Abstract

PURPOSE:To manufacture the metallic bar, etc., with smooth surface, high dimensional accuracy and excellent luster at good workability, by cooling the roll surface using the cooling liquid prepared by adding the high boiling point lubricating oil to the low boiling point solvent, on the run-out side of the skin-pass mill. CONSTITUTION:On the run-out side of the skin-pass mill 1, the jacket 7 is installed so as to slidably contact with the surface of the rolls 2, 2', and to be sealed with the sealing gasket 8, etc. In this jacket 7, the cooling liquid, being prepared by adding the 1-20vol% lubricating oil (the spindle oil, for example) of the 120 deg.C or higher boiling point to the solvent (freon-11, for example) of the boiling point 20-80 deg.C, is recycled, etc. Hereby, the rolls 2, 2' are directly cooled and additionally cooled by the vaporization heat of the solvent included in the cooling liquid. Besides, because the thin film of the lubricating oil is formed on the surface of the rolls 2, 2', the friction factor between the rolls 2, 2' and the rolled material 5, etc., is almost constantly maintained.
