Description

Technical Field

[0001] The invention relates to the technical field of silicon carbide product processing, and in particular to a grinding device for rapid processing of silicon carbide products. Background Art

[0002] As a non-oxide ceramic material, silicon carbide has the characteristics of high hardness, high thermal conductivity, good chemical stability, high temperature resistance and wear resistance. Silicon carbide products produced with silicon carbide as the main raw material are widely used in many fields such as industry, electronics, and machinery due to their excellent physical and chemical properties.

[0003] Silicon carbide ceramic burner sleeves are one of the most common silicon carbide products. Silicon carbide ceramic burner sleeves are mainly used in high-temperature combustion devices to improve combustion efficiency, extend service life and improve equipment reliability. Since silicon carbide ceramic burner sleeves are used in high-temperature combustion processes, the smoothness of their inner walls will directly affect the mixing efficiency of fuel and air. Therefore, after the production of silicon carbide ceramic burner sleeves, the inner walls need to be evenly polished. Grinding can eliminate the unevenness and burrs of the inner wall, reduce wear, and extend the service life of the burner sleeve. At the same time, the evenly polished inner wall can better conduct heat and improve heat exchange efficiency.

[0004] Currently, most methods of grinding the burner sleeve are sandpaper, grinding wheels or electric grinders. However, the burner sleeve has an irregular structure, and its inner surface is divided into a small-diameter circular ring section, a large-diameter circular ring section and a conical section that transitions between the two. In this case, the convenience of manual grinding is very low, and for the conical section, in order to ensure the grinding effect, the grinding wheel needs to maintain vertical contact with the conical surface, but it is difficult for a manual handheld grinding device to maintain this working state continuously. As a result, the overall grinding difficulty of the burner sleeve increases, and the overall operation is time-consuming and labor-intensive, which is not conducive to ensuring the processing efficiency of the burner sleeve.
