Description

Technical Field

[0001] The present invention relates to the technical field of metal casting, and in particular to a casting system and application of the casting system in casting deformed aluminum alloy products or deformed magnesium alloy products. Background Art

[0002] Aluminum (magnesium) alloys are divided into two categories according to their forming methods: cast aluminum (magnesium) alloys and deformed aluminum (magnesium) alloys. Among them, cast aluminum (magnesium) alloys are difficult to process and form under external forces such as extrusion force, forging force, and spinning force. Therefore, liquid casting is generally used for forming. However, even after heat treatment, the mechanical properties of the cast workpiece are still unsatisfactory. However, since cast aluminum (magnesium) alloys have excellent liquid fluidity, they can be directly made into workpieces through the casting process, which can avoid a lot of mechanical processing and have low production costs.

[0003] The liquid fluidity of deformed aluminum (magnesium) alloy is poor. During the solidification process, it solidifies at a speed of milliseconds when it is close to the solidus temperature. It is difficult to cast using the current casting system, so external force molding is generally used. However, the use of external force molding requires a lot of mechanical processing to obtain the final workpiece, which has high production costs and low efficiency. However, the workpiece has excellent mechanical properties, and under the same component conditions, its mechanical properties can still be improved or strengthened by heat treatment.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In addition, the terms "include", "comprises" and any variations thereof are intended to cover non-exclusive inclusions.

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] See first Figure 1 and Figure 2 , which shows an exemplary embodiment of a casting system according to the present invention. The casting system comprises an induction melting furnace 1, a casting mold 2, a fluid communication channel 3, and a heating device.

[0050] The induction melting furnace 1 comprises a furnace body 4, which is generally barrel-shaped, and the middle of which is concave to form a containing chamber for containing metals, such as deformed aluminum alloy, deformed magnesium alloy, etc. It should be understood that the furnace body 4 can also be designed into other suitable shapes.

[0051] The induction melting furnace 1 further comprises a first induction coil 5, which is wound around the outer periphery of the furnace wall 11 of the furnace body 4. When the containing chamber is provided with metal, the first induction coil 5 is connected to an external power source, and generates an alternating current in the metal in the containing chamber, so that the metal is heated and melted. After the metal in the containing chamber is heated and melted, the first induction coil 5 continues to be connected to an external power source, and the molten metal (i.e., the metal in a molten state) is in the magnetic field generated by the first induction coil 5, and rotates under the action of the Lorentz force, which has an effect on some components in the molten metal, such as It disperses the fibers and particle agglomerates and homogenizes the components of the molten metal.

[0052] Preferably, the current inputted by the external power supply to the first induction coil 5 is adjustable, such as turning the power supply on and off, changing the direction of the current, changing the frequency of the current, changing the magnitude of the current, etc. For example, the current inputted by the external power supply to the first induction coil 5 is adjusted by a controller. The change of the current will cause the Lorentz force exerted on the molten metal to change accordingly. The sudden disappearance, change of direction, change of magnitude, etc. of the Lorentz force will affect the flow of the molten metal in the containing chamber, break up the fiber and particle agglomerates in the molten metal, and make the components of the molten metal tend to be uniform.

[0053] After the components of the molten metal in the receiving chamber are homogenized to meet the requirements, the molten metal flows from the receiving chamber of the furnace body 4 to the cavity of the casting mold 2 through the fluid communication channel 3. During the filling process, the temperature of the molten metal in the fluid communication channel 3 and the cavity of the casting mold 2 is maintained by the heating device to avoid the molten metal cooling and filling, or cooling and filling with a large temperature difference. Of course, before filling, the fluid communication channel 3 and the casting mold 2 can also be heated to increase their temperature to reduce or avoid the temperature change caused by the molten metal contacting the inner wall of the fluid communication channel 3 and the inner wall of the casting mold 2.

[0054] Specifically, the heating device includes a second induction coil 6, which is surrounded by the outer peripheral side of the fluid communication channel 3 and the outer peripheral side of the casting mold 2. When the molten metal in the accommodation chamber is filled through the fluid communication channel 3, the second induction coil 6 is connected to an external power supply and generates an alternating current in the fluid communication channel 3 and the molten metal in the cavity to provide heat to the molten metal and maintain the temperature of the molten metal. At the same time, since the molten metal is in the magnetic field generated by the second induction coil 6, it rotates under the action of the Lorentz force, which can better homogenize the components of the molten metal and promote filling.

[0055] In an alternative embodiment, the heating device can also be a device that provides heat to the fluid connecting channel 3 and the molten metal in the cavity by means of heat transfer, radiation heating, etc., or a device that provides heat to the fluid connecting channel 3 and the molten metal in the cavity by means of a combination of two or more methods such as heat transfer, radiation heating, electromagnetic induction heating, etc.

[0056] In this embodiment, the induction melting furnace 1 further includes a spoiler 7. The spoiler 7 is arranged in the middle of the accommodation chamber, and its outer peripheral wall includes a first spiral protrusion 8. The molten metal in the accommodation chamber rotates under the action of the Lorentz force, and is turned upward or downward under the guidance of the first spiral protrusion 8, so that the molten metal forms an annular longitudinal turbulence, which can break up the fiber and particle agglomerates in the molten metal and make the components of the molten metal tend to be uniform. It should be understood that the first spiral protrusion 8 can be a continuous spiral protrusion, or it can be formed by a plurality of separate protrusions.

[0057] In this embodiment, the inner peripheral wall of the accommodation chamber includes protrusions 9. The molten metal can rotate turbulently under the action of the Lorentz force. The molten metal flowing through the protrusions 9 of the inner peripheral wall collides with the protrusions 9, thereby forming turbulence, which further breaks up the fiber and particle agglomerates in the molten metal and makes the composition of the molten metal tend to be uniform. The protrusions 9 of the inner peripheral wall can be regularly distributed or irregularly distributed. In this embodiment, the protrusions 9 of the inner peripheral wall are regularly distributed.

[0058] Specifically, the furnace body 4 includes a furnace bottom 10 and a furnace wall 11, and the furnace wall 11 is formed by stacking a plurality of furnace wall 11 units. The space surrounded by the furnace bottom 10 and the furnace wall 11 forms the accommodation chamber. The protrusions 9 of the inner peripheral wall are arranged on the inner wall of the furnace wall 11 unit, and the protrusions 9 between adjacent furnace wall 11 units are staggered, such as Figure 3 shown.

[0059] Now back to Figure 1 and Figure 2 The fluid communication channel 3 includes a drainage channel 12 communicating with the receiving chamber, which is arranged at the furnace bottom 10 and is used to discharge the molten metal in the receiving chamber. The fluid communication channel 3 also includes a flow channel 13 connecting the output end of the drainage channel 12 and the input end of the cavity. The induction melting furnace 1 also includes a plug 14, which is used to adjust the flow of molten metal in the drainage channel 12, such as Figure 1 As shown, the molten metal is blocked from flowing out of the drainage channel 12, and as shown Figure 2 As shown, the molten metal is allowed to flow out of the drainage channel 12. Of course, the flow rate of the molten metal flowing out of the drainage channel 12 can also be adjusted. In this embodiment, the lower end of the plug 14 can move up and down in the drainage channel 12. Therefore, the plug 14 can also exert a force on the molten metal in the fluid communication channel 3. The molten metal can be filled in the gravity continuous casting under isostatic and isothermal conditions, providing good thermodynamic and kinetic conditions for its shrinkage compensation and exhaust.

[0060] Specifically, the spoiler 7 further includes a fluid channel 15 and a mounting hole. The drainage channel 12 is connected to the accommodation chamber via the fluid channel 15. The mounting hole and the drainage channel 12 are located on the same vertical axis, and the plug 14 is plugged into the mounting hole and can move up and down along the axis of the mounting hole to adjust the flow of molten metal in the drainage channel 12 and exert force on the molten metal in the fluid communication channel 3.

[0061] In this embodiment, the furnace body 4, the spoiler 7, and the plug 14 are all made of insulating materials, or materials with very low conductivity at a temperature below the melting point of the provided metal, such as zirconium ceramic materials, aluminum titanate ceramic materials, corundum ceramic materials, etc. The eddy current generated by the current passing through the first induction coil 5 can all act on the metal provided in the accommodation chamber, so the heating efficiency is high, and at the same time, the stirring effect of the Lorentz force on the molten metal in the accommodation chamber can be strengthened, thereby improving the uniformity of the molten metal components.

[0062] The casting system further includes a cooling device 16, which includes a plurality of nozzles (not shown in the figure), and a cooling fluid, such as air, steam, nitrogen, etc., is directly sprayed on the casting mold 2 to reduce the temperature of the metal in the cavity and promote condensation. In an alternative embodiment, the cooling device 16 can also be a device using water cooling, a combination of water cooling and air cooling, or other cooling methods.

[0063] The casting system further includes an ultrasonic source 17, which is on the outside of the casting mold 2 or in contact with the bottom of the casting mold 2. The ultrasonic source 17 is a transducer that converts electrical signals into ultrasonic waves. The ultrasonic source 17 transmits ultrasonic waves to the metal in the mold cavity to promote grain refinement.

[0064] In this embodiment, the casting system integrates smelting and casting molding. The molten metal directly enters the casting mold from the accommodating chamber of the furnace body through the fluid communication channel, and the temperature of the molten metal in the fluid communication channel and the mold cavity is maintained by a heating device. The molten metal can be gravity casted and filled under isostatic and isothermal conditions. Moreover, the casting system can also realize centrifugal continuous casting. The casting system can solve the problem of cooling and filling during aluminum (magnesium) alloy casting at home and abroad, and is suitable for casting deformed aluminum alloy products and deformed magnesium alloy products.

[0065] In another embodiment, the induction melting furnace 1 can also be used as follows Figure 4 and Figure 5 The structure of the induction melting furnace 1 includes a furnace body 4 , a first induction coil 5 , and a spoiler 7 .

[0066] The furnace body 4 is generally barrel-shaped, and includes a furnace bottom 10 and a furnace wall 11. The space surrounded by the furnace bottom 10 and the furnace wall 11 forms a containing chamber for containing metals, such as deformed aluminum alloys, deformed magnesium alloys, etc. In this embodiment, the induction melting furnace 1 also includes a furnace cover 18, and the furnace cover 18 can close the upper end opening of the containing chamber, so that the containing chamber becomes a closed or correspondingly closed space. It should be understood that the furnace body 4 can also be designed into other suitable shapes.

[0067] The first induction coil 5 is wrapped around the outer circumference of the furnace wall 11 of the furnace body 4. When the containing chamber is provided with metal, the first induction coil 5 is connected to an external power source and generates an alternating current in the metal in the containing chamber, so that the metal is heated and melted. The molten metal rotates turbulently in the magnetic field generated by the first induction coil 5 under the action of the Lorentz force, which affects some components in the molten metal, such as It disperses the fibers and particle agglomerates and homogenizes the components of the molten metal.

[0068] The current inputted by the external power supply to the first induction coil 5 is adjustable, such as turning the power supply on and off, changing the direction of the current, changing the frequency of the current, changing the magnitude of the current, etc. For example, the current inputted by the external power supply to the first induction coil 5 is adjusted by the controller. The change of the current will cause the Lorentz force exerted on the molten metal to change accordingly. The sudden disappearance, change of direction, and change of magnitude of the Lorentz force will affect the flow of the molten metal in the containing chamber, break up the fiber and particle agglomerates in the molten metal, and make the composition of the molten metal tend to be uniform.

[0069] The spoiler 7 is arranged in the middle of the accommodation chamber, and its outer peripheral wall includes a first spiral protrusion 8. The molten metal rotates under the action of the Lorentz force and is turned upward or downward under the guidance of the first spiral protrusion 8, so that the molten metal forms an annular longitudinal turbulence, which can break up the fiber and particle agglomerates in the molten metal and make the composition of the molten metal tend to be uniform. It should be understood that the first spiral protrusion 8 can be a continuous spiral protrusion or can be formed by a plurality of separate protrusions.

[0070] Specifically, the spoiler 7 includes a spoiler portion 19, and the first spiral protrusion 8 is arranged on the outer peripheral wall of the spoiler portion 19; the spoiler portion 19 passes through the through hole on the furnace cover 18 and is inserted into the positioning hole at the center of the bottom of the accommodation chamber. The spoiler 7 also includes a flange connection portion 20, the upper end of the spoiler portion 19 is connected to the flange connection portion 20, and is fixedly connected to the furnace cover 18 through the flange connection portion 20.

[0071] In this embodiment, the inner peripheral wall of the containing chamber includes a second spiral protrusion 21. The molten metal rotates turbulently under the action of the Lorentz force, and is turned upward or downward under the guidance of the second spiral protrusion 21, so that the molten metal forms annular longitudinal turbulence, which can break up the fibers and particle agglomerates in the molten metal and make the components of the molten metal tend to be uniform. Preferably, the second spiral protrusion rotates in the opposite direction to the first spiral protrusion. When the first spiral protrusion 8 guides the molten metal to turn upward, the second spiral protrusion 21 guides the molten metal to turn downward; when the first spiral protrusion 8 guides the molten metal to turn downward, the second spiral protrusion 21 guides the molten metal to turn upward. Therefore, the annular longitudinal turbulence promoted by the first spiral protrusion 8 and the annular longitudinal turbulence promoted by the second spiral protrusion 21 produce a longitudinal intersection. At the same time, under the action of the Lorentz force, the molten metal at the intersection can form a complex turbulence, which further homogenizes the fibers and particle agglomerates in the molten metal. Likewise, the second spiral protrusion 21 may be a continuous spiral protrusion, or may be formed by a plurality of separate protrusions.

[0072] The furnace bottom 10 is provided with a drainage channel 12 communicating with the receiving chamber for discharging the molten metal in the receiving chamber. The induction melting furnace 1 also includes a plug 14 for regulating the flow of the molten metal in the drainage channel 12. Figure 4 As shown, the molten metal is blocked from flowing out of the drainage channel 12, and as shown Figure 5 As shown, the molten metal is allowed to flow out of the drainage channel 12. Of course, the flow rate of the molten metal flowing out of the drainage channel 12 can also be adjusted. In this embodiment, the lower end of the plug 14 can move up and down in the drainage channel 12. Therefore, the plug 14 can also exert a force on the molten metal in the fluid communication channel 3. The molten metal can be filled in the gravity continuous casting under isostatic and isothermal conditions, providing good thermodynamic and kinetic conditions for its shrinkage compensation and exhaust.

[0073] Specifically, the spoiler 7 further includes a fluid channel 15 and a mounting hole. The drainage channel 12 is connected to the accommodation chamber via the fluid channel 15. The mounting hole and the drainage channel 12 are located on the same vertical axis, and the plug 14 is plugged into the mounting hole and can move up and down along the axis of the mounting hole to adjust the flow of molten metal in the drainage channel 12 and exert force on the molten metal in the fluid communication channel 3.

[0074] In this embodiment, the induction melting furnace 1 further includes a gas channel 22 for connecting the containing chamber and an external gas source. Specifically, the gas channel 22 is disposed in the plug 14 and can be connected to the fluid channel 15. Figure 4The output end of the external gas source is connected to the inlet of the gas channel 22 at the upper end of the plug 14, and the gas channel 22 is in Figure 4 When the chamber is in the state of being connected to the fluid channel 15, a non-reactive gas such as an inert gas can be introduced into the chamber, or a reactive gas such as oxygen can be introduced into the chamber, or a gas and nano-metal powder can be introduced into the chamber.

[0075] Preferably, the fluid channel 15 is arranged near the bottom wall of the accommodation chamber. On the one hand, the input gas can cause the molten metal to form turbulence at the bottom of the accommodation chamber, further homogenizing the fibers and particle agglomerates in the molten metal; on the other hand, the bubbles generated by the input gas meet the suspended slag during the floating process, and the slag is adsorbed on the surface of the bubbles and brought to the surface of the molten metal, which can effectively remove the slag; on the other hand, when the input gas is an inert gas, it can effectively remove oxygen and water molecules above the surface of the molten metal.

[0076] In this embodiment, the furnace body 4, spoiler 7, plug 14, and furnace cover 18 are all made of insulating materials, or materials with very low conductivity at a temperature below the melting point of the provided metal, such as zirconium ceramic materials, aluminum titanate ceramic materials, corundum ceramic materials, etc. The eddy current generated by the current passing through the first induction coil 5 can all act on the metal provided in the accommodation chamber, so the heating efficiency is high, and at the same time, the stirring effect of the Lorentz force on the molten metal can be strengthened, thereby improving the uniformity of the molten metal components.

[0077] In an alternative embodiment, the casting system further comprises a device for delivering non-reactive gas to the containing chamber, wherein an output end of the device is connected to an inlet of the gas channel 22 at the upper end of the plug 14 .

[0078] In another alternative embodiment, the casting system further comprises a device for delivering reactive gas to the containing chamber, wherein an output end of the device is connected to an inlet of the gas channel 22 at the upper end of the plug 14 .

[0079] The above-mentioned embodiments only express some implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
