Rolls yog ib qho tseem ceeb ntawm cov txheej txheem kub dov zeb, ua lub luag haujlwm tseem ceeb hauv kev tsim thiab tsim cov hlau rau hauv ntau yam khoom. Ntawm cov sib txawv ntawm cov yob siv nyob rau hauv cov txheej txheem no, forged yob, ua hauj lwm yob, thaub qab yob, thiab kev txhawb nqa yob yog cov tseem ceeb uas ua rau kom ua tau zoo thiab zoo ntawm cov kub dov zeb.

Forged rolls yog tsim los ntawm cov txheej txheem ntawm shaping thiab compressing hlau nyob rau hauv siab siab, uas ua rau ib tug tuab thiab check yob. Cov yob no paub txog lawv lub zog thiab muaj peev xwm tiv taus cov xwm txheej huab cua kub dov mills, ua rau lawv zoo tagnrho rau cov kev xav tau kev koom tes hauv cov txheej txheem.

Rolls ua hauj lwm yog lwm yam tseem ceeb ntawm yob siv nyob rau hauv kub dov mills, lub luag hauj lwm rau kev thov siab rau cov hlau kom deform thiab zoo raws li qhov xav tau specifications. Cov yob no raug rau siab loads thiab kub, xav kom lawv muaj zoo heev hnav tsis kam thiab thermal stability kom ntseeg tau zoo ib yam.

Backup rolls muab kev txhawb nqa thiab sib npaug rau kev ua haujlwm yob, pab tswj kev ruaj ntseg thiab precision ntawm cov txheej txheem dov. Cov yob no yog tsim los tiv thaiv lub zog loj heev thaum lub sij hawm kub dov ntawm cov hlau, ua rau lawv yog ib qho tseem ceeb ntawm kev ua kom ntseeg tau qhov zoo thiab qhov tseeb ntawm cov khoom kawg.

Kev them nyiaj yug rolls, raws li lub npe qhia, muab kev txhawb nqa ntxiv rau kev ua haujlwm thiab cov ntaub ntawv thaub qab, pab txhawb rau tag nrho cov txiaj ntsig thiab kev ua tau zoo ntawm cov kub dov zeb. Cov rolls no yog tsim los tswj lub zog ntawm sab nraud thiab xyuas kom muaj kev sib raug zoo ntawm lwm cov yob, yog li txhim kho tag nrho cov kev ua tau zoo ntawm cov txheej txheem dov.

Hauv kev xaus, ntau hom yob, suav nrog forged rolls, ua haujlwm yob, thaub qab yob, thiab kev txhawb nqa yob, yog ib qho tseem ceeb rau kev ua haujlwm zoo ntawm cov rolling mills. Lawv cov yam ntxwv tshwj xeeb thiab kev ua haujlwm pab txhawb rau tag nrho cov khoom zoo, kev ua tau zoo, thiab qhov tseeb ntawm cov txheej txheem hlau shaping, ua rau lawv cov khoom tseem ceeb hauv kev tsim khoom.
