SynopsisA state-of-the-art steel scrap processing plant by Danieli Centro Recycling is now operational at Acciaieria Arvedi in Cremona, Italy. This high-performance plant handles nearly one million tons per year of light-to-medium iron grades and even sheared light demolition scrap. It produces high-density quality products that enhance Electric Arc Furnace performance while reducing the carbon footprint. The plant features advanced technology for efficiency and cleanness, including a patented variable-speed drive system and ferrous/nonferrous separation capabilities.ArticleIn a groundbreaking development, the Danieli Centro Recycling steel scrap processing plant at Acciaieria Arvedi, situated in Cremona, Italy, has been inaugurated. This cutting-edge facility marks a significant stride in the realm of steel scrap processing, boasting the capacity to handle nearly one million tons annually of light-to-medium iron grades of scrap, including sheared light demolition scrap.The primary objective of this state-of-the-art plant is to produce a high-density quality product, ensuring optimal performance for Electric Arc Furnaces (EAFs). This encompasses optimizing yield, reducing power consumption, and shrinking the carbon footprint, a trifecta of sustainable benefits.At the heart of this operation lies a formidable 7000-Hp shredder, complemented by a robust 30-meter-long industrial-strength steel belt conveyor that tirelessly supplies this powerhouse. What sets this facility apart is Danieli's patented variable-speed drive system (inverter), which slashes electrical power consumption by up to 20% compared to conventional systems, aligning with energy efficiency goals.Furthermore, a Danieli-patented noise and vibration analysis system serves as a vigilant guardian, automatically identifying unshreddable scrap pieces. This triggers the reject door's automatic control, ensuring the uninterrupted efficiency of the operation.Maintenance is a key aspect, and the plant boasts a dedicated system that monitors component wear and tear, offering timely replacement suggestions to maintain peak performance.A ferrous downstream line takes center stage, separating steel from nonferrous metals with the aid of high-efficiency cascade air and magnetic systems. This results in cleanliness levels nearing 100%, preparing the scrap for EAF input.Additionally, an offline nonferrous separation line enables the recovery of valuable materials like zorba and zurik for resale, adding an extra layer of sustainability to the process.Upstream from the shredder, an 850-kW pre-shredder plays a crucial role in preliminary pre-shredding and processing of heavy bales. This not only reduces power consumption but also minimizes wear and tear within the shredding chamber.ConclusionThe Danieli steel scrap processing plant at Acciaieria Arvedi represents a leap forward in sustainable steel production. With its advanced technology and commitment to efficiency and cleanliness, it promises to enhance the performance of Electric Arc Furnaces while significantly reducing the carbon footprint. The plant's innovative features, including a patented variable-speed drive system and meticulous scrap separation, underscore its dedication to environmentally responsible steel production.
