China OEM caadadii shubka ductile bir tuurista byhabka shubista maalgashiga dhunka lumay. Ductile iron, kaas oo sidoo kale loo yaqaan birta ducitle cast iron, birta nodular, birta graphite spheroidal, graphite graphite cast iron, ama birta SG oo kooban.Marka graphite uu joogo sida qayb yar, wareegsan, iyo qaybo si fiican loo qaybiyey, saamaynteeda daciifintu waa yar tahay oo birta kabka sida waxay yeelan doontaa ductility sare. Noocaan kabka ah waxaa loo yaqaannaa birta ductile ama birta nodular ama graphite spheroidal ama si fudud SG iron. Noocan garaafka ah waxaa lagu gaari karaa in lagu daro magnesium elemental ama cerium ama isku darka labada walxood si loo dhalaalliyo birta. Magnesium waxa lagu daraa tiro dhan 0.07 ilaa 0. 10% waxa ku xiga in lagu daro ferro-silicon si kor loogu qaado garaafaynta. Inta lagu jiro xoojinta, magnesium wuxuu ka caawiyaa qaybinta graphite ee birta oo dhan.
Birta Ductile-ka waxay leedahay saami ka xoog-ilaa-miisaan oo ka wanaagsan, farsamayn fiican iyo qiimo saameeyn sare leh. Intaa waxaa dheer, qaybaha birta ductile waxaa lagu soo saaraa habka shubista taas oo si fiican loo xakameyn karo qaabka qaybta marka la barbar dhigo foornada foornada. Sidaa darteed, qaybo badan oo ay ka mid yihiin ulaha daloolinta iyo isku xidhka ulaha lagu sameeyo sida caadiga ah dhibicda foorida ayaa si isa soo taraysa loogu bedelayaa shubka birta ductile.

Dulqaadka Qaadashada waxa lagu gaadhi karaa Maalgelinta Qaadista:
Marka loo eego agabka wax-ku-xidhaha ee kala duwan ee loo isticmaalo samaynta qolofka, shubista maalgelinta waxa loo qaybin karaa shubka silica iyo shubista dhalada biyaha. Habka shubista silica sol ayaa leh dulqaadka Cabbiraadda Cabbiraadda (DCT) iyo Dulqaadyada Qaadashada Joomatari (GCT) ka wanaagsan habka dhalada biyaha. Si kastaba ha ahaatee, xittaa iyadoo la raacayo habka wax- shubista, Darajada Dulqaadku waxa ay ka duwanaan doontaa wax kasta oo kabka ah sababtoo ah awooddooda kala duwan. Aasaaskayagu wuxuu jeclaan lahaa inuu kula hadlo haddii aad hayso codsi gaar ah oo ku saabsan dulqaadka loo baahan yahay. Halkan kuwan soo socda ayaa ah darajada dulqaadka guud ee aynu ku gaadhi karno labadaba silica sol iyo hababka shubista dhalada biyaha si gooni gooni ah:
✔ Darajada DCT ee Silica Sol Lost Wax tuurista: DCTG4 ~ DCTG6
