China OEM tloaelo ductile tšepe lahleheloa ke bokalihlahisoa tsa lichelete tsa licheleteka mochini oa CNC, kalafo ea mocheso le lits'ebeletso tsa kalafo ea holim'a metsi.
Hangata e lahleloa ka ho lahla lichelete, ho lahla lehlabathe le letala leho lahla hlobo, Litšepe tsa tšepe tsa ductile li fana ka phetoho ea moralo le ho fokotsa litšenyehelo tsa tlhahiso ha li bapisoa le masela a cheselitsoeng le ho forging. Lisebelisoa tsa tšepe tsa ductile li na le litšoaneleho tse ngata, leha ho le joalo, hase kamehla mekhoa e meng e nang le litšenyehelo tse ngata ho feta li-alloys tse ling tsa ferrous. Ho feta moo, li-iron tsa ductile li sebelisoa haholo liindastering tse ngata tsa tlhahiso, ho kenyeletsoa temo, likoloi, li-hydaulics, literene tsa terene, literaka tsa khoebo le liindasteri tsa sefofane.
Tšepe ea cast, haholo-holo e kenyelletsang tšepe e bohlooho le ductile (nodular) tšepe e entsoeng ka tšepe e sebelisoa haholo bakeng sa ho lahla lehlabathe, ho lahla khetla, ho lahla lehlabathe kapa ho lahleheloa ke foam. Leha ho le joalo, bakeng sa maemo a itseng a khethehileng, thets'ebetso ea ho lahla chelete e lahlehilenge boetse e sebelisoa ka lebaka la boemo ba bona bo botle le ho nepahala ho phahameng. Ho RMC, re boetse re na le bokhoni ba tha ba ho lahla tšepe e bohlooho le ductile ka nepo e lahlehileng ea boka ba matsete ka ho sebelisa silika le khalase ea metsi bakeng sa moaho oa likhetla. Lisebelisoa tsa tšepe ke li-alloys tsa ferrous tse nang le lik'habone tse fetang 2%. Le hoja litšepe tse entsoeng ka tšepe li ka ba le peresente ea carbon pakeng tsa 2 le 6.67, moeli o sebetsang hangata o pakeng tsa 2 le 4%. Tsena ke tsa bohlokoa haholo-holo ka lebaka la litšoaneleho tsa tsona tse babatsehang tsa ho lahlela. Litšepe tse bohlooho le li-ductile cast irons (tseo hape li bitsoang nodular cast iron kapa spheroidal graphite iron).
Ha graphite e le teng e le likaroloana tse nyenyane, tse pota-potileng, le tse ajoang hantle, phello ea eona e fokolang e nyenyane 'me litšepe tse joalo li tla ba le ductility e phahameng. Mofuta ona oa tšepe ea tšepe o bitsoa ductile kapa nodular iron kapa spheroidal graphite kapa feela SG iron. Mofuta ona oa graphite o ka finyelloa ka ho eketsa elemental magnesium kapa cerium kapa motsoako oa likarolo tse peli ho tšepe e entsoeng ka ho qhibilihisoa. Magnesium e kenngoa ka bongata ba 0.07 ho 0. 10% e lateloa ke ho eketsoa ha ferro-silicon ho khothalletsa graphitization. Nakong ea ho tiisa, magnesium e thusa ho ajoa ha graphite ho pholletsa le tšepe.
Aine ea ductile e na le karo-karolelano e betere ea matla ho boima, machinability e betere le boleng bo phahameng ba tšusumetso. Ho feta moo, likarolo tsa tšepe tsa ductile li hlahisoa ka mokhoa oa ho lahla moo taolo e betere ea sebopeho sa karolo e ka fihlellehang ha e bapisoa le ho thella. Ka hona, likarolo tse ngata tse kang crank shafts le li-rods tse kopanyang tse hlahisoang hangata ka "drop forging" li ntse li nkeloa sebaka ke li-ductile iron castings.
