SUMMARY:Feralpi way of substitution of coal injected in EAF with alternative materials based on polymers 
DESCRIPTION:The substitution of the use of carbon sources in Steelmaking became in last years an even more important topic considering the necessity both to increase the possibility of reuse of the residues also from other sector and also to reach a condition of strongly reduction of the global use of carbon sources to arrive at a condition of zero CO2 emissions.
In particular, Feralpi Group has followed this route since several years starting with trials of basket charging of alternative materials arriving in last configuration to totally substitute the coal injected by wall mounted lances with polymers obtained by the plastic residues.
Thanks to this substitution Feralpi Siderurgica became fist EAF plant with only polymer injected by wall mounted lances and able to eliminate the solid natural carbon sources to enable a correct production process and an appropriate slag foaming.
In this way enabling the demonstration of a feasible industrial approach for the use of alternative materials
Here the activity of the first period of the OnlyPlastic project is presented. The industrial injection system is described, together with a new injector able to efficiently deliver the plastic residues into the Feralpi Lonato EAF, with the aim of promoting the reduction process and the slag foaming in a circular economy approach.
The paper includes also the design and realization of an industrial injection system and a new injector able to inject efficiently the material into EAF to promote reducing process and slag foaming.
