一にすることが出来た。2. Description of the Related Art A conventional hot rolling line is, as schematically shown in FIG. 4A, rolled into a sheet bar having a thickness of 3 to 50 mm by a rough rolling mill, and then further rolled by a finish rolling mill. ~ 1
It had been rolled into a 6 mm thick strip. In this case, the speed at the finishing rolling mill group side is limited by mechanical constraints,
As a result, the inlet rolling speed of the finish rolling mill is limited to a further lower speed, which is approximately the outgoing rolling speed x (the outgoing strip thickness ÷ the incoming strip thickness), so the rolling speed requires several minutes and the rough rolling mill outgoing speed. Since the rolling material on the delivery side of the rough rolling mill was waiting in a sheet form, the temperature of the sheet bar was drastically decreased, and the rolling load was increased due to the temperature decrease, especially at the rear end, and there was a quality problem. As a method for solving this, as shown in FIG. 4 (B), a method is disclosed in which a bar after rough rolling is wound into a coil, and finish rolling is performed while rewinding the bar from the rear end of the bar. By this method, cooling of the entire bar is prevented, and finish rolling is performed from the rear end in rough rolling, so that the temperature difference between the front and rear ends of the bar can be made substantially the same.

号） 等が提案されている。However, in the case of FIG. 4B, when the temperature distribution in the width direction of the bar is focused on, the coil end portion is more likely to cool than the center portion of the width, and there is a problem in making the temperature distribution in the width direction uniform. It was Therefore, in order to solve this problem, a method of transferring the coil while keeping it warm with a heat shield panel A method of heating the end surface of the coil (Japanese Patent Laid-Open No. 7-51726)
No.) etc. have been proposed.

However, a method of rewinding and finishing rolling at the final conveyance position has also been proposed.

This mandrel-based transport means has the excellent features that it can transport the coil to the final position while rewinding it, and that it can be transported smoothly even if the coil diameter is different, and that the outer surface of the coil is not scratched. However, if this transport means is applied to the heating means of the heat shield panel, the heat shield panel needs to be largely cut out, the effective area of the heat shield panel is significantly reduced, and a sufficient heat shield (heat shield ) Was not possible.
