1) Mu austeteite imothermal kusinthika chithunzi, ndiye kuti pafupifupi 500-600 ℃, madzi ozizira siwachangu mokwanira, nthawi zambiri amayambitsa kuzizira komanso kuzizira kosakwaniraKutalikaNdipo mapangidwe a "malo ofewa". Kwenikweni Kusintha Kwa Marnenstem Sydiction, ndiye kuti, pafupifupi 300-100 ℃, madzi ozizira ndiwachangu kwambiri, ndikupanga kupsinjika kwakukulu kwamkati, kumapangitsa kuwonongeka kwa mkati, kumabweretsa.

2) Kutentha kwamadzi kumakhala ndi chisonkhezero chachikulu pa kuzizira, motero kumakhala kovuta kusintha kwa kutentha kwa mawonekedwe. Pamene kutentha kwamadzi kumakwera, kuwongolera kozizira kumatsikira kwambiri, ndipo kutentha kwamitundu yozizira kwambiri kumayenda kutentha pang'ono.Kungoyiwala, koma sichimalimbikitsa kwambiri pa chiwongola dzanja cha ma 15% mpaka 60 ℃, kuchuluka kwa kuzizira kumachepa pafupifupi 50%.

Madziwo akakhala ndi mpweya wambiri (monga madzi osinthika atsopano), kapena madzi osakanizidwa ndi zosakanizidwa, monga mafuta, sopo, etc., chidwi chapadera chiyenera kulipidwa ku ntchito ndi kasamalidwe ka.
Malinga ndi madera ozizira amadzi, madzi nthawi zambiri h amatha kugwiritsidwa ntchito kuzirala kozizira kwa kabonizitsulo zowoneka bwinondi kukula kocheperako komanso mawonekedwe osavuta, ayeneranso kuzindikira: Sungani kutentha kwa madzi pansi pa 1500-650 ℃, kuwononga madzi ozizira pakati pa 500-650 ℃, kuwononga madzi malo ofewa.
