Definitions
- the invention relates to a process for the continuous casting of metal or metal alloys, in particular copper or copper alloys, in which the liquid metal is passed from a heating vessel via a pouring nozzle into the pouring basin of a continuous casting installation which has a moving mold.
- the invention further relates to a casting device for the continuous casting of metals, consisting of a furnace, a device for transferring the molten metal and a moving mold.
- the molten metal is continuously fed to an open tundish and from there in an overflow process to the casting machine.
- This has the disadvantage that the liquid metal comes into contact with air prior to solidification, so that oxygen or hydrogen-affine metal types cannot be cast with it at all.
- Another disadvantage is that, at the end of the casting, a residue of the liquid metal remains in principle in the tundish, which must be disposed of. Emptying the tundish poses a security risk.
- the pouring nozzle for the molten metal is designed as an immersion tube which projects into the pouring basin formed by co-rotating molds.
- this measure is known in principle, there was the view in the other casting processes that, in order to build up a solidification front, the casting nozzle or the nozzle lips had to be arranged relatively close to a lower, cooled conveyor belt according to the desired liquid film thickness To be able to control fluid outflow better.
- DE 37 07 897 AI proposes to adjust the inclination of the conveyor belt in the casting direction as a function of the casting speed and the material parameters of the metal melt in the case of a conveyor belt which is inclined to the horizontal in the casting direction.
- the melt flow can still be controlled even when the inlet mouth of the co-rotating one Chill molds are built into which the dip tube is immersed. This largely prevents contact of the melt with the outside air.
- the flow velocity of the melt and thus the flow profile in the pool can be influenced just as well via the dip tube diameter and the metallostatic pressure set via the bath level in the forehearth as the cooling and solidification profile in the casting pool.
- This profile can be set, for example, via the immersion length of the immersion tube, the shape of the outlet opening and the flow speed, which in turn influence the heat transfer to the mold wall that moves along. Since the cooling with moving molds typically takes place much faster than with oscillating molds, the liquid phase is greatly shortened in time. This means that gravitational effects take a back seat and the flow profile (including backflows) or cooling efficiency become more important.
- the inclination of the dip tube is preferably adapted to the level of the casting mirror and, if necessary, adjusted.
- the idler mold sides are slightly inclined in a further embodiment of the invention relative to the horizontal, 'preferably between 3 ° and 45 °.
- the molten metal is preferably transferred directly from the furnace into the dip tube, preferably under pressure.
- the casting device described in claim 5 is used, which according to the invention is characterized in that the device for transferring the molten metal is an immersion tube which is arranged to be movable along its longitudinal axis. This longitudinal axial mobility is a prerequisite for the immersion tube always being able to be positioned at the desired immersion depth in the casting pool.
- Distance sensors which are arranged on the outer jacket, are preferably used for positioning the immersion tube.
- the distance sensors with a corresponding control ensure that the dip tube is tracked when the casting level changes and that the dip tube is centered in order to maintain the desired flow profile and to prevent thermal short-circuits with accompanying mold components.
- the immersion tube is directly connected to the casting furnace, the furnace being movable along a path inclined to the horizontal, so that the immersion tube can be guided by the movement of the furnace.
- This measure saves intermediate vessels, such as the overflow tundish required by the prior art.
- the otherwise existing inertia of the feed system is eliminated by eliminating the transfer function of the Tundishes from the flow chain reduced.
- a further improvement in the melt flow can be achieved if the dip tube is arranged inclined relative to the longitudinal axis of the casting gap and can be guided. This is ensured by appropriate control elements on the furnace frame, which always bring the furnace into the optimal position with the immersion tube attached to it.
- Fig. 1 is a side view of a casting furnace together with a partial view of two cooled moving mold sides in the form of conveyor belts and
- Fig. 2 is an enlarged view of the dip tube with respect to the pouring pool.
- the casting furnace 10 shown in Fig. 1 is equipped with an inductive heating. From the casting furnace 10 a forearm 11 extends with an inclined bottom surface 12. At the end of the forearm 11 there is an immersion tube 13 which (see in particular FIG. 2) projects so far into the casting gap 14 ' between the two cooled transport rollers 15, 16, that the outlet end of the dip tube 13 is below the casting level 17.
- the entire casting furnace is stored in such a way that the inclination of the dip tube as well as its relative position with respect to the cooled transport rollers 15, 16 is adjustable. Distance sensors and a control device on the dip tube are used for this.
- the casting gap formed by the conveyor belts 15 and 16 is arranged obliquely to the horizontal and runs at least substantially parallel to the longitudinal axis 18 of the dip tube.
