Abstract
1. Способ непрерывной разливки прямоугольных стальных слитков, включающий подачу жидкой стали в центре кристаллизатора через погружной разливочный стакан плоскими струями и вытягивание из кристаллизатора слитка, при этом используют стакан с эксцентрично расположенными выходными отверстиями и направленными под углом «α» в сторону широких граней, внутренняя поверхность отверстий которого выполнена по закону у=8·xn, где n=0,48-0,52, х - координата, проходящая через центр стакана параллельно оси выходного отверстия; у - координата, проходящая через внутреннюю поверхность отверстия стакана, отличающийся тем, что подачу жидкой стали в центре кристаллизатора осуществляют плоскими струями параллельно поверхности корочки заготовки под углом β=3-8° к вертикальной оси, проходящей через центр напорного погружного разливочного стакана, в котором площадь проходного сечения центрального канала «F1» связана с площадью одного выходного отверстия «F2» соотношением F1/2F2=1,05-1,1. ! 2. Способ по п.1, отличающийся тем, что в процессе разливки жидкой стали осуществляют поворот разливочного стакана вокруг своей оси по часовой стрелке на угол α'=3-15°.1. The method of continuous casting of rectangular steel ingots, including the supply of liquid steel in the center of the mold through a submersible casting cup with flat jets and pulling the ingot from the mold, using a cup with eccentrically located outlet openings and directed at an angle "α" towards wide faces, inner the surface of the openings of which is made according to the law y = 8 · xn, where n = 0.48-0.52, x is the coordinate passing through the center of the glass parallel to the axis of the outlet; γ is the coordinate passing through the inner surface of the nozzle opening, characterized in that the liquid steel is fed in the center of the mold with flat jets parallel to the surface of the workpiece crust at an angle β = 3-8 ° to the vertical axis passing through the center of the pressure submersible casting nozzle, in which the cross-sectional area of the central channel “F1” is related to the area of one outlet “F2” with the ratio F1 / 2F2 = 1.05-1.1. ! 2. The method according to claim 1, characterized in that during the casting of molten steel, the casting cup is rotated around its axis clockwise by an angle α ′ = 3-15 °.
