METHOD OF PRODUCING LOW-CARBON NICKEL-CONTAINING FERROCHROMIUM

摘要

Usage: relates to metallurgy, particularly to a method of manufacturing ferrochrome silicothermic. SUMMARY: remelting in a furnace waste nickel, oxide portion of the charge and the melt recovery ferrosilicochrome excess. As part of the charge of the oxide is used at a ratio of melt rudnoizvestkovy waste mass and chrome ore within 0.6-1.4, and the recovery Oxide Nogo melt is carried out until complete removal of excess electricity ferrosilicochrome 10-20% of the required 1 h. P. f BACKGROUND Table 3.
