イト入側における板温度は １００〜９００℃である。Recently, a process has been proposed in which a thin slab is continuously cast, hot rolled, and then warm rolled. FIG. 5 shows a schematic of equipment for carrying out such a process. Molten steel is supplied from a ladle 2 through a tundish 3 to a mold 4 composed of a belt, and is cast into a thin slab. A rough rolling mill 6 is disposed on the exit side of the continuous thin slab casting machine 1, and the thin slab is immediately rolled by the rough rolling mill 6.The rough rolled plate passes through a looper 8 and then is sent to a finishing mill, i.e. It is sent to a warm tandem rolling mill 11. In warm rolling, the plate temperature at the entrance side of the roll bite is 100 to 900°C.

バ−が発生して製品品質が低下する。By the way, in hot rolling, a slight tension is applied to the plate between a looper and a stand or between adjacent stands in order to adjust the plate thickness or prevent the plate from sliding laterally. In addition, the tension of the plates between adjacent stands is adjusted by controlling the roll speed. Generally, the tension of the plate during hot rolling is 1 kgf/mm2 or less.
(For example, "Loopaless rolling technology"Japan's plastic processing ■
(Trends in technological development) Japan Society for Plasticity Processing +986. P.I.
1803-804) [Problems to be Solved by the Invention] In the warm tandem rolling shown in FIG. 5 or the same type of warm rolling as the conventional hot tandem rolling, the tension of the plate is 1 kgf/mm2 as described above. If it is below, the plate tends to slide sideways during rolling, making rolling unstable, and camber occurs, reducing product quality.

延が不安定となって作業能率が低下する。Furthermore, in warm tandem rolling, if the sheet is rolled while applying tension and water lubrication, the rolls will be severely worn. As a result, there is a problem in that not only the quality of the rolled plate (JC1In) deteriorates, but also the rolls have to be changed frequently, resulting in a decrease in work efficiency. Furthermore, when oil lubrication is performed under almost no tension as in hot rolling, the work roll and plate slip, making rolling unstable and reducing work efficiency.
そこで、この発明は、温間圧延を安定して行うことがで
き、さらにはロール摩耗の減少を図ることができる温間
タンデム圧延方法を提供しようとするものである。Therefore, the present invention aims to provide a warm tandem rolling method that can stably perform warm rolling and further reduce roll wear.
［課題を解決するための手段］

板に、ロールハイド入側における板温度の降伏応力の２
７３以下の張力を与えて圧延する。[Means for Solving the Problems] The warm tandem rolling method of the present invention is characterized in that the plate on the entry side of the row of stands, between adjacent stands, and on the exit side of the row of stands is subjected to plate temperature breakdown on the roll hide entry side. stress 2
Rolling is performed by applying a tension of 73 or less.

の横すベリが発生して圧延が不安定となる虞れがある。The reason why the tension applied to the plate was set to 2/3 or less of the yield stress at the temperature of the plate at the entrance side of the stand is that if a tension exceeding this value is applied, there is a risk that the plate will break. Note that it is desirable that the tension applied to the plate be 2 kgf/mm2 or more. If the tension is less than 2 kgf/+m2, there is a risk that horizontal burrs will occur in the plate during rolling, making rolling unstable.

速くして板に張力を午える。In order to apply the required tension to the plate on the entry side of the warm tandem rolling mill, warm tandem rolling mill 1 is used as shown in Figure 1.
The speed of the priddle rolls 2 and 3 arranged on the entrance side of the first stand 12 and the speed of the work roll 15 of the first stand 12 are adjusted. To apply the required tension to the plates between adjacent stands, the speeds of the work rolls 15 of both stands are adjusted. In addition, in order to apply the required tension to the plate located on the exit side of the warm tandem rolling mill 11, as shown in FIG.
and the speed of the work roll 15 of the third stand 14. The priddle roll 25 disposed on the exit side of the warm tandem rolling mill II may be replaced with a take-up reel 21 as shown in FIG. In any of the above cases, tension is applied to the plate by making the circumferential speed of the roll or reel located on the downstream side of the rolling line faster than the circumferential speed of the roll located on the upstream side.

Therefore, the plate does not slide laterally or cause camber during rolling. Furthermore, even with the use of rolling sump oil, there is no slippage of the plate against the work rolls due to the tension acting on the plate.
