Fomu yoyitanitsa iyenera kukhala ndi zinthu 11 zotsatirazi:
1. Kuchuluka (mapazi, mamita kapena chiwerengero cha ndodo)
2. Dzina lachinthu (chitoliro chosasunthika chachitsulo chachitsulo)
3. Miyezo (16 yonse: P1, P2, P22, P11, P22, P91)
4. Njira yopanga (kumaliza kotentha kapena kujambula kozizira)
5. Gwiritsani ntchito chimodzi mwa izi: 1), NPS ndi chitoliro khoma makulidwe nambala siriyo, 2), m'mimba mwake ndi mwadzina khoma makulidwe, 3), awiri akunja ndi osachepera khoma makulidwe, 4), m'mimba mwake mkati ndi mwadzina khoma makulidwe , 5), awiri amkati ndi osachepera khoma makulidwe kuyitanitsa malangizo
6. Kutalika (kugawidwa mu utali wokhazikika ndi utali wosadziwika)
7. Mapeto processing.
8. Zofunikira pakusankha (kuthamanga kwa madzi ndi kupatuka kovomerezeka).
9. Malipoti oyeserera ofunikira (onani A530).
10. Nambala yokhazikika.11 Zofunikira zapadera kapena zofunikira zina zowonjezera.
Zida ndi kupanga
1. Mapaipi achitsulo omwe amatchulidwa amatha kukhala otentha kapena ozizira, ndipo adalandira chithandizo chomaliza cha kutentha chomwe chimafunidwa ndi muyezo.
2. P2 ndi P12 kalasi zitsulo.Mitundu iwiriyi yachitsulo iyenera kupangidwa pogwiritsa ntchito njira yosungunuka yosungunuka.Ngati pali zofunikira zapadera za kukula kwa tirigu kapena njira yochepetsera thupi, ziyenera kuvomerezedwa ndi wogula ndi wopanga zitsulo.
3. Chithandizo cha kutentha
1. Kupatula PSC, P23, P91, P92, P122 ndi P911 chitsulo giredi ndipo monga tafotokozera, magiredi onse a mapaipi odziwika adzatenthedwanso ndikuperekedwa mumkhalidwe wokhazikika, wa isothermal annealed kapena normalized and tempered state.Ngati iperekedwa mu chikhalidwe chokhazikika komanso chozizira, kutentha kochepa kwa P5, P5B, P9, P21 ndi P22 grade zitsulo kudzakhala 675 ° C.The osachepera tempering kutentha kwa P1, P2, P11, P12 ndi P15 kalasi zitsulo ayenera kukhala 650 ℃.
2. Chithandizo chomaliza cha kutentha kwa P92 ndi P911 kalasi yachitsulo chiyenera kukhala chokhazikika pamtunda wa 1040 ℃ ndi kutentha osachepera 730 ℃.
