The disadvantage of this construction is that the melt stream still drains deeply into the mold pool, so venting occurs in the inner region of the mold pool

Embodiment Construction
[0036] Figure 1 shows a casting system for casting copper strip by using a mold for continuous casting, also called "casting system using a moving mold". After the copper has been melted, the melt passes from the furnace into a tundish 1 , which is equipped with a nozzle 2 in this example. Depending on the width of the copper strip to be cast, the casting nozzle 2 can have several identical immersion tubes 6 , for example 6 , 8 or 10 , which are arranged next to each other at a predetermined casting angle of approximately 10°. The spacing of the individual immersion tubes 6 can vary. The view in FIG. 1 shows only one immersion tube 6 . The immersion tube 6 has cylindrical connectors 7 (see FIG. 2 ), which are cast from refractory concrete as a plug which forms part of the tundish 1 . The mold 3 is located between the movable mold upper belt 4 and the movable mold lower belt 5, wherein the movable mold upper belt 4 and the movable mold lower belt 5 are tensioned by turning pu...

The casting system comprises a tundish connected to at least one or more submerged pipes, wherein the submerged pipes are disposed such that they are inclined to a certain pouring angle, and a first section and a second section comprise tip nozzles(9) of the submerged pipes, the tip nozzles of the submerged pipes are dipped into molten bath in a mold, free ends of the tip nozzles are sealed, at least one or more discharge openings(12) are formed on the wall surface contacted with the bottom surface of the mold, the discharge openings firstly change a flow direction of the molten mass, lips(13,13a) are disposed on the tip nozzles of the submerged pipes such that the lips are overlapped with the discharge openings in the state that the lips are spaced from the discharge openings in a certain distance, the lips secondly change a flow direction of the molten mass and divide the molten mass in an alternate direction when seen from a longitudinal axis of the mold, and the discharge openings and the lips are positioned underneath the surface of the mold bath in the operated state.
Description
technical field [0001] The invention relates to a casting system for casting melts of non-ferrous metals, in particular copper or copper alloys, for the manufacture of flat-plate products and comprising a tundish with at least one immersion tube, preferably inclined Arranged for immersion in a molten pool within a sheet mold; moreover, the invention relates to a casting method. Background technique [0002] Various types and designs of submerged casting tubes for discharging molten metal into molds are well known. Submerged casting tubes are used to ensure an even and gentle distribution of the molten metal into the mold. Also, the use of a immersion tube is used to prevent oxygen in the air from coming into contact with the metal stream below the surface of the molten pool. Under the action of hydrostatic pressure in the tundish, the melt is accelerated to the desired flow rate, and this increase in flow rate depends on the casting angle. In practice, the application of ...
