本発明はロール内に冷却媒体を流通させる如く構成した

関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooling device using a copper strip contact cooling roll configured to allow a cooling medium to flow through the roll, and particularly for cooling a copper strip passing through continuous annealing equipment. This relates to a device for
連続焼鈍設備内に中空孔を持つ冷却用ロールを設け、こ
のロール内に冷却媒体を流通して通板する銅帯を冷却す
ることはすでに知られているところである。It is already known that a cooling roll having hollow holes is provided in a continuous annealing facility, and a cooling medium is passed through the roll to cool a copper strip passing through the roll.

界があシ、形状不良全完全に防止することは困難であっ
た。For conventional cooling rolls, following the idea of completely preventing material deterioration when determining the hearth roll diameter,
For example, large-diameter rolls such as 800φ are used, but when a large-diameter roll is used, the adhesion between the copper strip and the cooling roll partially deteriorates, resulting in uneven cooling of the copper strip. This may impair the quality or, in severe cases, cause defects in the shape of the entire area. In order to prevent this shape defect, it is effective to increase the tension, but the temperature of the copper strip is high and the yield point is low, and there is a limit to increasing the tension because it may cause material deterioration. It was difficult to completely prevent burrs and poor shape.
そこで本発明者等が形状不良発生全完全に防止する方法
として考え出１−たものが本発明である。Therefore, the present inventors have devised the present invention as a method for completely preventing the occurrence of shape defects.

状悪化を板厚０．６〜１．６ ｍの銅帯を７００℃から
４００℃に冷却する場合について調査した。In other words, we focused on the fact that when a steel strip is wrapped around a small-diameter roll, the contact condition of the copper strip with the roll is better than when it is wrapped around a large-diameter roll. As a result of repeated research on the method of arranging small diameter rolls in an arrangement that does not give a (Fig. 1), shape deterioration was investigated when copper strips with a plate thickness of 0.6 to 1.6 m were cooled from 700°C to 400°C.
その結果、第２図に示す如く、
