Slovakian steelmaker U.S. Steel Košice has placed a order for the supply of an annealing and coating line (ACL) for dynamo steel strips to Tenova LOI Thermprocess, a leading global supplier of heat treatment lines and furnaces.
According to Tenova, the plant bears the internal name of Dynamo-Line no. 4 and will meet the highest requirements for the production of non-grain oriented electrical steel. The contract includes the engineering, to a large extent the turnkey delivery of all equipment as well as the supervision of the assembly and commissioning including training.
Tenova, part of the Techint Group and alongside other companies until the Techint umbrella, designed and delivered the entire line and was chosen by US Steel Kosice for several reasons: The multiplicity of references for comparable facilities, the short realization time and the mathematical model were of crucial importance.
Techint group companies – Tenova LOI Thermprocess and Tenova Italimpianti, suppliedthe complete annealing and coating line (ACL) including the furnace, the entire strip handling and chemical processing with drying oven following the coil coating, the associated electrical, instrumentation and control technology including the automation system.
US Steel Košice is a wholly owned subsidiary of US Steel Group headquartered in Pittsburgh in the USA. It is a fully integrated metallurgical plant and one of the largest industrial companies in the Slovak Republic. In addition to the production of thin sheet, ultra-fine sheet and galvanised strip, non-grain-oriented electrical steel sheets have been produced for more than 30 years. The company is undergoing extensive modernization in order to improve product quality. One of the measures is the dismantling of two outdated annealing and coating lines and at the same time the construction of the new annealing and coating plant.
Between 2000-2019, Tenova received a total of 60 orders for heat treatment systems for electrical steel, 34 of which are completely new installations.
