Hasçelik selects Tenova and ABB for new steelmaking line

steel and reduces oxygen content in the bath. The technology can be customised to match the needs of different EAFs and retrofitted on existing units. Tenova SpA www.tenova.com Hasçelik Sanayi ve Ticaret AS https://hascelik.com

The new furnace will be equipped with Consteerrer – a technology jointly developed by ABB and Tenova. Consteerrer is an application of ABB’s ArcSave® non-contact electromagnetic stirring technology designed specifically for continuous-charging EAFs. It reduces thermal losses, increases melt rate, rapidly homogenises the liquid

Tenova, a developer and provider of sustainable solutions for the green transition of the metals industry, has received an order from Hasçelik Sanayi ve Ticaret AS to install and commission equipment in a new plant in Osmaneli, Bilecik, Turkey. Hasçelik is a manufacturer of special steel with a total of five manufacturing plants and other locations worldwide. The new line will comprise a Consteel® electric arc furnace (EAF) equipped with Consteerrer® electro-magnetic liquid steel stirring system, a ladle furnace and a twin vacuum degasser. All units are linked by an automation system to optimise the whole process and ensure the quality of the steel grades. The unit selected by Hasçelik will be the first continuously charged EAF in Turkey, and will allow the steelmaker to use the flexibility of the Consteel EAF to tackle declining scrap availability and quality. The continuous charge makes the process robust to the variation of the scrap density, quality and content of volatile compounds. At the centre of the system is the new Consteel Evolution, based on a full-plat form EAF with single-point roof lifting system. This combination is claimed to provide the benefits of energy efficiency, reduced workforce, increased reliabil ity, improved productivity and reduced environmental impact. Within Consteel, the fumes from the EAF are used to pre-heat raw materials inside the pre-heating section, while the scrap is delivered to the crucible with a steady, controlled flow. With the continuity of the charge, the organic compounds developing from the non-metallic portion of the scrap get thoroughly pyrolysed and combusted within the system, ensuring the minimum possible generation of noxious substances such as dioxins and furans. The system also reduces noise and provides a safer and healthier working environment while eliminating the need for personnel operating in hazardous areas.
