Special multi-point thermocouple for blast furnace hearth erosion monitoring system

The dedicated thermocouple for blast furnace hearth erosion detection system is mainly embedded in the bottom probe of the blast furnace. By detecting the temperature of each temperature point, it can provide three-dimensional feedback on the temperature of the furnace bottom. This thermocouple is centrally led out, has good airtightness, has fewer on-site openings, avoids areas such as tapping holes, has a long service life, and is easy to maintain.
