Remarks on Ansaldo measurements

• The oil has reached a max temperature of 242º C. This is about 12 º C higher than the normal value.

• It is possible to re-scale the temperature seen by the coil to a “normal” oil temperature thanks to the correlation between oil temperatures and max temperatures measured during the cycles

increase of coil temperature of 7 C every 11 C of the oil

Therefore….We can consider that the max coil temperature

for a max oil temperature of 230° C would be about 7.5 ° C less, it means a max temperature of 222 ° - 223 ° C

From Ansaldo dummy• If we estimate the error between coil and sensor in

the mould starting from the Ansaldo dummy and we apply such error to the Ansaldo’ s mould measurements during the tests we get:
