Combinative 2Hi/4Hi skin pass mill is applied for processing varies steel type like Carbon steel, high strength microalloyed steel; with max width of820mm, thickness of 0.2-6.0mm. The mill take the 2 Hi/4Hi roll set to make sure the reducer within 0.2%-15% by stretching and depressing working method.
For 4Hi mill, the mill equip with the minus/plus roll bending system results in different roll chamfer can expand the product range. The mill designing considered the easy operate requirement so that can ensure mill’s flexible operation. To meet the requirement of high work efficiency, the mill equipped with fast roll changing system and also equipped decoiler with manipulator for automotive unload sleeve and coil.
The SPM production line gets the full-closed cover around its core equipment, which can guarantee the personal safety of the operating staff, improve security and meet the stringent requirement ofGermanynoise and smoke emission regulation. The mill is provided by AC-motor with the whole capacity of 1.6MW. The designing stresses on efficient and energy saving to minimize the affect to electrical network, choose energy regeneration drive equipment with min harmonic disturbance and the reactive power compensation equipment. Use the highest efficiency motor. The automatic control system getting the most advanced real-time control function can automatically control the thickness of strip steel and elongation percentage, and with the detect device for testing strip steel shape.
Danieli Florin will provide one combinative 2Hi/4Hi SPM for Iserlohn Letmathe plant of Risse+Wilke company to replacing the present two SPM.
