Danieli MIDA: A New Era of Steelmaking for Australia

Generation Steel is bringing Danieli's revolutionary MIDA minimill technology to Collie. The first deployment of its kind in Australia, delivering compact, efficient, lower-carbon steel production.

What is Danieli MIDA?

MIDA (Minimill Innovative Danieli Architecture) is Danieli's next-generation steelmaking concept that integrates melting, casting and rolling into a single continuous process. Developed by Italy's Danieli Group, one of the world's largest suppliers of steelmaking equipment, MIDA represents a paradigm shift from conventional long-product steel mills.

Unlike traditional plants that require separate facilities for each production stage, the MIDA layout connects the Electric Arc Furnace directly to a continuous caster and inline rolling mill. This eliminates intermediate reheating, dramatically reducing energy consumption and physical footprint.

The result is a highlighy compact, flexible plant capable of producing finished long products, incluing rebar, merchant bar and wire rod, from 100% recycled scrap steel in a single uniterrupted workflow.

Electric Arc Furnace

Recycled steel scrap is charged into a high-power EAF, where electrodes generate intense heat to melt the material into liquid steel. Danieli's EAF technology achieves rapid tap-to-tap times with optimised energy input.

The MIDA Process: From Scrap to Finshed Steel

Three integrated stages working as one continuous operation. No intermediate storage, no reheating, no wasted energy.

1 Continuous Casting

Molten steel flows directly from the furnace into Danieli's high-speed continuous caster, solidifying into billets at precisely controlled temperatures. The MIDA layout preserves heat from the melt, elmininating the need for a separate reheating furnace.

Inline Rolling Mill

Hot billets pass directly into the rolling mill in a single continuous motion, shaped into finished long products such as rebar and merchant bar. Danieli's rolling technology delivers tight tolerances and high surface quality at full production speed.

3 Energy Efficiency

By eliminating intermediate reheating between casting and rolling, MIDA reduces energy consumption by up to 45% compared to conventional mini-mills, translating to lower operating costs and reducing grid demand.

The MIDA architecture delivers measurable benefits over conventional steelmaking across energy, footprint, emissions and product flexibility.

Key Technology Advantages

Compact Footprint

The integrated layout requires significantly less land than a traditional steel plant, making it idea for regional deployment in communities like Collie without requiring massive greenfield development.

Lower Carbon Emissions

EAF based steelmaking from scrap produces a fraction of the carbon emissions of blast-furnace methods. Combined with MIDA's energy savings, the Collie plant will be the lowest emission steel facility in the Asia-Pacific.

Product Flexibility

Danieli's modular rolling technology allows rapid changeover between product sizes and grades enabling the plant to respond to market demand without costly retooling.

First in Australia

Pioneering MIDA Technology on Australian Soil

Generation Steel's Collie facility will be the first Danieli MIDA plant in Australia, joining a select group of installations worldwide. This positions Western Australia at the forefront of advanced steelmaking technology, demonstrating that world-class manufacturing can be built in regional communities.

Danieli has deployed MIDA technology across Europe, the Middle East and America with each installation proving the platform's reliability and efficiency. The Collie deployment benefits from decades of refinement and Danieli's ongoing engineering support, ensuring the plant meets the highest international standards from day one.

Automation & Digital Control

The MIDA platform incorporates Danieli's Q3 Intelligence automation system, providing real-time process monitoring and control across every stage of production. Operators oversee the entire melt-to-product cycle from a centralised digital control room, ensuring consistent quality and maximum through put.

Advanced sensors, predictive analytics, and machine-learning algorithms continuously optimise furnace power, casting speed, and rolling parameters.
