って知る。2. Description of the Related Art In order to examine the structure of a molten metal in advance before a furnace in order to cast a casting such as cast iron or aluminum and an aluminum alloy (hereinafter referred to as "light metal") as a metal, a sample of the molten metal is generally provided with a temperature sensor. The cooling curve is obtained by a temperature measuring device.

As in the present invention, there is also a sample container for thermal analysis that can be immersed in the molten metal and directly supply the molten metal to the sample chamber of the sampler to fill the sample chamber with the molten metal. It is manufactured by filling the hardening material, curing it by heating, etc., and then removing it from the mold.However, since there is a part where the internal path is bent, the center of the sample chamber is manufactured so that this part can be manufactured. Is divided into two parts symmetrically in the vertical direction with respect to an axis passing through the temperature sensor. After the temperature sensor is assembled, an adhesive is applied to the divided surface, and the two parts are bonded and integrated.

激に低下する恐れがあり、正しい冷却曲線を得ることが
できないという問題がある。When the sample is indirectly poured into a sample collection container for analysis using a ladle or a ladle, the temperature of the molten metal taken out of the furnace rapidly drops due to the influence of the ambient temperature. There is a problem that there is a fear that a correct cooling curve cannot be obtained.

題がある。[0006] Further, even in a container in which the molten metal is immersed in the molten metal and poured directly into the sample chamber, the central part of the sample chamber is divided into two parts symmetrically in the vertical direction with respect to an axis passing through the temperature sensor, and the divided surface after the temperature sensor is assembled. If the adhesive is applied and bonded together, the adhesive will be mixed into the collected sample and the correct cooling curve will not be obtained, or the adhesive will be sealed depending on the adhesive application conditions on the divided surface. There is a problem that the molten metal may leak due to insufficient effect, a cooling curve may not be obtained due to an insufficient amount of molten metal, or a worker may be dangerous due to the leaked molten metal.
