The EDGE furnace is recognized as the most flexible option within the Electric Arc Furnace (EAF) family, offering unparalleled adaptability in layout utilization and raw material feeding. It is designed to accept a diverse range of metallic mixes, allowing for up to 60% hot metal and 100% Direct Reduced Iron (DRI), whether hot or cold. This capability ensures that the EDGE furnace can deliver exceptional productivity levels in a fully automated environment, making it a preferred choice for modern steel manufacturing.

Surrounding by modular solutions the furnace is powered by cutting-edge electric and hydraulic technologies.

By meeting the rigorous demands of contemporary steel producers, the EDGE furnace plays a crucial role in advancing green steel production initiatives. Its design and operational features are tailored to support the transition towards more environmentally friendly practices, ensuring that steel manufacturers can achieve their productivity goals while minimizing their carbon footprint. As the steel industry continues to evolve, the EDGE furnace stands out as a key player in the pursuit of innovative and sustainable steelmaking solutions.

ALLCHARGE represents a significant advancement in electric arc furnace technology, specifically designed for the continuous charging of scrap without the necessity of preheating. This innovative approach not only meets but exceeds current and anticipated environmental regulations, ensuring that productivity and safety are not compromised. By avoiding scrap preheating, ALLCHARGE effectively limits the emissions of harmful substances such as dioxins, volatile organic compounds (VOCs), and carbon monoxide (CO), thereby promoting a healthier production environment.

The flat bath operation of ALLCHARGE is a key feature that contributes to lower nitrogen oxides (NOx) emissions, which is crucial for reducing the overall environmental footprint of steel production.

By decoupling the scrap conveyor from off-gas suction, the ALLCHARGE design enables the charging of 100% DRI from the roof.

In summary, ALLCHARGE not only enhances the efficiency of electric arc furnaces but also aligns with global sustainability goals by minimizing emissions and reducing the impact on the power grid.

The SHARC (Shaft Arc Furnace) stands out as the most efficient scrap preheating design available for electric arc furnaces, revolutionizing the steel production process. Unlike conventional systems that typically employ a single asymmetric shaft for preheating, the SHARC is ingeniously designed with two vertical preheating shafts. This dual-shaft configuration allows for the entire cross-section of the furnace to be utilized for energy transfer, significantly enhancing the efficiency of the melting process.

The symmetrical shape of the SHARC furnace, combined with the integration of advanced DC high-current technology, plays a crucial role in optimizing energy usage. This innovative design ensures that hot exhaust gases have a longer retention time in contact with the scrap, which is essential for effective preheating. As a result, the SHARC can achieve impressive energy savings of up to 100 kWh/t compared to traditional furnace designs.

These energy savings not only contribute to lower operational costs but also align with the industry's growing emphasis on sustainability and reducing carbon footprints. By maximizing energy efficiency, the SHARC technology supports steel manufacturers in their quest for greener production methods while maintaining high productivity levels.

In response to the increasing costs associated with CO2 emissions and the fluctuating prices of charge materials for the Basic Oxygen Furnace (BOF) converter process, SMS group has developed an innovative primary smelter known as CONPRO. This advanced technology integrates the functionalities of both BOF converters and electric arc furnaces (EAF), creating a highly efficient and flexible energy source combination that addresses the evolving needs of the steel industry.

One of the key features of CONPRO is its ability to operate like a traditional BOF converter, which allows for a significant reduction in the reliance on scrap or other coolants, minimizing it to about 15%. This capability is crucial for steel manufacturers looking to optimize their production processes while managing costs effectively. The system employs a top lance and side wall lances for the introduction of oxygen, enhancing the efficiency of the smelting process.

Moreover, CONPRO is designed with versatility in mind. In scenarios where molten pig iron is temporarily unavailable or its production is halted, the system can seamlessly transition to electric arc furnace mode within a single shift. This transition requires only minor procedural adjustments, ensuring minimal disruption to production. By combining the strengths of both BOF and EAF technologies, CONPRO represents a significant advancement in metallurgical engineering, enabling steel producers to adapt to market fluctuations and sustainability goals while maintaining high productivity levels.
