ABSTRACT:
An apparatus for treating grease-covered rolling mill scale, according to which the rolling mill scale to be treated is weighed, thoroughly mixed with from 10 to 20% by weight of a solvent e.g. a fluorized chlorohydrocarbon, while finely distributing the greases in the thus obtained mixture. The mixture is then added in a continuous manner to a bath containing such solvent, and is distributed therein. The rolling mill scale is then slowly moved out of the solvent containing bath while mixing the rolling mill scale with an oil-free solvent of the above mentioned type passed in counter-current flow to the last mentioned mill scale. The movement of the thus obtained last mentioned mixture is continued while causing the solvent to drip off out of the grease-free rolling mill scale. The rolling mill scale is then heated, and the residual solvent is driven out of the rolling mill scale. Finally, the grease-containing solvent is regenerated by distilling the same, and the oil-free solvent is condensed and fed back to grease-covered rolling mill scale to be degreased.
