2, da ruwa zafin jiki yana da babban tasiri a kan sanyaya iya aiki, don haka yana da kula da canji na yanayi zazzabi. Kamar yadda ruwan zafin jiki ya karu, da sanyaya damar rage sharply, da kuma zafin jiki kewayon matsakaicin sanyaya kudi matsawa zuwa low temperature.When da ruwa zafin jiki ya wuce 30 ℃, da sanyaya gudun a cikin kewayon 500-600 ℃ rage-rage a fili, wanda sau da yawa take kaiwa zuwa ga ƙirƙira ba za a taurare, amma yana da kadan tasiri a kan sanyaya gudun a cikin kewayon da ruwa mai sanyi ℃ 6. kudi zai ragu da kusan 50%.

3. Lokacin da ruwa ya ƙunshi iskar gas (kamar sabon ruwa), ko ruwan da aka gauraye da ƙazanta marasa narkewa, kamar mai, sabulu, laka, da sauransu, zai rage ƙarfin sanyaya, don haka amfani da kulawa ya kamata a ba da kulawa ta musamman.
Bisa ga sanyaya halaye na ruwa, ruwa H za a iya amfani da quenching da sanyaya na carbon karfe forgings tare da kananan sashe size da sauki shape.Quenching, dole ne kuma lura: kiyaye ruwa zafin jiki a kasa 40 ℃, mafi kyau tsakanin 15 zuwa 30 ℃, da kuma kiyaye ruwa ko ruwa wurare dabam dabam, don halakar da ƙirƙira surface tururi membrane, kuma zai iya yin amfani da quench down workpiece a lokacin swing workpiece (swing workpiece) Juyar da membrane tururi, ƙara matakin sanyaya tsakanin 500-650 ℃, yanayin sanyaya, guje wa samar da maki mai laushi.
