Ukuhlaziya Okubanzi Nengxoxo Yamajeneretha

(1) Ukulimala kwezicubu eziboshwe

Imiphumela yokuhlolwa kwe-metallographic yabonisa ukuthi kwakukhona ukuhlukaniswa kwendawo okusobala endabeni.I-Band microstructure i-microstructure eyakhiwe eduze nendawo eginqikayo yensimbi, ikakhulukazi eyakhiwe i-proeutectoid ferrite ne-pearlite.Ngenxa yokwakheka kwe-microstructure ehlukene kanye nezakhiwo zamabhendi aseduze, ukugxiliswa kwengcindezi nakanjani kuzokwenzeka phakathi kwamabhande aqinile nabuthaka, okuholela ekwehleni okuphelele kwezakhiwo zemishini kanye ne-anisotropy esobala.Ngaphansi kwesenzo samandla angaphandle, ukuklebhuka kwe-delamination kwenzeka kalula eduze kwesakhiwo se-strip, okubeka isisekelo sokungaphumeleli kokuqala kwento.

(2) Umsuka wezakhiwo ezinamabhande

Isakhiwo se-strip siyisakhiwo esivamile sesici ensimbi ephansi ye-carbon, okubangelwa izizathu ezimbili: okokuqala, i-crystallization ekhethiwe yensimbi encibilikisiwe ngesikhathi senqubo ye-crystallization ye-ingot yensimbi iholela ekusabalazweni okungalingani kwesakhiwo se-dendrite.Phakathi nenqubo yokugoqa, i-dendrite eqinile inweba futhi kancane kancane ihlangabezana nesiqondiso sokuguquguquka, ngaleyo ndlela yakhe i-superposition yamabhande aphelile futhi acebile we-carbon ne-alloy elements.Enqubweni yokupholisa kancane, i-ferrite ne-pearlite ikakhulukazi izakhiwo ezinamabhande.Kulokhu, ukuhlanganisa okubhaliwe kuyisisekelo kanye nemfuneko yokuhlanganisa izicubu.Ngakho-ke i-annealing evamile i-normalization inzima ukuqeda, kuphela ngokusebenzisa ukushisa okuphezulu kokusabalalisa i-annealing kanye nokujwayelekile kanye noma kathathu ukuze kuthuthukiswe noma kuqedwe.

Isizathu sesibili yinhlangano yeribhoni ebangelwa ubuchwepheshe obungalungile bokusebenza okushisayo.Uma izinga lokushisa elishisayo lisendaweni yezigaba ezimbili, i-ferrite idonswa kusuka ku-austenite ngamabhande ahambisana nokugeleza kwensimbi, futhi i-austenite engaboshiwe ihlukaniswa ngamabhande.Uma ipholile ku-A1, i-austenite enebhande ishintsha ibe i-pearlite enebhande.Izakhiwo ezihlanganisiwe zingathuthukiswa futhi ziqedwe ngokujwayelekile noma ukufakwa kwe-annealing.

(3) Ukuhlolwa kokulingisa kokuqeda isakhiwo esinebhande

Ukuze unqume imbangela yokuhlukaniswa kwebhande futhi uyiqede, insimbi engu-20 yayijwayelekile ngokwenqubo evamile yokwelapha ukushisa.Isakhiwo se-metallographic esiphathwayo (bheka i-FIG 6) sibonise ukuthi isakhiwo esihlanganisiwe se-scaffold sithuthukisiwe kakhulu, okubonisa ukuthi isakhiwo esihlanganisiwe se-scaffold sibangelwa inqubo yokwelashwa okungalungile kokushisa, okungathuthukiswa futhi kuqedwe ngemva kokwelashwa okufanele okujwayelekile.Ngakho-ke, imbangela yangaphakathi yokuqhekeka kwe-scaffold kanye nezinyathelo zayo zokuthuthukisa zifunwa engxenyeni ye-microstructure.

(4) Ukuhlaziya okuphelele

Kusukela ekuklanyweni nasekucutshungulweni kwesakhiwo sangaphandle sebakaki, ukuma okuphelele kwebakaki kulukhuni, i-weld iyabonakala, izimpawu zommese nemigodi zingabonakala yonke indawo, okubonisa ukuthi ikhwalithi yokucubungula iyonke ayilungile.Njengoba kungabonakala esakhiweni kanye nendawo ephukile yokwesekwa ku-FIG.1, ukuphuka kwenzeke ekhoneni lamapuleti ensimbi avundlile naqondile, ekuqaleni okwakuyisixhumanisi esibuthakathaka ekwakhiweni kwesakhiwo.Kufanele kube ne-arc transition zone yokunciphisa ukugxila kwengcindezi, kodwa kunezinyathelo ezihlukile zokuhlela.Ukungasebenzi kahle kwemishini okunjalo ngokungangabazeki kuzoholela ezindaweni zokugxilisa ingcindezi, okuzovula imigudu yokuqalwa kokuqhekeka nokuthuthuka.

Ngokuphathelene nobuchwepheshe bokucubungula jikelele bokusekela, ipuleti yensimbi eshisayo ayizange ibe yinto evamile ngaphambi kokusetshenziswa, noma ukuhlolwa kokuhlolwa ngokomzimba namakhemikhali okuhambisanayo, okuholela ekutheni izinto zokusetshenziswa ezinokukhubazeka kwesakhiwo zidluliselwe ngokuqondile kwinqubo elandelayo yokucubungula.Ngaphezu kwalokho, ipuleti lensimbi lokusekela alinqanyuliwe noma lijwayelekile ngemuva kokushisela, okuzoholela nakanjani ekubeni khona kokucindezeleka okusalayo kwe-welding futhi kusheshise inqubo yokuphuka kwe-brittle yokusekelwa ngezinga elithile.

I-Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. eyasungulwa ngo-2006, ingumkhiqizi wejeneretha kadizili eChina, ehlanganisa ukuklama, ukuhlinzeka, ukugunyazwa kanye nokugcinwa kwemishini. isethi ye-diesel generator .Ikhava yemikhiqizo Ama-Cummins , Perkins, Volvo, Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai njll. enebanga lamandla angu-20kw-3000kw, futhi babe yisikhungo sabo se-OEM yemboni nobuchwepheshe.

Ukuze uthole ukwaziswa okwengeziwe, pls xhumana no-Dingbo.
