At the end of 2017 Hydro Aluminium Hamburg, which is a subsidiary of Hydro Norsk Group, awarded a contract to Danieli Service to study and carry out the upgrading of two existing grease-lubricated slipper-type spindles for the hot-rolling mill at that location.
The new spindles, weighing approximately 35 tons each, are for the first time equipped with a fully integrated online torque measurement (TMS) and pads temperature control device.
These slipper-type spindles are also equipped with the newest air-oil lubrication system, providing improved service life of +30% and reduced operating costs of -40% (estimated for 10 years duration) while significantly lowering the environmental hazard by-5000 kg/year associated with the existing total-loss grease system.
The mill shutdown is scheduled during Christmas 2018.
The customer has confirmed its satisfaction about the on-time manufacturing and performance of Danieli.
