Impembelelo yezinto ezintlanu eziphambili ze-ductile kwi-procings

Ukuqulunqwa kwekhemikhali ye-guccike ikakhulu kubandakanya izinto ezintlanu zekhabhoni, isilicon, i-manganese, isalfure kunye ne-phosphorus. Kwezinye iindawo ezifihlakeleyo ezineemfuno ezizodwa kumbutho kunye nentsebenzo, inani elincinci lezinto zokwabalwa nazo zibandakanyiwe. Ngokungafaniyo nje i-iron yentsimbi eqhelekileyo, intsimbi ye-ductile kufuneka ibe nexabiso lezibalo ze-spheroidal yentsalela ukuze kuqinisekiswe ukubekwa kwegraphiriya. Senza uluhlu olubanzi lweIimbapho zeelori zaseJapan ne-European, njengeI-bracket yasentwasahlobo, Intwasahlobo yeNtwasahlobo,I-PIN yentwasahlobo kunye ne-bushing yentwasahlobo.

I-1, i-carbon kunye ne-carbon elinganayo i-carbon elinganayo: ikharbon yindawo esisiseko yentsimbi, ikhabhoni ephezulu iyanceda i-pictoriation. Nangona kunjalo, umxholo wekhabhoni ephezulu uya kubangela ukubaleka kwegrafu. Ke ngoko, umda ongaphezulu wekharbon olinganayo kwi-gucile iron usekwe kumgaqo weforati.

2, Umgaqo-siseko wokukhetha i-Silicon: I-Silicon yinto eqinileyo ye-prographiction. Kwintsimbi yentsimbi, i-silicon ayinakukwazi ukunciphisa ngokufanelekileyo umkhwa womlomo omhlophe kwaye yonyuse inani le-ferrite, kodwa ikwanendima yokuhlaziya amaqela e-Etheectic kunye nokuphucula imijikelezo ye-dishere.

3, Umgaqo wokukhethwa kwe-Mangane: njengoko umxholo wesalfure kwi-guccile sentsimbi sele uphantsi kakhulu, sukungafuni kakhulu i-manganese ukuba ichaphazele i-sulfure, indima ye-manganese kwi-guarlite ye-duclite ikakhulu ekwandiseni uzinzo lwepearli.

4, I-Phosphorus Ukhetho: I-phosphorus yinto eyenzakalisayo, iphantsi kakhulu sloubioungus kwi-iron. Ngokubanzi, isezantsi umxholo we phosphorus kwi-ductile yentsimbi, engcono.

I-5, I-Sulfuur Speciation: I-Sulfur yinto efunyanwayo, inomzimba onqabileyo ongenayo iMagnesium, i-SURDFUR ye-SPDOUR, ubukho be-slag, buyabangela i-Slag, ukuthambisa kunye nezinye iziphene.

6, imigaqo-siseko yokukhetha i-spiroid: Kwindawo yokuqinisekisa ukuba isiphelo se-spheroidal, i-magnesium ye-magnesium kunye ne-magnesium kunye nomhlaba onqabileyo kufuneka ibe sezantsi kangangoko kunokwenzeka. I-Magnesium kunye nentsalela yomhlaba enqabileyo iphezulu kakhulu, iyakonyusa umkhwa womlomo omhlophe wolwelo lwentsimbi, kwaye iya kuchaphazela ubume bemida yengqolowa.
