kwaye udlale indima ebalulekileyo ekubumbeni nasekubumbeni isinyithi kwiimveliso ezahlukeneyo. Phakathi kweentlobo ezahlukeneyo zemiqulu esetyenzisiweyo kwinkqubo, i-forged rolls, i-work rolls, i-back-up rolls kunye ne-back-up rolls ziyi-rolls eziphambili ezichaphazela ukusebenza kakuhle kunye nomgangatho we-hot rolling mill.

Ii-roller ezibunjiweyo zenziwe ngenkqubo yokubunjwa kunye nokunyanzeliswa kwesinyithi phantsi koxinzelelo oluphezulu, okubangelwa i-roller edibeneyo kunye neyomelele. Ezi ziqulunqo ziyaziwa ngamandla abo kunye nokukwazi ukumelana neemeko ezigqithiseleyo ze-hot rolling mill, ezenza zilungele imisebenzi enzima ebandakanyekayo kwinkqubo.

Imiqulu yokusebenza yolunye uhlobo olubalulekileyo lwe-roll esetyenziswa kwii-hot rolling mill kwaye inoxanduva lokubeka uxinzelelo kwisinyithi ukuze igqwese kwaye ibumbe ngokweenkcukacha ezifunekayo. Ezi ziqengqelezi zixhomekeke kwimithwalo ephezulu kunye namaqondo obushushu, zifuna ukuba zikwazi ukumelana nokunxiba kunye nokuzinza kwe-thermal ukuqinisekisa ukusebenza okuhambelanayo.

Ii-backup rolls zibonelela ngenkxaso kunye nokulinganisela kwimiqulu yomsebenzi, inceda ukugcina uzinzo kunye nokuchaneka kwenkqubo yokujikeleza. Le miqulu yenzelwe ukumelana namandla amakhulu asetyenziswa ngexesha lokuqengqeleka okushushu kweentsimbi, nto leyo ezenza zibe yinxalenye eyimfuneko ekuqinisekiseni umgangatho kunye nokuchaneka kwemveliso yokugqibela.

Njengoko igama libonisa, ii-backup rolls zibonelela ngenkxaso eyongezelelweyo kwi-work rolls kunye ne-backup rolls, inceda ekuphuculeni ukusebenza kakuhle kunye nokusebenza kwe-hot rolling mill. Le miqulu yenzelwe ukuphatha amandla asecaleni kunye nokuqinisekisa ulungelelwaniso olufanelekileyo lweminye imiqulu, ngaloo ndlela iphucula ukusebenza ngokubanzi kwenkqubo yokuqengqeleka.

Isishwankathelo, iintlobo ezahlukeneyo zemiqulu, kubandakanywa imiqulu edibeneyo, i-work rolls, i-back-up rolls, kunye ne-back-up rolls, ibaluleke kakhulu ekusebenzeni ngempumelelo kwe-hot rolling mill. Iimpawu zabo ezikhethekileyo kunye nobuchule banceda ukuphucula umgangatho jikelele, ukusebenza kakuhle kunye nokuchaneka kwenkqubo yokwenza isinyithi, okwenza kube yinto efunekayo kwishishini lokuvelisa.
