The Mechanical Brushing System is fitted with an intelligent brush-pressure detection system for improved cleaning results and extended brush lifetime. The High-Pressure Waterjet compact descaling system uses only water, without any chemicals in the cleaning process. As no wearing occurs while cleaning the rod, the result is consistent wire quality. The Cleaning and Coating machine removes scales effectively from carbon steel and stainless steel wires in a three step process: loose particles are removed from the surface with hot water, then the lubricant carrier applies wet coating, and lastly the rod is dried. The most recent launch in Lämneå Bruk’s rod preparation portfolio is the second generation of the Descaling Sandpaper Machine.

Mechanical descaling is an environ- mentally friendly way of rod cleaning, to prepare wire for the next production steps. Lämneå Bruk has five machines in its rod preparation portfolio, designed for continuous, in-line mechanical descaling of wire rod. The descaling system consists of a four- or six-sheave scale breaker, a four pair brushing unit, a new Sandpaper Descaling machine, a Waterjet and the Candocoat Cleaning and Coating machine. The Reversed Bending Descaler is suitable for low-high carbon rod preparation, and is available in two sizes for wire diameters from 5.5 to 12mm. The design is equipped with bending rollers with solid carbide steel placed at the centre, eliminating the need to change the entire roll.
