Method for removing oil from mill scale and recovering
Iron oxide scale is continually formed on the surface of the hot steel. This scale is repeatedly stripped away by the stresses of rolling. The scale falls, together with the emulsified oil, into collection pits beneath the rolling mill, whence the oil emulsion is recycled via sumps and filters. The scale accumulates and is periodically removed.Industrial Pumping Solutions for Steel & Metal Refining,Pitbull Industrial Pumps offers high-quality pumping solutions for metal and steel refining.

After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
