Abstract (en)

[origin: EP0345542A2] Cold smelt crucible for the smelting of small quantities of metal in suspension. The crucible contains the crucible dish in its upper part and can be flanged with its base part to a vacuum line or to a corresponding vacuum apparatus. The crucible dish consists of appropriately shaped wall segments (1) which are separated from one another by slots and in which cooling channels (7) extend. Feed lines are introduced into these, starting from the base part (2). The coolant is introduced and drawn off via the base part (2). The object of the invention is to provide a crucible which is easy to repair, with a cooling system improved in comparison with the state of the art. This is achieved by means of an upper part formed from individual wall segments (1), by an intermediate part consisting of the discharge pipes (8, 9) and by a base part (2), in which are arranged annularly the coolant lines, from which the feed and discharge pipes (9) project out of the base part (2) in an annular arrangement. <IMAGE>
