Description

Technical Field

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

[0002] Silicon carbide, also known as silicon carbide stone, is the most widely used and economical non-oxide high-tech refractory raw material among contemporary C, N, B and other materials. It can also be called corundum or refractory sand. Currently, silicon carbide produced in China's industry is divided into two types: black silicon carbide and green silicon carbide, both of which are hexagonal crystals.

[0003] Sealing rings are one of the main applications of silicon carbide materials. Some existing silicon carbide sealing rings have high hardness and good wear resistance, but lack elasticity and have mediocre sealing performance. In addition, silicon carbide sealing rings are ceramic materials, which are relatively brittle. When the rotation speed is high, silicon carbide sealing rings are prone to breakage due to contact with the medium or foreign objects. Therefore, we propose a silicon carbide support ring structure.
