Carbide e entsoeng ka samente le tšepe ea lebelo le phahameng ke lihlahisoa tse tloaelehileng tse ka tlaase tsa refractory metal tungsten (W), ka bobeli li na le thepa e ntle ea thermodynamic, 'me li ka sebelisoa ho etsa lisebelisoa tsa ho itšeha, liforomo tse batang le li-molds tse chesang, joalo-joalo. mefuta e fapaneng ea lisebelisoa tsa tse peli, li boetse li fapana ho ea ka thepa ea mochini le ts'ebeliso.
1. Khopolo
Carbide e entsoeng ka samente ke lisebelisoa tsa alloy tse entsoeng ka carbide ea tšepe e refractory joalo ka phofo ea tungsten carbide (WC) le tšepe e kopanyang joalo ka phofo ea cobalt. Lebitso la Senyesemane ke Tungsten Carbide/Cemented Carbide. Likahare tsa eona tse phahameng tsa mocheso oa carbide li phahame ho feta tsa bophahamo ba tšepe ea lebelo le phahameng la.
Tšepe ea lebelo le phahameng ke tšepe e phahameng ea carbon high-alloy e entsoeng ka bongata bo boholo ba tungsten, molybdenum, chromium, cobalt, vanadium le lintho tse ling, haholo-holo tse entsoeng ka tšepe ea carbide (e kang tungsten carbide, molybdenum carbide kapa vanadium carbide) le matrix ea tšepe, e nang le carbon content ea 0,7 % -1.65%, palo eohle ea lisebelisoa tsa alloying ke 10% -25%, 'me lebitso la Senyesemane ke High Speed Steels (HSS).
2. Tshebetso
Ka bobeli li na le litšobotsi tsa boima bo phahameng, matla a phahameng, boima bo botle, boima bo bofubelu, ho hanyetsa ho roala, ho hanyetsa mocheso le ts'ebetso ea ts'ebetso, 'me litšobotsi tsena li tla fapana ka lebaka la limaraka tse fapaneng. Ka kakaretso, ho thatafala, boima bo bofubelu, ho hanyetsa ho roala le ho hanyetsa mocheso oa carbide e entsoeng ka samente e molemo ho feta ea tšepe ea lebelo le phahameng.
3. Theknoloji ea tlhahiso
Ts'ebetso ea tlhahiso ea carbide e entsoeng ka samente e kenyelletsa haholo ts'ebetso ea metallurgy ea phofo, theknoloji ea ho bopa ente kapa mokhoa oa khatiso oa 3D.
Mekhoa ea tlhahiso ea tšepe e lebelo le phahameng e kenyelletsa theknoloji ea setso ea ho lahla, theknoloji ea remelting ea electroslag, theknoloji ea metallurgy ea phofo le theknoloji ea ho bopa ente.
4. Sebelisa
Le hoja ka bobeli ba ka etsa lithipa, hlobo ea mosebetsi o chesang le hlobo ea mosebetsi o batang, ts'ebetso ea bona e fapane. Lebelo la ho itšeha la lisebelisoa tse tloaelehileng tsa carbide ke makhetlo a 4-7 ho feta a lisebelisoa tse tloaelehileng tsa tšepe tse lebelo le phahameng, 'me bophelo ba ts'ebeletso bo bolelele ba makhetlo a 5-80. Mabapi le hlobo, bophelo ba ts'ebeletso ea carbide e entsoeng ka samente e shoa ka makhetlo a 20 ho isa ho 150 ho feta ea tšepe ea lebelo le phahameng. Ka mohlala, bophelo ba tšebeletso ea hot heading extrusion dies e entsoeng ka tšepe ea 3Cr2W8V ke makhetlo a 5,000. Ts'ebeliso ea li-heading tse chesang extrusion e shoa e entsoeng ka carbide ea YG20 Bophelo ba ts'ebeletso ke makhetlo a 150,000.
