FIELD: process engineering.
SUBSTANCE: invention relates to removal oil from oiled iron/steel chips and scale of rolling process slimes. In compliance with proposed process, oiled scale of rolling process slimes, oiled iron/steel chips sized to not over 15 mm and clean process water are mixed at the ratio of 2:1:6. Then, they are processed in reactor with magnetic field of 50 Hz frequency and intensity varying from 200 A/m to 1100 A/m to produce clean scale and chips.
EFFECT: efficient, non-polluting process.
