Ucingo olune-core ye-Hardfacing fluxIsetyenziswa kakhulu ekulungiseni nasekwenzeni iindawo ezingagugiyo kwimigodi, ukutyumza, ukuqengqeleka kwentsimbi kunye nemizi-mveliso yesamente, njengee-crusher hammers, ii-liners, ii-chutes, ii-hot rolling rolls kunye nee-rotary kiln support rollers. Ukusebenza kwayo kumisela ngokuthe ngqo ubomi benkonzo yezinto zokusebenza, ngoko ke abathengi bagxila kwezi mpawu zobugcisa zilandelayo.
Okokuqala, ubunzima emva kokuwelda ngaphezulu, okuphawulwe yi-HRC, lolona phawu lubalulekileyo. Amanqanaba obunzima aqhelekileyo agubungela i-HRC 55–58 kunye ne-HRC 60–65. Amanqanaba ahlukeneyo aphuhliswa kwiimeko ezahlukeneyo zokusebenza: ukumelana nokukrala kwegumbi, ukumelana nobushushu obuphezulu kwiiroli eziqengqelekayo ezishushu, ukumelana nobushushu obuphezulu kunye nokumelana nokukrala okucocekileyo. Kufuneka kuqatshelwe ukuba iifomyula zentambo zenziwe ngokwezifiso ngokwahlukeneyo. Amanqanaba eehammer ze-crusher ezinempembelelo ephezulu, amanqanaba okukrala okucocekileyo kwiichutes nakwii-liners, kunye namanqanaba obushushu obuphezulu kwiiroli eziqengqelekayo ezishushu azinakusetyenziswa ngokutshintshana.
Okwesibini, ulwakhiwo lwe-metallographic kunye nolwakhiwo lweekhemikhali lulawulwa ngokungqongqo. Okuqulathwe yi-Cr, C, Nb, Mo kunye ne-V kulungelelaniswa ngokuchanekileyo ngokweemfuno zoyilo. Iintlobo ezikhoyo ziquka i-tungsten carbide composite, i-chromium cast iron ephezulu, i-martensitic kunye ne-austenitic stainless steel grades. Kubathengi bemigodi baphesheya kunye nabathengi be-metallurgical, isatifikethi sovavanyo lwezinto (MTC) sinokubonelelwa xa siceliwe ukuqinisekisa ulwakhiwo lweekhemikhali.
Ubuthathaka beentanda zentsimbi yenye ingxaki enkulu, ingakumbi kwiindawo zokusebenza ezinkulu ezifana neeroli eziqengqelekayo ezinzima kunye nee-castings ezixineneyo. Abathengi baya kujonga ukuba umaleko womphezulu uthambekele ekuqhekekeni, ukuba i-multi-layer overlay welding inokwenzeka na, kwaye ukuba ukufudumala kwangaphambili kunye nokugcinwa kobushushu emva kokuwelda kuyadingeka na ngexesha lenkqubo yokuwelda. Ukumelana neentanda okungafanelekanga kuya kukhokelela ekuqhekekeni kwangethuba kunye nokungaphumeleli komaleko wobuso obuqinileyo.
Abathengi banika ingqalelo engakumbi kubomi benkonzo yokunxiba. Badla ngokuthelekisa ubomi bokusebenza neemveliso ezivela kwabanye abathengisi. Idatha yokusetyenziswa kwentsimi kunye neekheyisi zokwenyani zokusebenza kwii-crushers, ii-rolling rolls kunye nee-rotary kiln support rollers zizinto ezibalulekileyo ekuvavanyweni kwazo.
Ukongeza, ukusetyenziswa kakuhle kwe-welding akunakutyeshelwa. Amanqaku aphambili aquka inqanaba lokutshiza, ukususwa kwe-slag kunye nokwenziwa kweentsimbi ze-weld. Uninzi lweefektri zesinyithi kunye nezemigodi zisebenzisa izixhobo zokugquma ngokuzenzekelayo, ezinje ngee-arc ezivulekileyo kunye nee-submerged-arc surfacing machines. Ukuhambelana okuhle neenkqubo zokugquma ngokuzenzekelayo kuqinisekisa ukondla okuzinzileyo, umgangatho wokugquma ohambelanayo kunye nokusebenza kakuhle kwemveliso.
