The resultsshow that the enerey consumption may be reduced by 41% by using this technique.During the semi-lining ESR under normal atmosphere, there is no evident loss ofactive metal elements, while the contents of O, N and S can be effectively reducedto 10ppm in superalloys GH49 and GH37. The ingot solidified along its axis andhas a compact microstructure. The secondary dendrite arm spacing of the semiliningESR ingot is about 1/3 shorter than that of tbe general ESR ingot.
