Steel Mills: Removing Oil from Scale Pits

Oil Skimmers, Inc. has provided oil removal solutions to many steel mill companies to date. One customer, a steel mini-mill, had employed a vac truck service to periodically vacuum waste oil out of its scale pit. But vacuuming takes a lot of water along with the oil, and occasional visits didn't provide a solution to a continuous problem.Mill Scale Sump Solution for a Steel Mill Hevvy Pumps,A steel producing partner of ours in the northeast U.S. was having major operational problems in their mill scale pits because the pumps that they had installed were nothing more than glorified water pumps pretending to be slurry pumps. Because they didn’t have the right pumps installed, every two hours they were having to hoist these glorified water pumps out of the mill scale that wasMill scale Wikipedia,May 06, 2009· Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.

Descale Pump Energy Savings TMEIC

High pressure water jets are used to remove scale from the steel bars before they enter the rolling mill. The descaler pump runs at constant speed, and the high pressure water is bypassed to the water pit when no bar is present. Running the pump at constant speed wastes energy and water, and heavyIndustry: Steel,From scale pits to cooling water and wastewater treatment areas or final discharge ponds, there are various points where oil is bound to meet and mix with water throughout the steel production process. Successfully removing and recovering oil from these various applications delivers significant benefits to those in the steel industry, including:A steel mill's scale solution reduces water treatment,In steel production, hot milling and casting uses water at rates of between 100m3/h and 10000m3h depending on the scale of the operation. As steel leaves the casting operations, cooling and cutting with water produces mill scale (iron oxides). Mill scale particles range from a few microns up to the size of a fist. They are heavy and abrasive.
