[0002] During the process of die-casting and melting aluminum, an aluminum ladle, a degasser, and a melting furnace are required. The aluminum ladle (also known as an aluminum transfer ladle) is an important device for transferring molten aluminum during the production process. It can safely and efficiently transfer molten aluminum from one place to another. Its main function is to safely transfer high-temperature molten aluminum, avoid leakage or splashing during the transfer process, and ensure production safety.

[0003] A degasser is a device specifically used for purifying metal melts such as molten aluminum. Its core function is to remove harmful substances such as hydrogen and impurities in the metal liquid through specific methods to improve the quality of the metal.

[0004] A melting furnace is an important industrial device, mainly used for melting metal ingots and some waste metals, adding necessary alloy components, and melting them into the required alloy through operations such as slag skimming and refining.

[0018] The following is a further detailed description through specific embodiments:

[0019] 1. The reference numerals in the drawings of the specification include: smelting furnace 1, feed inlet 101, water discharge chute 102, degasser 2, ladle dryer 3, heat insulation cover 301 of the ladle dryer, base 302, column 303, lifting chain 304, elevating mechanism 305, ladle 4, operation platform 5, operation surface 501, track 6, rail car 7, motor reducer 8.

[0020] Embodiment 1

[0021] As Figure 1 and 2As shown in the figure, a transfer line for a die-casting melting station includes a melting furnace 1, a degassing machine 2, a ladle dryer 3, a ladle 4, an operating platform 5 and a track 6. The ladle 4 travels on the track 6 through a rail vehicle 7. The ladle dryer 3, the operating platform 5, the melting furnace 1 and the degassing machine 2 are arranged in sequence along the direction of the track 6.

[0022] The operating surface 501 of the operating platform 5 is higher than the feeding port 101 of the melting furnace 1.

[0023] The ladle dryer 3, the operating platform 5, the melting furnace 1 and the degassing machine 2 are located on the same side of the track 6.

[0024] The water discharge chute 102 of the melting furnace 1 is higher than the water inlet of the ladle 4.

[0025] The ladle dryer 3 is provided with a ladle heat insulation cover 301 for covering the ladle 4.

[0026] The ladle dryer 3 is provided with a base 302, columns 303 and lifting chains 304. The base 302 supports the columns 303 on both sides. There is a lifting mechanism 305 between the columns 303 on both sides. The lifting mechanism 305 is connected to the two lifting chains 304. The two lifting chains 304 are connected to the ladle heat insulation cover 301 below the lifting mechanism 305.

[0027] The rail vehicle 7 is provided with a motor reducer 8.

[0028] Among them, how the melting furnace 1 melts, how the degassing machine 2 intakes air for degassing, how the ladle dryer 3 bakes the ladle, and the ladle 4 are all functions that can be directly realized by existing products, so there is no need to elaborate here. The melting furnace 1, the degassing machine 2, the ladle dryer 3 and the ladle 4 with corresponding functions can be directly purchased.

[0029] The melting furnace mainly consists of a power supply, electrodes (cathode and anode), gas nozzles, crucibles and other parts. In the energized state, a high temperature is generated between the two electrodes through the current and maintained for a certain time, so as to heat the metal material to its melting point or boiling point; the working principle of the melting furnace involves the comprehensive action of electric energy, heat energy and chemical reactions. When the DC voltage enters the inverter circuit through the rectifier filter, it is boosted to alternating current by the transformer and supplied to the thyristor module, controlling the conduction angle and closing time of the thyristor element, so as to change the output pulse width and realize the control of the load power. In the energized state, a plasma region or ionized region is formed between the anode and cathode. Due to the increase in electron density, the volume of the gas expands sharply, generating a large amount of heat energy, so that the metal material reaches the required melting point or boiling point.

[0030] The basic principle of the degasser is to use inert gases (such as argon, nitrogen, etc., with a purity of over 99.99%) to carry out physical or chemical reactions with hydrogen and impurities in the molten metal, so as to separate them from the molten metal. Specifically, the rotary degasser uses a rotor that rotates at high speed and injects inert gas, breaking up the large inert gas bubbles into very fine small bubbles and evenly dispersing them in the molten metal. The total surface area of these tiny bubbles increases sharply, thus increasing the contact opportunity with hydrogen and impurities in the molten metal, and then bringing these harmful substances to the liquid surface for removal.

[0031] The working principle of the ladle dryer is to pass the high-temperature gas flow generated by the combustion of gas through a heat exchanger, so that the wet material (here it is the metal ladle) is dried in the high-temperature gas flow. This equipment mainly consists of a gas burner, a heat exchanger and a fan. The gas burner mixes gas with air and then ignites it to produce high-temperature combustion gas. The combustion gas passes through the heat exchanger, releases heat while contacting the wet material, and evaporates the moisture in the material. The fan conducts the hot gas flow to the material by inhaling and discharging air to achieve rapid drying.

[0032] The above are only the embodiments of the present utility model. Common knowledge such as the specific structures and characteristics known in the art are not described in detail here. Those of ordinary skill in the art know all the common general technical knowledge in the technical field to which the utility model pertains before the application date or the priority date, can know all the existing technologies in this field, and have the ability to apply the conventional experimental means before this date. Those of ordinary skill in the art can, under the inspiration given in this application, combine their own abilities to improve and implement this solution. Some typical known structures or known methods should not become an obstacle for those of ordinary skill in the art to implement this application. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
