Steel production routes
Production of steel in the world is carried on
with different technologies, driven by the raw
materials avalability:
In China, steel is primarily produced via BFBOF route
In North America steel is primarily produced
by Electric Arc Furnaces
Environmental concerns are driving Europe
to the adoption of less polluting
technologies, increasing EAF production

Flexible Modular Furnace
Nowadays, countries like India, China, and
others, need a technology ready to effectively
use high percentage of hot metal in the steel
production but with enough flexibility to adapt
to the variabilities of the market:
Leverage on the larger scrap availability
Utilize the existing hot metal production
equipment
Adopt a more environmental sustainable
technology
