Materials & Services segment: SMR de Haan improves the corrosion protection of steel strip

At present, a total of up to ten grams of oil per square meter of strip are applied as corrosion protection for steel strip prior to transport and storage or for cold-working in the stamping shops of the automotive industry. Customers in the automotive industry are looking for ways to achieve a sustained reduction in the volume of oil per square meter with a view to reducing costs and achieving a further optimization of the overall production process. The target is an amount of less than three grams per square meter in future. This means less than one gram per square meter can be applied in some of the individual oiling steps. SMR de Haan GmbH, Oberhausen/Germany, has developed a new electrostatic oil coating system which enables this target value to be bettered in a reliable process.

The SMR oiling system is currently being used in the new inspection lines at Thyssen Krupp Stahl AG in Duisburg-Beeckerwerth and Bruckhausen, Germany. In addition an electrolytic coating machine, a slitting machine and a blank oiling machine also employ this technology. Applications for the new SMR product are not restricted to the steel and automotive industries, however. It can be used wherever oil is employed as a separating agent, for instance in the manufacture of textiles and foodstuffs. The latest order being handled by SMR de Haan for a major German automobile manufacturer is particularly demanding. This involves applying corrosion protection to unmachined body blanks for sea transport through various climate zones. The oil film has to provide even coverage of every corner of the complex-shaped parts and be sufficiently thin so that onward processing at the destination is not impaired.
