Herkules and the Salzgitter Flachstahl GmbH can look back on a long and successful relationship. The customer was impressed with the quality and precision of Herkules roll grinding machines during the modernization of their roll shop in the hot rolling mill in the early 1990s. A trusting partnership began that is being continued today.
The desire for innovation and the latest technology drove Salzgitter Flachstahl GmbH in 2016 to invest once more in its own roll shop. Herkules can meet the requirement for the roll grinding machines, to be able to use CBN technology, like no other supplier. Already in 2012, Herkules was able to successfully machine rolls for the steel industry using CBN technology at Voestalpine. At a very early stage, such a significant innovation leap over the competition was achieved. The know-how and precision of the machines ultimately convinced the customer this time as well.
Nevertheless, Salzgitter Flachstahl GmbH initially decided on a work roll grinding machine from the competition. Even before this machine was assembled, the customer additionally ordered a "brother machine" from Herkules for reasons of comparability. After installing and comparing both machines, Herkules kept the customer's trust. Salzgitter commissioned Herkules for two more machines, a combined support and work roll machine and another work roll machine for their cold rolling mill. After the direct comparison, the "total cost of ownership" seems to have been decisive.
Equipped with Herkules MACHtechnology as well as the superior HCC/KPM control and measuring systems, such as the Eddy Current and Ultrasonic roll testing systems and automatic roughness measuring methods, the Herkules roll grinding machines not only offer state-of-the-art technology, but also maximum precision and performance. Thanks to the various technologies from Herkules, the Salzgitter hot rolling mill is perfectly equipped for roll processing. Thanks to the Monolith™ design, the machine bed absorbs vibrations that occur, guaranteeing homogeneous roll surfaces. In addition, the inherently rigid construction is thermostable and requires no foundation. A clear advantage for the customer.
The package, consisting of Herkules machines, control and inspection technology and grinding wheels by our partner Mach Rotec, guarantees reliable and reproducible grinding results. Herkules MACHtechnology saves a considerable amount of time due to greater stock removal rates and shorter machining times. The service life of the rolls is significantly improved thanks to the optimization of the stock removal.
Absolutely homogeneous, flawless surfaces covering the entire roll and high energy efficiency are additional advantages. Rolling mills need constantly better rolls with comma and cloud free surfaces. With the Herkules MACHtechnology we offer you a perfect solution concept.
