Ezozingqusho ezishushu,inkxaso rollersdlala indima ebalulekileyo kuyo yonke le nkqubo. Le miqulu, eyaziwa ngokubaimiqulu yomsebenzi or isantya esiphezulu sentsimbis, ukunika inkxaso kunye nozinzo kwiimiqulu eshushungexesha lenkqubo yokuqengqeleka. Zibalulekile ekuqinisekiseni umgangatho kunye nokusebenza kakuhle kwemisebenzi yokuqengqeleka kwesinyithi.

I-Hot rolling yinkqubo apho i-ingot yensimbi okanye i-slab ifudunyezwa kwiqondo lokushisa eliphezulu kwaye emva koko idluliselwe kuluhlu lwee-roller ukunciphisa ubukhulu bayo kwaye ibumbe ngendlela oyifunayo. Ii-roller ezifudumalayo, ezihambelana ngokuthe ngqo nesinyithi, ziphantsi koxinzelelo olukhulu kunye nobushushu ngexesha lenkqubo. Apha kulapho iiroli zenkxaso zingena khona.

I-roller yokuxhasa ifumaneka emva kwe-roller yokushisa kwaye isebenza njengenkqubo yenkxaso yokukhusela i-roller yokushisa ekugobeni okanye ukuguqulwa phantsi koxinzelelo olunzima. Basebenza ngokubambisana kunye nemiqulu eshushu ukuqinisekisa ukuthotywa okulinganayo kunye nokuhambelanayo kubukhulu bentsimbi. Ngaphandle kwee-roller zenkxaso, i-heat rollers iya kunxiba ngokulula, okukhokelela kwimveliso ephantsi yokuphela.

Ukongezelela ekuboneleleni ngenkxaso, i-roller yenkxaso inceda ukugcina imilo kunye nokulungelelaniswa kwe-heat roller, eyona nto ibalulekileyo ekufezekiseni umkhiqizo ofunekayo wokuphela. Ngokuqhelekileyo zenziwe ngentsimbi yesantya esiphezulu, into eyaziwayo ngokuhlala kwayo kunye nokuchasana namaqondo okushisa aphezulu, okwenza kube yinto efanelekileyo yeemeko ezinzima zemill rolling eshushu.

Kubalulekile ukuba i-hot rolling Mills ihlole rhoqo kwaye igcine iiroli zabo zenkxaso ukuqinisekisa ukusebenza kakuhle. Nawuphi na umonakalo okanye ukugqoka kwii-roller ezigcinayo kunokuba nefuthe elibalulekileyo kumgangatho kunye nokusebenza kakuhle kwenkqubo yokuqengqeleka. Ngokwenza utyalo-mali kwii-backup rolls ezikumgangatho ophezulu kunye nokuphumeza iindlela ezifanelekileyo zokulondoloza, ii-hot rolling Mills zinokuphucula ukuthembeka kunye nemveliso yemisebenzi yazo.

Ngamafutshane, i-backup roller yinxalenye ebalulekileyo ye-hot rolling mill kwaye idlala indima ebalulekileyo ekuxhaseni nasekugcineni ukusebenza kwe-hot rolling mill. Ukuqonda ukubaluleka kwabo kunye nokutyalomali ekugcinweni kwabo kubalulekile ekufezekiseni umgangatho ophezulu kunye neziphumo ezihambelanayo kwinkqubo yokuqengqeleka kwesinyithi.
