AI Technical Summary

Technical Problem

In existing technologies, during the vapor deposition process of carbon-carbon composite materials, the integral ceramic insulation component is prone to short circuits, the gap insulation has large heat loss and maintenance requires dismantling the furnace, resulting in low equipment reliability and efficiency.

Method used

The system employs an online maintainable gap-type ceramic ball insulation structure. Through the combined design of inner and outer ceramic rings and ceramic balls, reliable insulation performance is ensured. The insulation performance is restored by the point contact accumulation and online agitation of the ceramic balls, avoiding the formation of conductive paths due to carbon deposition.

Benefits of technology

It achieves reliable insulation performance, low heat loss, and online insulation performance recovery, thereby improving equipment utilization and maintenance efficiency, reducing energy consumption, and extending equipment life.
