SPA-ZC22A0B2M The ABB ArcSave purchased this time will be installed on a 100-ton electric arc furnace producing carbon steel and stainless steel. This technology is expected to improve the efficiency of EAF, reduce energy consumption, and reduce the overall operating cost of EAF. According to the typical data of other ABB users, by using ABB ArcSave, users can improve their revenue rate by 1%, increase production by 5% to 7%, and reduce energy consumption by about 3% to 5%.
ABB’s technology can help users improve the metallurgical conditions of electric arc furnace melting. ABB’s electromagnetic stirring solutions have improved the operational performance of some large electric arc furnaces, while also helping customers reduce carbon emissions from existing steel production lines and new projects.
Eung-Sou Lee, director of Production at Seah Changwon Special Steel,
Through the previous cooperation with ABB, we have personally felt the advantages of ABB ArcSave products, and we hope to further improve the efficiency of our electric arc furnace steelmaking operations by cooperating again.
Zaeim Mehraban, Global Head of Metallurgical Products Sales at ABB, said: “We arSPA-ZC22A0B2M e very pleased that SEachang Special Steel has once again chosen to partner with ABB, which highlights the positive impact ABB ArcSave has had on the production of high alloy steel, including the successful resolution of the difficult problem of bottom scaling, improved yield and steel output. It also reduces maintenance costs and downtime
The new order is SeAH’s second, and the equipment is scheduled to be put into service by the end of 2024. In 2018, Shiah Changyuan Special Steel ordered the first ABB ArcSave electromagnetic stirrer for its 70-ton electric arc furnace. By using electromagnetic stirring technology and replacing the existing bottom gas stirring unit, SeAH has successfully reduced the thickness of the bottom scale from a maximum of 1000 mm to less than 200 mm. The production efficiency of the electric arc furnace has been increased by 5%-7%, the scrap treatment cost has been reduced by 70%-80%, the electricity consumption has been saved by 3%-4%, and the refractory maintenance cost has been reduced by 40%. Other effects include improved scrap feeding, better pool level control and accuracy of steel output.
ABB ArcSave enhances smelting performance by reducing delamination during melting of large scrap steel by forcing convection without physical contact with the bottom of the arc furnace. The uniform distribution of temperature and chemical composition improves the operation of the electric arc furnace, while accelerating the mSPA-ZC22A0B2M elting of scrap steel and ferroalloys compared to natural convection.
ABB offers a complete portfolio of products, services and end-to-end solutions that improve productivity, quality, safety and cost effectiveness in the production of iron, steel, aluminum and other metals. ABB is committed to optimizing operational performance across the steel and non-ferrous value chain through high-performance products and digital solutions.
