Tenova was awarded a contract by Valbruna ASW Inc for the supply of a new Electric Arc Furnace for its facility located in Welland in Ontario in Canada. The scope of the supply includes the latest generation of the EAF unit, which will replace the existing one. Tenova will also provide the associated auxiliary equipment, the material handling system, including bins batteries, hoppers and conveyor belts, for the charging of the ladle and of the EAF and the complete automation system. The complete management of this plant will be fully automatized and integrated in the new the EAF process control system. The new EAF will guarantee thus an increase in the plant’s hourly melt shop production rate and the effectiveness and reliability in the production of high quality steel and stainless steel.
The new automation system brings several advantages, which will considerably enhance the level of efficiency of the plant. In particular, it guarantees the correct and effective execution of the working cycle in relation to the production of different steel grades. It also optimizes the working parameters and the storage of production data. In addition, the safety of the operators in the plant is significantly improved and the system complies with the most stringent safety standards.
The new EAF will be equipped with Tenova’s Digital Electronic Regulation system. TDRH 4.0 can provide a significant reduction in the electrical consumption of the EAF itself and ensures excellent arc stability. This updated version has additional features mainly dedicated to self-diagnostic, faults identification and compensation, as well as auto-calibration (self-learning) and adjustment of the regulation parameters. These functions aim to preserve the optimized electrodes regulation performances over the time.
