Definitions

  • the invention relates to a scooping metering device for fine-metered scooping and metering of variably adjustable melting quantities of metallic melts by means of angular momentum counting or electrical weighing, consisting of metering vessel and discharge funnel, displacement body and adjustment drive with parallelogram guide.
  • the metering vessel is assigned a voltage transmitter with a resistance measuring device, which in turn transmits control impulses for the immersion depth of the metering vessel in the melt.
  • the metering processes are initiated in each of the control types according to the invention by immersing the cylindrical metering container 40 in the melt.
  • the metering vessel 40 is equipped with a downwardly inclined discharge funnel and with lateral openings 43, which can also take the form of a slit.
  • the openings 43 are intended for the inflow of the amount of melt.
  • the displacer piston 44 preferably in a cylindrical shape, is then arranged in the interior of the container containing the melt. When the adjustment drive 30 is actuated, it displaces the predetermined amount of melt very precisely by displacing the volume.
  • a further advantageous possibility of controlling the intervals of the scooping and immersion depth is achieved, as shown in FIG. 3, in that an electrical voltage transmitter 50 is connected to the metering container 40 and is connected to a simple resistance measuring device 51. When immersing and filling the container, the electrical resistance also changes with the height of the immersion depth. A preselected measured value is entered into the resistance measuring device, which switches off the motor lifting drive when the predetermined value, which corresponds to a certain immersion depth, is reached and thus limits the immersion depth and thus the amount of melt flowing out. With this method of operation, optimal scooping positions are achieved and the bath movements are kept as low as possible, thereby avoiding the dreaded air pockets in the end products that lead to complaints.
