The magnesium alloy furnace manufacturer stated that because the ignition point and melting point of magnesium alloy are 550 ℃ and 650 ℃, it is a very active metal among all metals. At high temperatures, it can react with oxygen to produce magnesium oxide, while also reacting with water to produce hydrogen and magnesium oxide, causing an explosion. Therefore, in the process of melting magnesium alloys, it is necessary to effectively prevent metal oxidation or combustion, which is usually achieved in processes with or without flux on the surface of the metal melt.

Therefore, in the process of melting magnesium alloys, it is necessary to effectively prevent metal oxidation or combustion, which is usually achieved in processes with or without flux on the surface of the metal melt. A large number of experimental studies have shown that gases such as C02. S02. SF6 can provide good protection for magnesium and its alloy melts. However, these substances will undergo chemical reactions with magnesium to generate other substances. These substances form impurities in the magnesium soup, and the resulting large amount of impurities will float on the surface of the soup or attach to the side walls of the furnace. Those with higher density will sink to the bottom of the furnace. As these substances accumulate more and thicker, a large amount of these substances will attach to the crucible wall of the furnace. After a period of time, a hard solid material layer will form, causing a decrease in the crucible volume; At the same time, the heat from the external heating device of the crucible cannot be well transmitted to the inside of the crucible, resulting in a decrease in melting speed and inability to meet production needs, thereby reducing the efficiency of die-casting production and seriously affecting the service life and product quality of the crucible.

The purpose of magnesium alloy melting furnace is to overcome the shortcomings of existing technology, provide a magnesium alloy melting furnace that is easy to salvage the slag between the partitions, ensure normal circulation of the molten soup, and reduce the chance of contact with oxygen or water.

What is the structure of a magnesium alloy furnace? Let's take a look below.

The cover plate of the magnesium alloy melting furnace is equipped with feeding ports, discharging ports, and slag tapping ports, which reduces the setting of slag tapping ports on the furnace cover plate, reduces the contact area between the molten soup in the melting furnace and oxygen or water, and thus reduces the probability of magnesium in the molten soup being oxidized into magnesium oxide; There is a space for molten soup to circulate between the upper end of the partition and the furnace cover plate, and sediment is filtered through the partition. A scum partition is installed in the insulation room, and the scum is filtered through the scum partition. There are molten soup through holes on the second partition, and a filter plate is installed on the insulation room side of the second partition. The filter holes of the filter plate correspond to the molten soup through holes on the second partition, and are filtered through the filter plate; The distance between the partition and the crucible end wall on the second partition is greater than the width of the feeding port, and the distance between the scum partition and the partition is greater than the width of the slag tapping port. The slag tapping tool can easily salvage the partition, second partition, scum plate, and filter plate into the crucible through the slag tapping port and feeding port, thereby avoiding the impact of slag accumulation on liquid flow.

The filter plate is installed on the crucible with grooves on both sides, and there are lifting ears at the upper end of the filter plate for easy removal and cleaning of the filter holes.

The legal information filtering holes are located at the lower end of a filter plate, and the upper end of the filter plate is convenient for filtering scum.

The pore size of some filter holes on the filter plate is 30-40mm, which is convenient for molten soup to pass through and not easy to block the filter holes.
