METHOD OF CHARGE PREPARATION FOR LOW-CARBON FERROCHROME PRODUCTION

摘要

Application: The invention relates to metallurgy, particularly to a process for preparation of blends for the production of low carbon ferrochrome. SUMMARY OF THE INVENTION: chlorides of alkali and alkaline earth metals are introduced into the concentrate during the chromium enrichment immediately po- spe its processing on a vacuum filter in an amount of 0.5-2.0% by weight of the concentrate in a saturated aqueous solution. The furnace is charged with seed-ore part of charge and chromium concentrate with lime sequentially proplavl dissolved charge.
