Tosyali orders quantum EAF and slab caster capacity

Turkish steel producer Tosyali has placed an order for second EAF Quantum electric arc furnace with a capacity of two million metric tons of liquid steel per year, and to expand the production capacity of a recently ordered two-strand slab caster to 3.4 million metric tons per year.

The new order follows an order placed in 2020, which encompassed a first EAF quantum electric arc furnace, a twin vacuum-degassing plant with oxygen blowing, and the original version of a two-strand slab caster. All plants will be erected at a flat steel greenfield project in of Tosyali in Iskenderun, Turkey. Commissioning is expected for late 2022.

The new EAF Quantum – as well as the one ordered in 2020 – are designed to handle metallic scrap and virgin materials such as HBI, pig iron in different composition and quality. The electrical energy requirement of the electric arc furnace is extremely low, mainly thanks to the scrap preheating system, but also due to many other features of EAF Quantum technology, such as FAST Tapping system, continuous foaming slag and continuous submerged electric arc (Flat bath operation).

This reduces both the operating costs and the CO2 emissions. The EAF Quantum is a highly productive furnace that will reach lowest of possible power off times. The twin vacuum-degassing plant provides further treatment and steel quality to the production portfolio of Tosyali Demir Celik.

With oxygen blowing possibility Tosyali Demir Celik steel plant will be ready to produce steel grades starting from ULC grades up to high carbon grades, peritectic grades, API grades, dual phase grades and also high strength low alloyed steel grades. The two-strand continuous slab caster will provide a capacity of 3.4 million tons of slabs per year and is able to process a wide range of steel grades.

The EAF Quantum developed by Primetals Technologies combines proven elements of shaft furnace technology with an innovative scrap charging process, an efficient preheating system, a new tilting concept for the lower shell, and an optimized tapping system. This all adds up to very short melting cycles.
