Danieli Hybrid Minimill is a compendium of Danieli original and patented individual technologies, including hybrid technologies, that make the difference.
These technologies are perfectly integrated and harmonized by advanced process control systems and supported by smart digital and power devices and self-learning tools, according to I4.0 concepts developed by Danieli Automation.
Danieli minimill technologies and related services lead to the widest application of circular economy concepts, where metallics are transformed into steel with the most efficient energy-saving processes, and also make use of renewable energies, without disturbances to the electric networks.

Clean scrap from automated scrap yards and DRI are charged hot and continuously, requiring less energy for melting.
The Digimelter® melting unit powered by Q-One® digitally controls power loads, minimizing disturbances to the electric networks. Hybrid by design, it allows steelmakers to exploit renewable energies produced at the site, right from the beginning or at a later stage.
Endless casting-rolling for flat or long products and induction heating make it possible to operate at the overall lowest energy costs and without the use of reheating furnaces.

Fume-treatment plants treat gases in compliance with the strictest regulations, up to 4 million m3/h, and zero-waste water is achieved, heat is recovered through absorbers, carbon is captured by patented systems, and noise dispersion is controlled by new Acou-Stack solutions.
Slag is converted into Ecogravel industrial aggregate for use in road paving and cement production, with excellent characteristics. Additionally, automotive shredder residue can be processed by Synca, in order to recover the metal parts. Plastic and rubber, properly treated, are usable as carbon substitute in electric steelmaking.
All this means less emissions, increase of waste-recycling into by-products and consequent lower use of natural resources.
Furthermore, as less carbon is released, present/future carbon tax obligations will be reduced.
