Slitting line for ultra thin gauges

In 2012, BWS decided to invest in a slitting line capable of cutting very thin strips of thicknesses down to 20 mu m at high precision into slit strip of 4 mm width or even less. BWS - Philipp Boecker + Wender Stahl GmbH & Co. KG - operates a cold rolling mill with a logistically integrated service centre for the production of stainless steel and carbon steel strips. After two and a half years of operation at BWS in Iserlohn, the design of the slitting line has proved highly successful. The line meets all the specifications stipulated in the contract with hpl-Neugnaden-felder Maschinenfabrik - a German engineering company specializing in the design and manufacture of plant and equipment for the processing, finishing and handling of strips made of steel, stainless steel, coated metals and special metals. The line cuts coils of up to 9 t weight and 2,000 mm diameter. The very thin coiled strip may be up to 40 km long. For efficient processing of such strip lengths, the line has been designed for very high cutting speeds. So far, the line has been operating without any unscheduled downtime.
