Abstract
An endless hot rolling material shear-joining method capable of threading hot rolling materials in a finish rolling process without strip breakage by controlling joining conditions for the hot rolling materials in an endless hot rolling process for high carbon steel, and an endless hot rolling plant therefor are disclosed. The shear-joining method for endless hot rolling materials of high carbon steel includes shear-joining high carbon steel metal bars comprising, in terms of weight %, 0.30% to 1.20% C, inevitable impurities, and balance Fe, or comprising 0.15% to 1.5% C containing at least one of Cr, Ni, Mo, V, Ti, W, B, Nb, and Sb, inevitable impurities, and balance Fe, such that a joined surface of the joined metal bars is formed to be inclined in a thickness direction of the metal bars, in a hot rolling plant by a joiner adapted to join the metal bars after overlapping tail part of a leading one of the metal bar and top part of a trailing metal bar.
