Development of the process production partially metallized iron-ore burden materials on the base ore-carbonic composition for traditional metallurgical technology

For the reason increasing of metallurgical value charge materials domain production was researched possibility of the reception partly metallize pallets from ore-flux-fuel composition. As main raw material was used iron-ore concentrate Inguleckogo GOKa (64,7 % Fe), with additive coke breeze of fraction 0-3 mm and quicklime, which then mingled and were granulated on plate granulator. Got pellets (with 12-17 % dispersed carbon) after fixing on surface defensive layer by thickness 2,0-2,5 mm from mixture of the concentrate and quicklime (1:1) mingled with solid fuel.
