| description | The invention relates to a method of producing ferrochromium by the granulation of a melt comprising the steps of providing a ferrochromium melt comprising (wt. %): C: 1 - 9;
Cr: 25 - 70 and Si: ¤ 2.0. The method includes the steps of feeding the melt to a distribution unit, subj ecting the melt to granulation by disintegrating the melt above and/or within cooling water held in a cooling tank, solidifying the disintegrated melt within the cooling water, thereby obtaining a granulated ferrochromium material with a mean size in the range of 12-50 mm wherein the amount of fines having a size of less than 4 mm is limited to 7 %. |
