1, umthelela wosayizi wezinhlayiyana ze-ejenti ye-carburizing

Ukusetshenziswa kwei-ejenti ye-carburizingInqubo ye-carburizing ihlanganisa inqubo yokusabalalisa ukuchithwa kanye nenqubo yokulahlekelwa yi-oxidation, i-ejenti yokungcwaba enosayizi wezinhlayiyana ezihlukene, izinga lokuhlakazeka kwe-oxidation kanye nezinga lokulahlekelwa kwe-oxidation lihlukile, futhi izinga lokumuncwa kwe-ejenti ye-carburizing lincike ekuhlakazweni kwe-ejenti yokungcwaba ngesilinganiso sokukhula kokusabalalisa kanye nesivinini sokubala sokulahleka kobuchwepheshe be-oxidation Ukuphathwa okuphelele, ngokuvamile, izinhlayiya ze-carburizing ezincane, Ijubane lokusabela lokuqedwa liyashesha, ukulahlekelwa kanye nesivinini sikhulu;I-carburizer inosayizi omkhulu wezinhlayiyana, izinga lokuncibilika kancane kanye nezinga lokukhuphuka kokulahleka okuncane.

2, umthelela we-iron ewuketshezi enyakazayo ngesilinganiso sokumuncwa kwe-ejenti ye-carburizing

Ukuyaluza kukhuthaza ukuhlakazeka nokusabalalisa ikhabhoni ukuze kugwenywe ukushiswa kwensimbi entantayo phezu koketshezi.Ngaphambi kwei-ejenti ye-carburizingingahlakazwa ngokuphelele, isikhathi esishukumisayo side futhi izinga lokumunca liphezulu.Ukunyakazisa kunganciphisa isikhathi sokufakwa kwe-carburizing, kufinyeze umjikelezo wokukhiqiza, futhi kugweme ukushiswa kwezinto ezixutshwa kunsimbi eshisayo.Kodwa-ke, isikhathi esishukumisayo side kakhulu, i-carbon encibilikisiwe oketshezini lwensimbi enyakazayo izokwandisa ukulahlekelwa kwekhabhoni kunomthelela omkhulu.Ngakho-ke, ukuphathwa kwesikhathi esifanele sokuxuba kwensimbi ewuketshezi kufanele kube ukuqinisekisa ukuthi i-carburizer ingancibilika ngokuphelele.

　　3, umthelela wezinga lokushisa ngesilinganiso sokumuncwa kwe-carburizer

Ngokohlaziyo oluvela kumbono we-partial mechanics kanye ne-thermodynamics, i-oxidation ye-liquid iron ihlobene nokushintshashintsha kwezinga lokushisa kokusebenza kohlelo lwe-C-Si-O, okungukuthi, i-O eku-liquid iron izoba nokusabela okungekuhle nge-C kanye ne-Si. .Izinga lokushisa elilinganayo liyashintsha nokuqukethwe kuka-C no-Si.Ngakho-ke, lapho izinga lokushisa lokusebenza lokulinganisa lingaphezulu, izinga lokumuncwa kwe-carburant lingancishiswa.Lapho izinga lokushisa le-carburizing lingaphansi kwezinga lokushisa elilinganayo le-ambient, ukuncibilika okugcwele kwekhabhoni kuyehla ngenxa yezinga lokushisa eliphansi uma kuqhathaniswa, futhi izinga lokuthuthuka lokuncibilika kwekhabhoni nokusabalalisa liyehla, ngakho isivuno sibuye sibe phansi;Izinga lokushisa le-Carburizing ezingeni lokushisa lokulawula ibhalansi, izinga lokumunca i-ejenti ye-carburizing liphezulu.

4, umthelela wokwengezwa kwe-ejenti ye-carburizing

Ngokwezinga lokushisa kanye nokwakheka kwamakhemikhali, ezinye uketshezi lwekhabhoni zinesimo esifanayo esingaguquki sokugxiliswa kwensimbi.Ukuncibilika kwekhabhoni ensimbini engu-([C] % = 1.30.0257 t – 0.31% [Si] 0.33 [P] % 0.45 [% S] 0.028 [Mn %] ngezinga lokushisa lensimbi (t). Ngaphansi kwesilinganiso esithile izinga lokugcwala, lapho kungezwa i-carburizer eyengeziwe, isikhathi eside esidingekayo sokuhlakazeka nokusabalalisa, kukhulu ukulahlekelwa okuhambisanayo, kanye nezinga lokumunca lizoncishiswa.

5, umthelela wokwakheka kwamakhemikhali e-iron liquefaction ngezinga lokumuncwa kwe-carburizer

Uma i-iron ewuketshezi iphezulu kokuqukethwe kwekhabhoni yokuqala, izinga lokumunca le-carburant encibilikisiwe lihamba kancane, izinga lokumunca le-carburant lincane, futhi ukushiswa okukhulu kuncane.Lapho i-carbon content yokuqala ye-iron ewuketshezi iphansi ngokuqhathaniswa, isimo siyahlehla.Ngaphezu kwalokho, i-silicon nesibabule esixazululweni sensimbi kuvimbe ukumuncwa kwekhabhoni futhi kwanciphisa izinga lokumuncwa kwezithuthukisi zekhabhoni.IManganese inomthelela ekumunceni ikhabhoni futhi ikhuphule izinga lokumuncwa kwezithuthukisi zekhabhoni.Ngokwezinga lethonya, i-silicon inkulu kakhulu, i-manganese eyesibili, i-carbon, isulfure incane.Ngakho-ke, enqubweni yangempela yokukhiqiza nokuthuthukiswa, i-manganese kufanele yengezwe kuqala, bese kuba ikhabhoni, bese kuba i-silicon.
