The FOEN® air knife system is well-known as the most advanced galvanising system for the production of all steel grades used in the automotive industry with highest demands on surface qualities. The first integrated solution of an air knife in combination with a strip stabilisation system was also executed with the FOEN DEMCO® system. As a subsequent improvement of this solution the FOEN DEMCOJET® was recently developed minimising the distance between air knife and acting stabilisation point to approx. 500 millimeters in order to achieve the best coating result. Up to now, already 12 FOEN DEMCOJET® systems have been sold in galvanising lines all around the world. The system is or will be integrated soon at first class producers of galvanised strip like Ternium, US Steel, Tata Steel, Nucor, Stelco, HBIS, CSN, voestalpine or Salzgitter.
