ス用のループ保熱設備に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loop for a thickness reduction press capable of holding and transporting a thickness slab manufactured from a continuous casting facility and reduced in thickness by a thickness reduction press and carried out during loop forming. Related to heat retention equipment.

板厚スラブとはプレス成形後のスラブをいう。In recent years, there has been proposed and disclosed a method in which the thickness reduction on the upstream side of a slab cast by a continuous casting facility is performed by a thickness reduction press regardless of a group of rough rolling mills (for example, Japanese Unexamined Patent Application Publication No. Sho 61). -235002). In this application,
The thickness slab refers to a slab after press forming.

備コストの低減と圧延ラインの短縮化等ができる。As shown in a schematic view of FIG. 4, this slab forming apparatus 1 comprises a pair of upper and lower slabs 2 produced by a continuous casting apparatus (not shown), each of which is inclined toward a rolling line P and has a parallel portion continuous with the inclined portion. A press 4 holding a mold 3 having a portion for reducing the slab 2 to a predetermined plate thickness under high pressure, and a grooved roll 5 for correcting a shape defect of the slab width end caused by the plate thickness of the press 4. And a horizontal rolling mill 8 having a pair of upper and lower work rolls 7 further downstream thereof. With this configuration, the slab can be pressed at a high pressure, so that a large amount of reduction can be obtained as compared with rolling. Therefore, one press can reduce the number of rough rolling mills by five to six, thereby reducing equipment costs and shortening the rolling line. And so on.

とができないという問題点がある。[0004] However, in the case of FIG. 4, since the forming speed at the time of reducing the thickness of the press 4, the rolling speed at the rolling mill 8, and the conveying speed therebetween are different, the slab 2 being conveyed is stagnated. No device (eg, loop device) for adjusting the respective speeds between them is provided. For this reason, there is a problem that productivity is reduced due to the time required for the adjustment work, and a high-speed rolled material cannot be obtained because the transport speed cannot be increased, thereby lowering the temperature.

We have applied for a rolling line in which a loop device is arranged between the press and the rolling mill.

延材を製造できる。[0006] As shown in FIG. 5, the hot rolling equipment 10 includes a slab 12 cast by a continuous casting machine 11.
Is heated in a slab heating / heating furnace 13 and is subjected to a width reduction press 14.
The width is reduced to a predetermined amount by a thickness reduction press 15 and the thickness is reduced to a predetermined amount by a thickness reduction press 15, and is retained for a required amount by a loop device 16, the width is regulated by a vertical rolling mill 17, and the final rolling is performed by a finishing mill group 18. A rolling line P is configured so that a rolled material 19 having a thickness of a product is roll-formed and wound into a coil shape by a winder 21 via a pinch roll 20. In this way, the loop device 16 is arranged in the rolling line P, and the thickness reduction press 15 on the upstream side is used.
The difference between the thickness forming speed in the above and the rolling forming speed in the downstream finishing mill group 18 and the difference in the conveying speed are further adjusted by the loop device 16 which forms a required amount of loop shape and stays there. Rolled material can be manufactured continuously at high speed by eliminating the speed difference easily.

材が製造できなくなるという問題点がある。However, the loop device shown in FIG. 5 employs a system in which the loop shape is formed by its own weight of the conveyed thick slab, so that a considerably long space is required to form the loop, and, for example, the loop is formed within elastic deformation. In order to form a loop shape of a thick slab, a length of 10 m or more is required, and there is a problem that the rolling line P is extended. What is more problematic is that, in the case of FIG. 5, the sheet thickness slab carried out of the sheet thickness reduction press is not subjected to any heat preservation measures in this looper apparatus, which has a considerably long distance, in a heat-dissipating state. Since the loop is formed and transported by its own weight, the temperature drops considerably and is carried into the finishing mill group. Due to the influence of the temperature drop, the inlet temperature in the finishing mill group required for the rolling forming of the final product thickness can be secured, so that there is a problem that a high quality rolled material cannot be manufactured.

This allows the thickness slab maintained at an appropriate temperature to be carried into the finishing mill group, so that a rolled material of a high-quality final product can be roll-formed.

With this configuration, the fixed-type heat shield cover has a substantially U-shape in which the front and rear surfaces are opened in a direction not to interfere with the width of the sheet thickness slab in the rolling line direction and the lower surface is opened. The heat shield cover is a front and rear surface device of a loop table that performs an operation of starting formation of a loop shape and an operation of returning to a passing plate line X, and is attached to a side surface of a first pinch roll and a second pinch roll described later. Because of this, the heat retaining effect is slightly reduced as compared with the heat retaining cover that can be raised and lowered, and the heat retaining volume is also increased.However, heat dissipation during transport of the sheet slab and formation of the loop shape is reduced.
