A thermoelectric device, that is a thermoelectric brick into which Bi-Te thermoelectric modules were incorporated, was prepared to convert the waste heat from founding processes into electric energy. It was applied to a casting process for manufacturing BC6 copper alloy products. A stainless vat filled with green sand taken out from the mold just after casting was placed on the thermoelectric brick. Electrical voltage generated in the brick was measured to be 1.2V at maximam when the temperature difference ⊿T between Cu plate located on the top of the brick and the edge of the cooling fin was 10K. To obtain larger ⊿T, the thermoelectric brick was brought into direct contact with the casting mold. In this case, an electrical power of 0.23W was obtained with larger ⊿T above 50K when the external resistance of 10Ω was applied in the circuit. It was clarified that direct contact of thermoelectric brick with the mold and application of the external resistance equal to the internal resistance of thermoelectric modules led to more effective generation of electrical power.
