Abstract

The material is more resistant to high temps and physico-chemical corrosion than Cu or ordinary steel. It may have as high an electrical conductivity as possible. The covering may be performed by coating e.g. by spraying, vacuum evaporation or plasma torch; or by application of a cap; e.g. by soldering or by explosive fixing. The covering may be an alloy, e.g. of Cu-Cr, Cu-Cr-Be, or Zr. The tuyere may be water-cooled.
