Abstract：Leveling process is an important way of control plate shaped , it directly determine the quality of the product.After the correction, it could gain good flatness and low residual stress .Backup rollers, as the main force components , its reliability badly affects safety usage of the equipment .Experimental research on the actual and simulated values under backup support roller bearings were compared , to achieve online monitoring the forces of supporting rollers .The study found that the forces of the entire set of supporting rollers rendered high in the middle, while low tendency on both sides .Due to incoming shape and mounting accuracy , there is a load impact and signal unusual phenomenon on few individual support rolls .At present , there are risks of damage and distortion in the backup roll which material selection and layout could be improved .This paper provides a basis for rational use and potential transformation .
