Umhlaba ongavamile ungathuthukisa ngempumelelo ubunzima bensimbi yensimbi

Njengoba sonke sazi, ukufaka inani elifanele lezinto zomhlaba ezingavamile ezintweni zensimbi kuzoba nomthelela omkhulu ekwakhiweni nasekusebenzeni kwendaba. Imvamisa izinto zomhlaba ezingandile ngensimbi zengezwa ngo-0.05% ~ 0.20%. Ngoba isilinganiso semisebe ye-athomu yomhlaba ongajwayelekile kuyinsimbi yeqa kakhulu i-15%, nomehluko wobumbano phakathi komhlaba ongavamile nensimbi kukhulu kakhulu, lokhu akulungele ukwakheka kwesisombululo esiqinile, ngakho-ke ukuncibilika komhlaba okungajwayelekile ensimbi liphansi kakhulu. Iningi lezakhi zomhlaba ezingandile ngensimbi zikhona ngendlela yamakhemikhali omhlaba angavamile, ikakhulukazi ama-oxide womhlaba angavamile nama-sulfide womhlaba angavamile.

I-Xi'an Aeronautical Vocational and Technical College yenze ucwaningo ngomphumela wokwengeza izinto ezingavamile zomhlaba ukwenza insimbi ekwakhiweni nasekusebenzeni kwayo. Basebenzise insimbi ye-ZG35CrMnSi njengezinto zokuhlola, futhi okufakiwe okungajwayelekile komhlaba okusetshenzisiwe bekuxubekile umhlaba ongajwayelekile. Uma kubhekwa ukuthi impahla yokuhlola iqukethe inani elithile lesibabule Futhi ukulahleka lapho kunezelwa izinto ezingavamile zomhlaba, ububanzi bokwengezwa komhlaba okungajwayelekile ngu-0.23% ~ 0.38%, lokhu kufakwa kubhekise enanini eliphelele lomhlaba ongajwayelekile ongezwe ensimbi encibilikisiwe ngesikhathi sokuncibilika. Qhathanisa ukwakheka nokusebenza kwamasethi amabili amasampula ngezinto ezingenawo umhlaba ezingavamile. Ukusakazwa kwensimbi kuncibilikiswa esithandweni esiphakathi sokungeniswa, futhi ukusakazwa kulungiswa ngokufaka imali. Ngemuva kwalokho ucezu lokuhlola lufudunyezwa lube ngu-900 ° C + 670 ° C ukuze kuphole umoya, bese lushiswa luye ku-890 ° C ngokucisha uwoyela; bese kuthi 570 ~ 630 ° C umlilo.

Imiphumela yokuqhathanisa ikhombisa ukuthi umhlaba ongajwayelekile awunamphumela omncane emandleni ensimbi eyakhiwe, kepha unomthelela omkhulu ekuqineni kwensimbi eyinsimbi. Ubulukhuni bomthelela bukhuphuke ngo-43%, kanti izinga lokunweba lenyuswa ngo-13.3%. Ukuhlolwa kweMicrostructure kukhombisa ukuthi i-sorbite enesakhiwo sensimbi yensimbi engenazo izakhi zomhlaba ezingavamile iqhelekile, futhi usayizi wayo wokusanhlamvu ucishe ube yi-5; phakathi kwazo, izigaxa ezimpunga kukhona ukufakwa kwe-MnS, okungasatshalaliswa kuyo yonke indawo ehloliwe. Ngokuvamile, i-morphology ye-MnS iningi i-angular. Isampula lokwakheka kwensimbi enezinto zomhlaba ezingavamile lilingana futhi li-sorbite emnene, futhi usayizi wokusanhlamvu ucishe ube ngu-8-9. Kukhombisa ukuthi ukwakheka kwensimbi yensimbi kungacolisiswa ngemuva kokungeza izinto zomhlaba ezingavamile.

Ngaphezu kwalokho, ngemuva kokungeza izakhi zomhlaba ezingavamile, umphumela wensimbi owonakalisayo awusobala, kepha unethonya elikhulu kwi-morphology ye-MnS. Lapho izakhi zomhlaba ezingavamile zingangezwa, i-MnS ensimbi isesimweni semichilo noma amabhlogo anemiphetho namakhona; ngemuva kokungeza izakhi zomhlaba ezingandile, i-sulfide icishe ibe yindilinga, futhi ukusatshalaliswa kuqhathaniswa kuhlakazeke ngokuhlobene nesampula ngaphandle kwezakhi zomhlaba ezingavamile, kepha kuphela ezindaweni ezimbalwa Ungabona ukuqaqa noma ukuvimba ukufakwa kwe-sulfide. Ekuqhekekeni kwesampula ngaphandle kwezakhi zomhlaba ezingavamile, i-MnS igxiliwe futhi yenziwa nge-dendritic. Ukwephuka kwendawo yokufakwa kwe-MnS ikakhulukazi ukuphuka okuphakathi, futhi imifantu yesibili yangaphakathi iyabonakala endaweni.

Kumasampuli anezakhi zomhlaba ezingavamile, ukuphuka kungukuqhekeka kwe-ductile transgranular. Ngisho nasendaweni lapho kugxilwa khona ama-sulfide, insimbi ye-matrix isaphuka i-ductile transgranular. Insimbi yensimbi engezwe ngezinto zomhlaba ezingavamile iqeda ama-dendritic sulfide futhi iwashintsha abe yizinduku eziyindilinga noma ezingezona ezemvelo kanye nama-sulfide amakhulu omhlaba angavamile, azuzisa ekuthuthukiseni ukuqina.

Ucwaningo luye lwabonisa ukuthi umgomo wokucwengwa kwezinto ezingavamile komhlaba kungenzeka ngenxa yezizathu ezilandelayo:

(1) Ama-sulfide ne-oxide inclusions akhiwa ngokungeza izinto ezingavamile zensimbi kungaphenduka i-crystal nuclei yensimbi engeyona eyokuzenzakalela, engacwilisa amakristalu alinganayo futhi ifinyeze izifunda ezinamakholomu akhazimulayo.

(2) Ukuncibilika kwezakhi zomhlaba ezingavamile esigabeni esiqinile kuncane kakhulu. Lapho insimbi encibilikile iqinisiwe, imihlaba engajwayelekile iyanothiswa esigabeni soketshezi ngaphambili kwamakristalu akhulayo, ivimbela amakristalu ukuthi angakhuli, ngaleyo ndlela kwenziwe okusanhlamvu kwacwengisiswa.

(3) Izakhi zomhlaba ezingandile zivame ukuqoqana emikhawulweni yokusanhlamvu, zinciphise ukungezwani kokuhlangana kwengxubevange, futhi zinciphise amandla okukhulisa okusanhlamvu, ngaleyo ndlela zivimbele ukukhula kwezinhlamvu ze-austenite. Ngokunjalo, i-martensite ethambile eyenziwe ngokucima nayo incane. .

Sicela ugcine umthombo nekheli lale ndatshana ukuze uphinde uprintwe: Umhlaba ongavamile ungathuthukisa ngempumelelo ubunzima bensimbi yensimbi

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.
