    The invention relates to ferrous metallurgy, specifically to the continuous casting of steel tapes. The goal is to reduce the wear of the mold and improve the quality of cast tapes. The mold for continuous casting of steel strip with cooled wide and narrow side walls is expanded upwards in the area of wide side walls to form a funnel-shaped zone for the injection pipe, and has parallel end sections to the side. To reduce the strain in the shell of the preform, as well as to improve the distribution of the melt, the mold has rectangular transition surfaces that transform along the horizontal line to the format-defining lower portions of the wide side walls. 1 hp f-ly, 6 ill.

    The invention relates to ferrous metallurgy, specifically to the continuous casting of steel tapes.
    The purpose of the invention is to reduce the wear of the mold and improve the quality of cast tapes.
    FIG. 1 shows a mold, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - mold, top view version; in fig. 4 - section bb in fig.Z; in fig. 5 is the same; in fig. 6 is a sectional view BB in FIG. 4 and 5.
    The mold for continuous pouring contains two opposite wide side walls 1 and 2 and two
    narrow side walls 3 and 4, located between the parallel side zones of the wide side walls with the formation of the working cavity. To cool the wide side walls 1 and 2, cavities 5 are made in them, to which highways are connected for supplying 6 and discharging 7 coolant. The narrow walls 3 and 4 cooled in the same way are moved between the wide side walls 1 and 2 with the help of spindles 8.
    The wide side walls 1 and 2 to their center form an expanded funnel-shaped zone 9, into which the pipe 10 is lowered to supply liquid steel.

    A pipe shell 11, solidified in zone 9, is formed when it is lowered into the tape. To reduce the bending stresses, the side portions of the funnel-shaped zone are made in the form of rectangular transition surfaces 12 with corner points A, B, C and D. The transition to the format defining lower portions of the wide side walls occurs on the horizontal lines C-D. The contour of the transition surfaces 12 is formed by straight lines g, which connect the points AB and CD lines that are located one above the other vertically and which, depending on the position, are under the decreasing angle from 10 to 0 ° (figure 6) to the format-determining bottom wide side walls 1 and 2. The opening angle A of the funnel zone decreases towards the exit from the mold to 0 on the CD line. 5, a contour of transition surfaces 12 is formed.
    straight lines g, which connect point C radially with each point of the horizontal line A-B, and vertical lines B - D, the angle 3 expand from the diagonal position of the straight g to the parallel position with the line C1-P to 0. The upper edge of the funnel-shaped zone 9 is made in the form of an arc (figure 3). According to FIG. The 6 vertical transition surfaces 12 along the arc transform into the format definition of the lower parts of the wide side walls 1 and 2.
    Example. The mold for continuous casting of steel tape has a height of 1100 mm, a width of 1200 mm, a width of a funnel zone 900 mm, a height of 750 mm, a maximum opening width of the funnel zone 170 mm, the forming angle 10e,
    The opening angle is 4.6 e, the width of the transition surfaces is 350 mm, and the distance between the wide sides of the walls at the exit of the mold is 50 mm.
    When casting in the mold, a reduction in tensile bending of the preform shell in the zone of transitional surfaces is achieved, which ensures a favorable distribution of the melt in the steel in the direction of narrow side walls; parallel sections, which reduces the wear of the walls of the mold and improves the quality of cast steel billets of thin sheet format.
