Hoesch Hohenlimburg awarded Danieli Transmissions an order for the design and supply of new gearboxes, safety couplings and latest-generation oil-lubricated spindles to deliver increased torque and power to the rolling stands in November 2014. The project was completed right on time within a nine-month period, to the full satisfaction of the customer.
One of the main challenges was to avoid making any changes to the civil works and reutilise the anchor bolts of the existing equipment. Danieli was chosen because it offered the best technical solution and was able to guarantee that the work would be done during the planned shutdown of the mill. The project was developed thanks to Danieli’s own in-house design, and included heat treatment, machining, assembly, testing, erection and commissioning under a single point of responsibility. It started with an on-site survey where laser measurements were taken, followed by the design phase with the final approval of the customer, inspection of rough parts at the plants of sub-suppliers, quality certification and regular inspections by the customer at Danieli workshops to evaluate job progress. The machines were then tested at Danieli, with final acceptance, erection and commissioning performed during the scheduled shutdown.
Production started regularly on Sunday night respecting the required performances.
