Abstract: Treatment process limiting the overoxidation of the sides of a coiled, hot-rolled sheet strip delivered from a strip mill, characterized in that a vitrifiable powder is sprayed onto the lateral portions of the coil, called edges, fusing at the time of its contact with the steel coil delivered from hot-rolling, the sheet strip undergoing cooling at a temperature below the coiling temperature, the cooling of the strip ensuring the solidification of an impervious enamel on the surface of the coil edges and air-tightness of the space contained between the turns of the coil.

Abstract: The present invention relates to a process for treating the surface of a metal part to prepare it for drawing and to protect it temporarily against corrosion, comprising applying an aqueous treatment composition to the surface of said part and drying the aqueous composition so applied, characterized in that the aqueous composition is first obtained by mixing:an aqueous solution comprising at least one alcohol or fatty acid polyethoxylate; andan oil-in-water emulsion comprising at least 3% to 13% by volume of an oil phase comprising at least 75% to 90% by volume of at least one mineral oil and 5% to 10% by volume of at least one surfactant.The invention also relates to the metal parts so obtained.

Abstract: A process for the purpose of preparing the sheet for deep-drawing and/or protecting it against corrosion, wherein an aqueous solution of polyethoxylates of one or more lanolin derivatives is applied to the said surface, the said surface is dried to obtain a deposit in dry state, then at least one operation of oiling is performed on the deposit in dry state.This process makes it possible in particular to simplify the operations of deep-drawing: even after prolonged storage, it is not necessary to re-oil the treated sheet just before deep-drawing.
