Izikhiye Ezintathu Zokuthuthukisa Izinga le-Spheroidization And Ductile Iron Graphite Roundness

Kunezici eziningi ezithinta izinga le-spheroidization nokuzungeza kwensimbi ye-ductile cast. Okulandelayo kuhlaziya izinto ezithinta isilinganiso se-spheroidization kusuka ezicini ezintathu zokwakheka kwamakhemikhali, inqubo, nokulawulwa kokuqina:

Ukwakhiwa kwamakhemikhali

1. Carbon okulingana ne-silicon

I-Carbon ne-silicon yizinto eziyisisekelo ezithinta ukuzungeza kwama-nodular iron graphhe sphere. Ngaphansi kwezinga elithile lokupholisa nezimo zokufukamisela, ukukhuphula okulingana nekhabhoni kungakhuphula ukuzungeza kwendawo ye-graphite, kwandise amandla okuzondla, futhi kunciphise ama-carbides. Ngaphansi kwezimo ezithile ezilingana nekhabhoni, njengoba inani le-silicon landa, ikakhulukazi i-ductile yensimbi enkulu, kuzokhiqizwa i-graphite ehlukanisiwe. Ngakho-ke, esimweni lapho ingekho i-graphite entantayo, okulingana nekhabhoni kufanele kukhuliswe ngangokunokwenzeka; ngasikhathi sinye, okuqukethwe kwe-silicon kufanele kwehliswe ngangokunokwenzeka ngaphansi kwesiqinisekiso sezimo zokufukamela.

2. Magnesium

Ukulawulwa kokuqukethwe okusalayo kwe-magnesium kubaluleke kakhulu ukwenza ngcono ukuzungeza kwemikhakha ye-graphite. Lapho i-magnesium esebenzayo esebenzayo ingaphansi kuka-0.045%, ukwandisa inani le-magnesium esebenzayo esebenzayo kungathuthukisa ukuzungeza kwendawo ye-graphite; lapho i-magnesium esebenzayo esebenzayo inkulu kune-0.045%, kuzokhiqizwa i-graphite ye-metamorphic futhi ukuzungeza kwendawo ye-graphite kuzoncishiswa.

3. Umhlaba ongandile

Umhlaba ongajwayelekile unemiphumela emibili ezuzisayo ku-iron encibilikisiwe: eyodwa yi-desulfurization ne-degassing, edlala indima ye-spheroidization ne-spheroidization engaqondile; okwesibili kusebenzisana nezinto zokulandela umkhondo ukuqeda izici eziyingozi futhi kudlale uhlangothi oluhle. Zombili lezi zici zingathuthukisa ukuzungeza kwebhola le-graphite. Kodwa-ke, umhlaba osalile ngokweqile, ikakhulukazi i-ductile iron engxenyeni enkulu, uzokwehlisa isimo se-graphite, ikakhulukazi izigaxa. Ububanzi obulungile ngu-0.010% kuya ku-0.019%.

4. Landelela izakhi

Inani elithile le-antimony ne-bismuth elihlanganiswe nenani elifanele lomhlaba ongavamile lingathuthukisa ukuzungeza kwendawo ye-graphite futhi lithuthukise izakhiwo zemishini. Ibanga lokungeza elifanele: 0.0025 ～ 0.005%.

Inqubo

1. Ukwehliswa kwesithunzi

• I-ejenti ye-magnesium spheroidizing esindayo esindayo ingathuthukisa ukuzungeza kwama-graphite spheres kangcono kunokukhanya okungajwayelekile komhlaba we-magnesium spheroidizing agent. Ikakhulu ngenxa yekhono layo lokuqina le-desulfurization namandla anamandla okulwa nokubola.
• Uma ukukhanya okungajwayelekile komhlaba we-magnesium spheroidizing agent kulawulwa kahle futhi kulekelelwa ngezinto zokulandela ngomkhondo, kungaphinde kuthuthukise ukuzungeza kwemikhakha ye-graphite.
• Ikhwalithi yensimbi encibilikisiwe ingcono kunendlela yokungenisa ngaphansi kwesivumelwano, ngakho-ke futhi ingathuthukisa ukujikeleza kwama-graphite sphere.

2. Ukwelashwa nge-inoculation

• Inoculation eqinisiwe ingathuthukisa ukuzungeza kwamabhola we-graphite.
• Ukusetshenziswa kwama-anti-fading inoculants kungathuthukisa ukuzungeza kwamabhola we-graphite.
• Kusetshenziswa imidwebo yensimbi ye-ductile njenge-ejenti yokumboza i-spheroidization kungakha umgogodla we-graphite odlulayo ofana nokusakazeka kwe-graphite engaqediwe, kukhiqize ukuguquguquka kokuhlushwa kwesikhathi eside, kukhuphule kakhulu izinga le-nucleation elisebenzayo, futhi kuthuthukise ukuzungeza kwemikhakha ye-graphite. iziqu.
• Ukunciphisa izinga lokushisa elithululayo kungathuthukisa ukuzungeza kwamabhola we-graphite.

Isilawuli se-Coagulation

• Ukusebenzisa i-iron ebandayo kungathuthukisa ukuzungeza kwamabhola we-graphite.
• Ukusetshenziswa kwesihlabathi se-chromite kungathuthukisa ukuzungeza kwamabhola we-graphite.
• Ezinye izinyathelo ezingasheshisa ukupholisa futhi zinciphise isikhathi ngesikhathi sokuguqulwa kwe-eutectic yensimbi ye-ductile kungathuthukisa ukuzungeza kwemikhakha ye-graphite.

Sicela ugcine umthombo nekheli lale ndatshana ukuze uphinde uprintwe: Izikhiye Ezintathu Zokuthuthukisa Izinga le-Spheroidization And Ductile Iron Graphite Roundness

UMinghe Inkampani yeDie Casting anikezelwe ekukhiqizeni nasekuhlinzekeni ikhwalithi nokusebenza okuphezulu Izingxenye Zokulingisa (izingxenye zensimbi zensimbi zokufa zisebenza ikakhulukazi zibandakanya I-Thin-Wall Die Casting,I-Hot Chamber Die Casting,Cold Chamber die Casting), Insizakalo Eyindilinga (Insiza Yokulingisa,ICnc Machining,Ukwenza Okubandayo, Surface Treatment) .Noma ikuphi ukusakazwa kwe-Aluminium die, i-magnesium noma i-Zamak / zinc die casting nezinye izidingo zokuphosa zamukelekile ukuxhumana nathi.

Ngaphansi kokulawulwa kwe-ISO9001 ne-TS 16949, Zonke izinqubo zenziwa ngamakhulu emishini esezingeni eliphakeme yokufa, imishini ye-5-axis, nezinye izikhungo, ezisukela kuma-blasters kuya kumishini yokuwasha ye-Ultra Sonic.Minghe akagcinanga ngemishini esezingeni eliphezulu kepha futhi unobuchwepheshe iqembu lonjiniyela abanolwazi, ama-opharetha nabahloli ukwenza ukwakheka kwekhasimende kugcwaliseke.

Umenzi wenkontileka yokufa kwabasikiwe. Amandla afaka izingxenye ezibandayo ze-aluminium die casting ezivela ku-0.15 lbs. kuye ku-6 lbs., Ukusetha ushintsho olusheshayo, nemishini. Izinsizakalo ezingezwe ngenani zifaka phakathi ukupholisha, ukudlidliza, ukuphazamisa, ukuqhumisa ngokudubula, ukupenda, ukuhlobisa, ukumboza, ukuhlangana nokusetshenziswa kwamathuluzi. Izinto zokusebenza ezisetshenzisiwe zifaka ama-alloys afana no-360, 380, 383, no-413.

I-Zinc die casting design usizo / izinsizakalo zobunjiniyela ezihambisanayo. Umenzi wangokwezifiso we-precision zinc die castings. Ukusakazwa okuncane, ukukhishwa kwengcindezi ephezulu, ukusikeka kwesikhunta esiningi, ukujikijelwa kwesikhunta okuvamile, ukufefa kwamayunithi kanye nokuzimela okuzimele kanye nokuvalwa okuvaliwe komgodi kungenziwa. Ama-Castings angenziwa ngobude nobubanzi obufinyelela ku-24 in. Ku +/- 0.0005 in. Ukubekezelelana.  

I-ISO 9001: Umkhiqizi oqinisekisiwe ka-2015 we-die cast magnesium, Amandla afaka i-high-pressure magnesium die casting up to 200 ton chamber hot & 3000 ton cold chamber, designing designing, polishing, molding, machining, powder & liquid paint, QA full with CMM amakhono , inhlangano, ukupakisha nokulethwa.

Kuqinisekiswe i-ITAF16949.
