PURPOSE:To provide the method for forming a lubricating film which can prevent the seizure arising at the time of hot rolling iron and steel materials. CONSTITUTION:The solid powder of an alkaline metal oxide, etc., is supplied to the surface of a hot working material to cause the reaction of the scale layer formed on the surface of the hot working material and the solid powder and to melt the powder to form a molten film before the execution of hot working. This film is used at the lubricating film. The lubricating film is higher in reactivity as the material and adhesiveness than the conventional lubricants and, therefore, the effect of preventing the seizure is higher than the effect of the conventional lubricants. |
