摘要:
H-shaped steel products having substantially a constant web height are efficiently manufactured from workpieces after breakdown rolling by using a particular universal rolling mill comprising a pair of width variable horizontal rolls and a pair of vertical rolls in rough universal rolling and/or finish universal rolling stages without arrangement of rolls in the same size series having different flange thicknesses.
