<p>PURPOSE:To obtain a titled installation, capable of accurately detecting the front-end position of a rolling stock for the purpose of reducing the variation of sheet width, by setting the 2nd hot-piece detection means on the position the same as that of the 1st hot-piece detection means in the plate width direction of a rolling stock. CONSTITUTION:The rotating angle of roll, from the time the front end of a rolling stock 01 is detected by the 2nd hot-piece detection means 21, after the stock 01 passes through the horizontal mill 7 of a final rolling stand 6, till the time the front end is detected by the 1st hot-piece detection means 11a, is detected by a roll rotating-angle detection means i.e. a pulse generator 9. The distance between the front end of stock 1 and the mill 7 is obtained by integrating said detected values, to control the plate width of stock 1 based on the distance value. Further, both of the 2nd and 1st hot-piece detectors 22, 11 can be provided to the outlet side of the horizontal mill 2 of a rolling stand 1 arranged adjacently to said stand 6 on its upstream side, and further hot-piece detectors 11, 11a, 21, 22 can be respectively provided to respective outlet sides of both stands 1, 6.</p> |
