Sesebelisoa sa Koporo sa Koporo se Phahameng sa Ts'ebetso e Phahameng

Taba ea pele, melemo ea lintho tse bonahalang ea boronse ea loto

Boronse ea loto e na le thepa e ntle ea ho itlotsa. Likaroloana tsa loto li etsa filimi ea ho tlotsa nakong ea khohlano, 'me coefficient ea khohlano e ka ba tlase ho 0.01-0.05, e leng se fokotsang haholo ho tsofala ha likarolo tse tsamaeang.

Ha ho tluoa tabeng ea bokhoni ba ho jara mojaro, boronse ea loto e sebetsa hantle. Khatello e lumelletsoeng e itseng e ka fihla ho feta 25MPa, e leng se fihlelang ka botlalo litlhoko tsa ts'ebeliso tlas'a maemo a mojaro o boima.

Boronse ea loto e boetse e na le khanyetso e ntle ea mafome. E na le khanyetso e ntle ea mafome metsing a leoatle, metsing a hloekileng le libakeng tse ling ho netefatsa bophelo ba tšebeletso ea thepa.

2. Litekanyetso tsa tekheniki tsa boronse ea loto

Metswako e tloaelehileng ea lik'hemik'hale tsa boronse ea loto e kenyelletsa: dikahare tsa koporo tsa 60-80%, dikahare tsa thini tsa 5-10%, dikahare tsa loto tsa 5-25%. Karolelano ena e nepahetseng ya sebopeho e netefatsa botsitso le botsitso ba thepa ya thepa.

Ha ho tluoa tabeng ea thepa ea 'mele, boima ba boronse ea loto ke 8.5-9.0g/cm³, ntlha ea ho qhibiliha ke 850-950℃, 'me coefficient ea katoloso ea mocheso ke 18.0×10⁻⁶/℃. Liparamente tsena li khetholla botsitso le ts'epo ea eona libakeng tse nang le mocheso o phahameng.

Litekanyetso tsa tshebetso ya mechini di bontsha hore matla a ho kganna a boronse ya loto a feta 300MPa mme ho lelefala ho feta 10%, e leng se netefatsang polokeho le ho tshwarella ha thepa nakong ya tshebediso.

3. Mehlala ea ts'ebeliso ea boronse ea loto

Lefapheng la mechini ea merafo, boronse ea loto e sebelisoa haholo tlhahisong ea li-bearing tsa ball mill, crusher bushing le likarolo tse ling tsa bohlokoa. Ho hanyetsa ho tsofala ha eona hantle le thepa ea eona ea ho itlotsa e netefatsa ts'ebetso e tsitsitseng ea nako e telele ea lisebelisoa.

Lisebelisoang tsa tšepe, boronse ea loto e sebelisoa ho etsa likarolo tsa bohlokoa tse kang li-rolling mill bearing le li-coasting machine bearing tse tsoelang pele. Bokhoni ba eona bo phahameng ba ho jara mojaro le ts'ebetso ea ho thibela mokhathala li fana ka tiisetso e tšepahalang bakeng sa ts'ebetso e sireletsehileng ea lisebelisoa.

Lefapheng la mechini ea kaho, boronse ea loto e atisa ho sebelisoa ho etsa likarolo tsa bohlokoa tse kang li-excavator bearing le li-bulldozer bushings. Ho hanyetsa ha eona tšusumetso le ho hanyetsa ho tsofala ho fihlela litlhoko tse tiileng tsa mechini ea kaho ka botlalo.
