Description
Technical Field
The invention belongs to the field of metals, and particularly relates to a device for detecting magnesium metal evaporation.
Background
Magnesium has wide application prospects in the fields of structural materials, metallurgical reduction and the like due to low density, high specific strength and strong reducibility, but the use performance of magnesium is often affected by the content of impurities. Iron and nickel in magnesium, for example, can increase the corrosion rate of magnesium alloys; in addition, when magnesium is used as a reducing agent, the impurities are also introduced into the product, so that the quality of the product is reduced. Therefore, in order to improve the usability of magnesium, the market demand for high purity magnesium is urgent.
By analyzing the physical properties of magnesium and impurities (iron, manganese, silicon, aluminum, etc.) in magnesium, it is known that the saturated vapor pressure of magnesium is significantly higher than that of these impurities, and thus separating magnesium from impurities by distillation of magnesium is an important means for the production of high purity magnesium.
As the evaporation rate formula of the metal shows, the lower the vacuum degree and the higher the temperature, the faster the evaporation rate of the metal. In order to improve the production efficiency, the evaporation process of magnesium is generally performed under high temperature and vacuum environment. In view of the production costs, the effective heating time must be reasonably controlled according to the evaporation process of magnesium. The current industry judgment on the magnesium evaporation process is generally based on experience, and the evaporation time of magnesium ingots is often not accurately estimated due to the influence of a temperature control device of a furnace and the geometric structure in the furnace, so that the heating time needs to have enough margin to cover the whole evaporation process, and the excessive heating time seriously causes low production efficiency and waste of energy, so that the industry needs a device capable of timely detecting whether the magnesium metal is evaporated.
At present, in a high-temperature vacuum environment, particularly in a reducing atmosphere of magnesium vapor, besides ensuring the purity of the magnesium vapor, how to judge the beginning and the end of the evaporation process is always a difficult problem. Because high temperatures and vacuum conditions often result in conventional flowmeters not operating effectively, and magnesium vapor as a strong reducing atmosphere can also cause damage to the flowmeter structure.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides a device for detecting magnesium metal evaporation. The device can monitor the temperature change in the reaction chamber in real time, and accurately judge whether the magnesium metal is completely evaporated based on the temperature change, so that the damage to the traditional flowmeter is avoided.
The invention provides a device for detecting magnesium metal evaporation, which is characterized by comprising a reaction bin, a hollow connecting pipe, a sealing assembly and a temperature monitoring device; a reaction chamber is arranged in the reaction chamber, the wall of the reaction chamber is communicated with the reaction chamber and provided with perforations, reactant elemental silicon is arranged in the reaction chamber, and the reaction chamber is connected with one side of the hollow connecting pipe in a conducting way; the other side of the hollow connecting pipe is connected with the sealing component; the temperature monitoring end of the temperature monitoring device sequentially penetrates through the sealing assembly and the hollow connecting pipe and is inserted into the reaction chamber and used for monitoring the internal temperature of the reaction chamber during reaction.
The device is used for detecting whether the crude magnesium is completely evaporated during the evaporation and purification of the magnesium, and the detection principle is as follows:
The magnesium vapor and the silicon particles can react under certain conditions, and Mg 2 Si is formed on the surfaces of the silicon particles, and the reaction formula is as follows: mg (g) +si(s) =mg 2 Si(s), and the reaction is exothermic; in addition, mg 2 Si can undergo endothermic decomposition reaction at a certain temperature, and is decomposed into magnesium vapor and silicon, and the reaction formula is: mg 2 Si(s) =mg (g) +si(s), the reaction being endothermic.
The device for detecting the evaporation of magnesium metal needs to be matched with a device capable of providing a gaseous magnesium source. The description will now be made of a metal melter-gasifier as a means for providing a gaseous "magnesium source":
Firstly, the device is embedded and inserted into the top position of the gas outlet hole of the metal melting gasification furnace, and when coarse magnesium is in the initial stage of evaporation in the metal melting gasification furnace, a large amount of magnesium vapor rises and sequentially passes through the top position of the gas outlet hole and the perforation of the bin wall and enters the reaction chamber.
Secondly, magnesium vapor reacts with simple substance silicon particles in a reaction chamber to generate Mg 2 Si, and after the coarse magnesium is evaporated, because no magnesium vapor enters the reaction chamber, the concentration of the magnesium vapor in the reaction chamber is greatly reduced, so that Mg 2 Si is reversely decomposed and re-decomposed into magnesium vapor and simple substance silicon, the reaction is endothermic, the temperature in the reaction chamber is reduced, the temperature change is collected and fed back by a temperature monitoring device in the reaction chamber, and the inflection point of the temperature reduction can judge that the coarse magnesium is evaporated.
The inventor repeatedly tests that the reaction time is zero when magnesium vapor enters the reaction chamber, the temperature and time relation of the reaction chamber (shown in figure 5) is monitored and recorded in real time through the temperature monitoring device, and the temperature inflection point is analyzed by the map, so that the temperature inflection point is used for judging that the crude magnesium is evaporated. The 3 curves of fig. 5 represent the results of 3 experiments, respectively.

Further, the mesh aperture of the inner layer mesh plate and the mesh aperture of the inner layer mesh plate bottom plate are 100-120 meshes.

Further, the outer pressing mechanism is radially provided with an opening groove, and can be installed on the hollow connecting pipe in a clamping mode through the opening groove. In addition, the internal compression mechanism and the external compression mechanism are consistent in structural shape, and the size of the internal compression mechanism and the external compression mechanism can be scaled according to the requirement.

The beneficial effects of the invention are as follows:
The device provided by the invention can monitor the temperature in the reaction chamber in real time, and acquire a signal of complete evaporation of magnesium metal through temperature difference generated by positive reaction (exothermic) and reverse reaction (endothermic) of magnesium vapor and elemental silicon, so as to accurately judge whether the magnesium metal is completely evaporated. The practical problems of low production efficiency and energy waste caused by excessive heating time in production are avoided.
