After years of technological updates, non-ferrous metal alloys have developed their properties to the greatest extent.

The grain refinement of the alloy requires a grain refiner, so by improving the performance of the refiner to improve the grain refinement effect of the non-ferrous metal alloy, and then improve the performance of the alloy.

The existing refining agent preparation system is mainly to continuously cast a rod with a larger diameter through a continuous casting device, and then undergo multiple passes of repeated extrusion deformation or rolling to realize the dispersion of heterogeneous nucleation particles in the refining agent Uniformity, but this method cannot solve the problem of large heterogeneous nucleation particle size.

To this end, the embodiments of the present disclosure provide a continuous casting device and a refining agent preparation system, which can realize the dispersibility and fineness of heterogeneous nucleation particles in the refining agent, and can form efficiently and continuously at one time.

To keep the following description of the embodiments of the present disclosure clear and concise, detailed descriptions of known functions and known components may be omitted. When any part of an embodiment of the present disclosure appears in more than one drawing, the part may be represented by the same reference numeral in each drawing.

Fig. 1 is a front view of the continuous casting device provided by the embodiment of the present disclosure, Fig. 2 is a schematic diagram of the overall structure of the continuous casting device provided by the embodiment of the present disclosure, Fig. 3 is a schematic structural diagram of the initial state of the floating assembly provided by the embodiment of the present disclosure, FIG. 4 is a schematic structural diagram of a floating assembly provided by an embodiment of the present disclosure in a floating state, and FIG. 5 is a schematic structural diagram of a floating assembly provided by an embodiment of the present disclosure.

As shown in Fig. 1 to Fig. 2, an embodiment of the present disclosure provides a continuous casting device, which is used for continuously casting liquid metal into bars, including a feed part 1 for conveying liquid metal, and also includes a feed part 1 connected to the feed The upper pouring pot 2 of the component 1 is connected with the first electromagnetic oscillation component, the metal liquid flows into the upper pouring pot 2 through the feeding part 1, and the metal liquid in the upper pouring pot 2 is electromagnetically induced by the first electromagnetic oscillation component. Oscillation, wherein the first electromagnetic oscillation component includes a first electromagnetic induction coil 30 wound on the outer periphery of the pouring pot 2 , and the first electromagnetic induction coil 30 can make the metal liquid in the pouring pot 2 electromagnetically oscillate after being energized.

As a liquid collection container, the upper pouring pot often needs to store a certain amount of metal liquid in it. In this process, more and more particles will be precipitated due to the decrease of the temperature of the metal liquid, and at the same time, aggregation will occur, which will lead to The size of the heterogeneous nucleation particles is relatively large, so in the embodiment of the present disclosure, the continuous casting device is opened by the control system, and the liquid metal (aluminum liquid in one embodiment of the present disclosure) is poured into the feeding part 1, and the feeding part 1 1 enters the pouring pot 2, and at the same time, the first electromagnetic oscillation component outside the pouring pot 2 processes the aluminum liquid, disperses and inhibits the aggregation and growth of heterogeneous nucleation particles.

During the production process, due to the temperature drop of the aluminum liquid after pouring and boiling, more and more particles are precipitated, and at the same time aggregation occurs, resulting in a larger size of heterogeneous nucleation particles in the refiner.

For this reason, the embodiment of the present disclosure provides an improved method. The continuous casting device also includes a conveying member 4 connected to the upper pouring pot 2, the conveying member 4 is connected to the lower pouring pot 5, and the lower pouring pot 5 is connected to the second electromagnetic oscillation assembly. The liquid metal that has been electromagnetically oscillated by the first electromagnetic oscillating component is transported to the pouring pot 5 through the conveying member 4 for secondary electromagnetic oscillation through the second electromagnetic oscillating component, wherein the second electromagnetic oscillating component includes a The second electromagnetic induction coil 60 on the outer periphery, after the second electromagnetic induction coil 60 is energized, the metal liquid in the pouring pot 5 electromagnetically oscillates. Specifically, the feeding part 1 and the conveying part 4 in the embodiment of the present disclosure can be flow groove.

The molten aluminum processed by the first electromagnetic oscillation component of the upper pouring pot 2 enters the lower pouring pot 5 along with the conveying part 4, and is vibrated a second time by the second vibration component 60 of the lower pouring pot 5, thereby continuing to disperse and suppress Heterogeneous nucleation particles aggregate and grow.

In the embodiment of the present disclosure, the pouring pot 5 is located below the potting pot 2, one end of the conveying part 4 is connected to the lower part of the potting pot 2, and the other end of the conveying part 4 is located at the opening of the potting pot 5, and the conveying part 4. It is arranged obliquely so that the metal liquid in the upper pouring pot 2 flows into the lower pouring pot 5.

Because in the follow-up processing, the pouring pot 5 needs to be rotated, therefore, the other end of the conveying part 4 is fixed on the opening of the potting pot 5, that is, the upper end of the potting pot 5, so that it will not be caused by the rotation of the potting pot 5. Affecting the entry of molten aluminum, the inclined setting of the conveying member 4 can facilitate the flow of molten aluminum from the upper pouring pot 2 into the lower pouring pot 5 .

In the embodiment of the present disclosure, the lower part of the pouring pot 2 has a first liquid outlet hole 20, and the first end of the conveying member 4 is connected to the first liquid outlet hole 20, and the first liquid outlet hole 20 is movably connected with a floating assembly 7. As the liquid level in the pouring pot 2 continues to rise, the floating assembly 7 gradually disengages from the first liquid outlet hole 20 so that the metal liquid enters the conveying member 4 .

The floating assembly 7 can float the floating assembly 7 only after the buoyancy of the liquid in the pouring pot reaches a certain level. In this way, the molten aluminum in the pouring pot 2 can be fully electromagnetically oscillated before being subjected to The conveying member 4 is conveyed into the pouring pot 5, so as to further disperse and inhibit the aggregation and growth of heterogeneous nucleation particles.

As the liquid level in the pouring pot gradually drops, the floating assembly will fall back. If the floating assembly cannot be reset, it will not be able to block the first liquid outlet hole, causing it to lose its function in the process of being used again.

For this reason, the embodiment of the present disclosure provides an improved way, the limit member 8 is connected between the floating assembly 7 and the first liquid outlet hole 20, so that the floating assembly 7 will not completely break away from the first liquid outlet hole 20, thereby avoiding the When there is less liquid in the pouring pot, the floating component cannot be reset to the initial position when it is not enough to completely float the floating component.

When it is transported into the pouring pot, the liquid level continues to rise, and the buoyancy makes the floating ball 73 gradually move up. Referring to Figure 4, during this process, the base 70 gradually moves up. When the upper wall of the inlet 71 is higher than the first liquid outlet hole 20 , then the inlet 71 located in the middle of the base 70 gradually communicates with the first liquid outlet hole 20, and the metal liquid enters the conveying member 4 from the outlet 72. At the same time, as the area of the inlet 71 exposed to the first liquid outlet 20 increases, the corresponding The outflow velocity of the liquid increases, avoiding the transient electromagnetic oscillation of the metal liquid, therefore, the floating assembly 7 can also play a role in adjusting the outflow velocity as the liquid level increases.

In the embodiment of the present disclosure, the base 70 is preferably a hollow cylinder. This structure can make the force on each surface uniform, so as to ensure the steady rise of the floating ball 73. The entrance 71 is opened in the middle of the base 70. The floating ball can be made of ceramic material. , thereby avoiding a reaction with the metal liquid in the pouring pot, and the inlets 71 may be multiple, and are equally spaced on the outer periphery of the base 70 .

When the liquid level in the pouring pot is higher than the bottom of the first electromagnetic induction coil, the aluminum liquid is fully processed by electromagnetic oscillation, and the inlet 71 gradually communicates with the first liquid outlet hole 20, so that the metal liquid flows out.

During the subsequent processing, the molten aluminum needs to be cooled and solidified on the crystallization wheel. During this period, a large number of particles will precipitate and grow.

For this reason, the embodiment of the present disclosure provides an improved method, which also includes a crystallization wheel 9 and a steel belt 10 connected to the lower pot 5, so that a mold cavity is formed between the crystallization wheel 9 and the steel band 10, and the lower part of the lower pot 5 There is a second liquid outlet hole, through which the metal liquid is poured into the mold cavity, the crystallization wheel 9 is connected with an ultrasonic generator 11, and the ultrasonic generator 11 generates ultrasonic waves to act on the metal liquid in the mold cavity.

After the molten aluminum enters the mold cavity, the internal cooling system 13 and the external cooling system 14 cool the molten aluminum to accelerate solidification (the cooling medium is water), to ensure that the ingot crystallization is dense and the structure of the core and the edge is uniform. The generator 11 performs ultrasonic treatment to disperse and inhibit the aggregation and growth of heterogeneous nucleation particles. The solidified ingot is separated from the crystallization wheel 9 through the ingot picker 15, and the ingot is led to the subsequent straightening device through the lead bridge 17.
