Mocheso Phekolo Process Of Cast Tšepe

Ntle le khetho e nepahetseng ea metsoako e metle ea tlhahiso ea tšepe ea tšepe ho fumana sebopeho se reriloeng esale pele, kalafo ea mocheso hape ke tsela ea bohlokoa ea ho ntlafatsa le ho ntlafatsa sebopeho sa matrix ho ntlafatsa ts'ebetso ea ts'epe ea tšepe. Phekolo ea mocheso oa tšepe ea tšepe le ho kenella ka tšepe e chesang li na le ho tšoana le phapang. Kalafo ea mocheso oa tšepe ea tšepe ha e na ho ntlafatsa morpholoji le kabo ea graphite ka sebopeho sa mantlha.

Bakeng sa tšepe e putsoa, ​​khatello ea maikutlo e bakoang ke flake graphite ke eona ntho e ka sehloohong ts'ebetsong ea tšepe ea tšepe. Ka hona, matla a matlafatsang a kalafo ea mocheso ho tšepe e bohlooho ha a bohlokoa ho feta tšepe le tšepe ea ductile. Ka hona, ts'ebetso ea kalafo ea mocheso oa tšepe ea Youkou e kenyelletsa annealing le ho tloaela maemo. Bakeng sa tšepe ea ductile, kaha graphite e chitja, phello ea ho arohana ha matrix e fokotsehile haholo, mme sebopeho sa matrix se ka sebelisoa ka botlalo ke kalafo ea mocheso, e ka ntlafatsang haholo litšobotsi tse chitja tsa mochini.

Ka hona, tšepe ea ductile e tšoana le tšepe, 'me lits'ebetso tsa eona tsa kalafo ea mocheso li kenyelletsa ho koala, ho tloaela, ho tima le ho futhumatsa, ho tima mocheso o mongata, ho tima mocheso oa ho futhumatsa le kalafo ea mocheso oa lik'hemik'hale.

Mocheso kalafo thulaganyou e lahleloa tšepe

1. Ho imolla khatello ea maikutlo

Ka lebaka la botenya bo sa lekanang ba lebota, matla a phello le khatello ea maikutlo li tla hlahisoa nakong ea ho futhumatsa, ho futhumatsa le phetoho ea mohato. Ntle le moo, likarolo tse kholo li na le khatello ea maikutlo e setseng kamora ho sebetsa, mme likhatello tsena tsohle tsa kahare li tlameha ho felisoa. Mocheso o tloaelehileng oa ho futhumatsa bakeng sa phokotso ea khatello ea maikutlo ke 500 ～ 550 ℃, nako ea ho ts'oara ke 2 ～ 8h, ebe ho futhumatsa sebōpi (tšepe e putsoa) kapa ho futhumatsa moea (ductile iron). Ho sebelisa ts'ebetso ena ho ka felisa khatello ea maikutlo ea kahare ea 90-95%, empa sebopeho sa tšepe e sa fetoheng. Haeba mocheso o feta 550 ℃ kapa nako ea ho ts'oara e telele haholo, e ka baka graphitization mme ea fokotsa matla le thatafalo ea ho betsa.

2. Tlosa mocheso o phahameng oa graphitization o kenang molomong o mosoeu oa ho lahla

Ha ho lahla ho pholile, karolo e kaholimo le karolo e tšesaane hangata e na le melomo e tšoeu. Sebopeho sa molomo o mosoeu se thata ebile se brittle, se na le ts'ebetso e mpe ea ho e lokisa ebile e bonolo ho eboloa. Ka hona, mokhoa oa ho koala (kapa ho tloaela) o tlameha ho sebelisoa ho felisa sebopeho sa molomo o mosoeu. Ts'ebetso ea annealing ke: ho futhumatsa ho 550-950 ° C bakeng sa lihora tse 2 ho isa ho tse 5, ebe sebōpi se pholile ho fihlela 500-550 ° C ebe moea o pholisa. Nakong ea mocheso o phahameng o ts'oereng cementite le eutectic cementite li bola ka graphite le A, 'me cementite ea bobeli le eutectoid cementite le tsona lia senyeha nakong ea pholileng, mme ts'ebetso ea graphitization e etsahala. Ka lebaka la ho senyeha ha cementite, thatafalo ea fokotseha, ka tsela eo e ntlafatsa ts'ebetso ea ts'ebetso.

3. Tloaelo ea tšepe ea ductile

Morero oa ho tiisa tšepe ea ductile ke ho fumana sebopeho sa pearlite matrix, le ho ntlafatsa lithollo tsa kristale le sebopeho sa junifomo ho ntlafatsa thepa ea mochini oa castings. Ka linako tse ling ho tloaela ho etsa lintho tse ling hape ke tokisetso ea ho tima tšepe ea ductile. Normalizing e arotsoe ka phahameng mocheso normalizing le tlaase mocheso normalizing. Mocheso o phahameng oa mocheso o tloaelehileng ha o fete 950-980 ℃, 'me mocheso o tlase o tloaelehileng o futhumetse ka kakaretso ho futhumatsa mocheso o tloaelehileng oa 820-860 ℃. Kamora ho tloaela maemo, ho hlokahala hore batho ba bane ba sebetsane le eona ho felisa khatello ea maikutlo e kahare e hlahang nakong ea tloaelo.

4. Ho tima le ho futhumatsa tšepe ea ductile

Bakeng sa ho ntlafatsa litšobotsi tsa mochini oa tšepe ea ductile, hangata castings e futhumetse ho 30-50 ° C kaholimo ho Afc1 (Afc1 e emetse mocheso oa hoqetela oa sebopeho nakong ea ho futhumatsa), ebe e tima ka oli kamora ho boloka mocheso ho fumana sebopeho sa martensitic. Bakeng sa ho fokotsa ka nepo khatello ea masalla kamora ho tima, khalefo e lokela ho etsoa kamora ho tima. Sebopeho sa tempering e nang le mocheso o tlase se na le martensite e nang le masale a bainite le nodular graphite. Sebopeho sena se na le khanyetso e ntle ea ho roala 'me se sebelisetsoa likarolo tse hlokang ho itšireletsa holimo ho matla le matla a holimo. Mocheso o futhumetseng oa mocheso o mahareng ke 350-500 ℃. Sebopeho kamora ho halefa se na le `` troostite '' e nang le `` graphite '' e chitja, e loketseng likarolo tse teteaneng tse hlokang ho hanela ho apara hantle, botsitso le ho saroloha. Mocheso o phahameng mocheso oa tempering ke 500-60D ℃, sebopeho kamora ho halefisoa ke Soxhlet e entsoeng ka spheroidal graphite, e nang le motsoako o motle oa ho ba thata le matla, ka hona e sebelisoa haholo tlhahiso.

5. Ho tima mocheso o mongata oa tšepe ea ductile

Ductile iron e ka fumana matla a phahameng kamora ho ts'oaroa, ha e ntse e na le polasetiki e ntle le ho ba thata. Khetho ea mocheso o futhumatsang bakeng sa ho tima mocheso o mongata haholo e nka hore sebopeho sa mantlha se entsoe ka A ka botlalo, ntle le masalla a F, mme ka nako e ts'oanang, ho qoba kholo ea lithollo tsa kristale. Mocheso oa ho futhumatsa ka kakaretso o 30-50 ° C kaholimo ho Afc1, 'me mocheso oa kalafo ea isothermal ke 0-350 ° C ho netefatsa hore sebopeho se tlase sa bainite se nang le thepa e phethahetseng ea mochini se fumaneha. Rare ea lefatše ea magnesium aluminium ductile iron kamora ho tima isothermal σb = 1200 ～ 1400MPa, αk = 3 ～ 3.6J / cm2, HRC = 47 ～ 51. Empa hoa lokela ho hlokomeloa hore ts'ebetso ea tempering e lokela ho eketsoa kamora ho baleha.

6. Ho thatafala ha bokaholimo

Bakeng sa ho ntlafatsa bokaholimo ba bokaholimo, roala ho hanyetsa le matla a mokhathala a li-castings tse ling, ho tima sefahleho ho ka sebelisoa. Lisebelisoa tsa tšepe tse bosoeu le li-castle tsa ductile li ka thatafala holimo. Ka kakaretso, ho sebelisoa ha matla a ho futhumatsa a maqhubu a phahameng (a mahareng) le ho thatafala ha motlakase ka holim'a metsi ho sebelisoa.

7. Kalafo ea mocheso oa lik'hemik'hale

Bakeng sa li-castings tse hlokang ho itšireletsa ka holim'a metsi, ho hanyetsa oxidation, le ts'enyeho ea ts'enyeho, ho ka sebelisoa lits'ebetso tsa kalafo ea mocheso oa lik'hemik'hale tse ts'oanang le tšepe, joalo ka khase "target =" _ blank "> khase e bonolo ea chlorine, chlorination, boronizing, sulfurizing le kalafo tse ling.
