Nwayo konsèp: Precision kòmanse ak pite

Foundry-grade pure iron lumps (2N-4N purity) are ultra-refined iron billets engineered to serve as the foundational material for high-integrity castings. Unlike conventional foundry pig iron (typically ≤99.9% pure with 3.5–4.5% carbon and trace impurities), these lumps undergo advanced purification processes to achieve >99 . 95% Fe (4n klas) . Sa a elimine eleman prejidis tras (tankou, sn, sb, bi, pb, elatriye .) ki lakòz fragilite, porosite, ak echèk fatig nan eleman kritik.

Koule pwosesis métallurgique

Anvan tout koreksyon fè minrè → pre-defini → "trip raffinage" → vakyòm decarburization → elektwochaj renovasyon → kontwole solidifikasyon

Enperatif la nan nivo ultra-ba salte

Boul nou yo diminye risk sa yo nan:

Kabòn (c) mwens pase oswa egal a 0 . 02%: anpeche presipitasyon carbure nan chalè-trete alyaj.

Souf (yo) mwens pase oswa egal a 0 . 005%: elimine kout cho nan moule asye.

Fosfò (p) mwens pase oswa egal a 0 . 015%: kenbe duktilite nan tanperati kriyojenik.

Pwogrè kle:

- Deep Desulfurization (<0.005% S via Mg-Ca injection)

- Vacuum oksijèn decarburizasyon (VODC) diminye C a 0.002%

- Segregasyon eleman tras lè l sèvi avèk solidifikasyon direksyon
