Abstract

According to the present invention, a layer of a thermal-insulation aluminium coating is applied according to a gaseous thermal spraying method onto the surface of a sheet preform, wherein said layer has a thickness of between 0.08 and 0.30 mm with a granularity ratio of up to 5 %. The coating thus obtained is impregnated with a chemical reactant. After the drying step, the preform is ironed according to a reduction ratio of between 2 and 5 %, followed by a sheet-by-sheet hot rolling process. Before finishing the surface of the sheets thus obtained, the method may involve a hydro-abrasive cleaning from the deformed layer.

The thickness of the sheet is 4 mm. Each billet with metal was coated with a protective coating of 0, 20 mm thick by means of electric arc spraying. The resulting treatment was fed with a chemical reagent) and dried on the air for 12 hours. Then the preparations were heated and ironed in the rolls of the country with a degree of 4. The degree of irregularity of application of the coating was no more than 3%. Hot sale of leaves to the final size was mainly due to the fact that they were received from the Chinese population. The process of handling was stable, easy to control, the values of efforts did not exceed the permissible.

To reduce the cost-effectiveness of operations, products for the removal of an inexpensive layer were studied with an alkaline-acid and hydro-active method. The alkaline-acid method does not completely and equally remove the odor. The use of a hydraulic method has made it easier to remove the waste and reduce the quantity of waste by δ - 13.
