BOOSTING PRODUCTIVITY AND ENERGY SAVINGS AT KROMAN CELIK’S EAF (TURKEY). - MORE | Innovation in Steelmaking

BOOSTING PRODUCTIVITY AND ENERGY SAVINGS AT KROMAN CELIK’S EAF (TURKEY). - MORE | Innovation in Steelmaking: KROMAN CELIK  located in Gebze Osmangazi region (Turkey) is a producer of reinforcing bars and wire rods. Its total annual production exceeds 1.3 million tons. Since 2010, their EAF has been operating with a complete MORE sidewall injection system and DANIELI Q-REG electrode regulation with excellent results. In July 2016, KROMAN CELIK chose to upgrade their 150 ton (165 ton) EAF with the state of the art DANIELI Q-MELT process control and with the latest MORE side wall injection technologies with the aim to: improve the EAF productivity reduce operative costs Main EAF data: Furnace type DANIELI EAF EBT Tapped steel weight 150 ton – 165 ston Hot heel weight 25 ton – 27 ston Annual Production 1.300.000 tpy – 1,430,000 stpy Transformer nominal rating 140 MVA Power supply type AC   The Q-MELT is DANIELI’s latest development.
