摘要： Disclosed is a container for the thermal analysis of cast iron that enables a reduction in the amount of tellurium used in thermal analysis. By forming a plurality of fine spaces in the interior of a base plate (12) and sidewalls (11), thermal insulating properties are maintained in the base plate (12) and the sidewalls (11) and the temperature of a sample of the cast iron melt placed in the interior of the container (1) is prevented from cooling down. As a result, even if the amount of a sample supplied for thermal analysis is reduced, the speed by which the temperature of the sample drops is suppressed, and a constant temperature is maintained by the heat from the latent heat of solidification. Accordingly, the amount of tellurium used in thermal analysis can be reduced by reducing the amount of the sample supplied for thermal analysis.

摘要： Methods for inspecting the content of structure modifying additives in the molten bath of cast iron and chilling tendency of flaky graphite cast iron by means of a thermal analyzing test and a sampling vessel to be used therefor. The method consists of the steps for: obtaining a first cooling curve of the molten bath of cast iron using a first sampling vessel, obtaining a second cooling curve of the molten bath using a second sampling vessel in which small amounts of tellurium are contained, and comparing the first cooling curve with the second cooling curve.
