摘要
Specific casting method is added into molten cast iron for measuring large quantities of inovulants in method, includes the following steps:-provide that there are thermocouple (3,4) to be connected to analytical equipment (5) for one first specimen holder (1) and the second specimen holder (2); Fill each specimen holder (1,2) and a certain amount of molten iron; The first cooling curve solidified iron specimen holder (1) is being recorded in the first and second cooling curve solidified iron in the second specimen holder (2); It is characterized by: before a specimen holder, it is being full of molten iron, inovulant with a predetermined amount is placed in the saturation degree expression particular cast technique of these inovulants, and the difference (TElow) for the lowest eutectic temperature that the particular cast process that the amount of the inovulant is added into melt determines on the basis of being is in the first cooling curve and minimum eutectic temperature (TElow) in the second cooling curve.
