1. form the shaggy method of crocodile skin in the continuous casting of a light casting band that is controlled at ordinary carbon steel, may further comprise the steps:

  • Laterally a pair of counter-rotational casting roller of assembling to form clamping-extruding region between the circumferential casting surface of described roller, becomes metal tape by the castable appearance of this clamping-extruding region;

    The casting surface of described casting roller is formed with projection;

    The weight content that forms carbon is lower than the molten metal casting pond of 0.065% carbon steel, and this casting pool is bearing on the casting surface of described casting roller, is positioned at described clamping-extruding region top;

    At the perimeter mounted rotary brush, make it at described casting surface to contact with casting surface of each casting roller with before motlten metal in the described casting pool contacts;

    By in the foundry work process, controlling the energy that described rotary brush applies, clean the casting surface of described casting roller to realize desirable clean-up performance, exposing the most of projections on the casting surface, and make to form between the motlten metal of described casting surface and described casting pool and infiltrate contact;

    Utilize the clean-up performance of described hope as reference, the energy that control is applied at the casting surface of described casting roller by described rotary brush, exposing most of projections of the casting surface of casting roller, and between the motlten metal of described casting surface and described casting pool, form to infiltrate and contact;

    WithCounter-rotate described casting roller so that each the casting roller casting surface move towards described clamping-extruding region, to produce the foundry goods band downwards from clamping-extruding region.
