Energy recovery in the continuous casting process offers substantial opportunities for enhancing efficiency and sustainability within the metals industry. During the solidification and cooling phases, a significant volume of energy is extracted from the melt. This energy, however, is often dissipated and remains unrecovered, representing a lost opportunity for energy optimization. Recognizing...
The global push to counteract climate change has led policy makers to introduce stringent measures aimed at mitigating greenhouse gas (GHG) emissions. These efforts, combined with volatile energy media prices (electricity, natural gas, etc.), have intensified the search for innovative solutions to optimize energy consumption and recover residual energy from industrial processes. Key objectives...
VOLTERON™, an innovative technology developed by John Cockerill and ArcelorMittal to achieve carbon-neutral steel production through direct iron electrolysis. This process represents a significant breakthrough in primary steelmaking by employing low-temperature electrowinning in an aqueous-based electrolyte, moving away from conventional blast furnace and basic oxygen furnace (BOF) methods,...
Gas cleaning and dedusting systems are essential for any steelmaking facility, but they often face significant fluctuations in operational requirements. Emissions can vary based on different input materials or product mixes, necessitating adjustments in the dedusting system’s operation. Manual optimization by operators is challenging due to fluctuating operating parameters, and furnace...
The transition toward a low-carbon, sustainable industrial ecosystem requires innovative solutions that maximize resource efficiency and minimize environmental impact. This study presents EnVisA, a research project funded by Vinnova, Sweden, focused on optimizing the utilization of process gases from steel production through advanced AI-driven tools. Despite the high calorific value of these...
Water consumption and wastewater disposal are critical challenges in the steel and metallurgical industries. Conventional reverse osmosis (RO) systems, widely used for producing demineralized water in cooling circuits, generate a concentrated waste stream (25-50% of feed water), which requires disposal due to high levels of calcium, magnesium and other contaminants.
At Contec Industry,...
The project involved a revamping of the EAF furnace at the steelworks department, including the construction of a new primary flue gas circuit and the installation of a closed-loop system for heat recovery.
This recovered heat is transferred to the district heating network via 1.2 km of newly installed pipelines, connecting the steel plant to its central heating facility.
As a result, the...
A key factor to pursue the “green steel” concept, is not only the emissions reduction and the lowering of the carbon footprint of the steel plants, but also the optimization of the energy consumption.
This optimization passes, of course, primarily through the direct reduction of the energy consumption, but can be pursued also through the recovery of waste energy. In steel making plants, the...
