<p>To make the receiving space of the casing of a furnace variable, so that it can be adapted to the various volumes that are required for different feedstocks (light scrap, heavy scrap) to achieve the tapping weight envisaged for the furnace, the cylindrical upper part of the casing (102) includes a first, lower cylindrical portion (105) and a second, upper cylindrical portion (106), one of which engages over the other and is formed in such a way that it can be displaced telescopically in relation to it by at least one lifting device (21/1, 21/2).</p> |
