  • Improvement of Seam-defects on Strip Edge of Stainless Steel

    On the hot strip rolling of stainless steel grades, the side seam-defects tend to grow at the slab corner because of the temperature fall. Thus the new technique reducing the width of the side seam-defect by forming the slab edge into concave shape with the sizing press before rolling and preventing the sidthspread on rolling were investigated.
