After decision taken by Stahl Gerlafingen to upgrade their Electrode Regulation System for secondary steelmaking process, AMI supplied the DigitARC^® PX3 ERS for Ladle Furnace which was delivered in May 2022, with all onsite commissioning work finished in middle 2022. Startup was carried out within the shortest possible time to minimize production downtime.

Stahl Gerlafingen, as a part of the Beltrame Group specializes in the supply of high-quality products for construction, automotive, energy and heavy industry. Their 80 Ton 11 MVA Ladle Furnace was updated with the objective to reduce electrode consumption, increasing heating rate and decrease ladle refractory wear.

Technically, a transition from Z to I-Z regulation control took place as part of the improvements done in the regulation system looking for better arc stability and reducing electrode consumption by improving control accuracy.

The interface includes a set of powerful diagnostic tools and configurable screens to control almost every aspect of furnace, this allows customers to standardize the operation process.
