occur in all vessels containing melts at high temperatures. In the case of channel\nholding furnaces, the losses are determined by the melt contact surface, the bath\nsurface and the inductor idle losses. For a 120 kW inductor the inductor losses\namount to approx. 25 kW and for a 2,000 kW inductor approx. 100 kW. With opti-\nmum vessel design, the melt diameter also corresponds to the height of the melt-\ning bath, thus achieving the lowest possible contact\/bath surface with the\nlargest possible capacity. Holding furnaces can act like a \u201cthermos flask\u201d\ndepending on the heat insulation and the lining. With a 13-t crucible furnace, the\nfollowing losses must be expected: 120 kW thermal wall loss, 20 kW bottom loss,\n35 kW surface loss with closed cover, totalling 175 kW idling losses.\n<\/p>\n","protected":false},"excerpt":{"rendered":"
