Izigayo eziginqikayoidlala indima ebalulekile embonini yokukhiqiza, ukuguqula izinto zokusetshenziswa zibe izinhlobo ezahlukene zemikhiqizo yensimbi. Okubalulekile ekusebenzeni komshini wokugaya kukhonaimiqulu, ezibhekene nokubunjwa, ukunciphisa ukujiya nokudlulisela izakhiwo ezidingekayo ensimbi. Kule bhulogi, sizocubungula ukubaluleka kwama-roll rolls futhi sihlole ukuthi anikela kanjani ekuthuthukisweni kwenqubo yokukhiqiza.

Uma kuziwa ezigayweni eziginqikayo, ama-imiquluthatha isikhungo. Lezi zingxenye ezingamacylindrical zenzelwe ukumelana nokucindezela okukhulu, ukushisa namandla akhiqizwa ngesikhathi sokugingqika. Umsebenzi wabo oyinhloko uwukusebenzisa amandla ku-workpiece, kungakhathaliseki ukuthi insimbi, i-aluminium nanoma iyiphi enye insimbi, ngaleyo ndlela ibunjwe ngendlela oyifunayo. Amaroli enza kube lula ukushintshwa ukusuka kuma-ingots noma ama-slabs kuye komumo olawulekayo njengamashidi, amapuleti noma izintambo.

Irola, elinye igama elivame ukusetshenziswa ngokufanayo nelithi roll, liyingxenye ebalulekile yokugaya. Banomthwalo wemfanelo wokunciphisa ukujiya kwensimbi njengoba idlula emshinini wokugaya. Ama-roller afaka ingcindezi ensimbi, kancane kancane anciphisa ukushuba kwawo ngenkathi egcina ububanzi obuvumelanayo. Le nqubo iqinisekisa ukuvumelana komkhiqizo wokugcina, kungakhathaliseki ukuthi i-sheet metal esetshenziswa embonini yezimoto noma amakhoyili ekufakweni kukagesi.

Izinhlelo zokusebenza ezihlukahlukene ku-imboni yensimbibaye bavula indlela yokuthuthukiswa kwemiqulu ehlukahlukene efanele izinqubo ezihlukahlukene. Ngokuya ngezidingo ezithile zomshini wokugoqa, izinto ezibonakalayo, usayizi, ukwelashwa kokushisa kanye nokuqedwa kwendawo yama-roll kungahluka. Izinhlobo ezivame kakhulu zihlanganisaimiqulu yomsebenzi, imiqulu yokusekelayokanye nemiqulu ephakathi. Amaroli okusebenza athintana ngqo nensimbi, kuyilapho ama-back-up rolls ahlinzeka ngokusekela futhi avimbele ukukhubazeka komumo okubangelwa izimo zokucindezela okuphezulu. Ii-roller ephakathikusiza ukuhlukanisa ama-roller omsebenzi futhi ulungise ukungezwani kwezinto.

Ukukhetha amaroli ekhwalithi ephezulu kubalulekile ekugcineni ukusebenza kahle nokukhiqiza kwesigayo sakho. Amaroli anezinto ezibonakalayo ezinhle kakhulu, njengokuguga okuphezulu, ukumelana nokushisa nokukhathala, angakwazi ukumelana nezimo ezinzima zokugingqa usuku nosuku, anciphise isikhathi sokuphumula futhi andise impilo yesevisi. Ngaphezu kwalokho, ubukhulu obunembile, ukuphela kwendawo okunembayo nokuqondisa kahle kweroll kusiza ukuthuthukisa ikhwalithi yomkhiqizo, kunciphise udoti wezinto ezibonakalayo futhi kuthuthukise ukusebenza kahle kukonke.

Ngokuhamba kweminyaka, ukuthuthuka kwesayensi ye-metallurgical nobunjiniyela kuye kwashintsha ukwakheka nokukhiqizwa kwamaroli okugaya. Ama-alloys asungulayo, njengensimbi enesivinini esikhulu, insimbi yamathuluzi kanye namabanga ahlukahlukene e-carbide, athuthukisa ukusebenza nokuqina kwamaroli. Ukwengeza, inqubekelaphambili kubuchwepheshe bokukhiqiza amaroli afana nokusakazwa kwe-centrifugal kanye nezinqubo zokwelashwa kokushisa kudlale indima ebalulekile ekuthuthukiseni impilo nokusebenza kwamaroli okugaya.

Ngamafuphi, ama-rolling mill rolls asebenza njengamaqhawe angaziwa, asiza ukuguqulwa kwezinsimbi zibe imikhiqizo ebalulekile enika amandla izimboni eziningi. Ukusuka ekubumbeni nasekunciphiseni ukujiya kuya ekudluliseleni izici ezifiselekayo ensimbi, amaroli ayingxenye ebalulekile yenqubo yokugoqa. Ngokuqonda ukubaluleka kwamaroli kanye nokwamukela intuthuko yezobuchwepheshe, abakhiqizi bangakwazi ukuthuthukisa imisebenzi yabo yokugaya, bathole ukukhiqiza okuphezulu, futhi balethe imikhiqizo yekhwalithi ukuze ihlangabezane nezidingo ezikhulayo zomkhakha wanamuhla.
