Abstract

An endless hot rolling method capable of preventing a plate from breaking by assuring a connection strength and reducing a load on rolling rolls so as to prevent a damage to a retainer and the rolling rolls in an endless rolling, comprising the step of standardizing the thickness of all sheet bars in a set to the thickness of a thinnest sheet bar of all sheet bars with the specified thicknesses in a connected set when a finish rolling is continuously performed by connecting the sheet bars before a finish rolling to eliminate a step at a sheet bar connected portion.
