Ekukhiqizeni insimbi eshisayo, ikhwalithi yemiqulu esetshenziswe kule nqubo ingaba nomthelela omkhulu kumkhiqizo wokugcina. Ukukhetha okudumile kulawa ma-roller kukhonahigh chromium iron rollers, owaziwa nangokuthi ama-cast iron rollers. Lawa ma-roll aziwa ngokuqina kwawo, ukumelana nokushisa kanye nokusebenza okuphezulu kukonke phakathi nenqubo yokuginqika okushisayo.

I-chromium iron rolls ephezuluzenziwe ngensimbi ekhonjiwe enokuqukethwe okuphezulu kwe-chromium. I-alloy inokugqoka okuhle kakhulu nokumelana nokushisa, okuyenza ibe yimpahla efanelekile yezigayo ezishisayo. Okuqukethwe kwe-chromium ephezulu kunikeza amaroli ubulukhuni obuphezulu, okusiza ngokuqhubekayo ukunweba impilo yamaroli futhi kuwenze akwazi ukumelana nokucindezela okukhulu nokushisa okuhilelekile kunqubo yokugingqika.

Enye yezinzuzo eziyinhloko zokusebenzisahigh-chromium iron rolls kuma-hot rolling Mills yikhono lawo lokugcina isimo sawo kanye nekhwalithi ephezulu ngokuhamba kwesikhathi. Lokhu kubalulekile ukuze kuqinisekiswe ukukhiqizwa okungaguquki futhi okusezingeni eliphezulu kwemikhiqizo yensimbi. Ukumelana nokushisa kwalawa ma-roller nakho kuvumela ukusebenza kahle, okuqhubekayo ngaphandle kwesidingo sokushintshwa noma ukulungiswa njalo.

Ngaphezu kokuqina, amaroli ensimbi ane-chromium ephezulu anikezela ngokushelela, okufana nokuqedwa kwendawo, okubalulekile ekukhiqizeni imikhiqizo yensimbi yekhwalithi ephezulu. Lokhu kuqedwa kwendawo kusiza ukuvimbela noma yiziphi izisihla noma ukungapheleli kunsimbi egoqiwe, okuholela kumkhiqizo wokugcina wekhwalithi.

Ukwengeza, ngokuhamba kwesikhathi, amaroli ensimbi e-chromium aphezulu anikeza inzuzo yokuthi angabizi kakhulu ngenxa yempilo yabo ende yesevisi kanye nezidingo zokulondolozwa okuncane. Lokhu kubenza babe utshalomali oluhlakaniphile lwabenzi bensimbi abafuna ukuthuthukisa inqubo yabo yokugoqa okushisayo kanye nekhwalithi yomkhiqizo.

Kafushane, amaroli ensimbi e-chromium aphezulu ayinketho yokuqala yamaroli ensimbi ashisayo ngenxa yokuqina kwawo okuhle kakhulu, ukumelana nokushisa nokusebenza kukonke. Ngokusebenzisa lezi zigayo ezigayweni ezishisayo, abenzi bensimbi bangaqinisekisa ukukhiqizwa okuthembekile nokusezingeni eliphezulu kuyilapho benciphisa izindleko zokulungisa nokushintsha. Amakhoyili ensimbi e-chromium aphezulu anikeza izinzuzo eziningi futhi ayigugu embonini yensimbi.
