Abstract
A device for the production of a metallic strip using a rapid solidification technology is provided. The device includes a movable heat sink with an external surface onto which a melt is poured and on which the melt solidifies to produce the strip, and which device includes a rolling device which can be pressed against the external surface of the movable heat sink while the heat sink is in motion.
Claims12
A metallic strip having a nickel-based composition and having a length of at least 20 km and at least one surface with a surface roughness Ra, measured as center-line average heights, of less than 0.6 μm at a point at least 10 km before an end of the strip.
A metallic strip having a nickel-based composition and having at least one surface with a surface roughness Ra, measured as center-line average heights, of greater than 0.2 and less than 0.6 μm at a point which lies at least 20 km away from the beginning of the strip, wherein the surface with a surface roughness Ra of less than 0.6 μm is a surface solidified at an external surface of a movable heat sink.
