Description
Technical Field
The invention relates to the technical field of pure magnesium and magnesium alloy casting and conveying, in particular to an environment-friendly pure magnesium and magnesium alloy casting and conveying machine.
Background
Magnesium metal is a novel light corrosion-resistant non-ferrous metal material developed in the twentieth century, the development of magnesium was dependent on military industry before the 50 s, and the application of magnesium after the 60 s is mainly concentrated in four fields of magnesium alloy production, aluminum alloy production, steel making and desulfurization, aviation military industry, and is widely applied to automobile manufacturing industry, light industry, metallurgical industry, chemical industry, electronic industry, instrument manufacturing industry and the like. For the convenience of modern industrial application, most of pure magnesium and magnesium alloy raw material forms exist in the form of magnesium ingots, and section or standard part blanks are obtained through processes of remelting ingots, reshaping and the like. Because pure magnesium ingots and magnesium alloy ingots are very easy to oxidize and burn in a high-temperature pouring environment, the oxidation rate and the burn-out rate not only directly influence the quality of products, but also greatly affect the production of downstream finished products.
Pure magnesium and magnesium alloy can effectively remove impurities through refining, but the ignition point (metal magnesium starts to burn at 632-635 ℃) is lower than the melting point (650 ℃), so that oxidation and burning loss cannot be avoided if no oxygen insulation and protection measures are taken during liquid casting, and the prior art has the following casting protection related technologies:
sulfur powder is used in the casting process, when sulfur is contacted with magnesium, on one hand, the sulfur is heated and evaporated (the boiling point of sulfur is 446 ℃) to form SO2 protective gas, on the other hand, the sulfur reacts with the magnesium alloy melt, a dense MgS film (the density coefficient a is 0.95) is formed on the surface of the magnesium alloy melt, and the oxidation of the magnesium alloy melt is slowed down. However, the sulfur powder and SO2 not only pollute the environment, but also have serious destructive effects on human respiratory tract, intestinal tract, mucosa, skin and the like, and the practical production shows that the use of the sulfur powder can slow down oxidation and combustion, but the effect is not ideal due to factors such as uneven attachment surface, untimely spraying and the like.
The gas protection is used for preventing combustion, and inert gases or mixed gases such as CO2, SF6, R-134a and the like are used for forming a protective film to achieve the purposes of preventing oxidation and retarding flame, but the gas supply or gas distribution process is too dispersed, and although the open gas distribution has a protective effect, on one hand, the gas is not quantitative and the utilization rate is not high, and on the other hand, the gas is discharged into the atmosphere to cause pollution and greenhouse effect.
With the need of high efficiency and efficiency, when the gas is protected, the upper part of the original open gas distribution pipe is sealed to form a semi-open type protective gas cover, so that the protection effect is further improved, but protective gas is removed or not returned, and finally the protective gas is discharged into the atmosphere to cause pollution.
