Method for determining amounts of inoculant to be added to a cast-iron melt in a specific casting process, comprising the steps of: -providing a first sample holder(1) and a second sample holder(2) each having a thermocouple(3, 4) which is connected to analysis equipment (5); -filling each sample holder(1, 2) with an amount of molten iron; recording a first cooling curve during solidification of the iron in the first sample holder(1) and a second cooling curve during solidification of the iron in the second sample holder(2); characterised in that one of the sample holders, before being filled with molten iron, has a predetermined amount of inoculant placed in it which represents the inoculant saturation level in the specific casting process, the amount of inoculant to be added to the melt in the specific casting process being determined on the basis of the difference between the lowest eutectic temperature(TElow) on the first cooling curve and the lowest eutectic temperature(TElow) on the second cooling curve. |
