PURPOSE:To remarkably improve connecting efficiency, by constituting a traveling connector with the preceding traveling connector and the succeeding traveling connector. CONSTITUTION:In a roughing mill 1, the tail end part of the preceding material 5 to be rolled moves in the inside of the preceding traveling connector A started previously, and when the end part arrives at the clamping position, a lower clamp supporting plate 20 is raised to raise the upper surfaces of projections 19 and 19' used for clamping to the upper side above a pass line by driving cylinders 22 and 22' used for driving a clamp. On the other hand, the heading end part of the succeeding material 5' to be rolled is cut by a crop shear 8 to enter the succeeding traveling connector B, and begins to move in rapid acceleration. And the upper surface of projections 19 and 19' used for clamping are raised to the upper side above the pass line to make both materials 5 and 5' abut onto each other by driving the cylinders 22 and 22' used for driving the clamp. In said state, both materials 5 and 5' are bitten by a group of finish mills 2 by applying an electric current on the upper and lower supporting plates 16 and 20, respectively. |
