FferoChrome
Maint:1-100mm
Mae Ferrochrome (FeCr) yn aloi o gromiwm a haearn sy'n cynnwys rhwng 50% a 70% o gromiwm. Mae dros 80% o ferrochrome y byd yn cael ei ddefnyddio i gynhyrchu dur di-staen.Yn ôl cynnwys carbon, gellir ei rannu'n: Fferochrome carbon uchel / HCFeCr (C: 4% -8%), ferrochrome carbon canolig / MCFeCr (C: 1% -4%), ferrochrome carbon isel / LCFeCr (C: 0.25 %-0.5%),Fferrochrome micro-garbon/MCFeCr:(C:0.03 0.15%).Tsieina ar gyfer cyfran gynyddol o gynhyrchu fferochrome y byd.

Mae Ferrochrome (FeCr) yn aloi o gromiwm a haearn sy'n cynnwys rhwng 50% a 70% o gromiwm. Mae dros 80% o ferrochrome y byd yn cael ei ddefnyddio i gynhyrchu dur di-staen.Yn ôl cynnwys carbon, gellir ei rannu'n: Fferochrome carbon uchel / HCFeCr (C: 4% -8%), ferrochrome carbon canolig / MCFeCr (C: 1% -4%), ferrochrome carbon isel / LCFeCr (C: 0.25 %-0.5%),Fferrochrome micro-garbon/MCFeCr:(C:0.03-0.15%).Tsieina am gyfran gynyddol o gynhyrchiant fferochrome y byd.
Cais:
① Wedi'i ddefnyddio wrth gynhyrchu dur di-staen，Mae dur di-staen yn dibynnu ar gromiwm am ei ymddangosiad a'i wrthwynebiad i gyrydiad.
② Fel y prif ychwanegyn aloi mewn gwneud dur
③ Fel ychwanegyn anhepgor yn y broses o fwyndoddi dur carbon isel
