20CrNiMo Alloy Pipe ea tšepe e se nang seamless

20CrNiMo qalong e ne e le nomoro ea tšepe ea 8620 ho litekanyetso tsa Amerika tsa AISI le SAE.Ts'ebetso ea ho thatafala e tšoana le ea tšepe ea 20CrNi.Le hoja litaba tsa Ni ka tšepe e le halofo ea tšepe ea 20CrNi, ka lebaka la ho eketsoa ha karolo e nyenyane ea Mo element, karolo e ka holimo ea austenite isothermal phetolo curve e fallela ka ho le letona;'me ka lebaka la keketseho e nepahetseng ea Mn content, ho thatafala ha tšepe ena e ntse e le ntle haholo, le matla E boetse e phahame ho feta 20CrNi tšepe, hape e ka nka sebaka sa tšepe ea 12CrNi3 ho etsa likarolo tsa carburized le likarolo tsa cyanide tse hlokang ts'ebetso e phahameng ea mantlha.20CrNiMo e ka mamella mocheso o itseng ntle le thepa e ntle e felletseng hobane e na le molybdenum.

Sebaka sa Kopo

1. Lefapheng la tlhahiso, hangata e sebelisoa ho etsa likarolo tse tlas'a moroalo o phahameng, khatello e phahameng ea maikutlo, le ho apara ka holimo, joalo ka li-gear, shafts, bearings, joalo-joalo. bophelo bo bolelele ba tšebeletso libakeng tse thata tsa mosebetsi.Ho phaella moo, e boetse e na le ho hanyetsa mokhathala o babatsehang le ho hanyetsa kutu, e ka thibelang ka katleho ho senyeha ha tikoloho ea ka ntle le ho netefatsa ts'ebetso e tsitsitseng ea lisebelisoa.

2. Sebakeng sa kaho, tšepe ena e sebelisoa haholo ha ho hahoa mehaho e meholo e kang marokho le mehaho e phahameng ka lebaka la matla a eona a phahameng le ductility e ntle.Mehahong ena, ba ka mamella khatello e kholo le tsitsipano, ho netefatsa polokeho le botsitso ba mohaho.

3. Ho phaella moo, ka ntlafatso ea tlhokomeliso ea tikoloho, likopo lefapheng la ts'ireletso ea tikoloho li ntse li eketseha le ho feta.Ka mohlala, likoloing tse ncha tsa matla, li ka sebelisoa ho etsa likarolo tsa bohlokoa tse kang li-motors le li-reducers, tse tlatsetsang maetong a tala.E boetse e phetha karolo ea bohlokoa ho thepa ea ts'ireletso ea tikoloho e kang ho hloekisa likhoerekhoere le phekolo ea khase ea litšila, ho fana ka tšehetso e matla bakeng sa ho ntlafatsa boleng ba tikoloho.

Libaka tsa Kopo

1. Likarolo tsa bohlokoa tsa meralo, joalo ka lisebelisoa tsa ho theola sefofane, litanka le likarolo tsa koloi e hlometseng.

2. Li-fasteners tse matla le li-connectors.

3. Likarolo tse phahameng tsa thepa le li-bearings.

Tlhaloso ea Phekolo ea Mocheso

Ho felisa 850ºC, serame sa oli;Mohatla 200ºC, ho pholisa moea.

Boemo ba Phano

Ho fana ka phekolo ea mocheso (ho tloaeleha, ho fokotsa mocheso kapa mocheso o phahameng oa mocheso) kapa ho se na boemo ba phekolo ea mocheso, boemo ba ho pepa bo tla bontšoa tumellanong.
