WIRE rod rust is no longer an alarming phenomenon, since the introduction of the Smooth-Brush (SB) wire rod green and dry cleaning system. Installed in-line after a simple rod reverse bending descaler, the SB system removes excess rod scale and rust, converting over 95 per cent of rod scale into useful micro-abrading pads, providing efficiency and simplicity in rod dry cleaning applications, H/C and L/C, including 0.98%C. scale provides, in-line, an extremely receptive about 5-micron size texture enabling powder lubricant to be chemically and mechanically interlocked to the rod surface, forming a hard and consistent anti-wear and anti-friction conversion coating that is found to perform comparably to or better than zinc phosphate. This achieves in-line direct drawing from mechanically descaled uncoated bare rod, at virtually zero energy consumption and zero maintenance cost, in a totally green and dry application.

Special crosshead for special products Low-smoke zero-halogen material is commonly used for a wide range of products, such as low-voltage power cables, automotive cables and premises cables. This material is special with regard to its properties, since it only allows for low-temperature processing. Extrusion crossheads typically run at high temperatures and high pressure, which is why a special solution is required for the LSOH material. Rosendahl’s RX 40 F.1.0 extrusion crosshead is designed to run high output at low pressure to ensure safe and adequate handling of highly filled materials. The precise match of the crosshead and its tools allow for low shear rates and stable processing at lowmass temperatures. The RX 40 F.1.0 is a single-layer extrusion crosshead that is easy to both assemble and disassemble. Maintenance is also kept very simple and easy. It is very user friendly and most importantly it meets the material’s special requirements to achieve best results on the final product. RosendahlNextrom – Austria Website : www.rosendahlnextrom.com

Rod and wire cleaning by SB brushing system

The SB rod cleaning is used in demanding wire drawing applications, including spring wire, plating wire, galvanised wire, PC strand wire, Al clad wire, cold-heading wire, CO 2 welding wire, etc. The SB dry cleaning system replaces costly operations in wire rod cleaning processes (including acid and other aggressive wet chemicals), generating substantial cost savings, environmental benefits and improvement of productivity.
