FIELD: metallurgy.SUBSTANCE: briquette contains carbon containing substance and iron containing material including cast iron and steel shavings, iron oxides, lime dust and dust of ventilation system of electric arc furnaces as sources of iron oxide. Components of the briquette are contained in the following ratio, wt %: carbon containing substance - 10-15; lime dust - 5-10; iron containing material - rest, at that content of dust of the ventilation system of the electric arc furnaces is 10-15%. In the iron containing material quantity of the cast iron and steel shavings is in ratio 1:1.EFFECT: reduced volume of slag during melting and increased quality of composition correction of the melted cast iron.2 cl, 2 tbl, 1 ex |
