Definitions

  • the invention relates to a cooling plate as part of the furnace wall metallurgical furnace, in particular a melting furnace or shaft furnace, which consists of Copper or a copper alloy exists and is penetrated by coolant channels.
  • Cooling plates made of copper show in Inside, for example, coolant channels generated by mechanical deep drilling which run essentially parallel to the furnace wall.
  • the invention is based on the object of a Provide cooling plate that is clear across all operating situations has improved dimensional stability, so that longer service life is possible become.
  • the invention proposes the inside of the furnace to provide the facing side of the cooling plate with at least one coating, which has a lower thermal conductivity than the copper base material.
  • the core of the invention is therefore the undesirable changes in the cooling plates to reduce by reducing the thermal load on the cooling plates becomes.
  • the cooling plates are coated with a suitable coating on the Provide plate side facing the furnace interior.
  • This coating can be constructed from one or more layers, wherein the individual layers also have different compositions can.
  • the coating or the coatings is or are preferably by a thermal spray process, such as. B. plasma or flame spraying applied.
  • At least one of these layers functions as a Insulating or thermal insulation layer that has a lower thermal conductivity than has the copper base metal.
  • the thermal conductivity of the coating should be less than 320 W / (m • K). In the event that a particularly strong thermal insulation effect is desirable, the thermal conductivity can be less than 10 W / (m • K).
  • the thermal barrier coating can preferably either be metallic or from a Metal-non-metal connection exist. On the other hand, the thermal barrier coating also from a mixture or combination of a metal and a metal-non-ferrous metal compound be composed.
  • the thermal barrier coating can be made from a material based on zirconium oxide be built up, this expediently additions of yttrium oxide contains.
  • a coating with a different composition can be used as the base layer be the liability of the actual insulation layer or the Insulation layer system on the base body improved, e.g. an MCrAIY coating, where "M" is a metal, e.g. Fe, Ni or Co or a combination of these elements means.
  • the thickness of the entire coating is advantageously in the range of 0.1- 1.5 mm.
