    • This invention relates to a method for continuous production of a self-baking carbon electrode in direct connection with the smelting furnace wherein the electrode is consumed. Blocks of a first unbaked carbonaceous electrode paste is supplied to a curing chamber arranged at the upper end of the electrode, which curing chamber is open at its top and at its bottom and has an inner cross section corresponding to the cross section of the electrode which is to be produced, said blocks of the first unbaked carbonaceous paste having a smaller diameter than the inner diameter of the curing chamber, supplying a second particulate unbaked carbonaceous electrode paste to the annulus between the curing chamber and the blocks of the first unbaked carbonaceous electrode paste, said second electrode paste comprising a binder which cures at a lower temperature than the first carbonaceous electrode paste, heating and curing the second carbonaceous paste by means of heating means arranged on the curing chamber. The second carbonaceous electrode paste thereby forms a cured shell about the central blocks of the first carbonaceous electrode paste. The central unbaked blocks of the first carbonaeous electrode paste is then baked into a solid carbon electrode together with the cured shell by means of the heat generated in the area of electric current supply to the electrode. The invention further relates to an apparatus for production of such electrodes.

    • 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 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.
