| description | PURPOSE:To make the concentration of ferrous impurities in rolling oil controllable and provide stainless steel products with good gloss by immersing a magnet saparator to which a magnet having specified magnetic flux density is attached in rolling oil in a rolling oil tank for a prescribed time to remove the ferrous impurities as low as a specified concentration or less. CONSTITUTION:The lower part of a chain conveyer 3 to which magnet plates 2 with 2000 gauss or more magnetic flux density are attached is immersed in an oil in a rolling oil tank 1 and the chain conveyer 3 is moved in direction shown as the arrow (a) or (b). While passing the liquid surface, the chain conveyer 3 rotates at 30-90 deg. tilting angle against the liquid surface. A plurality of the magnet plates 2 are immersed in the rolling oil for a prescribed time and while moving in the oil, the plates 2 absorb the ferrous impurities, squeeze the effective rolling oil including the ferrous impurities and separate the ferrous impurities based on the magnetic force function, and thus decrease the ferrous impurities concentration to 2000ppm or less in the rolling oil. Then, the absorbed ferrous impurities are scratched and recovered in a scum tank 7 through a scum guide 6. |
