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.
The development of magnesium alloy continuous ingot casting machine has changed the status quo of low efficiency and high consumption of metal materials and has incomparable technical advantages. Generally speaking, magnesium alloy continuous ingot casting machine has the following technical characteristics:
1, due to the rapid cooling of the metal, its fine crystallization, dense organization, good mechanical properties; Continuous casting, the crystallization process will make the casting structure uniform throughout the length;
2, because there is no gate, can save the amount of metal, improve the yield;
3, simplify the process, remove the modeling process, reduce the intensity of labor; The amount of floor space required is also greatly reduced;
4, continuous casting production is easy to realize mechanization, automation, improve production efficiency.
5, if the continuous casting of high temperature ingot immediately rolling, can eliminate the ingot in the general rolling before the heating process, can greatly save energy, improve efficiency.
Magnesium alloy continuous ingot casting machine feeding pot and related hot parts and imported steel from Germany, using optimized process manufacturing, has good high temperature performance, corrosion resistance, wear resistance, long service life. The furnace is well designed and well manufactured. The hot parts are made of imported steel, resistant to corrosion and high temperature. This series of furnace can be used with all kinds of hot chamber mould-casting machine, which has low energy consumption, high condensation rate, perfect gas protection device and uniform gas mixing.
Low energy consumption, high condensation rate perfect gas protection device, gas mixing uniform, stable flow, full protection, equipped with automatic switching device bimetal composite steel plate manufacturing crucible, no pollution to magnesium liquid, long service life heating element work stable, with long service life multiple thermocouple control furnace and box temperature automatic alarm device: overtemperature alarm, leakage alarm.
The crude magnesium was recovered and produced under the vacuum condition of 1200-1250℃ and 1.33Pa, and finished magnesium ingot was obtained after flux refining, ingot casting and surface treatment. The defects of Pijiang magnesium smelting: the consumption of 1 ton of metal magnesium ingot requires the consumption of 12-14 tons of dolomite; 8-10 tons of anthracite and bituminous coal; 5-6 tons of by-product recycled slag, which has not found a better use in the past, polluting the environment; The labor intensity is high, the dust pollution of the raw material workshop is serious, the nickel content is too low, so the flotation is used to recover, but the impurity magnesium may not be easy to control.

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.
