摘要

The present invention relates to an oil cleaning system for a heat treated product capable of removing and cleaning contaminants inevitably caused on the surface of a product by oil such as cooling oil, or pollutants in a heat treatment process for a product. The oil cleaning system for a heat treated product comprises: a cleaning tank; a separation tank divided by a barrier wall while being placed beside the cleaning tank; a separation unit arranged in the separation tank; a discharge pipe having one end connected to the separation unit and the other end arranged to supply the oil, and a cleaning solution to a separable discharge tank; the separable discharge tank having an internal space divided by a separation barrier wall; and a hollow tube-shaped circulation pipe connected between the separable discharge tank and the cleaning tank. The separation unit comprises: an inflow pipe part, a floating body capable of floating the inflow pipe part, and a hollow tube-shaped corrugated pipe part extended from the bottom of the inflow pipe part.
