Description
Technical Field
[0001] This utility model relates to the field of magnesium alloy preparation technology, specifically a magnesium alloy workshop. Background Technology
[0002] Magnesium alloys are alloys composed of magnesium as a base and other elements. They have the characteristics and advantages of low density, high strength, high elastic modulus, and good heat dissipation. The main alloying elements of magnesium alloys include aluminum, zinc, manganese, cerium, thorium, and small amounts of zirconium or cadmium. They are widely used in aerospace, automotive industry, electronic and communication equipment, and medical device technology fields. Automated production workshops for magnesium alloys utilize automated equipment, robots, intelligent control systems, and other technologies to realize the entire production process of magnesium alloy materials from raw materials to finished products.
[0003] The defects in the existing magnesium alloy production process are:
[0004] 1. Patent document CN105838952B discloses a magnesium alloy kettle and its manufacturing method. In the manufacturing process of the magnesium alloy kettle, the casting furnace extracts magnesium liquid from the crucible of the melting furnace for casting. Since the melting time is longer than the extraction time, the overall process is time-consuming, the process is complicated, the production cost is increased, and the production efficiency is low.
[0005] 2. Patent document CN116200624A discloses a degassing device for the production of hypereutectic aluminum-silicon alloys. During the production of hypereutectic aluminum-silicon alloys, the movement of the degassing device will leak the polluted gas that has not been completely extracted above the melting chamber into the air, which poses a certain safety hazard. The leakage of polluted gas can easily lead to a harsh environment and thus cause harm to the health of workers.
[0006] 3. Patent document CN108311652B discloses a preparation process for ME20M magnesium alloy flat ingots. During the preparation process of the magnesium alloy flat ingots, the metal liquid level in the preparation equipment cannot be kept highly stable. The contact between the magnesium alloy liquid and air increases the occurrence of oxidation reaction. Due to the instability of the liquid flow, casting defects are easily generated, resulting in slag inclusions. The purity and mechanical properties of the castings cannot be guaranteed. Summary of the Invention
[0007] The purpose of this invention is to provide a magnesium alloy workshop to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a magnesium alloy workshop, comprising a melting chamber, a casting chamber, a weighbridge, a die-casting workshop, and a slag-refining chamber. The melting chamber includes a melting furnace, a melting chamber intelligent crane, an AGV, a crucible, and a dust removal hood. The weighbridge is installed at the center of the bottom wall of the workshop. The die-casting workshop consists of die-casting equipment and a machine-side furnace. The casting chamber consists of a casting machine and a magnesium ingot conveyor belt.
[0009] Preferably, the melting furnace consists of a melting base and a melting furnace insulation layer. The melting furnace insulation layer is installed on top of the melting base.

The dust removal hood is installed inside the melting chamber. A hoist is installed on the top inner side of the dust removal hood, and a stirring paddle is installed at the output end of the hoist.
[0010] Preferably, the AGV consists of an AGV base and a crucible insulation device, with the crucible insulation device installed on top of the AGV base.
[0011] Preferably, the slag refining chamber includes a slag refining machine, a slag dumping and tilting machine, and a slag refining chamber intelligent crane. The slag refining chamber intelligent crane is installed inside the slag refining chamber, and a crucible clamp is installed at the bottom of the slag refining chamber intelligent crane.
[0012] Preferably, the machine-side furnace includes a machine-side furnace crucible, a lifting device, a liquid suction pipe, a power device, and a die-casting liquid supply pipe. The machine-side furnace crucible is installed inside the machine-side furnace. The liquid suction pipe is installed at the top of the lifting device, with one end of the liquid suction pipe located inside the crucible and the other end located inside the machine-side furnace crucible. The power device is installed inside the machine-side furnace crucible and is connected to the output end of the liquid suction pipe via a pipe. The machine-side furnace supplies liquid to the die-casting equipment through the die-casting liquid supply pipe.
[0013] An automated production process for a magnesium alloy workshop, preferably comprising the following steps: 1. Smelting magnesium raw materials; 2. Transferring to the die-casting workshop; 3. Siphoning liquid supply and die-casting; 4. Slag dumping.
[0014] Preferably, the magnesium raw material smelting steps are as follows: when the magnesium is smelted in the melting furnace, the stirring paddle stirs the mixture, the dust collector uses negative pressure to remove polluting gases generated during the melting process, and the dust collector is removed when the magnesium in the melting furnace reaches the required molten state.
[0015] Preferably, the transfer steps in the die-casting workshop are as follows: Crucible hoisting: The intelligent overhead crane in the melting chamber hoists the crucible from the melting furnace to the AGV, and another set of AGVs carries the empty crucible to the position of the previous set of crucibles for replenishment; Weighing and conveying: The crucible insulation device keeps the full magnesium water in the crucible warm, and the AGV enters and exits the die-casting workshop by weighing the magnesium water consumption in the die-casting workshop. The AGV transports the crucible to the furnace suction position at the machine side.
[0016] Preferably, the siphon liquid supply and die casting steps are as follows: Intermittent siphon: The lifting device drives the liquid suction pipe to descend into the crucible. The other end of the liquid suction pipe forms a seal with the liquid inlet of the power device. When the power device is activated, the magnesium liquid in the crucible is sucked into the machine side furnace crucible. After the siphon effect is formed, the power device stops working. When the liquid level in the machine side furnace crucible reaches the required level, the power device reverses to block the drain port. A negative pressure is formed in the liquid suction pipe to maintain the siphon state; Liquid supply and die casting: The machine side furnace supplies liquid to the die casting equipment through the die casting liquid supply pipe so that the die casting equipment performs magnesium alloy die casting. After the liquid level in the machine side furnace crucible gradually decreases, the power device is activated to open the drain port. The magnesium liquid in the AGV crucible continues to be sucked into the machine side furnace crucible.
[0017] Preferably, the slag dumping steps are as follows: Slag treatment: After the magnesium liquid in the crucible is extracted, the AGV transfers the crucible to the slag chamber. The intelligent crane in the slag chamber lifts the crucible to the slag dumping and tilting machine. The slag dumping and tilting machine dumps the remaining waste slag in the crucible into the slag furnace; Furnace replenishment: The intelligent crane in the slag chamber lifts the empty crucible to the AGV. The AGV waits according to the empty status of the melting furnace. The intelligent crane in the melting chamber lifts the empty crucible to the melting furnace. The melting furnace is moved back into the dust removal hood for the next round of feeding and melting.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] This invention utilizes multiple intelligent cranes and AGVs to automatically transfer molten metal in the magnesium alloy workshop, directly transporting crucibles to the casting room or die-casting workshop. It innovatively achieves direct supply of molten magnesium to the die-casting workshop, and the flexible transfer of molten magnesium shortens the process flow in the magnesium alloy production workshop. The entire workshop is functionally divided into a melting chamber, casting chamber, slag refining chamber, and die-casting workshop, optimizing the layout of the magnesium alloy workshop and eliminating the previous inefficient manual connection of various nodes. This achieves safe and green production, creating more output value within the same time and factory area. Direct supply of molten magnesium significantly reduces production costs, improves production efficiency while enhancing die-casting quality, and reduces heat loss during the cooling, preheating, and remelting processes of molten magnesium. Reducing preheating and remelting processes lowers die-casting energy consumption by more than 30%, further reducing carbon emissions.
[0020] This invention replaces the movement of the dust collector hood with the movement of the melting furnace. The traditional dust collector hood movement process will leak the polluted gas that has not been completely extracted from the melting chamber into the air, which poses a certain safety hazard. The movement of the melting furnace can ensure zero leakage of polluted gas. The movement of the melting furnace, together with the dust collector hood, achieves zero leakage of polluted gas during melting and crucible hoisting, reducing the leakage of polluted gas in the melting chamber and the harm to human health caused by the harsh environment. The slag dumping equipment in the slag chamber can ensure that there is no waste slag left in the crucible, reducing slag cleaning time and further improving the production efficiency of magnesium alloy.
[0021] This invention utilizes the siphon effect to absorb and release molten magnesium between the AGV crucible and the machine-side furnace crucible. After the AGV transports the crucible to the machine-side furnace's liquid absorption position, the lifting device lowers the liquid absorption pipe into the crucible. The other end of the liquid absorption pipe forms a seal with the liquid inlet of the power unit. When the power unit is activated, the molten magnesium in the crucible is drawn into the machine-side furnace crucible. After the siphon effect is formed, the power unit stops working, ensuring a stable liquid level in the machine-side furnace crucible. The negative pressure siphon state can effectively reduce the contact between the molten magnesium alloy and air, thereby reducing the occurrence of oxidation reactions. The negative pressure siphon can reduce the impact and turbulence of the liquid flow, reducing casting defects caused by unstable liquid flow. Maintaining a stable liquid level can reduce slag inclusions caused by liquid level fluctuations, further improving the purity and mechanical properties of the castings. Attached Figure Description

For example, "connection" can be a fixed connection or a movable 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; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0031] Example 1, an embodiment of the present invention: a magnesium alloy workshop, including a melting chamber, a casting chamber and a weighbridge 13. The melting chamber includes a melting furnace 1, a melting chamber intelligent crane 2, an AGV 3, a crucible 4 and a dust removal hood 5. The weighbridge 13 is installed at the center of the bottom wall of the workshop. The die casting workshop consists of a die casting equipment 14 and a machine-side furnace 15. The casting chamber consists of a casting machine 11 and a magnesium ingot conveyor belt 12.
[0032] The melting furnace 1 consists of a melting base 1-1 and a melting furnace insulation layer 1-2. The melting furnace insulation layer 1-2 is installed on top of the melting base 1-1. The crucible 4 is installed inside the melting furnace 1. The intelligent trolley 2 of the melting chamber is installed inside the melting chamber and is located above the melting furnace 1. The bottom of the intelligent trolley 2 of the melting chamber is equipped with a crucible clamp 2-1, which cooperates with the crucible 4. The dust hood 5 is installed inside the melting chamber. The top inner side of the dust hood 5 is equipped with a hoist 6. The output end of the hoist 6 is equipped with a stirring paddle 7.
[0033] The AGV3 consists of an AGV base 3-1 and a crucible insulation device 3-2, with the crucible insulation device 3-2 installed on top of the AGV base 3-1.
[0034] The melting base 1-1 can move left and right along the direction of the sectional view of the melting chamber. The melting furnace 1 melts magnesium and other raw materials. The intelligent trolley 2 in the melting chamber and the intelligent trolley 2 in the slag refining chamber are both equipped with crucible clamps 2-1. The intelligent trolley 2 in the melting chamber lifts the crucible 4 from the melting furnace 1 to the AGV3. When the melting furnace 1 is performing melting operations, the stirring paddle 7 stirs it. Polluting gases are generated during the melting process. The dust hood 5 uses negative pressure to extract the polluting gases. The hoist 6 performs the raising and lowering operations of the stirring paddle 7. The AGV3 enters and exits the die casting workshop via the weighbridge 13. The weight difference before and after die casting liquid supply is calculated to achieve precise control of magnesium water consumption in the die casting workshop.
[0035] Multiple intelligent overhead cranes 2 and AGV3 in the melting chamber realize the automatic transfer of molten metal in the magnesium alloy workshop, and directly transport the crucible 4 to the casting chamber or die casting workshop to realize the direct supply of magnesium water to the die casting workshop. The entire workshop is divided into melting chamber, casting chamber, slag refining chamber and die casting workshop according to function. The layout of the magnesium alloy workshop is optimized. The direct supply of magnesium water greatly reduces the production cost and reduces the heat loss in the cooling, preheating and remelting process of magnesium water. The reduction of preheating and remelting processes reduces the energy consumption of die casting by more than 30%. The traditional process flow of magnesium alloy production workshop, namely magnesium alloy melting - ingot casting - polishing - packaging - transportation to die casting workshop - preheating - remelting - supply of magnesium water to die casting machine by machine side furnace - die casting, is directly shortened to magnesium alloy melting - magnesium alloy magnesium water directly delivered to die casting workshop - siphon supply of magnesium water to machine side furnace - die casting. The process flow of magnesium alloy production workshop is shortened.
[0036] Traditional dust removal devices leak unextracted pollutant gas into the air during movement. However, moving the melting furnace 1 ensures zero leakage of pollutant gas. The movement of the melting furnace 1, in conjunction with the dust removal hood 5, achieves zero leakage of pollutant gas during melting and crucible hoisting. The casting chamber consists of a casting machine 11 and a magnesium ingot conveyor belt 12. Molten metal is transported to the casting machine 11 for casting. After casting, the magnesium ingots are discharged via the magnesium ingot conveyor belt 12 for further processing. The casting chamber is used according to actual production needs.
[0037] The AGV3 is equipped with a crucible insulation device 3-2 to ensure the insulation of the molten magnesium inside the crucible 4 during the transfer process. The AGV3 can directly supply molten magnesium to the die-casting workshop. Compared with railcars, the AGV3 is more flexible and easier to operate than the mother-daughter car. It lays a solid foundation for the subsequent direct supply of molten magnesium and the overall automation of production in the alloy workshop. The use of AGV3 for crucible 4 transfer reduces production costs and increases transportation flexibility compared with railcars, realizing the direct flow of molten metal to the casting chamber and die-casting workshop.
[0038] Example 2, an embodiment of the present invention: a magnesium alloy workshop, including a melting chamber, a die casting workshop and a slag refining chamber. The melting chamber includes a melting furnace 1, a melting chamber intelligent crane 2, an AGV 3, a crucible 4 and a dust removal hood 5. The die casting workshop consists of a die casting equipment 14 and a machine-side furnace 15.
[0039] The melting furnace 1 consists of a melting base 1-1 and a melting furnace insulation layer 1-2. The melting furnace insulation layer 1-2 is installed on top of the melting base 1-1. The crucible 4 is installed inside the melting furnace 1. The intelligent trolley 2 of the melting chamber is installed inside the melting chamber and is located above the melting furnace 1. The bottom of the intelligent trolley 2 of the melting chamber is equipped with a crucible clamp 2-1, which cooperates with the crucible 4. The dust hood 5 is installed inside the melting chamber. The top inner side of the dust hood 5 is equipped with a hoist 6. The output end of the hoist 6 is equipped with a stirring paddle 7.
[0040] The slag refining chamber includes a slag refining machine 10, a slag dumping and tilting machine 11, and a slag refining chamber intelligent crane 8. The slag refining chamber intelligent crane 8 is installed inside the slag refining chamber, and a crucible clamp 2-1 is installed at the bottom of the slag refining chamber intelligent crane 8.
[0041] The machine-side furnace 15 includes a machine-side furnace crucible 15-1, a lifting device 15-2, a liquid suction pipe 15-3, a power device 15-4, and a die-casting liquid supply pipe 15-5. The machine-side furnace crucible 15-1 is installed inside the machine-side furnace 15. The liquid suction pipe 15-3 is installed at the top of the lifting device, with one end of the liquid suction pipe 15-3 located inside the crucible 4 and the other end of the liquid suction pipe 15-3 located inside the machine-side furnace crucible 15-1. The power device 15-4 is installed inside the machine-side furnace crucible 15-1 and is connected to the output end of the liquid suction pipe 15-3 through a pipe. The machine-side furnace 15 supplies liquid to the die-casting equipment 14 through the die-casting liquid supply pipe 15-5.
[0042] After the magnesium liquid in crucible 4 is extracted, AGV3 transfers crucible 4 to the slag refining chamber. The intelligent crane 8 in the slag refining chamber lifts crucible 4 to the slag dumping and tilting machine 9. The slag dumping and tilting machine 9 dumps the remaining waste slag in crucible 4 into the slag refining furnace 10. The slag dumping equipment in the slag refining chamber can ensure that there is no waste slag left in the crucible, reduce the slag cleaning time, and further improve the production efficiency of magnesium alloy.
[0043] After AGV3 transports crucible 4 to the liquid suction position of machine-side furnace 15, lifting device 15-2 lowers the suction pipe 15-3 into crucible 4. Lifting device 15-2 adjusts the working height of suction pipe 15-3. The other end of suction pipe 15-3 forms a seal with the liquid inlet of power unit 15-4. Power unit 15-4 starts, and magnesium liquid in crucible 4 is sucked into machine-side furnace crucible 15-1. After a siphon effect is formed, power unit 15-4 stops working. When machine-side furnace crucible 15-1... When the liquid level in the -1 reaches the required level, the power unit 15-4 reverses to block the drain port, and a negative pressure is formed in the suction pipe 15-3 to maintain the siphon state. The machine side furnace 15 draws magnesium water from the crucible 4 into the machine side furnace crucible 15-1 and supplies magnesium water to the die casting equipment 14. During the die casting process, the injection mechanism of the die casting equipment 14 injects magnesium metal liquid into the preheated mold cavity at high speed and high pressure. The metal liquid quickly fills the mold cavity under high pressure and cools and solidifies in the mold to form the casting of the required shape.
[0044] The negative pressure siphon ensures a stable liquid level in the crucible 15-1 of the machine-side furnace. It effectively reduces the contact between the molten magnesium alloy and air, thus minimizing oxidation. Oxidation not only degrades the performance of the magnesium alloy but also forms oxides and other impurities on the melt surface, affecting the quality of the casting. The suction pressure of the negative pressure siphon can be adjusted according to the material and structure of the casting to achieve an ideal filling speed, helping to reduce casting defects such as porosity and shrinkage, and improving the density and surface quality of the casting. Compared to traditional gravity casting, the negative pressure siphon reduces the impact and turbulence of the liquid flow, reducing casting defects caused by unstable flow. It also offers the advantage of taking a large number of samples at once, reducing sampling frequency and time, and improving production efficiency. Samples from negative pressure siphon casting are easy to process and compare, while also saving raw materials, reducing production costs, and maintaining a stable liquid level to reduce inclusions caused by liquid level fluctuations.

The magnesium ingots after casting processing are discharged via the magnesium ingot conveyor belt 12 for the next process.
