a.Izinto:
Isando esisicaba senziwe ngealloyi ephezulu yechromium, enokumelana okuqinileyo kunye nokuqina okuhle, kwaye inokumelana nobushushu obuphezulu kunye nokuxhathisa ukubola.Ngobomi obude benkonzo, ukugcinwa okulula kunye nokukwazi ukutyumza izinto ezinkulu kunye ezinzima, isando esicaba siyakwazi ukulungelelanisa kwizinto ezahlukeneyo.
b.Inkqubo yokwenziwa ekwinqanaba eliphezulu:
● Uyilo olwenziwe ngokwezifiso: I-teknoloji yangaphandle yokucoca i-furnace kabini ngokufanelekileyo iyanciphisa umonakalo wezinto ezinobungozi, ukufakwa kunye ne-oksijini kunye ne-hydrogen, kwaye iphucula kakhulu ukuxhathisa ukunxiba kunye nefuthe lokuqina kwentsimbi;Ubungakanani obufanelekileyo kunye noyilo lwesakhiwo, ukuchaneka okuphezulu kokuphosa, ukufakela okufanelekileyo kunye nokuthembeka okuphezulu.
● Inkqubo yokuvelisa: Unyango lwe-Metamorphic, ukulungiswa kweenkozo, ukuphucula i-morphology kunye nokusabalalisa i-carbide, kunye nokuphucula ngakumbi ukuxhathisa ukunxiba kunye nokuqina okuqinileyo kwesando esicaba;
● Ukulawulwa komgangatho: Lungiselela inkqubo yonyango lobushushu, ukwenzela ukuba ukuqina kwesando esisicaba kufane, kwaye ukunyanzeliswa kwempembelelo yokunxiba kunamandla.
c.Ukuhlolwa okungqongqo:
● Ukufunyaniswa kwempazamo kufuneka kwenziwe kwimveliso nganye ukuqinisekisa ukuba akukho mingxunya yomoya, imingxuma yesanti, i-slag inclusions, ii-cracks, deformation kunye nezinye iziphene zokuvelisa.
● Ibhetshi nganye yehamile eyisicaba ihlolwa ngokungenamkhethe phambi kokunikezelwa, kubandakanywa novavanyo lwemathiriyeli kunye neemvavanyo zokusebenza komzimba ukuqinisekisa ukusebenza okusebenzayo kunye nokubonelela ngamaphepha ovavanyo lwebhubhoratri.
Ukuqina ukuya kuthi ga kwi-60HRC-65HRC, iseti ukuxhathisa kwe-abrasion, ukumelana nobushushu obuphezulu be-oksijini, ukuxhathisa ukudinwa kwe-thermal, ukumelana nokugqwala, ukuxhathisa ukunxiba kunye nokuchasana nempembelelo kwenye.
Isetyenziswa ngokubanzi kwisityumzi sempembelelo kwimigodi, i-samente, isinyithi, imichiza, iziseko zophuhliso kunye namanye amashishini.
