Rolls yog cov khoom tseem ceeb hauv dov mills thiab siv los siv lub zog thaum lub sij hawm dov steel. Cov ntaub ntawv yob muaj xws li cam khwb cia hlau yob, cam khwb cia hlau yob, forged yob, thiab carbide yob siv nyob rau hauv ib co profile mills. Thaum lub sijhawm ua haujlwm, cov yob raug cuam tshuam los ntawm kev thauj khoom hnyav thiab hloov pauv kub, uas tuaj yeem ua rau hnav thiab deformation. Yog li ntawd, kev sib tsoo tsis tu ncua nrog lub siab - zooyob sib tsoo logyog tsim nyog.
Hauv kev lag luam steel, yob sib tsoo feem ntau muab faib ua kub dov thiab txias dov. Cov rolls tseem ceeb uas yuav tsum tau kho muaj xws li:
◆ Ua haujlwm yob
◆ Cov yob nruab nrab
◆ Thaub qab yob
Ib qho kev sib tsoo lub log yog tsim los muab kev sib tsoo ruaj khov, kev ua haujlwm siab, thiab zoo nto tiav. Raws li kev sib tsoo sib txawv, lub log tuaj yeem ua nrog alumina, silicon carbide, lossis ceramic abrasives.
Cov lus qhia tshwj xeeb ntawm lub log sib tsoo muaj xws li:
Grain loj: 24 # - 1000 #
Hardness: C-N
Txoj kab uas hla: 450mm-1100mm
Thickness: 35mm-152mm
Cov duab ntawm yob sib tsoo log khoom muaj xws li:
Hom 1: Parallel sib tsoo log
Hom 5: Ib leeg -sab concave sib tsoo log
Hom 7: Ob chav -sided concave sib tsoo log
Hom 21: Ob chav -sided tapered concave sib tsoo log
Feem ntau cov ntawv yob sib tsoo log siv ntub dej sib tsoo nrog 2-3% dej-soluble emulsion, uas yuav pab txo kom sov thiab txhim kho kev sib tsoo zoo. Xaiv txoj cai yob sib tsoo lub log tuaj yeem txhim kho yob qhov tseeb, txuas ntxiv yob lub neej, thiab ua kom cov khoom ua tau zoo hauv cov hlau mills.
