Abstract: This paper reviews the significant achievements in quality improvement and performance enhancement of domestic carbon sleeves over the ten years since the implementation of the industry standard "Carbon Sleeves for Silicon Steel in Continuous Annealing Furnaces". By establishing scientific and reasonable industry standards, the anti⁃buildups, oxidation resistance, wear resistance, and ammonia corrosion resistance of carbon sleeves have been markedly improved, enabling a complete transition from import dependence to full domestic production. Furthermore, the future development trends of carbon sleeves are discussed.
