| description | The invention relates to the field of ferrous metallurgy. A method for ferroalloys manufacture involves melting of charge materials in the furnace, discharge of a melt from it in a ladle which are located in cascade, addition in a melt of limestone screening of CaO manufacture in the shaft furnaces, at that the specified refining additives are warmed up to temperature on 50 - 100 ?C below the temperature of CaCO3 dissociation and before the discharge of a melt from the furnace are loaded on a back surface of the first ladle in the cascade in quantity of 3-5 weight % from capacity of a melt in this ladle. The invention increases manufacture of ferroalloys and reduces the cost price of metal. |
