    In this immersion and vaporization fondery chamber, there is provided in the lower third portion on the side of the handling container as well as in the two upper thirds of the inner wall, an opening. The number, the size and the cross section of the openings are selected so that the total cross section Qu of the opening or openings of the lower third is equal or smaller than the total cross section area Qo of the opening or openings of the two upper thirds. According to a form of execution, the ratio Qo/Qu is at least equal to 2. The application of this chamber is characterized by the incorporation of vaporisable additives in the cast-iron, particularly pure magnesium in a handling container containing puddle bar, cast-iron or steel. The process is appropriate for the disulphurization and/or the production of vermiculated or spheroidal graphite cast-iron and malleable cast-iron.

    2. The capsule according to claim 1, distinguished from the fact that the rod is attached to the lid through the sealing element.
    3. Capsule on PP. 1 and 2, characterized in that it is mounted for rotation or displacement in a pulsed mode.
    4. Capsule on PP. 1-3, that is, the bar is coated inside and outside with a ceramic material.
    5. Capsule on PP. 1-3, that is, the bar is made of ceramic material.
    The invention relates to metallurgy and can be used to treat liquid metals with evaporating additives, such as desulfurization.
    The aim of the invention is to increase the processing efficiency.
    The drawing shows the installation | general view.
    The installation contains a lined ladle 1, for example, a transport ladle filled with 2.chuguSch1I steel melt, into which the chamber 3 for evaporating additives with a rod 4 is placed. be connected to the drive 8 rotation or movement in a pulsating mode. A removable casing 9 may be installed on the bucket. To ensure effective movement of the spraying, the capsule is preferably placed eccentrically relative to the axis of the bucket and / or eccentrically placed the hole 10 in the wall of the chamber. The holes in the chamber wall are located at least at two levels, with the total cross-sectional area of the holes located in the lower third of the chamber less than the total cross-sectional area of the holes located in the upper two-thirds of the chamber wall.

    The rod 4 can be lined partially or along the entire length of the ceramic material outside, inside or on both sides, and can also be made of a material that dissolves in the alloy after completion of metal processing.
    The protective cover 9 may be provided with one or more openings for the separation of the vapor, for which suction pipes, such as flexible metal hoses, are installed.
    The installation works as follows.
    A ladle or other process tank is filled with liquid iron or. steel, covered with a protective casing, through the holes in which a yellow capsule is lowered, the chamber cavity of which through the rod is filled, for example, with magnesium. The rotational and / or oscillatory movement of the immersion capsule ensures optimal vapor transport with the molten metal.
    The increased cross-sectional area of the upper orifices relative to the lower ones increases the processing efficiency by adjusting the steam-, dividing-by height.
    The invention allows desulfurization to regulate the residual magnesium content in the liquid metal.
