<p>The invention relates to an improved process for recycling steel dusts, which with a carbon-based reducer, and mixed with a bonding agent (7) and water and pressed forming briquettes (2"), has a high-pressure pump (8) in the flow of water (9) heated at 40/ 60ºC, passing through a sieve (15) sending the remains (2') back to the hopper before the press (13). The briquettes (2") pass through a maturation tunnel (16) heated with air between 80 and 100ºC; they are passed through a second sieve (23) with an opening of 20% of their size; they pass to containers (17) in which, once full, unit heaters (18) are introduced and they are covered for a few hours, and finally they are subsequently transferred to a storage (19) in which they are deposited while waiting to be used in the steel plant furnace (1), not being used before 24 hours.</p> |
