Resumo

THIS ARTICLE DESCRIBES THE ROLL RECLAIMING BY WELDING AND REUSE OF THE VERTICAL EDGER ROLLS IN A HOT STRIP MILL AND THE ADVANTAGES AND ECONOMIC RESULTS. THE ROLL SURFACING MATERIALS SHOULD BE REASONABLY SELECTED AND THE SURFACING REPAIR PLAN FORMULATED BASED ON THE ROLLING OPERATION CONDITIONS TO MAXIMIZE THE ROUGHNESS OF THE SURFACING REPAIR. THE SURFACE QUALITY OF THE ROUGHING VERTICAL ROLLS DURING ROLLING IS CONTINUOUSLY IMPROVED AND THE EDGE QUALITY OF THE STRIP IS IMPROVED, AND THE CONSUMPTION OF THE ROLLS IS REDUCED.
