Intambo ene-hardfacing flux-coreIsetshenziswa kabanzi ekulungiseni nasekukhiqizeni izingxenye ezingagugi ezimayini, ekuchobozeni, ezimbonini zokugoqa insimbi kanye nezamasimende, njengezando zokuchoboza, ama-liners, ama-chute, ama-hot rolling roll kanye nama-roller okusekela i-rotary kiln. Ukusebenza kwayo kunquma ngqo impilo yesevisi yezinto zokusebenza, ngakho amakhasimende agxila kulezi zinkomba zobuchwepheshe ezilandelayo eziyinhloko.
Okokuqala, ubulukhuni ngemva kokushisela okumboziwe, okuphawulwe yi-HRC, buyisibonakaliso esibaluleke kakhulu. Amabanga obulukhuni ajwayelekile ahlanganisa i-HRC 55–58 kanye ne-HRC 60–65. Amabanga ahlukene aklanyelwe izimo zokusebenza ezahlukene: ukumelana nokuguguleka kwegumbi, ukumelana nokushisa okuphezulu kwama-rolls ashisayo, ukumelana nokushisa okuphezulu kanye nokumelana nokuguguleka okumsulwa. Kufanele kuqashelwe ukuthi amafomula entambo enziwe ngokwezifiso ngokwehlukana. Amabanga e-hammers e-crusher anomthelela ophezulu, ibanga lokugqoka okumsulwa okuluhlaza kuma-chutes nama-liners, kanye nebanga lokushisa eliphezulu lama-rolls ashisayo angasetshenziswa ngokushintshana.
Okwesibili, isakhiwo se-metallographic kanye nokwakheka kwamakhemikhali kulawulwa ngokuqinile. Okuqukethwe yi-Cr, C, Nb, Mo kanye ne-V kulungiswa ngokunembile ngokwezidingo zomklamo. Izinhlobo ezitholakalayo zifaka phakathi i-tungsten carbide composite, i-chromium cast iron ephezulu, amamaki ensimbi engagqwali ye-martensitic kanye ne-austenitic. Kumakhasimende ezimayini zaphesheya kwezilwandle kanye ne-metallurgical, isitifiketi sokuhlola izinto (i-MTC) singanikezwa uma siceliwe ukuqinisekisa ukwakheka kwamakhemikhali.
Ukuzwela kwemifantu kungenye into ekhathazayo, ikakhulukazi ezintweni zokusebenza ezinkulu njengemiqulu esindayo yokugoqa kanye nezinsimbi ezijiyile. Abathengi bazohlola ukuthi ungqimba olungaphezulu luvame ukuqhekeka yini, ukuthi ngabe ukushisela okungaphezulu kwezingqimba eziningi kungenzeka yini, nokuthi ingabe ukufudumala kwangaphambilini kanye nokugcinwa kokushisa ngemva kokushisela kuyadingeka yini ngesikhathi senqubo yokushisela. Ukumelana nemifantu okungenangqondo kuzoholela ekuqhekekeni kusenesikhathi kanye nokwehluleka kongqimba oluqinile.
Amakhasimende futhi anaka kakhulu impilo yokusebenza yokugqoka. Ngokuvamile aqhathanisa impilo yokusebenza nemikhiqizo evela kwabanye abahlinzeki. Idatha yokusetshenziswa kwensimu kanye namakesi okusebenza angempela kuma-crusher, ama-rolling roll kanye nama-roller support rollers ajikelezayo kuyizinkomba ezibalulekile zokuhlola kwawo.
Ngaphezu kwalokho, ukusetshenziswa kahle kokushisela akunakunganakwa. Amaphuzu abalulekile afaka phakathi izinga lokufafaza, ukususwa kwe-slag kanye nokwakheka kobuhlalu bokushisela. Iningi lezimboni zensimbi kanye nezezimayini zisebenzisa imishini yokushisela okuzenzakalelayo, njengemishini yokushisela evulekile kanye nemishini yokushisela engaphansi komhlaba. Ukuhambisana okuhle nezinhlelo zokushisela okuzenzakalelayo kuqinisekisa ukondla okuzinzile, ikhwalithi yokushisela eqhubekayo kanye nokusebenza kahle kokukhiqiza okuphezulu.
