RGILLENG: MAGNESMIEE MD MAGNEfiKWM .llnlins Ziibliu, Glcrheg r, moor Sicchborn, wiincrd Nib u Application November l9, llddl,
sen r un'huccz. lln swinerunc November 29, Eddil (Claims. (9311. 80 -60) It. is known that the rolling of bore and pressed rods. of magnesium and magnesium alloys into sheets mush follow o. very different method from clinic used with, for instance, aluminium. In addilion. to more frequent intermediate anncalings and hot; posses, other poinis musibe kept in mind in order to obtain fouli-frce sheets. In the preschi; or the crib it is not possible to roll mogneeiusn slicers using conventional lubricants beavoidance of the detachment of fine metal portlclcs from the rolls and their rolling into the sheets. For these reasons, after rolling the sheets must be brushed and ground to obtain a smooth surface. Cleaning of the rolls and grinding of the sheets involves expendihlre' of considerable time, the expense of the process is increused, and the output of the rolling mill is reduced.
It has now been found that all these disadvanes can be avoided if the surfaces of the moieriol, that is of the bars, rods or sheets to be rolled, are coated with a protective layer which is maintained during the-whole rolling process. I'm protective layer has the great'odvantage that the oxide skin or the metal is not damaged and dos not adhere to the rolls. As nometal periiclcs are rolled into ihc sheet and the surfocothereof remains mirror-smooth, brushing and g of the sheets ar no longer necessary.
The invention will be further explained by ref- .erence to the following example.
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
which forms a protective layer between the roll and thesheet. For further cold or hot passes 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. Adventogeously core is taken that 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.
What I claim is:
l. 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.
2. 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.
3. 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,
with the oxide skin of the said material to form a. rollable protective layer between roll and material, and providing the rolls themselves with a coating of the said substance whereby said layer is renewed during the rolling process.
like substance. which becomes transferred to the sheet, so that during. further procedure involving intermediate annealing, the protective layer is always renewed, The following substances can be used for example for the formation of the pro} 4. 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.
5. In the rolling of magnesium and llloys thereof, 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.
6. 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.
