• the material that is the bars, rods or sheets I to be rolled are rubbed over before or during rollms with an oil-like substance mentioned further mow; which has a high boiling point, of at least 200' 0., which leaves during rolling a; resin-like, firmly adherent, plastic and rollable coating, and
• the rolls are preferably coated with the some oiltccizlve loyer; tar fat oils, tar-oils, carbolineum, anthrooene-oil, heavy oils and the constituents thereof of synthetic origin, for example tricresyl phosphate, that; is in general oily substances in liquid, gaseous or vapour form which enable a rollable plastic resin-like layer to be formed on the metal.
• the protective coating which forms this layer during rolling, is one adopted at the same tim to hinder oxidation oi the metal during annealing and to protect the sheets against atmospheric action duringoizorcgew
• the aforementioned resin-like coating combines with and integrates the oxide particles on the surfooe of the magnesium sheet producing u resultant protective layer which is maintained throughout the entire rolling process inasmuch as it is resistant to rolling, bending, etc.
• a process for rolling magnesium and alloys thereof which comprises the step of providing the surface of the material to be rolled with a, resinlilre coating which contains oxide of the said materlol as o component thereof and which forms a. rollable protective layer between roll and mabcriol.
• a process for rolling magnesium and alloys thereof which comprises the steps of providing the surface of the material to be rolled with a. resinlike coating which contains oxide of the said material as a component thereof and which forms a rollable protective layer between roll and material and maintaining such layer during substantially the entire course of rolling.
• a process for rolling magnesium and alloys thereof which comprises the steps of providing the surface of the material to be rolled with a resin-like coating of a. substance which combines,
• a process for rolling magnesium and alloys thereof which comprises. the step of providing the surface of the material to be rolled with an oil-like coating of a substance which forms, in combination with the oxidoskin of the said material, a rollable protective layer between roll and material and also protects the material against oxidationduring annealing and the rolledmaterial against atmospheric action during storage.
• the step which comprises rubbing on 2 the material an oil-like substance which has a boiling point of at least 200 C., which during rolling leaves, in combination with the oxide skin of the said material, a resin-like, firmly adherent and rollable coating and which forms a protective layer between roll and material.
• An article for the production by rolling of sheet material of magnesium or magnesium alloy comprising a billet of. the material and a coating thereon of an oil-like substance which forms, in combination said material, a rollable protective layer between roll and material in the rolling operation.
• An article for the production by rolling of sheet material of magnesium or magnesium alwith the oxide skin of the as iases loy comprising a billet oi the material and. a coating thereon or an oil-like substance which forms, in combination with the oxide skin of the said material, a resin-like firmly adherent and rollable layer between roll and material in the rolling operation.
