Dry brushing method for cleaning surface of steel belt

The invention discloses a dry brushing method for cleaning the surface of a steel belt, and relates to a device for removing oxide skins of the surface of a plate belt material. The steel belt penetrates space between an upper brush roller and a lower brush roller by the aid of a steel belt surface cleaning dry brushing machine. When a single surface of the steel belt needs to be cleaned, a lifting mechanism is adjusted, so that the lower brush roller and the upper brush roller rise or fall on the whole, and the lower brush roller or the upper brush roller contacts with the single surface of the steel belt and cleans the single surface of the steel belt. When double surface of the steel belt needs to be cleaned, a brush roller moving mechanism is adjusted to drive the upper brush roller and the lower brush roller to synchronously and eccentrically rotate on the whole, the height of the upper brush roller gradually falls, the height of the lower brush roller gradually rises, and the upper brush roller and the
