Definitions
- the object of the invention is, based on the known method of conductive influencing of a metallic casting strand with simple means and low operating costs, to produce a stirring movement in the strand which is particularly advantageous for horizontal continuous casting, with the aid of which the metal, preferably iron and steel and their alloys, can be produced a force is exerted which acts on the solidifying material particles, in particular globolites, in the circumferential direction and segregates them as homogeneously as possible.
- FIG. 1 shows a horizontal continuous casting installation in a schematic side view
- Figure 2 shows the arrangement of the permanent magnets in an enlarged view
- Figure 3 different embodiments for the iron rings to be arranged between the permanent magnets.
- the horizontal continuous casting plant for steel strands shown schematically in FIG. 1 usually consists of a feed container 8 filled with melt, to which the mold 9, in which the strand is formed, adjoins.
- the strand 2 which begins to solidify in the mold from the outside, is passed through a permanent magnet system arrangement 3 while it still has a liquid or pasty inner region. The further movement of the solidified strand 2 takes place with the aid of a conventional drawing machine 10.
- a direct voltage generated in the arrangement 1 is applied to the strand 2 at 4.
- there is a stirring movement which causes the globolites to separate or to equalize the strand by preventing segregation.
- the permanent magnet system consists of the magnets concentrically surrounding the circular strand 2, which are magnetized axially, in such a way that the north pole is located on one and the south pole on the other annular end face of the permanent magnets .
- Two successive magnets of the arrangement are oriented opposite each other.
- iron rings or disks 5 are provided, which, as explained in FIG. 3, are designed by radially extending cross-sectional conditions such that they are caused by the circumferential magnetic field are not magnetically saturated by the current flowing in strand 2.
- the magnetic resistance in the iron rings or disks 5 can also be increased by appropriate air gaps.
- Both the permanent magnets and the iron rings or disks are expediently divided into segments along radially running surfaces.
