What is the structure of magnesium alloy continuous ingot casting machine?
Magnesium alloy continuous ingot casting machine manufacturers said that, at present, lead ingot casting equipment has been widely used in domestic lead smelters, the main operation has achieved varying degrees of mechanization or automation, casting, the use of lead pump molten lead pot liquid lead pump into the casting bag, liquid lead through the casting bag quantitative pouring device injected into the ingot mold for casting, scraper liquid lead ingot surface slag layer, Then, after cooling forming, printing and demudding process, the demudding lead ingot is stacked by cantilever hanging. It plays an active role in improving the working conditions and reducing the labor intensity of finished lead ingot.
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.

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.

What are the advantages of magnesium alloy smelters? Let's find out.
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.
