Abstract:

Danieli MIDA Hybrid minimills, a true sustainable green steel production
Energy saving and low CO2 emission solutions

Competitiveness over traditional process is achieved by the implementation of the processes across the whole cycle, from DRI and scrap through finished added-value quality long and flat products.

Energy savings are assured starting from by direct continuous charge of metallics in the Digimelter – the Danieli digital melting unit. DRI is produced by Energiron plants which are natively designed to use also hydrogen as reducing gas. Scrap is it treated and managed in a smart way thus improving the efficiency of the melting process.

Patented Danieli Universal Endless, endless casting-rolling process, is applied to both flat (QSP-DUE®) and long products (QLP-DUE®).

They extraordinary performances of Dysencaster® and Octocaster® casting technologies allow the production of quality final products in a wide range of steel grades and sizes.

The absence of reheating furnace in the QLP-DUE® process makes it possible to generate zero NOx, SOx and CO2 direct emissions during casting-rolling.

Thanks to Q-One electrical feeder, Digimelter melting unit can be powered by renewable energies.
