スリンプ疵を綱板３に与える欠点がある。<Problem to be solved by the invention> However, in the device of the above-mentioned Utility Application No. 1-34816,! The magnet roll 15 directly contacts the surface of the steel plate 3 to attract and remove the fine iron powder 16, but it is difficult to match the peripheral speed of the electromagnetic roll 15 and the advancing speed of the steel plate 3.
This has the disadvantage of causing slimp scratches on the rope plate 3.
また、微鉄粉１６は鋼板３と電磁石ロール１５間に圧着
された後で吸着・除去されるので、圧着された時に鋼板
３に凹み疵が生じる欠点がある。Further, since the fine iron powder 16 is adsorbed and removed after being pressed between the steel plate 3 and the electromagnetic roll 15, there is a drawback that dents may occur in the steel plate 3 when the iron powder is pressed.
また、電磁石ロール１５は電動機を必要とし、ライン速
度に追従する制御などが必要となり、設備費用もかさむ
欠点もある。In addition, the electromagnetic roll 15 requires an electric motor, requires control to follow the line speed, and has the disadvantage of increasing equipment costs.
本発明は、これらの欠点を解決した微鉄粉除去装置を提

０に集納される。Inside the electromagnetic roll 8, an electromagnet 12 is installed in a bracket 7) 17, and is supplied with power from the outside via a cable 18. 'The outer cylinder I3 of the W electromagnetic roll is made of non-magnetic material such as stainless steel, so the fine iron powder 16 attached to the outer periphery of the outer cylinder 13 near the electromagnet 12 is transferred to the part of the outer cylinder 13 where the magnetic force is weakened. It is easily removed by the installed wiper 9, and the catch is removed by the tray 1.
It is collected in 0.
