It has been known that approx. 7% emissions of CO2 arises from the steel industry sector. Hence, many steel companies are trying to develop the electric arc furnace (EAF) and/or electric smelting furnace (ESF) steelmaking processes instead of blast furnace (BF) and basic oxygen furnace (BOF) integrated routes by employing high amounts of hydrogen gas direct-reduced iron (H2-DRI) to mitigate...
The Electric Smelting Furnace (ESF) process represents a promising route for sustainable ironmaking by enabling the production of hot metal and slag suitable for steel and cement industries. A critical requirement for steel plant integration is achieving hot metal with a minimum carbon content of 3.0–3.5 wt% and controlled silicon levels (~0.4 wt%), while simultaneously producing marketable...
Electric arc furnaces (EAFs) play a very important role in modern steel making by offering both an environmental and operational advantages over blast furnaces. An important gain by EAF utilization relies in lower carbon emission, potentially a zero-carbon footprint when relying on renewable energy sources. Moreover, EAF offers greater operational flexibility and higher energy efficiency...
Technological advances in steel production have greatly contributed to industrial growth, yet the steelmaking process still faces a critical challenge: the emission of large amounts of CO₂. Achieving carbon neutrality and transitioning toward a sustainable steel industry require a fundamental shift in production methods that can sustainably reduce CO₂ emissions. In this context, hydrogen-based...
In the course of industrial decarbonization, the substitution of gas burners in industrial furnace systems is becoming increasingly important. All-electric plasma torches offer a viable alternative for retrofitting existing systems. These can be implemented without requiring a complete system overhaul.
Both electrode and electrodeless plasma systems are used. Electrodeless systems operate...
Steel industry is currently undergoing a significant transformation, driven by the need to reduce greenhouse gas emissions and move towards more sustainable production methods. Hydrogen-based direct reduction of iron (H-DRI) is a promising alternative to traditional carbon-based reduction methods. The integration of hydrogen-based reduction technologies with electric arc furnace (EAF)...
