つた。 Conventionally, when immersion hardening a steel strip in the continuous annealing furnace, the cooling roll is spaced apart to prevent the steel strip from coming into contact with the cooling roll, but since the cooling roll is located behind the steel strip, However, the steel strip is cooled by radiation, and as a result, the temperature of the steel strip before immersion quenching has to be raised more than necessary, and the operation has to be carried out to compensate for the cooling in the cooling roll section.

室を提供しようとするものである。 The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional method, and it is possible to prevent the temperature of the steel strip from decreasing due to the cooling roll by placing a heat insulating member between the steel strip and the cooling roll during immersion quenching. It is intended to provide a roll cooling chamber.
つぎに、本考案を一実施例である図面にしたが
つて説明する。 Next, the present invention will be explained with reference to the drawings which are one embodiment.

ロール対６が、図においては、二対、パスライン
に沿つて配置してある。 In the figure, T indicates a continuous annealing furnace, and the drawing shows a gas jet cooling chamber 1, a roll cooling chamber 2, a water quenching tank 3, a drainage tank 4, and an overaging chamber 5. In the roll cooling chamber 2, there is a cooling roll pair 6 consisting of a pair of cooling rolls 6a and 6b that rotate at a predetermined angle around the pass line while maintaining a predetermined interval. It is arranged along.
前記冷却ロール対６は、鋼帯Ｓを水焼入れする

ル６ａ，６ｂと接触させるものである。 When the steel strip S is water-quenched, the cooling roll pair 6 is horizontal and the cooling rolls 6a and 6b are spaced apart from each other, as shown in FIG. I'm trying not to come into contact with it.
In addition, when the steel strip S is roll cooled, the water quenching tank 3
The quenching liquid is discharged into the drainage tank 4, and the cooling roll pair 6 is rotated so as to be parallel to the pass line as shown in the second diagram, and the steel strip S is brought into contact with the cooling rolls 6a and 6b. It is something that makes you
なお、前記冷却ロール６ａ，６ｂの操作は、必
ずしも前述のように、冷却ロール対を回転させて
行なう必要はなく、従来のように、各冷却ロール
を移動させて行なつてもよい。 The operation of the cooling rolls 6a and 6b does not necessarily have to be performed by rotating the pair of cooling rolls as described above, but may be performed by moving each cooling roll as in the conventional manner.
前記のように、鋼帯Ｓを水焼入れする場合に
は、冷却ロール６ａ，６ｂは鋼帯Ｓと接触してい
ないが、鋼帯Ｓの背後に位置しているため、どう
しても、鋼帯Ｓは冷却ロール６ａ，６ｂにより冷
却されるのである。 As mentioned above, when water quenching the steel strip S, the cooling rolls 6a and 6b are not in contact with the steel strip S, but are located behind the steel strip S, so the steel strip S is inevitably It is cooled by cooling rolls 6a and 6b.

エイトである。 Therefore, in the present invention, during immersion quenching,
A heat insulating member 7 is placed in the roll cooling chamber 2, sandwiching the pass line of the steel strip S. That is,
The heat insulating member 7 is attached to the chain 8 in a flexible manner.
It consists of a structure in which a heat insulating material 9 is attached, which sandwiches the pass line and also serves as a cooling roll 6 during water quenching.
The inner positions of a and 6b are arranged so that they can be raised and lowered by a drive roll 10. Note that 11 is a counterweight.

に取付ければよいものである。 Therefore, during roll cooling, the heat insulating member 7 (insulating material 9) is raised as shown on the left side of the figure, and during water quenching, the heat insulating material 9 is lowered as shown on the right side of the figure. That is, the heat insulating material 9 is interposed between the steel strip S and the cooling rolls 6a, 6b to prevent the temperature of the steel strip S from decreasing due to the water cooling rolls 6a, 6b. Note that the heat insulating member 7 is
The heat insulating member 7 may be constructed of a plate-like member, and in this case, the heat insulating member 7 does not necessarily have to be installed in the roll cooling chamber 2 so that it can move forward and backward. be.

By intervening,
With a simple configuration, the temperature of the steel strip can be prevented from decreasing due to the cooling roll, and the steel strip can be immersed and hardened in a good manner.
