Sainaithint cáilíochta púdar ferro chrome ardcharbóin

Ard-charbóin ferrochrome mar cheannach mór táirgí, tá sé an-tábhachtach a aithint go maith nó olc. Riachtanais táirgthe ferrochrome ardcharbóin tá amhábhair ferroalloy méine cróimiam, cóc agus shilice, d'fhonn an cineál slaig a choigeartú, ní mór méid áirithe de luaith bán nó dolaimít a chur leis, tá ceanglais an-ard ag monaróirí ferrochrome ardcharbóin le haghaidh amhábhar, a cheangal ar ard. ábhar na n-eilimintí úsáideacha, dea-fheidhmíocht, méid na gcáithníní maith, agus go mór coigilte fuinnimh agus laghdú tomhaltais.
