Abstract: The furnace bottom roller is a key core component in the continuous annealing furnace for silicon steel, and its performance directly affects the stable operation of the production line, the surface quality and yield of silicon steel products. This article mainly compares and analyzes the material characteristics, application performance, advantages and disadvantages of mainstream furnace bottom rollers such as heat-resistant alloy rollers, quartz ceramic rollers, and silicon carbide combined with silicon nitride ceramic rollers. The results indicate that the combination of silicon carbide and silicon nitride ceramic material for furnace bottom rollers has significant advantages in high temperature stability, anti nodule properties, and surface quality maintenance. Based on this, the application of gradient functional materials, roller structure optimization, surface functional coatings, and intelligent and state monitoring are important development directions for the furnace bottom rollers of high-grade silicon steel continuous annealing furnaces in the future.
