Kedu usoro anọ dị na usoro ịmegharị agụụ nke Cemented Carbid

Carbide cimentvacuum sintering bụ usoro a na-eme sintering na nrụgide dị n'okpuru ikuku ikuku.Usoro a na-agụnye mwepụ nke plasticizer, degassing, siri ike nkebi sintering, mmiri mmiri mmiri sintering, alloying, densification, na mgbasa mmiri ozuzo.Ka anyị leba anya na usoro anọ bụ isi nke cemented carbide vacuum sintering:

① Ogbo mwepụ nke plasticizer

Ogbo mwepụ nke plasticizer na-amalite site na ọnụ ụlọ okpomọkụ wee rute ihe dịka 200 Celsius.The gas adsorbed n'elu nke ntụ ntụ irighiri na billet na-ekewapụ n'elu nke ahụ site okpomọkụ na-esi na billet na-agbapụ na-aga n'ihu.A na-ekpo ọkụ plasticizer na billet ka ọ gbanarị na billet.Ịnọgide na-enwe ọkwa dị elu nke agụụ na-eme ka ntọhapụ na mgbapụ nke gas.Ụdị dị iche iche nke ndị na-emepụta ihe na-agbanwe mgbanwe okpomọkụ na arụmọrụ dịgasị iche iche, mmepe nke usoro iwepụ plasticizer kwesịrị ikpebi dị ka ọnọdụ dị iche iche nke ule ahụ si dị.N'ozuzu plasticizer gasification okpomọkụ dị n'okpuru 550 ℃.

② Agba agbagoro agba

Pre-sintering ogbo na-ezo aka elu okpomọkụ sintering tupu tupu sintering, nke mere na chemical oxygen na ntụ ntụ ahụ na carbon Mbelata mmeghachi omume n'ịwa carbon monoxide gas na-ahapụ ndị pịa billet, ma ọ bụrụ na nke a gas enweghị ike ewepu mgbe mmiri mmiri na-apụta, ọ ga-aghọ ihe fọdụrụ pore mechiri emechi na alloy, ọ bụrụgodị na nrụgide sintering, ọ siri ike ikpochapụ.N'aka nke ọzọ, ọnụnọ nke oxidation ga-emetụta nke ukwuu wettability nke mmiri mmiri na-agbasi ike na-emecha na-emetụta usoro densification nkecemented carbide.Tupu usoro mmiri mmiri apụta, a ga-ekpochasị ya nke ọma na enwere ike iji oghere kachasị elu mee ihe.

③ Elu okpomọkụ sintering ogbo

Okpomọkụ na-ekpo ọkụ na oge nkwụsịtụ bụ usoro usoro dị mkpa maka densification nke billet, nhazi nke ihe owuwu otu na ịnweta ihe ndị achọrọ.Okpomọkụ na-ekpo ọkụ na oge nkwụsịtụ na-adabere na ngwakọta alloy, nha ntụ ntụ, ike na-egweri nke ngwakọta na ihe ndị ọzọ, ma na-achịkwa ya site na nhazi nke ihe niile.

④ Ogbo jụrụ oyi

Oge nju oyi bụ ebe ọnụ ọgụgụ dị jụụ na-emetụta nhazi na nhazi nke njikọ njikọ nke alloy na-emepụta nrụgide dị n'ime.Ọnụego jụrụ oyi kwesịrị ịdị na steeti a na-achịkwa.Ịmepụta ikpo ọkụ isostatic na-ekpo ọkụ bụ usoro ọhụụ ọhụrụ, nke a makwaara dị ka obere nrụgide, nke a na-agbanye ngwaahịa ahụ na nrụgide ụfọdụ nke gas iji kwalite densification n'okpuru ọnọdụ nke degassing na-agwụ agwụ, pores n'elu elu nke billet. emechiela ya, usoro ihe nkedo na-anọgide na-abụ mmiri mmiri.
