Okokuqala, umahluko kwinkqubo yemveliso:
(1) Inkqubo yokuvelisa ibhola yentsimbi yokusila (ibhola yentsimbi engatyiwayo, ibhola yentsimbi ethweleyo, ibhola yentsimbi enekhabhoni eninzi, ibhola yentsimbi yekhabhoni):
Izinto eziluhlaza (intonga yocingo, intsimbi engqukuva) – umzobo wocingo oluya kwintambo – intloko ebandayo/ukubumba – ibhola (ukupolisha) – unyango lobushushu – ukuphuculwa kokugaywa okuqinileyo – - – uphando – ekuqaleni kokufunyanwa kweziphene emehlweni – ukuleqa – ukucoca – ukuhlolwa – ukupakisha
(2) inkqubo yokuvelisa ibhola yentsimbi yokubumba: izinto eziluhlaza ezijikelezileyo zokusika intsimbi Icandelo le-engile – - – - ukuqengqeleka kwebhola ukufudumeza/ukuhlolwa kokubumba ibhola — – – – – – ukucima ukupholisa – ukupholisa – ukupakisha
(3) inkqubo yokuvelisa ibhola yentsimbi ephosiweyo: umlinganiselo wezinto ezikrwada – izixhobo – ukunyibilikisa i-furnace rhoqo – ukugaya umatshini wokubumba nge-die casting – - – - ukupholisa – unyango lobushushu bokupakisha
Okwesibini, umahluko ekusetyenzisweni
(1) Ibhola yentsimbi yekhabhoni, ibhola yentsimbi yekhabhoni ephezulu, ibhola yentsimbi ethwalayo — ibhayisekile, ibhereyitha, ipulley, umzila wesilayidi, imisebenzi yezandla, iishelufu, ibhola yendalo yonke, imithwalo, izixhobo, ukugaya
(2) Iibhola zentsimbi engatyiwayo — zihlala zisetyenziselwa ukususa nokupolisha iziqwenga ezahlukeneyo zezixhobo, ukuze umsebenzi ube nesiphumo esithambileyo nesikhanyayo: ubhedu, i-aluminium, isilivere njalo njalo. Ukongeza, iibhola zentsimbi zingasetyenziselwa ukugaya izinto zonyango kunye nezinto ezikrwada zeekhemikhali.
(3) Ibhola yentsimbi ephoswayo: ukumelana nobushushu obuphezulu, ifanelekile ekugayweni okomileyo, ifanelekile kakhulu kwizityalo zesamente
(4) Ibhola yentsimbi eqingqiweyo: ukumelana nokugqwala okunamandla, okufanelekileyo ekugayweni okumanzi, ekucutshungulweni kwezimbiwa kunye nezinye iibhola eziqingqiweyo zifanelekile ngakumbi.
3. Uthelekiso lwe-cast kunye ne-forging
(1) Ngokuphathelele ukumelana nokuguguleka, ubunzima bebhola ephezulu ye-chromium (HRC≥60) emva kokucinywa kunye nokuthomalaliswa buphezulu, obungaphezulu ngokuphindwe ka-2.5 kunokumelana nokuguguleka kwebhola yentsimbi eyenziweyo. Ngokweemvavanyo zesayensi, ukusetyenziswa kweetoni zeebhola ze-ore eziluhlaza zeebhola ezenziweyo kungaphezulu ngokuphindwe ka-2 kunokweebhola ezenziweyo.
(2) Ibhola yokuphosa ene-chromium ephantsi ayinakuguguleka kakuhle, isantya sokutyumza siphezulu, ukusebenza kwayo kuphantsi, kwaye ayikhuthazwa. Ibhola yokuphosa ene-chromium ephezulu inobulukhuni obuhle kwaye sisixhobo esisemgangathweni ophezulu esingagugulekiyo, esisetyenziswa kakhulu kwiimililo zebhola ezomileyo zesamente, kodwa ubulukhuni bebhola yokuphosa ene-chromium ephezulu abulunganga, kwaye kulula ukuphula kwimililo yebhola enobubanzi obungaphezulu kweemitha ezi-3, kwaye ixabiso liphezulu.
