LAKOS Separators Promote Multiple Savings for Steel Mill

Faced with excessive costs to repair and rehabilitate their strainer-type filtration system, California Steel (originally Kaiser Steel) in Fontana, chose instead to protect the roll steel processing system at their hot strip mill with a manifold of three LAKOS Separators. Removing slag, grit, scale and other solids from the closed circuit supply of water from their own utility’s cooling towers, the LAKOS Separators effectively prevent excessive wear to a system of five high-pressure pumps and have more than tripled the life of their more than 1,000 spray nozzles used to cool rolls and form steel. Additionally, clogged spray headers, once a problem which required weekly flushing, monthly change-out and still occasionally resulted in costly unscheduled shutdowns (up to $1,600/minute) have been completely eliminated.

 

“The end result,” says Mr. Ernie Tudor, Division Lubricating Engineer, Rolling Mill Maintenance at California Steel, “is dramatically increased productivity and noticeably improved quality in our rolled steel.” Tudor, who chose not to repair their old automatically backflushed strainers and initiated the investigation for a suitable alternative, claims the LAKOS Separators are much more effective and reliable than their previous system, offering increased performance and better separation efficiency without the burden or costs of previous routine maintenance.

 

Installed on the full-stream flow from California Steel’s cooling towers to the hot strip mill, the LAKOS Separators: (1) discharge directly to a series of low pressure cooling nozzles and (2) feed a system of as many as five high-pressure pumps which likewise feed high pressure cooling nozzles. The improved nozzle life and reduced incidence of plugging helps eliminate uneven spray pattern and promotes better roll cooling and forming.
