Abstract

PURPOSE:To effectively press to eliminate cracks, etc., internally included in the edges of the cast slab obtained from the continuous casting, by carrying out the specified high rate edging pass for this slab. CONSTITUTION:The vertical roll type edger rolls 4a provided with upper and lower flanges are used in the high rate edging pass for the cast slab 2 obtained from the continuous casting; these edger rolls 4a perform the high rate edger pass at >=50mm./ one pass, until the total amount of the hot edging becomes >=300mm.. If necessary, after carrying out the hot edging passes by the edger rolls 4a, the material is subjected to the horizontal rolling pass by the horizontal rolls 4b for eliminating the dog bone generated by the rolls 4a.
