Ungalithuthukisa kanjani kakhulu ikhwalithi lokuthwala insimbi ngokupholisa okusheshayo okukhulu ngemuva kokugoqa

Amabhere ayingxenye ebalulekile yemishini yemishini. Ngokwezinga elithile, ikhwalithi yamabheringi ivimbela ijubane nenqubekela phambili yomnotho wezwe, ukwakhiwa kwezokuvikela kuzwelonke kanye nokwenziwa kwesimanje kwezesayensi nezobuchwepheshe, kanye nenqubekela phambili yokuthwala ubuchwepheshe bokukhiqiza insimbi ithinta ngqo imboni ethwele Ukuthuthuka, amazwe athuthukile kwezimboni ahlanganisa kakhulu ocwaningweni ngekhwalithi yokuthwala imikhiqizo yensimbi.

Ukwenza ngcono ikhwalithi yokuthwala insimbi nokuqinisekisa ukuthi inamandla amakhulu okukhathala, amandla acindezelayo, ubulukhuni bomhlaba nempilo enhle yenkonzo, kuyadingeka ukuthuthukisa ubumsulwa bensimbi nokufana kwama-carbides ensimbi, ikakhulukazi okufakiwe impahla. Okuqukethwe, uhlobo lokufakwa nokuqukethwe kwegesi; nokufana kokuma, usayizi nokusatshalaliswa kwama-carbide kungenye inkomba ebalulekile yokukala ikhwalithi yokuthwala imikhiqizo yensimbi.

Ngesikhathi senqubo yokupholisa ngemuva kokugoqa okushisayo, ama-carbide wesibili akhiwe anomthelela obalulekile ekusebenzeni kwensimbi ethwele. Ngakho-ke, kuyadingeka ukuthi i-carbide yenethiwekhi ensimbi ethwele kufanele ibe ngaphansi kuka-2.5. Inqwaba ye-carbide yenethiwekhi izoletha imiphumela emibi:

• Ekucimeni okulandelayo komkhiqizo ophelile, awunakususwa ngokuphelele.
• Ama-carbides anjenge-net agcinwe ensimbi ethwele kakhulu akhulisa kakhulu ukuqina kwezingxenye futhi anciphise amandla okumelana nemithwalo yomthelela.
• Ngaphansi kwesenzo somthwalo oshukumisayo, izingxenye zilula ukwephula umngcele wokusanhlamvu.
• Khulisa ukuthambekela kokucima ukuqhekeka.

Njengamanje, izwe lami ikakhulukazi lisebenzisa inqubo yokugingqika okushisa okuphansi ukulawula imvula yokuthwala ama-carbide wensimbi, bese igcwalisa ngezinga elithile lokupholisa. Kodwa-ke, le nqubo incike emthonjeni wokugaya futhi idinga umthamo owanele wokupholisa ngaphambi kokuqeda ukugoqa. Ngemuva kokupholisa amanzi, kunesikhala esanele se-isothermal ngaphambi kokugoqa kokugcina. Emgqeni wokukhiqiza oqhubekayo, ukugoqa okushisa okuphansi kuyabonakala. Ngenxa yokungabi namandla okupholisa okwanele kwemishini ekhona yokupholisa, izinga lokushisa kunzima ukulilawula ngokunembile, ikakhulukazi imigoqo yosayizi omkhulu ngenhla kuka-Ф30mm, ikhwalithi yomkhiqizo ayizinzile, nemvula yenethiwekhi ye-carbide inzima.

Ukuze kuthuthukiswe ikhwalithi yomkhiqizo wezincazelo ezahlukahlukene zensimbi ethwala izinsimbi kanye nokunciphisa ukuthembela okukhulu ekusetshenzisweni kwezigayo nezinye izinto ekukhiqizeni insimbi ethwele, i-State Key Laboratory yeRolling Technology ne-Continuous Rolling Automation (RAL) yaseNyakatho-mpumalanga yeYunivesithi ngaphandle kobuchwepheshe be-ultra-fast bokupholisa bokuthwala imigoqo yensimbi. Umsebenzi wokucwaninga wenziwe ezimeni zezulu zama-carbides kanye noshintsho lwesigaba ngesikhathi sokupholisa okuqhubekayo.

Ubulukhuni obuncane besakhiwo sensimbi esithwalayo kanye nesikhala se-pearlite lamella kuthinteka ngezinga lokupholisa ngemuva kokugingqika. Njengoba izinga lokuphola lenyuka ngemuva kokugingqika okushisayo, isikhala se-pearlite lamella siyancipha ngenkathi inani le-microhardness lenyuka, futhi isikhala esincane se-lamella sizuzisa kakhulu ekunciphiseni okulandelayo kwe-spheroidizing.

Umgomo wokulawula ukuthi ngesikhathi senqubo yokupholisa eqhubekayo ye-austenite engaphansi, i-austenite izovela ngokungenakugwenywa endaweni engabi nakhabhoni nasendaweni ecebile ngekhabhoni. Lapho nje izimo ze-nucleation sezihlangatsheziwe, kuyilapho i-ferrite yakhiwa endaweni engenawo umoya ongcolile, i-cementite nayo iyakhiwa endaweni ecebile nge-carbon. Lezi zombili zivumelanisiwe ngasikhathi sinye, i-eutectoid ne-symbiosis, zakha i-pearlite nucleus (i-ferrite + Cementite), futhi ngasikhathi sinye i-crystal nuclei entsha ikhiqizwa kwezinye izingxenye futhi ikhula ngokuqhubekayo. Lapho kwakhiwa i-pearlite, ukukhula kwe-longitudinal kusho ukuthi amashidi we-cementite nama-ferrite aqhubeka ngokuqhubekayo abe yi-austenite ngasikhathi sinye, ngenkathi ukukhula kwe-lateral kusho ukuthi amashidi e-cementite nama-ferrite ahlanganiswa ngokunye ukuze akhule.

Ukukhuphula izinga lokupholisa eliqhubekayo ngemuva kokukhubazeka kuzodlala indima ekuhlanzeni izinhlamvu zama-austenite. Usayizi wezinhlamvu ze-austenite awunawo umthelela osobala esikhaleni se-pearlite lamella, kepha uthinta ubukhulu bama-pearlite pellets. Izinhlamvu ze-austenite zilungile futhi indawo yomngcele wokusanhlamvu ngeyunithi ngayinye iyakhuphuka, okuzothuthukisa i-pearlite. Uma inani lezindawo ze-nucleation ze-pearlite landa, ubukhulu bamapeleti we-pearlite ancipha.

Ubuchwepheshe bokupholisa obushesha kakhulu busetshenziswa ekulawuleni i-carbide yensimbi ethwele, ukuze insimbi ethwele idlule ngokushesha endaweni lapho imvula ye-carbide inamandla ngemuva kokugingqika, enganciphisa kakhulu noma igweme imvula yama-carbide wesibili eceleni komngcele wokusanhlamvu.

Indlela yesici esilinganiselwe isetshenziselwa ukulingisa nokuhlaziya inkambu yokushisa yenqubo yokupholisa eshesha kakhulu yokuthwala insimbi yokucaciswa okuhlukile ngemuva kokugingqika, futhi kunqunywa indlela yokupholisa enengqondo. Ngalesi sizathu, idivayisi yokupholisa esheshayo yokuthwala imigoqo yensimbi kanye nohlelo lokulawula oluhlobene.

Ngokuya ngezidingo zenqubo yokupholisa esheshayo, ehlanganiswe nezimo zangempela zokukhiqiza, imishini yokupholisa ehlangabezana nezidingo zenqubo yokupholisa eshesha kakhulu yokuthwala insimbi ngemuva kokugoqeka yaklanywa, futhi uhlelo lokulawula oluzenzakalelayo lwakhiwa, kanye nesibalo esiphelele imodeli yasungulwa ukwenza ukunemba kokushisa kokushisa kwensimbi ethwele ne-Coolingityity kuye kwathuthukiswa kakhulu

Imininingwane yensimbi ethwala eyenziwe ngobuchwepheshe bokupholisa obushesha kakhulu yi-Ф15.3mm ~ Ф60mm. Izinga leziqu lokuthwala ama-carbides wensimbi angama-mm30mm noma ngaphansi kanti iklasi elingu-2.0 noma ngaphansi lenyusiwe lisuka ku-10% laya ku-100%; for Ф30mm ~ Ф60mm eziveza steel anezikhala carbides, liye lenyuka lisuka 2.5 ~ 4 kuya 2.0. Izinga lokuphasa elilandelayo lingaphezu kuka-95%. Ngensimbi ethwele engu- Ф60mm ~ Ф120mm, ukuklwebheka ebusweni ngemuva kokupholisa okushesha kakhulu kuthuthukiswe kakhulu.

Sicela ugcine umthombo nekheli lale ndatshana ukuze uphinde uprintwe:Ungalithuthukisa kanjani kakhulu ikhwalithi lokuthwala insimbi ngokupholisa okusheshayo okukhulu ngemuva kokugoqa

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.
