[0002] Traditional metal melting furnaces typically use contact temperature measurement methods, such as thermocouples and RTDs. However, contact temperature measurement requires contact with the object being measured in a high-temperature environment, which can easily cause sensor damage and measurement errors. Furthermore, contact temperature measurement can only measure local temperatures and cannot obtain the temperature distribution of the entire melting area. Furthermore, the metal is easily corroded by slag and molten metal during the melting process, resulting in a short sensor life.

[0003] Therefore, a metal melting simulation furnace for spectral temperature measurement modeling is designed to solve the above problems. Utility Model Content
