Abstract

Organic binder is used for briquetting manganese ore and coke fines to fabricate composite briquette with high strength and resistivity, thermal stability, good softening property and reducibility through simple process, which is advantageous to deep insertion of electrodes, improvement of permeability in burden layer and stabilization of operating process during smelting. Significant effects have been obtained from the industrial application in an 1800kVA ferromanganese arc furnace charged with 50 % of composite briquette: 20 % electricity was saved and 9.6 % more manganese was recovered.
