Description

Technical Field

[0001] This utility model relates to the field of silicon carbide ceramic technology, and more specifically, to a silicon carbide ceramic boat support structure. Background Technology

[0002] Silicon carbide ceramics are engineering ceramic materials with excellent performance. Their main component is silicon carbide, and they exhibit outstanding performance in many high-temperature, high-pressure, and corrosive environments. A boat support structure is required during the processing of silicon carbide ceramics to provide stable support. However, existing boat support structures have a fixed overall length, making adjustment inconvenient. This results in poor support stability for longer silicon carbide ceramic products, and there is a lack of suitable reinforcing support mechanisms. Furthermore, after adjusting the reinforcing support mechanism, there is a lack of a suitable quick-locking mechanism, further compromising stability. Additionally, after the silicon carbide ceramic product is installed on the boat support structure, there is a lack of a suitable top limiting mechanism, which affects safety. Utility Model Content
