Abstract: A method for improving the structure of brushes in cleaning section of silicon steel annealing line was revealed in this paper. To configure the length of brush roller bristle area by gradient, and single-point control brush roller ascending and descending movement, the cleaning problem of steel strip rolling oil was effectively solved, which significantly improved the cleaning quality of sheet surface, reduced the defects of the final products, and meanwhile reduced the cost of production.

Key words: silicon steel, cleaning, brush roller, annealing line
