Description

Technical Field

[0001] The invention relates to the technical field of magnesium alloy preparation, in particular to an automatic production process for a magnesium alloy workshop. Background Art

[0002] Magnesium alloy is an alloy based on magnesium with other elements added. It has the characteristics and advantages of low density, high strength, large elastic modulus and good heat dissipation. The main alloying elements of magnesium alloy include aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium. It is widely used in technical fields such as aerospace, automotive industry, electronic and communication equipment and medical equipment. The automatic production workshop of magnesium alloy uses automation equipment, robots, intelligent control systems and other technical means to realize the entire production process of magnesium alloy materials from raw materials to finished products.

[0003] The defects of magnesium alloy production process in the prior art are: 1. Patent document CN105838952B discloses a magnesium alloy kettle and a manufacturing method thereof. During the manufacturing process of the magnesium alloy kettle, a pouring furnace extracts magnesium liquid from a melting furnace crucible for pouring. Since the melting time is longer than the extraction time, the overall process is time-consuming, the process flow is complicated, the production cost is increased, and the production efficiency is low.

[0004] 2. Patent document CN116200624A discloses a degassing device for the production of hypereutectic aluminum-silicon alloy. During the movement of the degassing device in the production of hypereutectic aluminum-silicon alloy, the unextracted polluted gas above the melting chamber will leak into the air, posing certain safety hazards. The leakage of polluted gas can easily lead to a bad environment and cause harm to the workers.

[0005] 3. Patent document CN108311652B discloses a process for preparing ME20M magnesium alloy slabs. During the preparation process of the magnesium alloy slabs, the metal liquid level in the preparation equipment cannot be highly stable. The contact between the magnesium alloy liquid and the air increases the occurrence of oxidation reactions, which is prone to casting defects due to unstable liquid flow and slag inclusion, making it impossible to guarantee the purity and mechanical properties of the casting. Summary of the invention

The power device is installed on the inner side of the machine-side furnace crucible, and the power device is connected to the output end of the pipette through a pipeline. The machine-side furnace supplies liquid to the die-casting equipment through the die-casting liquid supply pipe.

[0012] An automatic production process for a magnesium alloy workshop, preferably, comprises the following steps: 1. smelting magnesium raw materials; 2. transferring to a die-casting workshop; 3. siphoning liquid supply and die-casting; 4. slag dumping.

[0013] Preferably, the magnesium raw material smelting steps are as follows: the stirring paddle stirs the magnesium when the melting furnace is melting the magnesium, the negative pressure of the dust hood extracts the polluted gas generated during the melting process, and the dust hood is removed when the molten state of the magnesium in the melting furnace reaches the requirement.

[0014] Preferably, the steps of transferring to the die-casting workshop are as follows: crucible hoisting: the intelligent crane in the melting chamber hoists the crucible from the melting furnace to the AGV, and another group of AGVs carry empty crucibles to the position of the previous group 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 and controls the magnesium water consumption in the die-casting workshop through the floor scale, and the AGV transports the crucible to the liquid suction position of the machine-side furnace.

[0015] Preferably, the siphon liquid supply and die-casting steps are as follows: intermittent siphoning: the lifting device drives the pipette to descend into the crucible, and the other end of the pipette forms a seal with the liquid inlet of the power unit.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention realizes the automatic transportation of molten metal in the magnesium alloy workshop through multiple intelligent driving vehicles and AGVs, and directly transports the crucible to the casting room or die-casting workshop, creatively realizing the direct supply of magnesium water in the die-casting workshop. The flexible transportation of magnesium liquid shortens the process flow of the magnesium alloy production workshop. The whole workshop is divided into a melting chamber, a casting chamber, a slag refining chamber and a die-casting workshop according to its function, optimizes the layout of the magnesium alloy workshop, and bids farewell to the previous inefficient working method of manually connecting various nodes, realizes safe production and green production, and creates more output value within the same time and the same plant area.

[0018] 2. The present invention changes the movement of the dust hood into the movement of the melting furnace. The traditional movement of the dust hood will cause the unextracted polluted gas above the melting chamber to leak into the air, posing a certain safety hazard. The movement of the melting furnace can achieve zero leakage of polluted gas. The movement of the melting furnace cooperates with the dust hood to achieve zero leakage of polluted gas during melting and crucible lifting, reducing the leakage of polluted gas in the melting chamber and the harm of the harsh environment to the human body. The slag dumping equipment in the slag chamber can ensure that there is no waste slag left in the crucible, reducing the slag cleaning time, and further improving the production efficiency of magnesium alloys.

[0019] 3. The present invention uses the siphon effect to absorb and release magnesium water between the AGV crucible and the machine-side furnace crucible. After the AGV transports the crucible to the machine-side furnace liquid absorption position, the lifting device drives the liquid absorption tube to descend and enter the crucible. The other end of the liquid absorption tube forms a seal with the liquid inlet of the power unit. When the power unit is started, the magnesium liquid in the crucible is sucked into the machine-side furnace crucible. After the siphon effect is formed, the power unit stops working to ensure that the liquid level in the machine-side furnace crucible is stable. The negative pressure siphon state can effectively reduce the contact between the magnesium alloy liquid and the air, thereby reducing the occurrence of oxidation reactions. The negative pressure siphon can reduce the impact and turbulence of the liquid flow, reduce the casting defects caused by unstable liquid flow, and maintain a stable liquid level. The slag inclusion phenomenon caused by liquid level fluctuations can be reduced, and the purity and mechanical properties of the castings can be further improved. BRIEF DESCRIPTION OF THE DRAWINGS

The melting furnace 1 melts magnesium and other raw materials. The melting chamber intelligent crane 2 and the slag chamber intelligent crane 2 are both equipped with a crucible clamp 2-1. The melting chamber intelligent crane 2 hoists the crucible 4 from the melting furnace 1 to the AGV 3. When the melting furnace 1 is performing the melting operation, the stirring paddle 7 stirs it. Polluted gas will be generated during the melting process. The dust hood 5 will use negative pressure to extract the polluted gas. The lifting hoist 6 performs the raising and lowering operations of the stirring paddle 7. The AG, 3 enters and exits the die-casting workshop through the weighing scale 13. The weight difference before and after the die-casting liquid supply is calculated to achieve precise control of the magnesium water consumption in the die-casting workshop.

It lays a solid foundation for the subsequent direct supply of magnesium liquid and the overall production automation of the alloy workshop. Compared with rail vehicles, the use of AGV3 for the transportation of crucible 4 reduces production costs, increases transportation flexibility, and enables the molten metal to directly pass through the pouring room and die-casting workshop.

During the die casting process, the injection mechanism of the die casting equipment 14 is used to inject the 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 is cooled and solidified in the mold to form a casting of the desired shape; The negative pressure siphon state ensures that the liquid level in the crucible 15-1 of the machine-side furnace is stable. The negative pressure siphon state can effectively reduce the contact between the magnesium alloy liquid and the air, thereby reducing the occurrence of oxidation reaction. Oxidation will not only lead to a decrease in the performance of the magnesium alloy, but also form oxides and other impurities on the surface of the melt, 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 obtain an ideal filling speed, which helps to reduce casting defects such as pores, shrinkage, etc., and improve the density and surface quality of the casting. Compared with traditional gravity casting, negative pressure siphon can reduce the impact and turbulence of the liquid flow, and reduce casting defects caused by unstable liquid flow. Negative pressure siphon has the advantage of a large number of one-time sampling, which can reduce the number and time of sampling and improve production efficiency. The negative pressure suction casting sample is easy to process and compare, while saving the use of raw materials, reducing production costs, maintaining a stable liquid level and reducing slag inclusions caused by liquid level fluctuations.
