Abstract

To produce steel sheet cross sections, particularly those having a small thickness down to a lower limit of about 30 mm and a width of about 500 to 1500 mm, with high surface quality and at a high casting rate (about 10 m/min) at relatively low expense in continuous casting molds equipped with comoving mold walls defining a casting cross section or cavity, a tubular casting nozzle having a mouthpiece whose width at its exit cross section is less than 50% of the width of the casting cavity is utilized, and the space between the sidewalls of the mouthpiece and the adjacent lateral dams or sidewalls of the casting cavity is bridged by means of two symmetrically oriented rotating wheels provided with ceramic rims. The wheels are of a size such that they simultaneously form a seal together with the mouthpiece and the respective, oppositely disposed lateral dams and casting belts defining the casting cavity.
