The present invention relates to a metal element such as a spinner for producing a mineral wool material, preferably made of a single casting piece of metal superalloy based on nickel or cobalt,;This member is provided with suitable heating means 20 for drawing single crystals to form every single molding workpiece in the cavity 19 of the mold or container 11 and a single crystal selection A compression section 16 and a vessel 11 composed of an upper workpiece forming chamber 15 and a lower crystal forming chamber 12 connected by a starter. The single crystal is much more corrosion resistant than the same material with polycrystalline structure. On the one hand, there is the possibility of receiving high strain at high temperatures before breaking the creep for 1,000 hours, and on the other hand the high ductility distributes the stresses evenly in the material so that the large ductility avoiding the stress peaks cooperate The spinner of the present invention is most suitable for operation at high temperatures for reasons desired in the fiberization of rock wol such as basalt by internal centrifugation.
