Li-tubes tsa hlobo ea koporoke karolo ea bohlokoa ea indasteri ea tlhahiso, haholo-holo tlhahiso ea lihlahisoa tsa tšepe tsa boleng bo phahameng. Ka conductivity ea eona e ntle ea mocheso le nako e telele,li-tubes tsa hlobo tsa koporoli sebelisoa haholo ka mefuta e fapaneng ya dikopo, ho akarelletsa le tlhahiso ea lisekoere le100X100 li-tubes tsa hlobo.

Li-tubes tsa hlobo tse lisekoere li etselitsoe ho etsa lihlahisoa tsa tšepe tse lisekoere, tse atisang ho sebelisoa ho aha le ho khabisa. Moqapi o ikhethang oa tube ea square mold e etsa hore tšepe e sebetse hantle le e nepahetseng, e leng se etsang hore ho be le lihlahisoa tse ntle feela empa hape li utloahala hantle. Tšebeliso ea koporo ka li-tubes tsa square mold e tiisa hore esita le kabo ea mocheso, e leng bohlokoa ho finyella lihlahisoa tsa tšepe tse lisekoere tse tsitsitseng le tsa boleng bo phahameng.

Ka lehlakoreng le leng, 100X100 mold tube e loketse ho hlahisa lihlahisoa tsa tšepe tsa boholo bo itseng. Hangata li-tubes tsena tsa hlobo li sebelisoa ho boenjiniere bo nepahetseng le tlhahiso moo ho nepahala le ho nepahala ho leng bohlokoa haholo. Tšebeliso ea koporo ka har'a tube ea hlobo ea 100X100 e tiisa hore tšepe e futhumatsa le ho pholile ka ho lekana, e hlahisa lihlahisoa tse kopanang le mamello e tiileng.

Ntle le ho fana ka ts'ehetso, li-roller tsa tšehetso li thusa ho boloka sebōpeho le ho lumellana ha mocheso oa mocheso, e leng oa bohlokoa ho finyella sehlahisoa se lakatsehang sa ho qetela. Ka tloaelo li entsoe ka tšepe ea lebelo le phahameng, thepa e tsejoang ka ho tšoarella ha eona le ho hanyetsa mocheso o phahameng, e leng se etsang hore e be se loketseng maemo a thata a li-mill rolling tse chesang.

Ho bohlokoa hore li-hot rolling Mills li hlahlobe khafetsa le ho boloka meqolo ea tsona ea tšehetso ho netefatsa ts'ebetso e nepahetseng. Tšenyo leha e le efe kapa ho apara li-rollers tsa "backup" ho ka ba le tšusumetso e kholo ho boleng le katleho ea mokhoa oa ho roala. Ka ho tsetela ho li-backup rolls tsa boleng bo holimo le ho kenya ts'ebetsong mekhoa e nepahetseng ea tlhokomelo, liloala tse chesang li ka ntlafatsa ts'epo le tlhahiso ea ts'ebetso ea tsona.

Ka bokhuts'oane, "backup roller" ke karolo ea bohlokoa ea leloala le chesang 'me e bapala karolo ea bohlokoa ho ts'ehetsa le ho boloka ts'ebetso ea leloala le chesang. Ho utloisisa bohlokoa ba bona le ho tsetela tlhokomelong ea bona ke habohlokoa ho finyella boleng ba boleng bo phahameng le liphello tse tsitsitseng ts'ebetsong ea ho roala tšepe.
