    • The present invention relates to a process and apparatus for the recovery of liquid aluminium by compression of hot dross.The process comprises placing the dross in a die up to a height which depends on the diameter of said die and which is lower at the center than at the periphery of the die, and then applying to the dross a punch which is moved downwardly at a speed which is lower in proportion to a lower level of concentration of liquid aluminium in the dross.The apparatus comprises a cylindrical die (10) provided with an insert member at each of its ends. The die rests on a base (3) which has an annular groove (4) on its upper face; the lower insert member (7) is of a diameter that is at least equal to the inside diameter of the groove and in any case less than the outside diameter and has a continuous upper face of conical shape; the space (16) between the wall surface of said insert member and the internal wall surface of the die is of a constant width and is disposed facing the groove.The invention is used in the aluminium industry when there is a need to treat dross in an economical fashion and under good conditions in regard to health.
    • 本发明涉及通过热浮渣压缩回收液态铝的方法和装置。 该方法包括将锌渣放置在模具中,直到取决于所述模具的直径并且在中心处比模具的周边处更低的高度,然后向浮渣施加向下移动的冲头 与渣中液态铝浓度较低的比例较低的速度。 该装置包括在其每个端部处设置有插入构件的圆柱形模具(10)。 模具搁置在其上表面上具有环形凹槽(4)的基部(3)上; 所述下插入件(7)的直径至少等于所述槽的内径,并且在任何情况下小于所述外径,并且具有圆锥形连续的上表面; 所述插入构件的壁面与模具的内壁面之间的空间(16)具有恒定的宽度并且面向凹槽设置。 当需要以经济方式处理浮渣并且在健康状况良好的条件下,本发明用于铝工业。
