induction Ukushisa ukucindezela ukukhulula

Ukunciphisa Ukucindezeleka Kokungeniswa Ngensimbi esetshenziselwe ukubanda, yakhiwa, yafakwa ngomshini, yashiselwa noma yasikwa, kungadingeka ukuthi kwenziwe umsebenzi wokuqeda ukucindezeleka ukunciphisa izingcindezi ezenziwe ngesikhathi senqubo yokuqamba.

Induction Heating Stress ukukhulula isetshenziswa kuzo zombili izingxube ze-ayoni nezingenayo futhi kuhloselwe ukususa izingcindezi zangaphakathi eziyinsalela ezenziwa yizinqubo zangaphambilini zokukhiqiza ezifana nemishini, ukugoqa okubandayo nokushisela. Ngaphandle kwakho, ukucubungula okulandelayo kungadala ukuphazamiseka okungamukeleki kanye / noma okokusebenza kungabhekana nezinkinga zesevisi njengokuqhekeka kokugqwala kwengcindezi. T ukwelashwa akuhloselwe ukukhiqiza ushintsho olukhulu kuzinto ezibonakalayo noma izakhiwo zemishini, ngakho-ke kuvame ukukhawulelwa emazingeni okushisa aphansi kakhulu.

Ngensimbi esetshenziselwe ukubanda, yakhiwa, yafakwa ngomshini, yashiselwa noma yasikwa, kungadingeka ukuthi kwenziwe umsebenzi wokuqeda ukucindezeleka ukunciphisa izingcindezi ezenziwe ngesikhathi senqubo yokuqamba.

Izingcindezi zensimbi ngenxa yomsebenzi wokwenza izinto zingadala ushintsho lobukhulu obungafuneki, ukuhlanekezela, ukwehluleka ngaphambi kwesikhathi noma ukuqhekeka kwengcindezi kwengxenye lapho kukhishwa lezi zingcindezi. Izingxenye ezinezidingo eziqinile zobukhulu zingadinga ukukhululeka kwengcindezi ngaphambi kokuba kwenziwe eminye imisebenzi yokukhiqiza. Izingxenye ezishiselwe zingenziwa zingabi nazimpikiswano ngomsebenzi wokushisa wokuqeda ukucindezeleka.

Ukucindezelwa Kwe-Induction kukhulula ingenziwa egumbini lomoya elilawulwayo noma i-vacuum ukunciphisa i-oxidation.

Izinsimbi zecarbon nezinsimbi ze-alloy zinganikezwa ngezindlela ezimbili zokukhululeka kwengcindezi:
1. Ukwelashwa ngokujwayelekile okungu-150-200 ° C kudambisa izingcindezi eziphakeme ngemuva kokuqina ngaphandle kokunciphisa kakhulu ubulukhuni (isb. Izingxenye eziqinile, amabhere, njll.):
2. Ukwelashwa ngokujwayelekile okungu-600-680 ° C (isb. Ngemuva kokushisela, ukusebenzisa imishini njll.) Kunikeza ukukhululeka kokucindezeleka okuphelele.

Ama-alloys angenayo ingcindezi ancishiswe emazingeni okushisa ahlukahlukene ahlobene nohlobo lwengxubevange nesimo. Ama-alloys asebenze kanzima eminyakeni yobudala anqunyelwe ekucindezelekeni ekudambiseni amazinga okushisa angaphansi kwezinga lokushisa eligugile.
Izinsimbi ezingenasici zase-Austenitic zikhululeka ngaphansi kwengu-480 ° C noma ngaphezulu kuka-900 ° C, amazinga okushisa aphakathi kokunciphisa ukumelana nokugqwala emabangeni angaqinisiwe noma anekhabhoni ephansi. Ukwelashwa okungaphezu kuka-900 ° C kuvame ukuba izixazululo ezigcwele zezixazululo.

Ukwenza okujwayelekile kusetshenziswe kwabanye, kepha hhayi bonke, izinsimbi zobunjiniyela, ukwenza okujwayelekile kungathambisa, kuqinise noma kucindezele ukukhulula into, kuya ngesimo sayo sokuqala. Inhloso yokwelashwa ukuphikisana nemiphumela yezinqubo zangaphambilini, njengokuphonsa, ukufaka noma ukugingqa, ngokucwenga isakhiwo esingeyona iyunifomu sibe esithuthukisa ukusetshenzwa / ukuhleleka noma, kumafomu athile womkhiqizo, ahlangabezana nezidingo zokugcina zomkhiqizo.

Inhloso enkulu ukulungisa insimbi ukuze kuthi, ngemuva kokubunjwa okwalandela, into ethile iphendule ngokugculisayo ekusebenzeni kokuqina (isb. Ukwenza okujwayelekile kuqukethe ukushisa insimbi efanelekile ekushiseni okujwayelekile ku-830-950 ° C (phezulu noma ngaphezulu kwezinga lokushisa eliqinile lezinsimbi ezenza lukhuni, noma ngaphezulu kwezinga lokushisa le-carburising lezinsimbi zokubamba) bese lipholisa emoyeni. Ukushisa kuvame ukwenziwa emoyeni, ngakho-ke imishini elandelayo noma ukuqeda indawo kuyadingeka ukususa izingqimba zesikali noma ze-decarburised.

Izinsimbi ezenza umoya uqine (isb. Ezinye izinsimbi zamagiya ezimoto) zivamise “ukufuthelana” (ngokuncishiselwa ngokweqile) ngemuva kokujwayela ukuthambisa isakhiwo kanye / noma ukukhuthaza ukusebenza ngamandla. Ukucaciswa okuningi kwezindiza kudinga futhi le nhlanganisela yokwelashwa. Izinsimbi ezingajwayelekile ukwenziwa yilezo eziba lukhuni kakhulu ngesikhathi sokupholisa umoya (isb. Izinsimbi eziningi zamathuluzi), noma lezo ezingatholi nzuzo yesakhiwo noma ezikhiqiza izakhiwo ezingafanelekile noma izakhiwo zemishini (isb. Insimbi engagqwali).

Induction ukushisa umshini we-PWHT isetshenziselwa kabanzi ipayipi / ithubhu weld peheat ne-pwht, ukucindezela ukukhumbula nokunye.

Ukushisela kungenye yezinqubo ezibucayi kakhulu ekwenziweni kwemikhumbi yengcindezi njenge-boiler yesikhungo samandla esishisayo. Izinga lokushisa ledamu le-weld elincibilikisiwe ngesikhathi senqubo lisendaweni ka-2000 deg C. Ukwanda kokushisa kuyashesha futhi kusenjalo. Lapho lesi siqeshana sedamu elincibilikisiwe siphola phansi ukuncipha kuholela ekucindezelekeni okushisayo okuvaleleke ngaphakathi kwensimbi. Lokhu futhi kungashintsha ukwakheka kwensimbi.

I-PWHT isusa le miphumela ngokufudumeza, ukumanzisa, nokupholisa indawo ye-weld ngendlela elawulwayo kuya emazingeni okushisa angaphansi kwephoyinti lokuqala loguquko, okunika isakhiwo semakhro isikhathi esanele sokulungisa isimo saso sokuqala nokususa ukucindezela okusele.

I-PWHT iqukethe ukufudumeza insimbi ngemuva kwenqubo yokushisela ngendlela elawulwayo kuya ekushiseni okungaphansi kwephoyinti lokuqala loguquko, kumanziswa kulelo zinga lokushisa isikhathi esanele ngokwanele, nokupholisa ngamanani alawulwayo.

Ukushisa ukushisa kuyindlela eyodwa ethola ukuthandwa yize izindleko ziphakeme. Le nqubo enobungani be-welder. Ngokungafani nokumelana nokushisa ipayipi kuphela elishisayo. Ama-gradients okushisa ayalingana kuwo wonke ubukhulu.

Amandla okushisa avela ku-10KW ~ 120KW

Imodeli: 10KW, 20KW, 40KW, 60KW, 80KW, 120KW njalonjalo.

Ukushisa okushisayo: 0 ~ 900 C

Izinga lokushisa lokushisa okukhulu: 900 C

Ipayipi / ububanzi bepayipi: 50 ~ 2000 mm

Ikhoyili yokushisa: Ikhoyili yocingo noma ingubo yokushisa yokungeniswa

Umshini we-induction weld preheating umshini ufaka:
