Optimization of Roll Profile and Roll Consumption in Hot Rolling Narrow Strip Production line
The hot rolling production line of a certain steel plant has limited means of shape control when rolling narrow section strip steel,and the quality of edge and section shapes does not meet the standards when rolling limit specification strips.At the same time,due to the unreasonable design of the original roll shape of the rolling mill,there is a local peak in the pressure between the rolls,which intensifies the wear of the rolling mill and produces abnormal roll wear,and also makes the quality of the product strip steel unstable during the roll changing cycle.Based on the above issues,fully considering the equipment and process characteristics of a certain steel plant's hot rolling and finishing mill,starting from the design curve of the roll shape,the loaded roll shape model,the elastic deformation model of the roll shape,and the plate shape model,the original roll shape optimization design of the work roll and support roll is carried out.At the same time,based on the theory of roll fatigue,Optimization Calculation Software for Roll Profile and Roll Consumption of Hot Rolling Rolls has been developed and applied on site.It can calculate the depth of the roll fatigue layer,guide the grinding amount of rolls,optimize roll wear,and improve the economic benefits of enterprises.
