<p>The present invention relates to a method for casting molten metals, especially ferro alloys and silicon. Molten metal is continuously supplied from a tundish to a plurality of open moulds arranged along the outer periphery of at least one substantially horizontally arranged casting cylinder which is being rotated about its length axis. The moulds have a cross-section which in two dimensions corresponds to a pre-set final size of the cast metal and the length of the moulds is at least ten times larger than the largest diagonal in the cross-section of the moulds. The metal is solidified in the course of 10 to 25 seconds, and the solidified metal rods are caused to fall out of the moulds during rotation of the casting cylinder whereafter the rods are cooled to ambient temperature by natural or controlled cooling and split into final size in the third dimension. The invention further relates to an apparatus for casting metals comprising a tundish for molten metal, at least one outlet opening arranged in one of the walls or the bottom of the tundish, at least the substantially horizontally arranged casting cylinder having a plurality of moulds on its periphery, said casting cylinder being rotatable about its length axis.</p> |
