Iyini i-Induction Hardening?

Izimiso Ezisemuva Kokuqina Kokungeniswa

Induction ye-electromagnetic

Ukuqeda ukuqina kuyinqubo yokwelapha ukushisa eyenza ngokukhetha lukhuni ingaphezulu lezingxenye zensimbi ngokusebenzisa izimiso zokungeniswa kwe-electromagnetic. Le nqubo ihlanganisa ukudlulisa igagasi elishintshashintshayo lemvamisa ephezulu ngekhoyili yokungeniswa ebekwe eduze kwengxenye, okukhiqiza inkambu enamandla kazibuthe kagesi. Njengoba inkambu ye-electromagnetic ixhumana nezinto ezihambisayo, idonsa imisinga kagesi ngaphakathi kwengxenye, okubangela ukushisa okusheshayo nokwasendaweni kwendawo.

Ukushisisa Ngokushesha kanye Nokucisha

Imisinga ebangwayo idala ukushisa ngaphakathi kwendawo, ikhuphule izinga lokushisa layo kububanzi be-austenitic (imvamisa ephakathi kuka-800°C no-950°C ngensimbi). Uma izinga lokushisa elifunekayo selifinyelelwe, ingxenye icinywa ngokushesha, ngokuvamile ngokuyifafaza noma ngokuyicwilisa endaweni yokucisha, njengamanzi, uwoyela, noma isixazululo se-polymer. Ukupholisa okusheshayo kubangela ukuthi i-austenite iguquke ibe i-martensite, i-microstructure eqinile futhi engagugi, okuholela ekubeni ungqimba lwangaphezulu oluqinile.

Izinzuzo ze-Induction Harding

Ukuqina Kobuso Okwengeziwe kanye Nokumelana Nokugqoka

Enye yezinzuzo eziyinhloko zokuqina kwe-induction yikhono lokuthola ubulukhuni obukhethekile bomhlaba kanye nokumelana nokugqoka. I-martensitic microstructure eyakhiwe phakathi nenqubo yokucisha ingase ibangele amanani obulukhuni obungaphezulu obungaphezu kuka-60 HRC (Rockwell Hardness Scale C). Lobu bunzima obuphakeme buhumusheka ekuqineni kokuguga, okwenza izingxenye eziqinile zokungeniswa zilungele izinhlelo zokusebenza ezibandakanya ukuslayida, ukugingqika, noma imithwalo enomthelela.

Ukuqina Okunembile Nokwasendaweni

Ukuqina kokungeniswa kuvumela ukuqina okunembayo nokwasendaweni kwezindawo ezithile engxenyeni. Ngokuklama ngokucophelela ikhoyili ye-induction kanye nokulawula iphethini yokufudumeza, abakhiqizi bangakwazi ukukhetha izindawo ezibucayi ngenkathi beshiya ezinye izindawo zingathinteki. Leli khono libaluleke kakhulu ezinhlelweni zokusebenza lapho izingxenye ezithile kuphela zengxenye zidinga ubulukhuni obuthuthukisiwe nokumelana nokungagugi, njengamazinyo egiya, ama-cam lobes, noma izindawo ezithwalayo.

Energy Efficiency

Uma kuqhathaniswa nezinye izinqubo zokwelashwa kokushisa, ukuqina kokungeniswa konga amandla kakhulu. Ikhoyili yokungeniswa ishisa ngokuqondile ingaphezulu lengxenye, inciphisa ukulahlekelwa kwamandla okuhlobene nokushisisa yonke ingxenye noma isithando somlilo. Ukwengeza, imijikelezo esheshayo yokushisisa nokupholisa inomthelela ekongeni amandla, okwenza ukuqina kokungeniswa kube yinqubo evumelana nemvelo futhi engabizi kakhulu.

Ukuguquguquka nokuguquguquka

Ukuqina kwe-induction kuyinqubo eguquguqukayo engasetshenziswa ezintweni eziningi ezahlukahlukene, kufaka phakathi amamaki ahlukahlukene ensimbi, insimbi ecijile, kanye nama-alloys athile angeyona ayoni. Ibuye ifanele izingxenye zomumo nobukhulu obuhlukene, kusukela kumagiya amancane nama-bearings kuya kuma-shaft amakhulu namasilinda. Ukuvumelana nezimo kwe ukuqina kokungeniswa ivumela abakhiqizi ukuthi bahlele amapharamitha wenqubo ukuze ahlangabezane nezidingo ezithile, aqinisekise ubulukhuni obufanele kanye nokusebenza.

Izicelo ze-Induction Harding

Industry Automotive
