Gæðaauðkenning á hákolefnis járnkrómdufti

Hár kolefni járnkróm sem stór kaup á vörum, það er mjög mikilvægt að bera kennsl á gott eða slæmt. Hár kolefnisferrókróm framleiðsluþörf járnblendi hráefni eru krómgrýti, kók og kísil, til þess að stilla gjallgerðina, þarf að bæta við ákveðnu magni af hvítum ösku eða dólómíti, hár kolefnis járnkróm framleiðendur fyrir hráefni eru mjög miklar kröfur, krefjast mikillar innihald gagnlegra þátta, góð afköst, góð kornastærð og mikil orkusparnaður og minni neysla.
