Optimisation of steel plant recycling in Finland: dusts, scales and sludge

Reduction Behaviour of Self-reducing Blends of In-plant Fines in Inert Atmosphere

“…6) Recycling of these materials in existing iron-and steelmaking processes without pre-treatment is difficult due to the adverse impact on the process operation and the product quality which might be caused by the impurities, fine particle size, high moisture content, etc. 7) Attention has been paid by several researchers to investigate different routes of effective utilization of these materials as well as their impact on process performance. Producing agglomerates with self-reducing property which is further processed to produce direct reduced iron (DRI) followed by charging in existing iron and steelmaking processes has been previously suggested as a possible recycling method for dust and sludge that currently are landfilled.…”

Potential of Air Classification for Zinc Management in Dust Recycling in Ironmaking

“…6) Zn is an unwanted component in the feed material to the sinter plant because it causes problems in the BF operation. Zn forms crusts in the upper part of the BF and accumulates in the furnace lining which consequently deteriorates.…”

On the Application of 3D X-Ray Microtomography for Studies in the Field of Iron Ore Sintering Technology

“…Optimal sinter mixtures design in the modern and future conditions is constrained by the following factors (Hunt, 2004, Makkonen et al, 2002, Shatokha et al, 2011:…”
