The new sandpaper descaling machine

Complete rod preparation portfolio for advanced wire cleaning

The machine has one or two 300mm-wide sanding belts, with rod wire guide rollers and integrated line speed feedback to avoid the risk of over-sanding if the line stops. The device is also equipped with features such as belt tracking control, synchronisation to line speed, and individual drives for each flyer and sand belt to allow full rpm flexibility. Lämnea Bruk’s sandpaper descaling machine is suitable for low- to high- carbon and stainless steel wire. The rod preparation equipment is manu- factured entirely in the company’s own workshop in Sweden, and is designed, manufactured and tested according to European safety standards.

The mechanical brushing system is fitted with an intelligent brush pressure detection system for improved cleaning results and extended brush lifetime. The high-pressure water jet is a compact descaling system that 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 from carbon steel and stainless steel wires in a three-step process: loose particles are removed from the surface with hot water, the lubricant carrier applies a wet coating, and the rod is dried. The most recent launch in Lämneå Bruk’s rod preparation portfolio is the second generation of the sandpaper descaling machine.

Lämneå Bruk’s rod preparation portfolio includes five machines designed for continuous, in-line mechanical descaling of wire rod. Mechanical descaling is an environmentally friendly method of rod cleaning, so the machines have a minimal environmental footprint and facilitate efficient, space-saving in-line rod cleaning for wire prepared for the next production steps. The descaling system consists of a four- or six-sheave scale breaker, a four-pair brushing unit, a new sandpaper descaling machine, a water jet and the Candocoat cleaning and coating machine. The reversed bending descaler, suitable for low-high carbon rod preparation, 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.
