Hasçelik is one of Türkiye’s leading manufacturers of special steel with a total of five manufacturing plants and other locations worldwide.
The new line will comprise Consteel Electric Arc Furnace (EAF) equipped with a Consteerrer electromagnetic liquid steel stirring system, a ladle furnace and a twin vacuum degasser. All units are linked and governed by an extensive, state-of-the-art automation system to optimise the whole process and guarantee high quality steel grades.
The unit selected by Hasçelik will be the first continuously charged EAF in Türkiye and will allow the steelmaker to utilise the inherent 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 heart of the system is the new Consteel Evolution based on a full-platform EAF with single-point roof lifting system, a combination that brings the benefits of energy efficiency, reduced workforce, increased reliability, improved productivity and reduced environmental impact.
The new Consteel furnace will be equipped with Consteerrer, a technology jointly developed by ABB and Tenova as part of an exclusive global partnership agreement. 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 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.
“In light of rising commodity and energy costs as well as a greater focus on sustainability, process efficiency is more important than ever” said Zaeim Mehraban, Global Sales Manager, Metallurgy Products at ABB. “Using the unique and proven ABB ArcSave-based electromagnetic stirring technology found at the core of Consteerrer, Hasçelik will be able increase productivity and energy efficiency in their electric arc furnace process and accelerate financial gains as well as progress to sustainability goals.”
With production facilities in İstanbul and Konya and a total of nine warehouses in seven provinces, Hasçelik Sanayi ve Ticaret A.S. produces and supplies hot-rolled special steel and cold-worked special bright steel and sells and distributes seamless pipes. It is the flagship in the Faydasiçok Holding group of companies and comprises bright steel production facility Hasçelik Cold Processing Center with an annual production capacity of 170,000 tons and Hasçelik Special Steel Rolling Mill with a production capacity of 300,000 tons per year.
“With this project, Hasçelik is investing to increase its competitiveness within the market of high steel grades” added Davide Masoero, Tenova Area Manager Europe Electric Arc & Ladle Furnace. “Scrap characteristics in terms of purity and density are, in fact, worsening and the Consteel technology is fundamental to maintaining high quality production.”
