The prior art will be explained using FIGS. 1 to 3.
FIG. 1 is a diagram showing the overall layout of a typical Stetzkel mill. The rolling mill 1 shown in the figure includes a pair of upper and lower work rolls 4 equipped with roll bending means, a pair of intermediate rolls 3 that support the work rolls 4 and are movable in the roll axis direction, and a pair of intermediate rolls 3 that support the intermediate rolls 3 and are capable of carrying loads. It is comprised of a pair of reinforcing rolls 2 that transmit the information. Then, in a rough rolling mill (not shown) disposed in front of this rolling mill, the slab is reversibly rolled from about 150 mm to about 17 mm, and then finished rolled in this rolling mill 1. The rolled material 7 that has left the rolling mill 1 is then wound around the heating coiler 6 located in the direction of the exit side of the rolled material.
The rolled material 7 is heated by a heating device such as a burner provided in the , is unwound again, and is rolled in the rolling mill 1 , and then heated by a heating coiler 5 located on the opposite side in the direction of the input side of the rolled material.
After being rolled up and heated at the unwinding mill 1, it is further rolled again at the rolling mill 1. Such a reversible rolling process is repeated until a predetermined finished plate thickness is obtained, and a finished coil is produced by winding with a down coiler (not shown) provided further back in this figure.

いていた。 A diagram showing the end state of winding onto the heating coiler 6 is shown below.
As shown in FIG. 2, in order to unwind the rolled material 7 again, the end 7a of the rolled material 7 must be placed on the pinch roller 9. However, since the pinch roller 9 was provided outside the heating coiler 6,
There was a drawback that the tip 7a of the rolled material was not heated and the temperature decreased during the reversible rolling process. Figure 3 shows the temperature distribution of the rolled material during such a rolling process, where the temperature at the leading and trailing ends decreases by Δt compared to the center of the sheet.
This increases the deformation resistance at the front and rear ends, leading to increases in rolling load and power, variations in plate thickness, and poor shape.

Next, a Steckel mill, which is an embodiment of the present invention, will be explained with reference to FIG. Note that the structure of the rolling mill 1 itself is the same as that shown in FIG. 1, so a description thereof will be omitted. Induction heaters 26 and 27 are provided between the rolling mill 1 and heating coilers 5 and 6, and thermometers 28 and 29 are provided between each induction heater 2.
6 and 27 are installed on the side of the rolling mill 1. Furthermore, an induction heater 20 is provided further behind the rear heating coiler. In the rolling process in this embodiment, the rolled material 7 that has been roughly rolled by the rolling mill 1 or a rough rolling mill (not shown) installed in front of the rolling mill 1 is further subjected to finish rolling in the rolling mill 1. Rolled material 7 has a plate thickness of 8
After rolling to around 1.0 mm, the rolled material 7 is coiled and reheated by heating coilers 5 and 6, unwound, and further rolled by rolling mill 1. In this finish rolling process, at the end of the heating coiler winding, the leading and trailing ends of the rolled material are located at the pinch rolls 8 and 9, and are not heated by the heating coilers 5 and 6, so the leading and trailing ends of the rolled material 7 are placed between the induction heaters 26 and 27. The material is heated to the temperature of the center and then rolled. In addition, the temperature of the rolled material (especially at the leading and trailing ends) is measured using thermometers 28 and 29, and this is input to the control device 30, where the induction heater 2 is controlled based on the measured temperature.
Controls the power of 6,27. In the final bus, the material unwound from the heating coiler 5 is rolled by the rolling mill 1, and sent to a hot run table (not shown) behind the heating coiler 6 without being wound up by the heating coiler 6. In order to perform direct annealing by rapidly cooling the rolled material on this hot run table, it is necessary to maintain the temperature of the finished rolled material at around 1100℃, but if it is lower than this temperature, the induction heater 20 is further used. Heat.
