Kumashishini oomatshini,imiqulu yokugcina, imiqulu yomsebenzi kunyeimiqulu yentsimbi enesantya esiphezulu dlala indima ebalulekileyo ekuqinisekiseni ukusebenza ngokutyibilikayo nangokufanelekileyo. La macandelo abaluleke kakhulu kwinkqubo yokuvelisa kumashishini ahlukeneyo kuquka intsimbi, iimoto kunye nemveliso. Ukuqonda ukubaluleka kwezi rollers kubalulekile kumashishini ajonge ukwandisa iinkqubo zawo zemveliso kunye nokugcina imveliso ekumgangatho ophezulu.

Ii-backup rolls ziyinxalenye ebalulekileyo ye-rolling mill, inika inkxaso kunye nokuzinza kwii-rolling rolls ngexesha lenkqubo. Ngokuqhelekileyo zenziwe ngentsimbi ephezulu kwaye zenzelwe ukujamelana noxinzelelo oluphezulu kunye nobushushu. I-backup rolls inceda ekuqinisekiseni ukusasazeka koxinzelelo kwimiqulu yomsebenzi, ukuthintela ukungalingani kwezinto eziphathekayo kunye neziphene eziphezulu kwimveliso yokugqibela.

Imiqulu yomsebenzi zizixhobo eziphambili ezisetyenziswa kwinkqubo yokuqengqeleka kwaye zinoxanduva lokubumba kunye nokunciphisa ubukhulu bezinto ezicutshungulwayo. Ezi rollers ziphantsi koxinzelelo olugqithisileyo kunye nokunxiba, okwenza ukuba zibe yinxalenye ebalulekileyo kwimigca yemveliso. Imiqulu yomgangatho ophezulu womsebenzi ibaluleke kakhulu ekufezekiseni imilinganiselo yemveliso echanekileyo kunye engaguqukiyo, ukugqiba umphezulu kunye neempawu eziphathekayo.

Iiroli ze-HSS (iSpeed ​​​​Speed ​​​​Steel) ziyaziwa ngokuxhathisa kwazo okugqwesileyo, ukuhanjiswa kwe-thermal kunye nobunzima obuphezulu. Le miqulu idla ngokusetyenziswa kwizicelo zokuqengqeleka ezishushu kwaye ziphantsi kobushushu obugqithisileyo kunye nemithwalo enzima. Imiqulu yensimbi enesantya esiphezulu yenzelwe ukuxhathisa ezi meko zinzima, ibonelela ngokusebenza okuphezulu kunye nobomi benkonzo obude kunezinto eziqhelekileyo zomqulu.

Ukugcinwa ngokufanelekileyo kunye nokutshintshwa rhoqo kwee-backup rolls, i-work rolls kunye ne-high-speed rolls zensimbi ziyimfuneko ukuze kuqinisekiswe ukusebenza ngokufanelekileyo nokuthembekileyo koomatshini boshishino. Ukuhlolwa rhoqo kunye nokulungiswa kunceda ukufumanisa ukuguga kunye nomonakalo kwangethuba, ukuthintela ukwehla kweendleko kunye nokulibaziseka kwemveliso. Ukwenza utyalo-mali kwimiqulu ekumgangatho ophezulu kunye nokwamkela ezona ndlela zilungileyo zokugcinwa koluhlu kunokuchaphazela kakhulu ukusebenza kunye nenzuzo yomsebenzi wakho wokuvelisa.

Isishwankathelo, i-backup rolls, i-work rolls kunye ne-high-speed roll rolls zizinto eziyimfuneko kumatshini woshishino kwaye zidlala indima ephambili kwimveliso yezinto eziphezulu. Ukuqonda ukubaluleka kolu luhlu kunye nokuphunyezwa kwezicwangciso eziliqili zolondolozo kubalulekile kumashishini afuna ukufezekisa imveliso egqwesileyo kunye nomgangatho wemveliso ongaguqukiyo.
