Abstract

1. Устройство для непрерывной разливки прямоугольных стальных слитков, содержащее промежуточный ковш, кристаллизатор с широкими и узкими гранями, глуходонный цилиндрический погруженный разливочный стакан с эксцентрично расположенными выходными отверстиями, поверхность которых выполнена по закону у=8·xn, где x - координата, проходящая через центр стакана параллельно оси выходного отверстия; y - координата, проходящая через внутреннюю поверхность отверстия стакана; n=0,48-0,52, отличающееся тем, что стакан выполнен напорным, в котором площадь проходного сечения центрального канала F1 связана с площадью выходного отверстия F2 соотношением F1/2F2=1,05-1,1, выходные отверстия стакана расположены под углом β=3-8° к вертикальной оси, проходящей через центр погруженного разливочного стакана. ! 2. Устройство по п.1, отличающееся тем, что наружная и внутренняя поверхности дна стакана выполнены конусными и расположены также под углом β=3-8° к вертикальной оси, проходящей через центр напорного погруженного разливочного стакана.1. Device for the continuous casting of rectangular steel ingots, containing an intermediate ladle, a mold with wide and narrow faces, a deep-sea cylindrical submerged casting nozzle with eccentrically located outlet openings, the surface of which is made according to the law y = 8 · xn, where x is the coordinate passing through the center of the cup parallel to the axis of the outlet; y is the coordinate passing through the inner surface of the hole of the glass; n = 0.48-0.52, characterized in that the glass is made pressure, in which the area of the passage section of the Central channel F1 is connected with the area of the outlet F2 with the ratio F1 / 2F2 = 1.05-1.1, the outlet openings of the glass are located under angle β = 3-8 ° to the vertical axis passing through the center of the submerged nozzle. ! 2. The device according to claim 1, characterized in that the outer and inner surfaces of the bottom of the glass are made conical and are also located at an angle β = 3-8 ° to the vertical axis passing through the center of the pressure submerged filling glass.
