    The invention relates to the production of sheets of aluminum alloy for deep drawing of an alloy, in particular sheets obtained from strips by casting between rolls. The aim of the invention is to improve the quality. The method involves casting an alloy between rolls to obtain a strip, mechanically cleaning the strip with a brush with metal or composite bristles. Then heat treatment is carried out in air. If the strip is rolled up, it is heated for 8 hours to 500-520 ° C. In the case of continuous production, the strip after exiting the casting machine and cleaning is heated to 600-620 ° C for 5 minutes. After heat treatment, rolling to a final thickness of 0.3 m follows, which may be followed by intermediate or final annealing. Then the strip is cut into disks, from which products can be obtained by shtyashovki and subsequent stretching. 3 tab. i W with about O) 4 00 4 sy

    This invention relates to the production of aluminum alloy products suitable for deep drawing, in particular to sheets obtained by casting between rolls.
    The aim of the invention is to improve quality.
    In the process of obtaining products by cold stamping and subsequent drawing from sheets of aluminum alloys, it is often observed that the tool is pinched in the metal, resulting in scratches on the products, which reduce the strength of the products, and in some cases there is a rupture. In addition, defects on the walls of the products may affect the color and gloss of the surface.
    These defects are related to the state of the surface of the workpiece. To prevent these phenomena, the proposed method includes mechanical cleaning of the strip and subsequent thermal treatment in air by heating the strip to 600-620 ° C for 5 minutes or by heating the coiled strip to 520-550 C for 8 hours. Mechanical cleaning of the strip is carried out in continuous mode, and can be carried out using any known device that allows to remove particles from the surface and a thick oxide layer formed during casting. Such cleaning may occur when a strip is passed by means of a rotating brush with metal or composite (for example, nylon with tungsten carbide) bristles. The brushing can be carried out in the direction of passing the strip with the help of a stationary cylindrical brush, whose width is slightly larger than the width of the strip, and the axis is perpendicular to this direction. It is also possible to use a cylindrical Ptlet of small length with an axis parallel to the direction of passing the strip, with transverse translational movement so that it evenly clears the entire width of the strip with some layering at each house moving back and forth.
    The rotational speed of the brushes is adjusted to expose the aluminum surface.
    R
    You can also use a gas jet of pressure from a portable unit to clean the surface.
    The brushing can be carried out directly at the exit of the casting machine, where the temperature does not exceed and the metal to the brush is not
    glued. Cleaning can also be carried out after a single pass of the rollers when the strip reaches a thickness of approximately 2.7 mm.
    Cleaning can be carried out on one or on the other side of the strip, depending on the purpose of the product. In the case of cleaning the cans strip, clean the side that will be the outside of the can.
    After this treatment, by heat treatment in air, a structure is formed on the surface of the IOLOSEA, in which, during the process of stamping products from a strip, there is no jamming of a punch in the metal, gaps and scratches. Heat treatment in air can be carried out after winding the strip into a roll at the exit of the casting machine. In this case, the heating is carried out up to 520–550 s for 4–8 h. Heating to a lower temperature and for a shorter time leads to a deterioration of the anti-creep properties during stretching, and heating to higher
    temperatures - to uneven color and gloss, which leads to the culling of products, in particular cans. Heat treatment of the non-parallel strip can also be carried out. In that
    In this case, the heat treatment is carried out at the exit of the casting mold immediately immediately after cleaning. Under these conditions, the duration of heating is 1–10 min. In the case of furnaces with
    a very long span the temperature is 600-620 ° C. Heat treatment can be carried out in an electric furnace, a fiery furnace or a furnace with a controlled atmosphere can also be used.
    Heat treatment is optimized depending on the type of furnace, its more than 1-shee less humid atmosphere, on the content of manganese and magnesium in the alloy. The higher the magnesium content, the shorter the processing time and the lower the temperature. After heat treatment, the strip is rolled to a thickness
    0.34 mm. Rolling can be followed by intermediate or. final annealing.
