Abstract

For years, the iron and steel industry has been in search of new processes for an efficient production of virgin steel as well as for the recycling of its by-products, especially for those containing zinc. Considering these objectives, Paul Wurth S.A., in cooperation with ProfilARBED, has developed a process using the multiple-hearth furnace and coal fines as the reductant and main energy source. A trial plant with a capacity of 2 t/h was built and has been operated for more than one year at the ProfilARBED Belval site. This paper reports on the trial campaigns, which have given most promising results.
