Ifomu yoku-odola kufuneka iquke ezi zinto zili-11 zilandelayo:
1. Ubungakanani (iinyawo, iimitha okanye inani leentonga)
2. Igama lezinto (umbhobho oqhelekileyo wentsimbi engenamthungo)
3. Amanqanaba (ayi-16 iyonke: P1, P2, P22, P11, P22, P91)
4. Indlela yokuvelisa (ukugqiba okushushu okanye umzobo obandayo)
5. Sebenzisa enye yezi nkcukacha zilandelayo: 1), inombolo yeserial yobukhulu bodonga lwe-NPS kunye nombhobho, 2), ububanzi bodonga olungaphandle kunye nobukhulu bodonga oluqhelekileyo, 3), ububanzi bodonga olungaphandle kunye nobukhulu bodonga obuncinci, 4), ububanzi bodonga olungaphakathi kunye nobukhulu bodonga oluqhelekileyo, 5), ububanzi bodonga olungaphakathi kunye nemiyalelo yoku-odola ubukhulu bodonga obuncinci
6. Ubude (bahlulwe baba bubude obungaguqukiyo kunye nobude obungenasiphelo)
7. Ukuphelisa ukucutshungulwa.
8. Iimfuno zokukhetha (uxinzelelo lwamanzi kunye nokuphambuka kobunzima okuvumelekileyo).
9. Iingxelo zovavanyo ezifunekayo (jonga i-A530).
10. Inombolo eqhelekileyo. 11Iimfuno ezikhethekileyo okanye naziphi na iimfuno ezongezelelweyo ezinganyanzelekanga.
Izixhobo kunye nokuveliswa
1. Imibhobho yentsimbi eqhelekileyo ingagqitywa ngobushushu okanye itsalwe kubanda, kwaye idlule kunyango lokugqibela lobushushu olufunekayo ngokomgangatho.
2. Intsimbi ye-P2 kunye ne-P12. Ezi ntlobo zimbini zentsimbi kufuneka zenziwe kusetyenziswa inkqubo yokunyibilikisa iinkozo ezirhabaxa. Ukuba kukho iimfuno ezikhethekileyo zobungakanani bengqolowa okanye inkqubo yokususa i-oxidation, kufuneka kuvunyelwane ngazo ngumthengi kunye nomenzi wentsimbi.
3. Unyango lobushushu
1. Ngaphandle kwentsimbi yodidi lwe-PSC, P23, P91, P92, P122 kunye ne-P911 kwaye njengoko kuchaziwe, zonke iintlobo zeepayipi ezimiselweyo mazifudunyezwe kwaye zinikezelwe kwimeko efakwe ngokupheleleyo, efakwe i-isothermal okanye efakwe i-normalized kunye ne-tempered. Ukuba zinikezelwa kwimeko efakwe i-normalized kunye ne-tempered, ubushushu obuncinci bokufudumala bentsimbi yodidi lwe-P5, P5B, P9, P21 kunye ne-P22 bube yi-675°C. Ubushushu obuncinci bokufudumala bentsimbi yodidi lwe-P1, P2, P11, P12 kunye ne-P15 bube yi-650 ℃
2. Unyango lokugqibela lobushushu lwentsimbi ye-P92 kunye ne-P911 kufuneka lube yi-normalizing ubuncinane kwi-1040 ℃ kwaye lube yi-tempering ubuncinane kwi-730 ℃.
