Abstract

1. A coreless induction furnace comprising a crucible (1) of a refractory material, an induction coil (2) disposed on the outside of the crucible (1) and a helically wound elektrode (15, 16) set in the crucible wall for checking the crucible (1) for the melt (3) penetrating cracks (9), characterized in that the electrode (15, 16) is formed with the same pitch as the windings of the induction coil (2).
