Igwe ikuku n'oge usoro nhazi bụ isi ihe maka nkà na ụzụ MIM, ọ na-ekpebi nsonaazụ sintering na arụmọrụ ikpeazụ nke ngwaahịa.Taa, anyị ga-ekwu maka ya, ikuku nke Sintering.
Ọrụ nke ikuku ikuku:
1) Mpaghara Dewaxing, wepụ mmanụ mmanu na ahụ ndụ ndụ;
2) Belata oxides ma gbochie oxidation;
3) Zere decarburization na carburization ngwaahịa;
4) Zere oxidation nke ngwaahịa na mpaghara jụrụ oyi;
5) Na-enwe nrụgide dị mma na ọkụ ọkụ;
6) Nọgidenụ na-anọgidesi ike nke sintering results.
Nhazi nke ikuku ikuku:
1) Oxidizing ikuku: dị ọcha Ag ma ọ bụ Ag-oxide ihe mejupụtara na sintering nke oxide ceramik: Ikuku;
2) Mbelata ikuku: ikuku ikuku nke nwere H2 ma ọ bụ ihe CO: ikuku hydrogen maka cemented carbide sintering, ikuku nke nwere hydrogen maka ígwè dabeere na ígwè na ọla kọpa nke ntụ ntụ metallurgy akụkụ (amonia decomposition gas);
3) Inert ma ọ bụ na-anọpụ iche ikuku: Ar, He, N2, Vacuum;
4) ikuku ikuku: nwere ihe dị elu nke na-eme ka carburization nke anụ ahụ dị nro, dị ka CO, CH4, na gas Hydrocarbon;
5) ikuku dabeere na Nitrogen: Na nnukwu nitrogen ọdịnaya sintering ikuku: 10% H2 + N2.
Gas na-agbanwe agbanwe:
Iji gas hydrocarbon (gasị eke, mmanụ mmanụ mmanụ, coke oven gas) dị ka akụrụngwa, iji ikuku ma ọ bụ uzuoku mmiri na-emeghachi omume na oke okpomọkụ, yana nsonaazụ H2, CO, CO2, na N2.Obere mmanụ gas agwakọta nke CH4 na H2O.
Gas Exothermic:
Mgbe ị na-akwadebe gas na-agbanwe agbanwe, gas na-emepụta ihe na ikuku na-agafe na onye ntụgharị n'otu akụkụ.Ọ bụrụ na oke nke ikuku na akụrụngwa gas dị elu, okpomọkụ a tọhapụrụ n'oge mmeghachi omume zuru ezu iji nọgide na-enwe okpomọkụ mmeghachi omume nke onye ntụgharị, na-enweghị mkpa maka mpụga na reactor kpo oku, nke na-akpata mgbanwe gas.
Gas endothermic:
Mgbe ị na-akwadebe gas na-agbanwe agbanwe, ọ bụrụ na ikuku ikuku na gas dị ala dị ala, okpomọkụ a na-ahapụ n'oge mmeghachi omume ezughị iji nọgide na-enwe okpomọkụ mmeghachi omume nke onye na-eme mgbanwe, na reactor kwesịrị inye ya okpomọkụ site n'èzí.A na-akpọ gas endothermic gas na-esi na ya pụta.
NkeIkuku Carbon nwere ikebụ ihe jikọrọ carbon carbon nke ikuku, nke kwekọrọ na ihe dị na carbon na ihe mgbe ikuku na ihe ndị na-eme ka ọ dị na carbon na-erute mmeghachi omume mmeghachi omume (enweghị carburization, enweghị decarburization) na okpomọkụ.
Na nkeIgwe ikuku nwere ike ịchịkwabụ okwu n'ozuzu maka ikuku gas a kwadebere abanye n'ime sistemu nke sisitemu iji chịkwaa ma ọ bụ mezie ọdịnaya carbon nke nchara siri ike.
Igodo iji chịkwaa ọnụọgụ CO2 na H2Ona ikuku:
1) Njikwa nke H2O ego-igirigi ebe
Ebe Irigi: Okpomọkụ nke vepo mmiri dị na mbara igwe na-amalite ịgbanye n'ime alụlụụ n'okpuru nrụgide ikuku ọkọlọtọ.Ka ọdịnaya mmiri dị na mbara igwe, ka igirigi dị elu.Enwere ike iji mita ebe igirigi tụọ ebe igirigi: nha nnabata nke mmiri na-eji LiCI.
2) Jikwaa ọnụọgụ CO2 wee tụọ ya site na nyocha nnabata infrared.
