The machine consists of:

  • 1 cleaning chamber (wet / dry cleaning)
  • 1 large wet coating chamber
  • 1 drying chamber (incl. cold and hot air blowing nozzles)
  • 2 stainless steel tanks in one housing (capacity approx. 180/260L ) with 2 wet-pit pumps, 1 stirrer and 6 heating elements

The Cleaning and Coating Machine has firstly the purpose to rinse out the rests of the mechanical descaling through a hot fluid and to blow off the wire by compressed air.

The water in the cleaning tank is heated up to 90°C by means of 2 heating cartridges. Through a circulation pump and 2 cleaning nozzles the water is charged on the surface of the running wire and rinse out the rests and dust of the wire. Afterwards the wire goes through a cold air nozzle to blow off final residues and to prevent the water for rinsing to be dragged to the coating chamber. The water in the rinse and the cold air area flows back to the tank. The dust falls down in the sedimentation tank and will additionally be cleaned through a bar magnet. The bar magnet and the funnel tube can be handled at the operation side.

The following wet coating chamber has the purpose to coat the cleaned wire with a liquid lubricant carrier. All components being in contact with the coating solution are made of stainless steel. The wire is fed into the coating chamber through a guidance die.

The coating is effected in three working steps.

1.                   working step:                      applying a liquid lubricant carrier

2.                   working step:                      blow-off of the wire with cold air to achieve a thin and uniform lubricant carrier film.

3.                   working step:                      drying of the wire by means of a hot air system.

After this work steps the wire will be fed to the outlet of the machine and will be given to further aggregates.

The cleaning unit as well as the coating unit are equipped with one tank each made of stainless steel which contains the cleaning solution or the coating solution respectively. The capacity is approx. 180/260 liter. Two wet-pit pumps deliver continuously (40 l/min) cleaning and coating solution into each chamber. The capacity of the coating chamber is limited by an overflow design. The exceeding solution returns to the tank. The continuous operation of a stirrer guarantees a steady concentration of the coating solution. The coating solution is heated up by four heating cartridges to the operating temperature of 95°C, the cleaning solution by two heating cartridges. By means of a temperature feeler a temperature control continuously checks the actual with the nominal temperature and if necessary activates the heating cartridges. The availability of sufficient coating solution is controlled by a level control. A signal lamp indicates if the level is to low.
