Definitions

the invention relates to a casting mold for producing strands of non-ferrous metal according to the features in the preamble of claim 1.
Such a casting mold has a circumferential casting throat, which is delimited on a partial length to the outside by a circulating steel strip.
the pouring throat is cooled from inside the mold, in particular by spraying water.
the mold is used in wire making to strand liquid non-ferrous metal such as copper or aluminum, and copper and aluminum alloys, respectively. From the strands wires are then produced in downstream forming process.
the mold rotates about a horizontal axis with the endless steel belt covering the pouring throat over an area corresponding to about 3/4 of its circumferential length.
a U-shaped channel is formed by the G demkhle and the steel strip, which is open at both ends upwards.
liquid non-ferrous metal is poured into it.
the non-ferrous metal introduced into the casting channel solidifies on the outer surface during one-half to three-quarters of a turn of the casting mold and then leaves the channel at the other end as a strand.
the invention is based on the object to provide a mold in which a casting of the casting is superfluous.
a coating which is permanently connected to the casting mold is provided in the region of the casting throat, which consists of a material whose thermal conductivity is ⁇ 90 W / m * K.
the surface roughness of the coating Ra is> 1 ⁇ m.
the surface roughness Ra is> 2 ⁇ m.
At least the casting throat is made of copper or a copper alloy, the coating consisting of a material whose thermal conductivity corresponds to a maximum of 25% of the thermal conductivity of copper.
the coating consists of a metallic, semi-ceramic or ceramic material.
the coating is selected according to claim 5 preferably from the following group of materials: Al 2 O 3 , ZrO 2 8Y 2 O 3 , MCrAlY, WCCoCr or Cr 2 C 3 / Ni20Cr.
the coating preferably has a layer thickness in a range of 0.1 mm to 0.5 mm, in particular 0.2 mm to 0.3 mm.
the coating can be single-layer or multi-layer, whereby the materials of superimposed layers may differ from each other.
an adhesion-promoting intermediate layer eg MCrAlY
an intermediate layer as adhesion promoter is not absolutely necessary, but not excluded within the scope of the invention.
