Zhejiang Yuxin Steel's new Danieli Zerobucket EAF with Tornado continuous scrap-preheating system has received final acceptance. The patented variable-geometry system automatically adjusts conveyor cross-section for optimal fume control, achieving 70 kWh/t energy savings versus conventional charging and 10 kWh/t over static preheaters. The technology enables flexible scrap usage while minimizing carbon and NOx emissions, establishing a new benchmark for efficient, low-emission EAF steelmaking with short payback period.
