Home cold roll mill

The cold rolling mill (CRM) operation imparts hardness, thickness reduction, and desired finishing on steel with various sub-processes like pickling, rolling, annealing, and tempering. During the process, a substantial quantity of oily wastewater is released, out of which emulsion wastewater from cold-rolling is the most problematic to tackle.
