Ukuqhathaniswa kwe-High-Speed ​​Steel kanye ne-Cemented Carbide Materials

Insimbi enesivinini esikhulu (i-HSS) kanye ne-carbide enosimende yizinto ezimbili ezisetshenziswa kakhulu ezimbonini ezahlukahlukene, ikakhulukazi kumathuluzi okusika nokusetshenziswa kwemishini. Zombili izinto ezisetshenziswayo zibonisa izakhiwo ezihlukile ezizenza zifanelekele izinjongo ezithile. Kulesi sihloko, sizoqhathanisa futhi siqhathanise izici zensimbi enesivinini esikhulu kanye ne-carbide enosimende, sigxile ekubunjweni kwabo, ukuqina, ukuqina, ukumelana nokugqoka, nokusebenza okuphelele.

Ukwakhiwa:

High-Speed ​​Steel: High-speed steel iyingxubevange eyakhiwe ngokuyinhloko iron, carbon, cobalt, tungsten, molybdenum, futhi vanadium. Lezi zakhi ze-alloying zithuthukisa ubulukhuni bento, ukumelana nokuguga, namandla ezinga lokushisa eliphezulu.

I-Cemented Carbide: I-carbide enosimende, eyaziwa nangokuthi i-tungsten carbide, iqukethe isigaba se-carbide esiqinile (imvamisa i-tungsten carbide) efakwe ensimbi ehlanganisayo njenge-cobalt noma i-nickel. Le nhlanganisela ihlinzeka ngezinto ezinobunzima obungavamile kanye nokumelana nokugqoka.

Ukuqina:

I-High-Speed ​​Steel: I-HSS ngokuvamile inobunzima obusuka ku-55 kuya ku-70 HRC (isikali se-Rockwell C). Leli zinga lobulukhuni livumela amathuluzi e-HSS ukuthi anqamule ngempumelelo inhlobonhlobo yezinto zokwakha, okuhlanganisa insimbi, insimbi engagqwali, nensimbi yokusansimbi.

I-Cemented Carbide: I-carbide enosimende idume ngobulukhuni bayo obedlulele, imvamisa ifinyelela ku-80 kuya ku-95 HRA (isikali se-Rockwell A). Ukuqina okuphezulu kwenza amathuluzi e-carbide enosimende alungele ukwenza izinto eziqinile ezifana nama-titanium alloys, izinsimbi eziqinile, nezinhlanganisela.

Ukuqina:

I-High-Speed ​​Steel: I-HSS ibonisa ukuqina okuhle futhi ingamelana nomthelela omkhulu kanye nemithwalo yokushaqeka, iyenze ifanelekele ukusika okuphazamisekile nokusebenza komshini osindayo. Ukuqina kwayo futhi kusiza ukugaywa kabusha kanye nokwakheka kabusha kwamathuluzi.

I-Cemented Carbide: Nakuba i-carbide enosimende inzima kakhulu, i-brittle uma iqhathaniswa ne-HSS. Ingase ihlehle noma iphuke ngaphansi komthelela osindayo noma imithwalo yokushaqeka. Kodwa-ke, amamaki esimanje e-carbide ahlanganisa ukuqina okuthuthukisiwe futhi angamelana nemithelela emaphakathi kuya kokukhanya.

I-Wear Resistance:

I-High-Speed ​​Steel: I-HSS inokumelana okuhle nokugqokwa, ikakhulukazi uma isetshenziswa ngesivinini esiphansi sokusika. Kodwa-ke, ngesivinini esikhulu sokusika noma lapho kwenziwa izinto ezinokuqina okuphezulu, ukumelana nokugqokwa kwe-HSS kungenzeka kunganele.

I-Cemented Carbide: I-carbide enosimende idume ngokumelana nokugqokwa kwayo okukhethekile ngisho nasezimeni zemishini eziyinselele. Isigaba se-carbide esiqinile sinikeza ukumelana okuphakeme ekugqokeni kwe-abrasive, okuvumela amathuluzi e-carbide ukuthi agcine umkhawulo wawo wokusika isikhathi eside.

Ukusebenza:

I-High-Speed ​​Steel: Amathuluzi e-HSS ahamba phambili ezinhlelweni eziningi zokusika ngenxa yokuguquguquka kwawo, ukuqina, kanye nokulula okuhlobene kokulola. Afanele ukusebenza kwemishini yenhloso evamile futhi angabizi kakhulu uma kuqhathaniswa ne-carbide esimende.

I-Cemented Carbide: Amathuluzi e-carbide enosimende asetshenziswa kabanzi ukwenza ukunemba okuphezulu nokusebenza kahle kwemishini. Zisebenza kahle kakhulu ekufuneni izicelo ezinesivinini esikhulu sokusika, impilo yamathuluzi enwetshiwe, kanye nokukhiqiza okukhuphukile. Nokho, ngokuvamile zibiza kakhulu kunamathuluzi e-HSS.

Isiphetho:

Insimbi enesivinini esiphezulu kanye ne-carbide enosimende kokubili kuyizinto ezibalulekile embonini yamathuluzi okusika, ngayinye inamandla ayo kanye nokulinganiselwa kwayo. Insimbi enesivinini esikhulu ihlinzeka ngokuqina okuhle, ukuguquguquka, kanye nokusebenza kahle kwezindleko, iyenze ifaneleke uhla olubanzi lwezinhlelo zokusebenza zemishini. Ngakolunye uhlangothi, i-carbide enosimende ihamba phambili ngobulukhuni, ukumelana nokugqoka, kanye nokuzinza kwezinga lokushisa eliphezulu, okwenza kube ukukhetha okuthandwayo komshini wezinsimbi eziqinile nezinye izinto eziyinselele.

Ukuqonda izidingo ezithile zomsebenzi womshini kanye nezinto zokusebenza kubalulekile ekukhetheni izinto ezifanele. Izinto ezifana nesivinini sokusika, ubulukhuni bezinto ezibonakalayo, nokuphila kwamathuluzi afiselekayo kumelwe kucatshangelwe ngokucophelela. Ekugcineni, ukukhetha phakathi kwensimbi enesivinini esiphezulu kanye ne-carbide enosimende kuzoxhomeka kuhlelo lokusebenza oluthile kanye nemiphumela oyifunayo.
