れている。<Prior art> Rolling rolls such as the work rolls of rolling mills are heated by processing heat generated during rolling of the metal strip, which causes a rise in temperature, which adversely affects the roll crown and deteriorates the rolled shape of the metal strip. For example, during cold rolling of steel strip, if the roll cooling liquid is still attached to the steel strip and the steel strip is wound into a coil, the winding may become misaligned during winding. To prevent rust, a sealing device is provided to seal the roll coolant from falling onto the steel strip.

FIG. 3 is a graph showing the relationship between the gap h between the tip of the sealing material 5 and the outer peripheral surface of the work roll 2, the circumferential speed V of the work roll 20, and the distribution of the flow speed V of the roll cooling liquid.

冷却液の流速Ｖの方向が下方の部分が存在する。Figure 3 (a) shows the flow rate of the roll cooling liquid when the work roll 20 circumferential speed V is equal to or higher than the lowest work roll circumferential speed Vo that does not cause a seal failure determined by the gap and the roll coolant seal is good. An example of a distribution is shown. In this case, the direction of the flow velocity V of the roll cooling liquid is upward over the entire area. FIG. 3(b) shows that the circumferential speed V of the work roll 2 is the threshold 4fiV.
An example of the flow velocity distribution of the roll cooling liquid when the sealing of the roll cooling liquid becomes defective is shown below. In this case, there is a portion where the direction of the flow velocity V of the roll cooling liquid is downward.
また、本発明者らは、ワークロール２の周速Ｖとシール
不良とならない間隙りとの間には、第４図の関係がある
ことを見出した。Further, the present inventors have found that there is a relationship shown in FIG. 4 between the circumferential speed V of the work roll 2 and the gap that does not cause sealing failure.
従って、シール材５の先端と圧延ロール２の外周面との
距離を第３図の斜線で示す範囲内に収めれば、非接触で
冷却液をシールすることができる。Therefore, if the distance between the tip of the sealing material 5 and the outer circumferential surface of the rolling roll 2 is within the range shown by diagonal lines in FIG. 3, the cooling liquid can be sealed without contact.
これによって、シール材５と圧延ロール２の外周面の間
