Magnesium alloy smelters say that magnesium alloys are very active among all metals because they have an ignition point of 550℃ and a melting point of 650℃. At high temperatures, it reacts with oxygen to form magnesium oxide, while it reacts with water to form hydrogen and magnesium oxide, which causes an explosion. Therefore, metal oxidation or combustion must be prevented effectively in the process of melting magnesium alloy, which is usually achieved in the process of flux or no flux on the surface of metal melt. A large number of experimental studies show that gases such as C02.S02.SF6 can play a good protective role on magnesium and its alloy melt, but these substances will react with magnesium to form other substances. Such substances constitute impurities in magnesium soup, and a large number of impurities will float on the surface of the molten soup or adhere to the furnace side wall, and the dense ones will sink to the bottom of the furnace. When the substance becomes thicker and more concentrated, a large amount of this substance adheres to the crucible wall of the furnace. After a period of time, it will form a hard solid layer of material, causing a decrease in the volume of crucible. At the same time, heat from the external heating device of crucible cannot be properly transmitted into crucible, which reduces the melting speed and cannot meet the production requirements, thus reducing the production efficiency of die casting and seriously affecting the service life and product quality of crucible.
The purpose of magnesium alloy melting furnace is to overcome the deficiency of the existing technology, provide a magnesium alloy melting furnace which is easy to catch the slag between the partitions, ensure the normal circulation of the molten soup, and reduce the probability of contact with oxygen or water.
What is the structure of magnesium alloy furnace? Let's find out.
The cover plate of magnesium alloy furnace is provided with a feed port, a discharge port and a slagging port, which reduces the slagging port of the cover plate and the contact area between the molten soup and oxygen or water in the melting furnace, thus reducing the probability that the magnesium in the molten soup is oxidized into magnesium oxide; There is a flow space between the upper end of the partition and the furnace cover plate, the slag is filtered through the partition, the scum partition is arranged in the insulation room, the scum is filtered through the scum partition, the two baffle plate is provided with a molten soup through the hole, the two baffle greenhouse side is provided with a filter plate, the filter hole of the filter plate and the two baffle plate of molten soup through the hole, through the filter plate; The distance between the partition plate and the crucible end wall on the second partition plate is greater than the width of the feed port, and the distance between the scum partition plate and the scum crucible is greater than the width of the slagging port. The slagging tool can easily lift the partition plate, the second partition plate, the scum plate, and the filter plate into the crucible through the slagging port and the feed port, thus avoiding the influence of slag accumulation on the liquid flow.
The two sides of the filter plate are arranged on the crucible with grooves, and the upper end of the filter plate is provided with lifting lug, which is convenient to remove the filter plate and clean the filter hole of the filter plate.
The information filter hole is located at the lower end of a filter plate, and the upper end of the filter plate is convenient for filtering scum.
The aperture of some filter holes on the filter plate is 30-40mm, which is easy to melt the soup through, and not easy to plug the filter hole.

The core of magnesium alloy continuous ingot casting machine is continuous casting technology
The core of magnesium alloy continuous ingot casting machine is continuous casting technology. Continuous casting is a casting method in which liquid metal is continuously injected into one end of the die and molding materials are continuously pulled out from the other end. When the casting is drawn from the metal form to a certain length, the casting can be cut off while pouring; It is also possible to stop pouring when the casting reaches a certain length in order to obtain a certain length of casting. Magnesium alloy continuous ingot casting machine can be used for casting various high density plate, round bar, hollow pipe and other profiles.

Function and application of magnesium alloy furnace
In magnesium alloy smelting process, metal oxidation reaction should be avoided to prevent metal combustion. To achieve this effect, we usually sprinkle some flux on the metal melt. Sometimes, we can also use fluxless processes. The common flux is beryllium metal, and the common flux free process is flux free melting. The melting process of magnesium alloy is mainly flux melting. The flux removes impurities from the magnesium and forms a protective film on the surface of the magnesium alloy melt to isolate air. However, the effect of flux film on air isolation is not very ideal, and the magnesium loss caused by oxidation combustion in smelting process is relatively large.
