Claims (2)

1. Способ рафинирования стали в промежуточном ковше установки непрерывной разливки стали, включающий подачу металла из сталеразливочного ковша в промежуточный ковш и далее в кристаллизатор, подачу в промежуточный ковш теплоизолирующей шлакообразующей смеси, отличающийся тем, что в приемной емкости промежуточного ковша организуют (осуществляют) гашение вихревых потоков (воронок) на поверхности металла путем уменьшения радиальной составляющей скорости течения металла и перераспределения скоростей потоков металла с увеличением их скорости вблизи днища промежуточного ковша и уменьшением скорости вблизи поверхности металлического расплава.1. A method of refining steel in an intermediate ladle of a continuous casting plant, comprising supplying metal from a steel pouring ladle to an intermediate ladle and further to a mold, feeding a heat-insulating slag-forming mixture to the intermediate ladle, characterized in that the vortex quenching is organized (carried out) in the receiving tank of the intermediate ladle flows (funnels) on the metal surface by reducing the radial component of the metal flow rate and the redistribution of metal flow velocities with an increase in their velocity spine near the bottom of the tundish and reduced velocity near the surface of the metal melt. 2. Устройство для рафинирования стали в промежуточном ковше установки непрерывной разливки стали, включающее сталеразливочный ковш, погружную трубу, промежуточный ковш, разделенный на приемную и рафинирующую емкости огнеупорными перегородками с отверстиями различной формы, отличающееся тем, что в донной части приемной емкости промежуточного ковша вдоль его большой оси установлены одна или более примыкающие к боковой стенке промежуточного ковша вставки-вихрегасители, образуя суженный канал в донной части приемной емкости, при этом центр пересечения осей симметрии канала соответствует центральной оси погружной трубы.2. A device for refining steel in an intermediate ladle of a continuous steel casting installation, including a steel pouring ladle, an immersion pipe, an intermediate ladle divided into receiving and refining containers by refractory walls with holes of various shapes, characterized in that in the bottom of the receiving tank of the intermediate ladle along it on the major axis, one or more inserts-eddy suppressors adjacent to the side wall of the intermediate bucket are installed, forming a narrowed channel in the bottom of the receiving tank, while mp intersection of the axes of symmetry of the channel corresponds to the central axis of the dip tube.
