What are the risks of carbon deposition in mesh belt furnace?

Carbon deposition in mesh belt furnace damages oxygen probe and metal parts in the furnace. According to relevant data, the oxygen probe can not accurately measure the carbon potential in the furnace, which affects the quality of heat treatment, accelerates carbon deposition and damages the oxygen probe and metal parts in the furnace. There is too much carbon deposit, and the carbon black covers the outer wall of the radiation tube, so the heat cannot be dissipated, which leads to the damage of the protection tube and the heating element.
