The composition of the lubricant used in the present invention is a composition containing paraffinic hydrocarbons and naphthenic hydrocarbons as main components. That is, the ratio of these main components may be, for example, 50:50, 30:70, or vice versa. Also, the average molecular weight is 200~
350, and preferably has an average carbon number (n) in the range of 15 to 25. Although the viscosity varies depending on the usage conditions, the viscosity under normal usage conditions at 40℃ is 5 to 5.
Those in the 10cst range are used. Further, the lubricant may contain 5% or less of a wear-resistant additive, and the water content is preferably kept to 150 ppm or less from the viewpoint of storage stability and corrosion resistance of the treated plate. The reasons for the limitations of the present invention will be described below.

The main components of the lubricant used in the treatment method of the present invention are paraffinic and naphthenic hydrocarbons with an average molecular weight of 200 to 350 and an average carbon number of 15 to 25. This is because when the lubricant is heated, the lubricant flows down, and if the lubricant is heated further than that, it lacks fluidity after heating.

The temperature of hot air heating immediately before press forming is not recommended because if the surface temperature of the aluminum plate is below 50℃, the heating effect will be small, and if it is heated above 200℃, the lubricant will change in quality or the fluidity will become too large. do not have. The optimum range is 50℃ to 200℃ for the surface temperature of the treated plate.
It is.
