Abstract:Roll is an important consumable in iron and steel enterprises. The reduction of roll consumption is also one of the requirements to reduce costs and increase benefits for iron and steel enterprises. Strip broken and adhesion are prone to happen in silicon steel production. It maybe cause backup roll (BUR) to generate surface spalling and crack. Therefore,the wear and tear of rolls increase and the matching between rolls becomes difficult. Reasonable strategy for the matching among various roll diameters can facilitate the roll management and reduce unnecessary grinding quantity and cost. However,backup roll is one of the important components affecting the rolling stability. The effects of the difference between backup roll diameter in work roll driving UCM mill on driving torque in acceleration and deceleration process were analyzed according to dynamics principle. The effects of the flattening rate between backup roll and intermediate roll (IMR) on the strip thickness setting and the controlling precision were analyzed based on the principle of elastic mechanics. The latest application shows that a reasonable strategy for the matching among various roll diameters not only will not affect the manufacturing process,but also is benefit to the roll management and the cost reduction.
