The presence of carbon black precipitation and carbon accumulation in the furnace body promotes electrode deterioration, leading to reduced probe lifespan. During the initial pre-soaking of a new furnace, the atmosphere carbon potential is usually set very high, which can result in carbon accumulation. Therefore, it is principle to not insert an oxygen probe during the pre-soaking phase. Instead, the probe should be inserted only after the furnace has burned charcoal or been maintained with a carrier gas for a period. The overall production process must be set up reasonably to prevent carbon black precipitation and carbon accumulation. Carbon accumulation inside the oxygen probe's protective tube can cause probe damage.
