〈産業上の利用分野〉
本発明は、鋼板の表面に付着した微鉄粉を除去する装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an apparatus for removing fine iron powder adhering to the surface of a steel plate.
〈従来の技術〉
冷間圧延等の鋼板を処理するラインでは、鋼板の表面に
微鉄粉が多く付着している。例えば冷間圧延機により鋼
板が処理されると、ロールの摩耗粉が主に微鉄粉となり
鋼板の表面に付着する。<Prior Art> In lines that process steel plates, such as cold rolling, a large amount of fine iron powder adheres to the surface of the steel plates. For example, when a steel plate is processed by a cold rolling mill, wear powder from the rolls mainly becomes fine iron powder and adheres to the surface of the steel plate.
微鉄粉は製品プレス時に凹み班の品質欠陥となるので、
これらを除去しなければならない。Fine iron powder causes quality defects in the form of dents during product pressing, so
These must be removed.

である。<Means for Solving the Problems> The present invention is characterized in that the running direction of the heald is perpendicular to the advancing direction of the steel plate being conveyed, and the heald surface is close to the plate surface and runs endlessly. , and has a non-magnetic endless heald extending to a point outside the width of the steel plate, and a permanent magnet or electromagnet disposed close to the steel plate surface inside the endless heald, The attached fine iron powder is attracted to the endless heald by the magnetic force of the permanent magnet or electromagnet, and is allowed to fall from the endless belt at a point outside the width of the steel plate where the magnetic force of the permanent magnet or electromagnet does not work. Alternatively, it is an apparatus for removing fine iron powder from the surface of a steel plate, which is characterized by suction using a suction means.

きる。Effect> In the present invention, since the magnet is provided through the endless belt at a position close to the surface of the steel plate, fine iron powder on the surface of the steel plate is easily attracted to the endless heald. In addition, since the endless belt rotates in a direction perpendicular to the direction of movement of the steel plate, fine iron powder can be easily removed from the system from areas where the magnetic force is removed (locations outside the width of the steel plate). I can do it.

すれば、より確実に除去できる。Since the device of the present invention removes fine iron powder without contacting the steel plate, it does not cause quality defects such as scratches. Further, since the fine iron powder is not directly attracted to the magnet, the adsorbed iron powder can be easily removed. Note that it can be removed more reliably by suctioning with a vacuum cleaner or the like.

Significant savings compared to processing equipment.
また、エンドレスベルト及びマグネットの幅は広く取る
必要はないので、取（１スペースが狭く、任意の場所に
設置可能である。In addition, since the endless belt and the magnet do not need to be wide, each space is narrow and they can be installed at any location.
