Steel mill flume water treatment |
摘要 |
The invention comprises a method of preventing deposition of oil on steel mill scale particles comprising adding from about 1 part per million to about 500 parts per million of an amine acrylate/acrylic acid copolymer to mill flume water. Once the copolymer is added, deposition of oil onto scale particles is prevented. The recovered mill scale has less than 2% oil by weight on the scale, making it suitable for recycle to the steelmaking process. Oil and water are subsequently separated with a greater percentage of oil being recovered.
