In the art 6 of rolling thin wide strips of steel in a i-high fig g figfig zg gg gig g ggzg the mill, it is of extreme importance that a satisfactory medium be employed. Per cent According to the prior art, numerous media Palm 9 15 have been employed, including mixtures of water 10 Water and oils of various types. While some of these Lactic acld media serve quite well as coolants, they tend In practice, the solution or liquid mixture is toward breaking down during the rolling operasprayed through nozzles against the surface of tion because of the high heat encountered and the working rolls and on the surface of the strip thus have little or no lubricating value. being rolled, pressure being applied by any suit- So far as I am aware, all prior art mixtures ablemeans.
