An exemplary embodiment of the present invention relates to a heat reduction apparatus for smelting magnesium metal using a heat reduction method, and more particularly, a high temperature magnesium vapor generated by a heat reduction reaction is a low temperature condensation tube Magnesium production apparatus for causing condensation on the wall.

In general, alloy materials containing magnesium have excellent machinability and high vibration damping ability, excellent absorbency against vibration and shock, light weight, and good electromagnetic shielding properties. For this reason, the use of magnesium in parts such as computers, cameras, mobile phones, and the like is expanding recently.

In general, the method for producing magnesium (Mg) is largely represented by heat reduction method and electrolytic smelting method.

Among them, the magnesium production apparatus used in the magnesium heat reduction smelting technology represented by the Pigeon method is shown in FIG. This magnesium manufacturing technology, developed in the 1940s, has been the most representative magnesium smelting technology for nearly 70 years. Currently, about 80% of the world's primary magnesium production is produced by the Pidgeon method, a kind of thermal reduction method.

1 is a view schematically showing the configuration of a magnesium manufacturing apparatus according to the prior art.

Referring to Figure 1, the magnesium manufacturing apparatus 200 according to the prior art is filled with magnesium briquette (B) inside the reaction tube 110 and the reaction of the magnesium oxide reduction is installed on the outside of the reaction tube 110 And a heating furnace 120 for heating the reaction tube 110 and a condensation tube 130 for condensing the magnesium vapor generated in the reaction tube 110 into magnesium in a solid state.

Accordingly, the reaction tube 110 receives heat from the outside by the heating furnace 120 to heat the magnesium briquette B therein to the reaction temperature.

The reaction tube 110 is installed in a horizontal direction from the inside of the heating furnace 120. The heating furnace 120 surrounds the reaction tube 110 and heats the outer circumferential surface of the reaction tube 110. The condensation tube 130 is provided at one side inside the reaction tube 110.

On the other hand, the magnesium manufacturing apparatus 200 according to the prior art is provided with a vacuum composition unit 118, such as a vacuum pump for forming the inside of the reaction tube 110 in a vacuum atmosphere, corresponding to the condensation tube 130 One side of the 110 is provided with a cooling jacket 140.

Therefore, in the related art, when magnesium briquette B is charged into the reaction tube 110, the reaction is performed in a state in which the inside of the reaction tube 110 is formed in a vacuum atmosphere (about 1 torr or less) through the vacuum composition unit 118. About 1200 ° C. of heat is supplied to the reaction tube 110 through the heating furnace 120 outside the tube 110.

Then, the magnesium oxide in the reaction tube 110 causes a reduction reaction at a high temperature and low vacuum to generate magnesium vapor.

Magnesium vapor generated in this way is condensed in the condensation tube 130, by supplying a cooling medium to the cooling jacket 140 corresponding to the condensation tube 130 to condense the magnesium vapor by condensing the magnesium vapor inside the condensation tube 130 Precipitates into a magnesium crown (C) in a solid state, and when a series of processes is completed, the reaction tube 110 is opened to extract the condensed magnesium crown (C).

Meanwhile, in the magnesium manufacturing apparatus 200 according to the prior art, the condensation tube 130 has a round cylindrical shape as shown in FIG. 2, and magnesium vapor is deposited from the inner wall surface of the condensation tube 130 by thermophoresis.

In addition, in order to improve productivity in smelting magnesium, the reaction tube 110 is gradually enlarged, and the condensation tube 130 for condensing magnesium vapor is also required to be enlarged.

As a result, the size of the magnesium crown (C) condensed from the surface of the condensation tube 130 is also very large compared to the existing equipment is required for a separate cutting process to dissolve and refine.

For example, if the heat reduction process produces 30 kg of magnesium in a 300 A reaction tube, but condenses 60 kg of magnesium in a 600 A large reaction tube, the size of the condensed magnesium crown is also close to 600 A. Refining requires a separate cutting process.

In particular, the condensed thickness of the magnesium crown is also important for easy separation of the magnesium crown from the condensation tube.
