Abstract

PURPOSE:To secure stable strip passing property over the entire length from the tip part of a hot rolled steel strip to its tail end by passing the hot rolled steel strip after hot rolling through a rolling mill including the tip while first blowing air. CONSTITUTION:At the time of passing the hot rolled steel strip 1 to which hot finish rolling is applied through the mill while cooling the strip from the begining including the tip part on a hot run table 2, air is blown from air nozzles 7 along the advancing direction of the steel strip 1 in a region, where sensors 4 or the like is arranged, near the outlet side of the finishing mill 3. In this way, the steel strip 1 is cooled so as to be held down just near the outlet side of the finishing mill 3 and camber and waving in the tip part are prevented. Further, in the region on the downstream side of the air blowing region, by injecting cooling water with side sprays 5 along the advancing direction of the steel strip 1, the prevention of camber and waving is further effected and also driving force is not hindered.

2. Description of the Related Art Generally, for hot-rolled hot-rolled steel strip having a thickness of 1.8 mm or less, in order not to impair the threadability on a hot run table,
It is usual not to inject water into the tip of the steel strip. The reason is that when cooling water is sprayed from the upper nozzle to the tip of the steel strip to cool it, this acts as a brake, and the cooling water jet from the lower nozzle floats the steel strip. This is because the driving force for transporting the steel strip will be suppressed. As described above, when water is poured into the front end of the hot-rolled steel strip, the strip running speed of the steel strip becomes higher in the middle portion than in the front end, so that a phenomenon called waving occurs. For this reason, conventionally, on the outlet side of the finishing rolling mill of the hot continuous rolling equipment, about 50
As for m, no water was poured through the plate.

Particularly, in an ultrathin hot-rolled steel strip having a thickness of less than 1.4 mm, even if no water is poured, waving is generated due to the action of air resistance and the like, so that the stripping speed is limited. It was

On the other hand, recently, a means has been adopted in which water is poured from the front of the upper vernier bank in an amount such that the waving does not increase for each plate thickness, and the hot-rolled steel strip is thrust therein. . According to this method, the coiling temperature at the tip of the hot-rolled steel strip is, for example, about 25 mm with a plate thickness of 1.4 mm.
Although a slight cooling effect was obtained in terms of being able to lower the temperature by ℃,
It was still insufficient in terms of suppressing waving.

SUMMARY OF THE INVENTION However, a. The technique disclosed in Japanese Laid-Open Patent Publication No. 56-33119 has a problem in that the yield is reduced because a step of removing the front end of the steel strip is required in the subsequent step. b. Further, in the technique disclosed in Japanese Patent Laid-Open No. 61-102305, it is technically difficult to guide a steel strip being rolled at a high speed, and the mechanism becomes complicated. There was a problem that it could cause a rush depending on the condition. c. Further, the technique disclosed in the above-mentioned Japanese Patent Laid-Open No. 4-84617 has various problems due to the fact that a water injection facility cannot be provided in the immediate vicinity of the rolling mill outlet side. That is, 5 on the exit side of the finish rolling mill
In general, material quality (thickness, width,
Data measurement sensors for guaranteeing (crown, shape, etc.) are installed. Therefore, the cooling nozzle must be installed on the downstream side so as not to cause these measurement failures. Because many of these sensors use optical type, ultrasonic wave, laser, etc.,
This is because the water on the strip or the evaporated water is likely to be affected, resulting in measurement failure. As a result, the following problems have occurred with respect to the sheet passing property. Warp of the hot rolled steel strip tip often occurs in the measuring equipment installation area immediately near the exit side of the rolling mill. If the amount of warp at that time is large, as shown in the schematic diagram of FIG. There was a problem that the water injection by the side spray performed on the downstream side was rather resistance and caused an increase in the warp of the steel strip. Also, as shown in the schematic view of FIG. 4, when there is continuous waving in the middle part of the hot-rolled steel strip in the strip,
When water is injected into this part by side spray, an action of collecting these continuous wavings from the rear by the force of the spray occurs, and as a result, a large waving is obtained. Eventually, the whole body collapsed and overlapped, and if it entered the pinch roll in front of the winder as it was, that part would be folded into a defective part.
