Definitions

  • the invention relates to a plant for the fire metallization of small parts made of steel or cast iron according to the preamble of claim 1.
  • the invention has for its object to make the generic system for the fire metallization of small parts ready for an efficient mass production.
  • the plant according to the invention for the fire metallization of small metallic parts is characterized by high production rates.
  • the system enables the combination of the usual heat treatment processes for metal parts such as stress relief annealing, normal annealing and bright annealing with an immediately following one Fire metallization process. There is also the possibility of merely performing an annealing treatment of the parts with the system for annealing and fire metallizing metal parts.
  • the annealing treatment of the metal parts under protective gas which replaces the widely used pretreatment processes such as pickling in an acid, flux treatment and predrying, enables the parts to be optimally prepared for the fire metallization by reducing or completely degrading the parts in the surface of the parts to be metallized Materials such as phosphorus and silicon, which influence the reaction time between the metallic starting material of the parts and the liquid metal of the bath during metallization, as well as a bright annealing of the parts.
  • By switching off the interfering factors that influence the reaction time differently it is possible to achieve a uniform thickness of the metal support of the metal parts that can be controlled via the reaction time, primarily of steel parts regardless of the steel quality.
  • the system enables the use of alloy baths for metallizing, such as zinc-aluminum baths, so that metal parts with high-quality metal alloys can be produced as a support.
  • the temperature of the parts supplied to the metal bath under a protective gas atmosphere can be regulated to a certain temperature value above the temperature of the metal bath by the zone-adjustable furnace temperature, regardless of whether metallization is carried out at low, normal or high temperature.
  • This measure has the advantage that the heating phase of the parts to be coated is omitted and the radiation losses of the electrically inductively heated metal bath are compensated for, so that an increase in productivity with a simultaneous energy saving is achieved by the possible shortening of the dipping sequence of the diving baskets with the parts to be metallized .
