Ferrosilikonning umumiy tasniflari va milliy standartlari qanday?
Ferrosilikon, xomashyo sifatida koks, po'lat qoldiqlari va kvarts (yoki kremniy) yordamida elektr pechlarida eritilgan temir-kremniy qotishmasi po'lat ishlab chiqarish sanoatida deoksidlovchi sifatida keng qo'llaniladi. Uning tasniflari va milliy standartlarini tushunish barqaror va yuqori sifatli materiallarga-tayanadigan tarmoqlar uchun zarur. Quyida biz Xitoy milliy standartlari bilan belgilangan ferrosilikonning asosiy jihatlarini ajratamiz.
1. Tasniflash
Ferrosilikon ishlab chiqarish usullari va tarkibiga ko'ra to'rt turga bo'linadi:
- Yuqori-Ferrosilikon kremniy (GG)
- Standart ferrosilikon (PG)
- Kam-alyuminiy ferrosilikon (DL)
- Yuqori-Soflikdagi ferrosilikon (GC)
Yuqori{0}}soflikdagi ferrosilikon, ayniqsa, ifloslik tarkibini minimallashtirish uchun tashqi tozalash jarayonlari orqali ishlab chiqariladi.
2. Baholarni belgilash tizimi
Sinf nomlash konventsiyasi aniq tuzilishga ega:
- Birinchi ikkita harf ferrosilikon turini bildiradi (masalan, GG, PG, DL, GC).
- Buning ortidan "FeSi" mahsulot kodi keladi.
- Keyingi raqam kremniy tarkibining pastki chegarasini bildiradi (masalan, 97 kamida 97% kremniyni bildiradi).
- Qo'shimcha belgilar asosiy aralashmalarning yuqori chegaralarini belgilaydi (masalan, "Al1,5" alyuminiy miqdori 1,5% ga cheklanganligini bildiradi).
- Yuqori{0}}tozalikdagi ferrosilikon uchun oxirgi harf (A, B yoki C) ikkilamchi ifloslik darajasini tasniflaydi.
3. Kimyoviy tarkibiga qo'yiladigan talablar
Ferrosilikon to'rtta toifa bo'yicha 40 toifaga bo'linadi, ularning har biri qat'iy kimyoviy tarkib standartlariga ega:
- Yuqori-kremniy ferrosilikonning kimyoviy tarkibi

4. Jismoniy holatga qo'yiladigan talablar
Ferrosilikonning jismoniy shakli ham tartibga solinadi:

Chelik ishlab chiqarishdan tashqari ilovalar
Ferrosilikon asosan po'lat ishlab chiqarishda oksidlovchi sifatida ishlatilsa-da, u past qotishma konstruktiv po'lat, bahor po'lati, podshipnik po'lat-, issiqlikka chidamli po'lat va elektr kremniyli po'latda-qotishtiruvchi vosita sifatida ham xizmat qiladi. Bundan tashqari, u ferroqotishma ishlab chiqarishda va kimyo sanoatida kamaytiruvchi vosita sifatida ishlaydi.
