Steel Mill Maintains Efficient Coil Cooling System with Lakos Separators |
 |
Immersing their hot coils in large tanks reduced the cooling process time for the Sidmar Steel Mill in Belgium from 6 hours to 30 minutes. To prevent an otherwise costly problem of mill scale build-up in their system's heat exchanger, Sidmar chose, instead, the continuous filtration performance scales (created when the coils are dipped into the cooling tanks) were allowed to build-up in the tanks, frequent and costly system shutdowns for cleaning and excessive labor costs would have minimized the system's efficiency and effectiveness.
The overall system, which is computer-controlled, calls for the water in the cooling tanks to be displaced by cool water from their heat exchanger and transferred to a sump after it has reached a specified temperature (see diagram). Individual pumps then freed the water through the Lakos Separators at a combined rate of 8,800 U.S. gpm (2,000 cu. m/hr) and directly to the heat exchanger. Accumulated solids are purged automatically from the Lakos Separators at regular intervals, thereby requiring no routine maintenance whatsoever.
