Description

Technical Field

[0001] This invention relates to the field of magnesium alloy casting technology, specifically to a flow distribution device and gating system for casting magnesium alloy plates. Background Technology

[0002] Magnesium alloys, as lightweight and high-strength metallic materials, have a wide range of applications and have been widely used in aerospace, automotive, biomedicine, and 3C products in recent years. With the expansion of magnesium alloy applications, higher requirements are being placed on the quality of magnesium alloy products. In the semi-continuous casting production process of magnesium alloy materials, the flow rate and temperature field distribution of the alloy liquid have a significant impact on the quality of magnesium alloy products. Therefore, flow control and temperature field monitoring and adjustment during the casting of magnesium alloy molten metal in industrial production can ensure the stability of the production process and the quality of the products.

[0003] However, traditional manifolds have the following drawbacks in the production of large-format, wide-width magnesium alloy cast plates (400×1200mm):

[0004] 1. Traditional distribution plates have fixed and unadjustable flow rates through their distribution orifices. When the molten metal enters the distribution plate from the pipette, the flow velocity differs between the edge and center regions due to variations in the position of the distribution orifices, easily leading to uneven flow and flow deviation. When the temperature or viscosity of the molten metal fluctuates, the slower flow velocity at the edge compared to the center results in a noticeable "thinning" phenomenon at the edge of the cast billet (thinner than the center).

[0005] 2. In the traditional distribution plate production process, it is impossible to monitor the temperature field distribution when the melt flows out of the distribution plate. When the temperature field distribution is uneven, it will cause the cooling rate difference at different locations to be too large. It is impossible to adjust the dynamic balance of the temperature field distribution by changing the melt outflow rate according to the temperature difference at different locations.

[0006] 3. Traditional distribution plates have a flat bottom design, resulting in a large contact area with the "liquid cavity" formed by the magnesium alloy melt in the crystallizer. The melt tends to stagnate at the interface between the flat surface and the liquid cavity, and the melt impacts the distribution plate when it enters, leading to severe localized oxidation. Furthermore, the flat structure cannot conform to the curved surface of the liquid cavity, hindering melt flow, making pouring control difficult, and resulting in poor uniformity of the cast billet thickness. Summary of the Invention

[0007] To address the problems existing in the prior art, this invention provides a flow divider and gating system for casting magnesium alloy plates, which solves the problems of the traditional flow divider having an unadjustable melt flow rate, difficulty in monitoring the temperature field distribution, easy flow deviation, and excessively large differences in cooling rates, as well as the problem that the traditional flow divider's bottom surface is designed as a flat surface, which is prone to oxidation and is not conducive to matching with the liquid cavity.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] A flow distribution device for casting magnesium alloy plate includes a flow distribution plate 10, a liquid distribution funnel 14, a horizontal moving device, a temperature measuring device, and a gate mechanism.

[0038] The distribution plate 10 has a distribution cavity, and a temperature measuring device is installed in the distribution cavity to obtain the temperature of the magnesium liquid at different positions in the distribution cavity. The side wall of the distribution cavity is provided with multiple guide holes 5, and the magnesium liquid in the distribution cavity flows out through the guide holes.

[0039] The horizontal moving device includes a guide rail 11 and a slide bar 13; the guide rail is fixed to the top of the distribution plate, multiple slide bars are connected to the guide rail and can move along the axial direction of the guide rail, the slide bars are connected to the first driving device, the driving device is located outside the distribution plate, and the liquid separating funnel 14 is set in the distribution cavity and connected to the slide bar and moves synchronously.

[0040] The gate mechanism includes a gate and a second driving device. The gate is movably mounted on the side wall of the diversion chamber and covers part of the guide hole. The gate is connected to the second driving device, which can drive the gate 17 to move up and down to open and close the guide hole corresponding to the gate.

[0041] In some embodiments, the distribution plate is a rectangular shell structure with an open top surface. The shell has a uniform wall thickness, and multiple guide holes are set at the same height on the side wall of the distribution plate. The guide holes are circular holes, and straight groove guide holes 6 are provided at the corners of the distribution plate. Molten magnesium liquid in the distribution plate flows out uniformly through the guide holes.

[0042] In some embodiments, the lower part of the outer wall of the distribution plate is provided with an inclined guide surface, the lower end of which is inclined toward the center of the distribution plate. After the magnesium liquid flows out from the guide hole, it flows along the outer wall and the guide surface under the action of gravity, which solves the problem of magnesium liquid oxidation and the difficulty in matching with the liquid cavity.

[0043] The lower end of the outer wall of the manifold is inclined, and the symmetrical inclined surfaces on both sides form a V-shaped structure. This reduces the contact area with the "liquid cavity" formed by the magnesium alloy melt in the crystallizer. The V-shaped structure better conforms to the curved surface structure of the "liquid cavity" during the solidification process. This structure helps stabilize the melt flow, improves the depth distribution of the liquid cavity, and avoids problems such as cold shuts and cracks in the ingot caused by excessively deep liquid cavities or excessive temperature gradients. It also facilitates the control of the stability of the casting process. The melt is less likely to stagnate at the interface between the V-shaped structure plane and the liquid cavity. Moreover, the melt impacts the manifold when it enters it; the V-shaped structure reduces this impact, minimizes surface agitation, and reduces oxidation.

[0044] In some embodiments, the function of the temperature measuring device is to monitor the temperature of the magnesium liquid at different locations in the distribution plate in real time. The temperature measuring device includes a thermometer 4, a temperature measuring tank 3, and a temperature display 7.

[0045] Multiple temperature measuring tanks are spaced apart in the flow distribution chamber. Each temperature measuring tank 3 is equipped with a thermometer, which is connected to a temperature display. The temperature data collected by the thermometer is displayed on the temperature display.

[0046] Optionally, multiple temperature measuring tanks 3 are fixed to the inner wall of the distribution plate and the horizontal moving device respectively, and the height of the multiple temperature measuring tanks is the same to ensure the consistency of the measured temperature data.

[0047] The temperature measuring chamber is a high-temperature resistant metal mesh structure. The thermometer is placed in the mesh to prevent it from shaking and to ensure that the thermometers are at a consistent height.

[0048] In some embodiments, the horizontal moving device includes a guide rail 11 and a slide bar 13; two guide bars are arranged parallel to each other and spaced apart on the top of the separation disk, and the two ends of the guide bars are connected to the top of the separation disk through fixed posts.

[0049] Slide rods 13 are respectively fitted at both ends of the guide rail. The slide rods 13 are provided with axial clearance grooves to avoid the fixed column, so that the slide rods can move along the guide rail. A separating funnel 14 is provided between the two slide rods at the same end of the guide rail. The top of the separating funnel is fixed to the end of the slide rod through a connecting rod, so that the slide rod and the separating funnel move synchronously, thereby controlling the distance between the two separating funnels.

[0050] Optionally, the first drive device is a cylinder or an electric push rod;

[0051] For example, the cylinder rod of the cylinder is connected to the end of the slide rod. The cylinder controls the movement of the cylinder rod, which in turn drives the separating funnel to move through the slide rod. The cylinder body is fixed outside the distribution plate. The cylinder rod and the slide rod are arranged in parallel. The ends of the two slide rods are connected by a crossbar. The middle part of the crossbar is connected to the end of the cylinder rod, so that one cylinder can drive the two slide rods to move synchronously.

[0052] Optionally, a connecting rod 16 is provided between the two guide rails, and a temperature measuring groove is provided on the connecting rod; a connecting rod is provided between the two slide rods, and a temperature measuring groove is provided on the connecting rod.

[0053] By setting multiple temperature measuring points on the side wall of the distribution plate, between the guide rails, and between the slide rods, multi-point temperature measurement of the distribution plate can be achieved, so as to better monitor the temperature of the magnesium liquid.

[0054] In some embodiments, the gate mechanism is disposed on the side wall of the diversion plate, and a horizontal fixing plate is disposed on the top of the diversion plate. A straight groove 20 is disposed on the fixing plate. The length of the straight groove 20 is greater than that of the gate, and the width is the same as that of the gate. The gate is vertically disposed in the straight groove, extends downward and covers the inner wall of the diversion plate, and covers the guide hole in this area. A cylinder is disposed on the top of the fixing plate, and a protective shell is disposed on the outside of the cylinder to insulate and protect the cylinder. The cylinder rod passes through the protective shell and is connected to the gate. The cylinder drives the gate to move up and down, thereby realizing the opening and closing of the guide hole in the gate area.

[0055] See Figure 1 The separation disc has three gate mechanisms on each side.

[0056] In some embodiments, the separating funnel has a barrel-shaped structure with an upwardly extending cone at its bottom, and the surface of the cone is inlaid with hard alloy.

[0057] Example 1

[0058] See Figure 1-3 A flow divider cast from a magnesium alloy cast plate includes a horizontal moving device 1, a gate structure 2, a temperature measuring tank 3, a thermometer 4, a circular guide hole 5, a straight groove guide port 6, a temperature display 7, a pneumatic control device 8, an air storage tank 9, and a V-shaped chassis flow divider 10.

[0059] The horizontal moving device includes a guide rail 11, a slide bar 13, and a separating funnel 14;

[0060] Two guide rails 11 are arranged parallel to each other and spaced apart on the top of the distribution plate. Slide rods 13 are coaxially sleeved at both ends of the guide rails 11 and can slide along the guide rails 11. A fixing ring 15 is welded between the ends of the two slide rods 13. The fixing ring 15 is welded to the top edge of the separating funnel 14 through a connecting column. The interior of the separating funnel 14 is provided with an upwardly protruding cone. The surface of the cone is inlaid with ceramic patches to increase the erosion resistance. The end of the slide rod 13 is connected to the cylinder rod of the cylinder.

[0061] In this embodiment, a total of 13 temperature measuring points are set. Five temperature measuring points are set at intervals on the side wall of the long side of the distribution plate, that is, five temperature measuring grooves are set. The top of the temperature measuring groove is connected to the top interior of the distribution plate. A connecting rod 16 is set in the middle of the two guide rails, and a temperature measuring groove is set in the middle of the connecting rod. An arc-shaped rod 12 is set between the ends of the two sliding rods, and a temperature measuring groove is set at the midpoint of the arc of the arc-shaped rod 12. The temperature measuring groove moves synchronously with the sliding rod and the liquid separating funnel.

[0062] The gate mechanism 2 includes a gate 17, a cylinder 18, an air pipe 19, and a straight groove 20;

[0063] The top of the diversion plate is provided with an inwardly extending horizontal fixing plate. The horizontal fixing plate and the side wall of the diversion plate are integrally bent and formed. Multiple circular guide holes are provided on the side wall of the diversion plate, and straight groove guide holes are provided at the corners. The area of ​​the outer wall of the diversion plate 10 that contacts the liquid cavity is an inclined surface, and the lower end of the inclined surface is inclined towards the center of the diversion plate.

[0064] Three straight slots 20 are symmetrically arranged on the horizontal fixed plates of the two long sides of the diverter plate 10. The three straight slots 20 are spaced apart. A gate plate 17 is installed in the straight slot 20. A cylinder is fixed to the top of the horizontal fixed plate. The top of the gate plate 17 is connected to the cylinder rod of the cylinder 18. The cylinder 18 controls the gate plate to move up and down in the straight slot. The air inlet of the cylinder 18 is sealed to the air outlet of the air tank 9 through a pneumatic control device. The pneumatic control device 8 is sealed to the cylinder 18 through an air pipe 19 to control the air flow of each cylinder 18, thereby changing the up and down movement distance of the gate plate 17.

[0065] The pneumatic control device, cylinder, temperature display and drive device are connected to the control unit. The control unit controls the position of the separating funnel and the opening and closing of the guide hole by each gate according to the temperature of each temperature measuring point.

[0066] The following describes the method of using the magnesium alloy cast plate-cast manifold provided in Example 1:

[0067] Step 1: The guide rail 11 is fixed on the top of the distribution plate 10. The slide bar 13 is moved by the cylinder to move the liquid separating funnel 14 to the position specified in the process. The thermometer 4 is placed in the 13 temperature measuring tanks 3 and the temperature display 7 is turned on to monitor the temperature in real time.

[0068] Step 2: Place the pipette outlet onto the separating funnel 14. The magnesium alloy liquid is fed into the separating funnel 14 through the pipette. The separating funnel 14 has an outlet hole on its side wall. After the magnesium alloy liquid flows out, it enters the distribution plate 10. The temperature monitored by the thermometer 4 is displayed on the temperature display 7. The control unit adjusts the movement of the slider 13 to change the distance between the separating funnels 14, so as to achieve the desired temperature of the magnesium alloy liquid in the distribution plate.

[0069] Step 3: When the magnesium alloy solution flows to the circular guide hole 5 on the edge of the distribution plate 10, the control unit operates the pneumatic control device 8 according to the temperature display on the temperature display 7. After receiving the command, the pneumatic control device 8 controls the air pressure of the cylinder 19 to control the up and down movement of the gate 18, thereby changing the opening and closing size of the circular guide hole 5 on the side of the distribution plate 10, and thus controlling the flow rate of the magnesium alloy liquid. By changing the flow rate at different locations, an ideal temperature field distribution is achieved.

[0070] Example 2

[0071] A method for using a flow divider plate cast from a magnesium alloy cast plate includes the following steps:

[0072] Step 1: Before starting the pouring, install the temperature monitoring and flow control parts of the manifold. Place the thermometer in the temperature tank, insert one end of the gate into the straight slot reserved on the manifold, and connect the other end to the cylinder and fix the whole on the side of the manifold.

[0073] Step 2: Install the separatory plate in the working position, adjust the position of the separatory funnel to the position required by the process specifications, and turn on the temperature display to start monitoring temperature changes.

[0074] Step 3: When starting the pouring process, place the outlet of the pipette into the separating funnel. After the magnesium alloy liquid comes out of the pipette, it is first buffered by the conical structure in the separating funnel before entering the distribution plate. It then flows into the crystallizer through the outlet on the side wall of the distribution plate. The temperature field distribution is adjusted in real time according to the temperature display to achieve the ideal process state. If the temperature of the center of the distribution plate is too high or too low as required by the temperature display, the distance between the two separating funnels can be changed to adjust the temperature. If the temperature of a local area on the edge of the distribution plate is too high or too low, the flow rate of the melt at the corresponding position can be changed by controlling the up and down movement of the gate to increase or decrease the temperature, thereby achieving dynamic balance control between the temperature field distribution and the melt flow rate.

[0075] Step 4: After the casting is completed, separate the assembled parts on the new type of distribution plate, and then clean the oxides and other substances on the device. After cleaning, put each component in its corresponding position for standardized management.
