Ukucwaninga Kwenqubo Yokuqedwa Kwensimbi Yesivinini Esiphezulu Esisheshayo

Izigayo ezigoqekayo zamanje ezibandayo ezigoqiwe sezibonile ukuzigingqa okungenakhanda nokungapheli. Izidingo zekhwalithi yemichilo, njengobubanzi besikhala nokuhluka kobukhulu bemichilo egoqwe ngamakhaza, ziya ngokuya zikhula, futhi izidingo zekhwalithi zemiqulu yomsebenzi ziya ngokuya zikhula. Ukuphakama kwentengo, kuphakama izidingo kubulukhuni bomhlaba nokujula kongqimba oluqinile. Ucwaningo olwenziwe kumaroli womsebenzi obandayo luhlale luthandwa kakhulu yimboni yama roll. Kusukela ekuqaleni kokuthwala insimbi, kuye kwathuthuka kancane kancane kwaba ngu-2% Cr, 3% Cr, no-5% Cr steel.

Ukuthuthuka kwayo kuvame ukususelwa ekwandeni okuqhubekayo kokuqukethwe kwe-chromium. Eminyakeni yamuva nje, kuvele izinto zensimbi ezinejubane eliphakeme kanye nejubane lensimbi roll roll, futhi kube khona eminye imibiko yocwaningo lwesakhiwo sayo kanye ne-carbides. Ochwepheshe beTianjin Heavy Equipment Engineering Research Co., Ltd. bafunde inqubo yokuqeda into esanda kuthuthukiswa yensimbi esheshayo eyenziwe ngesivinini esigoqiwe yomsebenzi wokugoqa umsebenzi, futhi bahlaziya imiphumela yokuqeda izinga lokushisa esakhiweni, usayizi wokusanhlamvu, kugcinwe i-austenite futhi ubulukhuni besivinini sensimbi roll. Ithonya le, lihlinzeka ngesisekelo sethiyori nesokuhlola sokuthuthukiswa kwamaroll work roll asezingeni eliphakeme.

Okusha okwenziwe ngesivinini sensimbi okusetshenzisiwe esivivinyweni bekuncibilikiswa esithandweni sokungeniswa se-50kg, kwabe sekwakhiwa ngokushisa okuphezulu kwangena okungenalutho okungu-100mm × 100mm × 250mm, okwadalulwa ngo-700 ° C ngo-4h ukuthola impahla yoqobo yokuhlola. Isampula ye-metallographic iyisikwele esingu-15mm × 15mm × 15mm, esishiswa ngomlilo omelana nebhokisi ohlobo oluthile emazingeni okushisa ahlukene futhi ucishwa ukupholisa komoya. I-660RLD / T Rockwell hardness tester isetshenziselwe ukuthola ubunzima, i-X'perPro X-ray diffractometer isetshenziselwe ukuthola i-austenite egcinwe, i-Axiovert200MAT optical microscope isetshenziselwe ukuthola ukwakheka nosayizi wokusanhlamvu, kanti i-QUANTA400 scanning electron microscope isetshenziselwe ukubona ama-carbides.

Isakhiwo se-as-cast sensimbi esetshenzisiwe esinejubane elikhulu siyi-ledeburite ephansi ye-bainite + inani elincane lama-carbides amise okwe-bar + carbides, lapho ama-carbides amakhulu amise ibha ngesikhathi sokuqina kwensimbi encibilikisiwe Ama-carbide ayisisekelo, ama-carbide ayimbudumbudu angama-carbide wesibili aqhamuka ku-austenite ngesikhathi senqubo yokupholisa, futhi okuqukethwe kwe-carbide kungu-3.6%. ucwaningo lukhombisa:

1. Ukushisa okucimayo kuthinta ukuncibilika kwe-carbides. Njengoba izinga lokushisa elicimayo likhuphuka, okuqukethwe kwe-carbide esakhiweni esicishiwe se-roll esheshayo yensimbi kuncipha kancane kancane. Lapho izinga lokushisa likhuphukela ku-1200 ℃, i-carbide eyimbudumbudu incibilikile ngokuyisisekelo
2. Isixazululo, kusele inani elincane kuphela le-carbide enkulu.
3. Njengoba izinga lokushisa licisha likhuphuka, izinhlamvu zensimbi enejubane eliphezulu ziyaqhubeka zikhula. Lapho izinga lokushisa elicisha lidlula i-1040 ° C, ukuthambekela kokukhula okusanhlamvu kusobala, izinga lokushisa lokucisha lidlula i-1160 ° C, usayizi wokusanhlamvu ufinyelela ku-4.5, futhi ukubola okusanhlamvu kubi kakhulu.
4. Njengoba izinga lokushisa licisha likhuphuka, okuqukethwe kwe-austenite egciniwe kuyaqhubeka nokwanda. Lapho izinga lokushisa licisha lingaphansi kuka-1080 ° C, okuqukethwe kwe-austenite egciniwe kukhuphuka kancane, bese okuqukethwe kwayo kukhula kakhulu. Lapho izinga lokushisa licisha lifinyelela ku-1160 ℃, okuqukethwe okugcinwe kwe-austenite kukhuphukela ku-38%. Ngakho-ke, ngokombono wokulawulwa kokuqukethwe okugcinwe kwe-austenite, izinga lokushisa elicimayo kufanele libe ngaphansi kuka-1080 ℃.
5. Lapho ucima ku-1040 ℃, ubulukhuni bufinyelela inani eliphakeme, kuze kufike ku-64.1HRC. Ngalesi sikhathi, isakhiwo sensimbi esinejubane elikhulu, usayizi wokusanhlamvu, nokuqukethwe okugcinwe kwe-austenite kufana nokuhamba phambili.
6. Izinga lokushisa elicishayo lezinto ezintsha ezihamba ngesivinini zensimbi kufanele zikhethwe phakathi kuka-1020 ～ 1080 ℃.

Sicela ugcine umthombo nekheli lale ndatshana ukuze uphinde uprintwe:Ukucwaninga Kwenqubo Yokuqedwa Kwensimbi Yesivinini Esiphezulu Esisheshayo

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. Insiza Eyengeziwe Yokulingisa Faka ukukhipha utshalomali,ukuphonsa kwesihlabathi,Ukuphonswa kwamandla, Lost Foam Ekubunjweni,I-Centrifugal Casting,Ukuphoswa Kokuqothula,Permanent Isikhunta Ukulingisa, Amakhono afaka i-EDI, usizo lobunjiniyela, ukumodeliswa okuqinile nokucutshungulwa kwesibili.

Izimboni Zokulingisa Izingxenye Zamacala Ezifundo Zezimoto: Izimoto, Amabhayisikili, Izindiza, Izinsimbi Zomculo, I-Watercraft, Amadivayisi we-Optical, Izinzwa, Amamodeli, Amadivayisi we-elekthronikhi, Ukuvaleka, Amawashi, Imishini, Izinjini, Ifenisha, Ubucwebe, AmaJig, Telecom, Ukukhanyisa, Amadivayisi Wezokwelapha, amadivayisi wezithombe, Amarobhothi, okubaziwe, okokusebenza komsindo, okwezemidlalo, i-Tooling, Amathoyizi nokuningi. 

Yini esingakusiza ukuthi uyenze ngokulandelayo?
