Installation for the plasma remelting of the surface layer of metal ingots

摘要

The invention relates to an installation for the plasma remelting of the surface layer of metal ingots. According to the invention, it comprises, inside a leaktight cylindrical chamber 1 having orifices 29 made on its lateral walls in accordance with a number of plasmatrons 26, an ingot holder 7 to which is mechanically linked a principal alternating rectilinear displacement control 18 intended to effect the mutual displacement of an ingot 8 and of the plasmatron 26. The individual plasmatron holders are engaged through the corresponding orifices 29 and arranged below the ingot holder 7. The invention applies particularly to metallurgy. <IMAGE>
