Soosaarayaasha mishiinada deminta soo noqnoqda ee sarreeya si kooban u sharax habka nuugista birta
1. Si buuxda loo xanibay
Habka: Kuleylinta ka sarreysa Ac3 ilaa 30-50°C → ilaalinta kulaylka → qaboojinta ilaa 500 darajo foornada → qaboojinta hawada ilaa heerkulka qolka.
Ujeeddo: in la sifeeyo hadhuudhka, qaabdhismeedka lebiska, hagaajinta balaastiga iyo adkaanta, baabi’inta walbahaarka gudaha, iyo fududaynta mashiinada.
2. Ku -shubista kuleylka
Habka: kululaynta korka Ac3 → ilaalinta kulaylka → qaboojin degdeg ah ilaa heerkulka isbeddelka pearlite → joogitaanka isothermal → isbeddelka P → qaboojinta hawada;
Ujeedo: Ibid. Laakiin wakhtigu waa gaaban yahay, fududahay in la xakameeyo, deoxidation iyo decarburization waa yar yihiin. (Ku haboon birta daawaha iyo qaybo kaarboonka birta ah oo waaweyn oo leh qaboojin aad u xasiloon).
3. Dhiirrigelinta Spheroidizing
Fikradda: Waa habka spheroidization cementite ee birta ah.
