Mabowo achitsulo opangidwa ndi ductile cast

Mabowo achitsulo opangidwa ndi ductile castamapangidwa makamaka ndi chitsulo cha ductile cast.

Chivundikiro chachitsulo cha ductile chili ndi maubwino awa:

chifukwa champhamvu kwambiri komanso kulimba kwachitsulo cha ductile iron, chivundikiro chachitsulo cha ductile chili pafupi30% yopepukakuposa chivundikiro chachitsulo chonyezimira chamtundu womwewo.

Mawonekedwe a chivundikiro chachitsulo cha ductile iron:

① Kulimba mtima kwabwino. 

Mphamvu yake ndi yopitilira 10 kuposa yachitsulo chotuwa.

②Kukana kwamphamvu kwa dzimbiri.

Kuyesa kwa dzimbiri kupopera madzi, dzimbiri masiku 90 ndi 1/40 chabe chitsulo chitoliro, ndi 1/10 wa imvi chitsulo chitoliro.Moyo wautumiki ndi nthawi 2 kuposa chitoliro chachitsulo cha imvi ndi nthawi 5 kuposa chitoliro chachitsulo wamba.

③Mapulasitiki abwino.

kutalika ≥7%, zofanana ndi zitsulo za carbon high.Koma imvi chitsulo elongation pafupifupi ziro.

④Mphamvu zapamwamba.

Kulimba mphamvu OB ≥420MPa, zokolola mphamvu OS ≥300MPa, ndi katatu wa imvi chitsulo chuma.
