Mokhoa oa ho ntlafatsa thepa ea mochini oa "Gray Cast Iron Castings"

U ka ntlafatsa litšobotsi tsa mochini oa tšepe e putsoa joang?

Grey cast iron ke motsoako oa tšepe ea khabone moo karolo e kaholimo e leng putsoa. Ka taolo ea sebopeho le ts'ebetso ea ho tiisa, khabone e hlaha haholo ka sebopeho sa flake graphite. Sebopeho sa tšepe sa tšepe se entsoe ka tšepe ea 'mala o moputsoa,' mala oa tšepe le moeli oa lijo-thollo.

Boteng ba graphite ea flake ka tšepe e putsoa e senya ts'ebetsong ea mantlha ea tšepe mme e etsa tšepe ea bohlooho hore e be sesebelisoa. Empa tšepe e bohlooho ke e 'ngoe ea lisebelisoa tsa tšepe tsa pele le tse sebelisoang haholo. Tšepe e entsoeng ka bohlooho e na le litšobotsi tse ngata. Nako e telele, ts'ebetsong ea tlhahiso, re akaretse mehato e meng e tloaelehileng ho ntlafatsa matla a tensile ea tšepe e bosootho. Tlas'a maemo a mang, re ka boela ntlafatsa tshebetso itšeha, apara ho hanyetsa le tshebetso makala absorption tsa tšepe ea bohlooho liheloe.

Ha ho hlahisoa lihlahisoa tsa 'nete, boholo ba tšepe e bohlooho ke hypoeutectic. Ka hona, ho ntlafatsa matla a eona a thata, lintlha tse latelang li lokela ho etsoa ka hohle kamoo ho ka khonehang:

1) Tiiso ea tšepe e bohlooho e na le li-dendrite tsa mantlha tsa austenite nakong ea ho tiisa
2) Fokotsa palo ea graphite ea eutectic mme oe etse ka mokhoa o ts'oanang o tsamaisoa ka mofuta o motle oa mofuta oa A
3) Eketsa palo ea lihlopha tsa eutectic
4) Nakong ea phetoho ea austenite eutectoid, tsohle li fetoha pearlite matrix e ntle

Ka tlhahiso ea 'nete ea cast cast cast iron, hangata re sebelisa mehato e latelang ho fihlela sephetho se kaholimo:
1) Khetha lik'hemik'hale tse utloahalang
2) Fetola sebopeho sa tefiso
3) tšepe e qhibilihisitsoeng e fetotsoeng
4) Phekolo ea ente
5) Trace kapa low alloying
6) Phekolo ea mocheso
7) Eketsa sekhahla se pholileng nakong ea phetoho ea eutectoid

Mehato e tobileng e lokelang ho nkuoa e ipapisitse le mofuta oa ho betloa ha tšepe e putsoa, ​​thepa e hlokahalang le maemo a ikhethileng a tlhahiso. Leha ho le joalo, hangata hoa hlokahala ho nka mehato e 'meli kapa ho feta ho fihlela ts'ebetso e lakatsehang ea tšepe ea tšepe.
