SUMMARY:Valorization of LF slag: the Pittini Group tests Tenova's air granulation process
DESCRIPTION:Valorization of LF slag: the Pittini Group tests Tenova's air granulation process

The Pittini Group has historically been active and committed to the reduction and valorization of steelshop residues and, in particular, Ferriere Nord plant in Osoppo was the first in Europe in 2000 to implement the recycling of LF slag by injecting it into EAF in lime replacement.
In last two years, the Pittini Group tested, at Acciaierie di Verona and Ferriere Nord sites, an industrial-scale pilot plant for the valorization of the ladle furnace slag through an air granulation process developed and designed by Tenova S.p.A.
Tenova developed a methodology for the design of dry slag granulation process based on Computational Fluid Dynamic modelling validated by the laboratory testing in a pilot plant.
The present work shows the results of the dry slag granulation industrial testing, performed at Ferriere Nord plant, their consistency with the Tenova methodology in the process design together with validation through testing at laboratory scale pilot plant facility. In addition, the first study for the industrialization of the dry slag granulation process is presented, along with the various opportunities for valorization of the final product.
