Abstract：This paper proposes to use high-carbon pre-reduced iron-carbon alloy pellets in Consteel EAF smelting process after pre-reduction,crushing and high-pressure forming with iron oxide raw materials,graphite powder and additives,which increases carbon content and improves the technical specifications of the entire scrap steel arc furnace smelting process.The preparation process,product composition and physical test performance of the pellet were introduced.The influence of the pellets on the continuous feeding arc furnace smelting technical index after the addition of the pellet was evaluated by material and heat balance,and the industrial test was carried out in a 70 t continuous arc furnace.The results show that after adding 20 kg pellets per ton of steel,the average smelting cycle was shortened by 7.45 min,and the average ton steel power consumption was reduced by 8.78 kW·h.
