本発明は、難加工材の圧延方法およびその実施に好適な
圧延設備に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for rolling difficult-to-process materials and rolling equipment suitable for carrying out the method.
高Ｓｉ電磁鋼板は、常温での加工性が悪く、冷間圧延し
ようとすると、延性不足により容易に破断してしまう。High-Si electrical steel sheets have poor workability at room temperature, and when cold rolled, they easily break due to lack of ductility.
このため、この種の材料は温間状態（１００℃前後）に
加熱した後、圧延する必要がある。Therefore, this type of material needs to be heated to a warm state (around 100° C.) and then rolled.
鋼板を加熱する方法としては、鋼板をコイル化し、これ
を焼鈍炉に装入して加熱する方法が最も一般的であるが
、この焼鈍方式には次のような難点がある。The most common method for heating a steel plate is to coil the steel plate, charge it into an annealing furnace, and heat it. However, this annealing method has the following drawbacks.
■焼鈍炉と圧延ライン間でコイルを移動させる必要があ
り、コイルのハンドリングに手間がかかる。■It is necessary to move the coil between the annealing furnace and the rolling line, which takes time and effort to handle.
■設備が大掛かりであり、また運転に大きなエネルギー
が必要であり、ランニングコストがかかる。■The equipment is large-scale and requires a large amount of energy to operate, resulting in high running costs.
■コイルの炉に対する出し入れの際のハンドリングが煩
雑である。■Handling the coil when taking it in and out of the furnace is complicated.
■火を使うため、火災等の危険がある。■Since fire is used, there is a risk of fire.
本発明は、このような問題を生じることなく被圧延材を
加熱し、これを温間圧延することができる方法およびそ
の実施に好適な装置を提供しようとするものである。The present invention aims to provide a method for heating and warm rolling a material to be rolled without causing such problems, and an apparatus suitable for carrying out the method.

にしたことをその特徴とする。Therefore, in the method of the present invention, when hot rolling difficult-to-process materials,
The feature is that the material to be rolled is heated by immersing it in heated rolling oil or a solution containing rolling oil, and then warm rolled.
また、このような方法を実施するための本発明の圧延設

けたことをその特徴とする。Further, the rolling equipment of the present invention for carrying out such a method is provided with a heating immersion bath in which the material to be rolled is immersed and heated in rolling oil or a solution containing rolling oil on the entry side of the rolling line. Its characteristic is that
本発明において被圧延材は、圧延油または圧延油を含む
溶液を満たした浸漬槽に浸漬され、加熱される。In the present invention, the material to be rolled is immersed in a dipping tank filled with rolling oil or a solution containing rolling oil, and heated.

延材に錆を生じさせないようにするためと、圧延油以外
の油を使用した場合、これが温間圧延時に使用する圧延
油と混ざり、圧延に不都合を生じることを避けるためで
ある。Rolling oil is used as a heating liquid to prevent rust from forming on the rolled material during heating, and if oil other than rolling oil is used, it may mix with the rolling oil used during warm rolling. This is to avoid any inconvenience during rolling.

ルの場合には、洗浄性よりも潤滑性に優れている牛油脂
系を使用することが好ましい。As the rolling oil, mineral oil-based, beef fat-based, palm oil-based, ester-based, etc. can be used, but if the rolling mill for warm rolling is a mill-clean Mineral oil, which is similar to the rolling oil, is preferable because it has better cleaning properties, and in the case of a mill that performs ECL cleaning, it is recommended to use beef oil, which has better lubricity than cleaning properties. is preferred.
このような圧延油は、そのまま若しくは水等の液体で希
釈して用いられる。Such rolling oil is used as it is or diluted with a liquid such as water.
槽内の液体は１００℃前後の温度ｂこ加熱され、被圧延
材は、例えばストリップコイルの場合、略８〜１２時間

される。The liquid in the tank is heated to a temperature of around 100°C, and the material to be rolled, for example in the case of a strip coil, is heated to a temperature of around 100°C by being immersed in the tank for about 8 to 12 hours.
加熱された被圧延材は浸漬槽から取り出され、直ちに圧
延ラインで圧延される。The heated material to be rolled is taken out from the dipping bath and immediately rolled on a rolling line.

置に対する被圧延材の出し入れも比較的容易である。According to the present invention, the immersion bath serving as the heating device is a smaller-scale facility compared to the annealing furnace, so it can be installed close to the entry side of the rolling line, and therefore the material to be rolled can be placed in the heating device. It can be easily loaded into the rolling line. In addition, the -3 heating device can be operated with less energy and running cost than the annealing furnace method, and it is relatively easy to take the rolled material into and out of the heating device.
