BORIDE ZIRCONIUM TIPS FOR IMMERSION THERMOCOUPLES

Abstract

ZrB2 protective tips for immersion thermocouples were evaluated with respect to thermal stability, pitting, and service life. In a Martin furnace, tips are pitted by basic slags and disintegrate within 30-40 min. When immersed in molten steel for 40-45 min, the outer diameter of the tips does not s rink. Thermal stabili y tests showed that tips could be immersed in an open-hearth bath for as many as 20 times without decrepetations or surface changes.AD- * *(!(N6 ++Evaluation of zirconium boride tips for immersion thermocouples.
