xeeb. Ib qho ntxiv, muaj vibrating chais, uas nce deformation tus nqi ntawm cov hlau nplaum los ntawm kev co los ntawm kev co kom zoo nkauj lossis zom mov thiab khawb thaum ua.
Hauv kev siv cov kab ntau lawm, cov hlua hluav taws xob yob thiab silicon carmide cov ntaub nyias nyias vim lawv lub siab hnav tsis kam, cov khoom tsis sib thooj. Txawm li cas los xij, lawv cov nqi yog qhov siab.
Kev xaiv ntawm kev xaiv hlau yob yuav tsum tau ua raws cov txheej txheem yob tshwj xeeb, suav nrog yob loj, dov nrawm, dov ntau yam thiab lwm yam. Qhov kev xaiv yog tsis tuaj yeem tsuas yog tias cov yob muaj kev ua tau zoo heev, tab sis kuj tseem muaj kev cuam tshuam zoo thiab tsim khoom ntawm cov khoom siv yob.
