The bottom portion of the hull of the present invention in which the housing 40 is inserted is shown in perspective.

The present application is made of a light alloy body metal material as described above is very lightweight compared to the conventional boat, but the conventional boat is made of steel or FRP material compared to the hull 20 of the present invention is very heavy and shows a 10 times weight difference In addition, the manufacturing process is difficult, takes a long time, and asbestos, harmful chemicals, thinners and hardeners in the manufacturing process can have a significant adverse effect on the manufacturer, the surrounding environment and the human body.

2 is a perspective view showing the overall structure of the present application as a perspective view according to an embodiment of a light boat having a plurality of keel of the present invention and the hull 20 of the present application is a light alloy or metal material as described above In principle, it is made of any one of light metals including magnesium, beryllium, aluminum, and titanium, and the strength and weight of the metal is guaranteed. It can be used suitably as a material.

The manufacturing method of the above-mentioned lightweight alloy is industrially produced by most of the crawl method

First, titanium is briefly described, and titanium is widely distributed, making up 0.44% of the earth's crust, and titanium metal is found in virtually all forms of rock, sand, clay and other soils.

Also found in plants, animals, natural waters, deep seas, meteorites, and stars, commercially important minerals are titanium iron and rutile, and New Zealand-born American metallurgist Matthew A. Hunter found that TiCl in sealed steel barrels 4) was reduced to sodium to separate pure titanium. Since 1947, titanium has become an important building metal commercially produced by the crawl method (reducing tetrachloride to magnesium).

Pure titanium is ductile, half the weight of iron, twice as heavy as aluminum and polished very well, very low in thermal and electrical conductivity and paramagnetic.

It consists of two crystal structures, but hexagonal dense structure (alpha) is below 882 degreeC, and has a body cubic structure (beta) above 882 degreeC. Natural titanium is composed of five stable isotopes (46 Ti to 50 Ti).

Titanium is important because it forms a useful alloy with most metals and some nonmetals. Some of these alloys have a much higher tension than titanium itself, and titanium has excellent corrosion resistance due to the formation of insoluble oxide film on the surface in various environments. It is a metal with excellent corrosion resistance, so it is used as part of aircraft, spacecraft, missiles and ships. It is also used as an artificial organ because it does not react with body tissues and bones.

Titanium is used as a deoxidizer in steel, and as an alloying additive for reducing the particle size of various steels, lowering the carbon content of stainless steel, controlling the particle size of aluminum and increasing the hardness of copper. Titanium does not discolor at room temperature but reacts with oxygen in the air at high temperatures.

The raw material is usually rutile containing 94% of titanium oxide TiO 2, or titanium iron which contains 60% of titanium oxide, which is once smelted into titanium slag powder, sintered by adding charcoal or coke, and then chlorinated. Titanium tetrachloride is made at around 900 ℃ in a furnace.

TiO 2 + 2C + 2Cl 2 → TiCl 4 + 2CO The produced titanium tetrachloride contains chlorides such as iron, silicon, and vanadium as impurities, and the purified titanium tetrachloride is purified by distillation, and magnesium molten in an argon gas of 1 atm. It is dripped at and isolate | separated into metal titanium.

TiCl 4 + 2Mg → Ti + 2MgCl 2 The reaction is heated again to evaporate the impurities to form a titanium sponge. Usually, 1t of titanium is produced in 1 step and the purity is 99.6 ~ 99.85%.

The iodine method is used to refine this again.

 Crude titanium metal is reacted with iodine at 250 to 300 ° C. to make titanium iodide, and the steam is pyrolyzed at 1,100 to 1,500 ° C. to separate it into high purity titanium and iodine.

Pyrolysis is usually carried out on tungsten wire through electric current, and the titanium obtained by this method is 99.96% because of its high purity. In addition, molten salt electrolysis or the like may be used.

Next is beryllium, which is an alkaline earth metal belonging to group 2 of the periodic table. In 1798, French chemist LN Bocquelin, following the recommendation of mineralogy Ayuy, analyzed emeralds and green tincture and found that they had the same composition. I found it.

 And when the salt of this new element was sweet, it was named Glucinium after the Greek word glucus, which means sweet. However, because it was found that yttrium oxide and other elements of the compound were sweet, the name Beryllium advocated by Kraprot was adopted. This name is derived from beryllos, which is the Greek of the green tint. On the other hand, single metal elements were independently deposited by F. Müller in Germany in 1828 and A.A.B. Busier in France in 3182 by reaction of beryllium chloride and potassium potassium.

In nature, it is widely present as green tint, gold green, and phenasum, but the most important mineral is green tin and contains 11 to 13% of beryllium oxide. Industrially, tin oxide is acid or alkali treated to form an oxide, which is then converted into a fluoride, which is then reduced to metal magnesium, or chloride is melted to precipitate a metal by electrolytic salt electrolysis.

In addition, it is a silver white metal, the surface of which is oxidized in air, turns into grayish white due to the formation of a film, and is soft at room temperature, but is malleable and ductile at high temperature. Toughness, electrical conductivity, elasticity and chemical properties are similar to magnesium, but also similar to aluminum.

It is not eroded by water. Hydrogen, sulfuric acid, etc., generate hydrogen and dissolve well, but they do not dissolve well in nitric acid. Hydrogen also generates hydrogen and melts.

In addition, since neutron trapping is extremely small and a large cross-sectional area is important, it is important as a neutron moderator and a reflector in a nuclear reactor. Moreover, since it is excellent in X-ray transmittance, it is used as the window of an X-ray tube, and it is also used by alloys, such as a beryllium bronze and a beryllium nickel.

The following are the metal elements belonging to the alkaline earth metals of group 2 in the magnesium periodic table, which are the lightest structural metals. Became known through. The silver white metal element itself is not calculated. In 1808, Humphrey Davie first separated mercury by evaporating mercury from a magnesium amalgam obtained by electrolyzing a mixture of magnesia and mercury oxide.

It is the eighth most abundant element (about 2.5%) in the earth's crust, and is distributed in magnesite, dolomite, calcite, serpentine, chrysolite, algae, talc and most asbestos. Sea water contains about 0.13% of magnesium, and most of it is in dissolved chloride, which gives it a unique bitter taste. It is present in about 1/6 of the amount of potassium in human cells and acts as a catalyst for enzymatic reactions in carbohydrate metabolism.

Commercially obtained molten magnesium chloride (MgCl 2), mainly obtained from seawater, is obtained either by electrolysis or by directly reducing the magnesium compound with a reducing agent.

Magnesium fine powder burns with strong white light in the air, so in the past it was mainly used in photographic flash ribbons, gunpowder, peat and fireworks. It is widely used in the aerospace industry because its density is as low as 2/3 of that of aluminum. If the parts made of iron are made of magnesium, the weight of 4.7kg is only 1kg. Pure metals have low structural strengths, making alloys with aluminum, zinc, and manganese to increase hardness, tensile strength, corrosion resistance to salt water, and facilitate casting, welding, and machining. Magnesium alloys have many applications. Used in airplanes, spaceships, machinery, automobiles and portable tools and home appliances, it is produced from a mixture of three isotopes in nature: 24Mg (78.70%), 26Mg (11.17%) and 25Mg (10.13%). A very strong reducing agent that reacts with most acids or boiling water to produce hydrogen but is strong against most alkalis. The oxidation number is always +2 because it loses or shares two electrons in the 3s orbit.

Next is aluminum, a lightweight silver-white metal belonging to the Boron group of the Periodic Table 13, the most abundant metal element in the earth's crust, the most widely used nonferrous metal. Because of its high chemical reactivity, nature does not produce metals by itself, but aluminum compounds are present in almost all rocks and flora and fauna. It is intensively distributed within 16 km of the earth's surface, accounting for about 8% of the earth's crust, and is the second most abundant element after oxygen and silicon.

Aluminum is mainly produced from igneous rocks such as feldspar, feldspar, and mica, and is produced from aluminum silicate, and is produced from hydrated aluminum oxide, which is produced from later weathered bauxite and iron with a higher content of iron than clay and clay. The mixture, bauxite, is the main aluminum ore, and the crystalline aluminum oxide (gold steel and corundum) produced by some igneous rocks is mined with natural abrasives, rubies and sapphires.

It also exists in gemstones such as topaz, garnet and chrysoberyl. Among many other aluminum minerals, alumite and cryolite are of commercial importance.

Aluminum was separated in 1825 by Hans Christian Oersdade using potassium amalgam to reduce aluminum chloride, and in 1809 Sir Humphrey Davy melted

Alumina was electrolyzed to form an iron-aluminum alloy, which was named aluminum. This word was later changed to 'aluminum' in the United Kingdom and other European regions. The German chemist Friedrich Müller made aluminum powder using potassium metal as a reducing agent in 1827, and in 1845 made a small spherical metal to investigate the properties of aluminum.

The new metal was unveiled at the Paris Exposition in 1855, when aluminum was made by reducing molten chloride to sodium, which was expensive, and in 1886, when electricity was relatively rich and cheap, Charles Martin Hall of the United States and Paul of France Louis Toussain eru developed a modern method of producing aluminum commercially at about the same time, namely, by dissolving purified alumina (Al 2 O 3) in molten cryolite (Na 3 AlF 6) and electrolytically producing it in the 1960s. More nonferrous metals were produced than copper.

Adding a small amount of aluminum to a specific metal improves the properties of the metal and can be used for special purposes, such as alloys containing aluminum bronze and magnesium, and adding an appropriate amount of other metals and silicon to aluminum creates an alloy containing aluminum as the main component. Aluminum metals and alloys are widely used in aircraft drying, building materials, durable consumer goods (refrigerators, air conditioners, cookware), electrical conductors, chemical processing equipment and food processing equipment.

Pure aluminum (99.996%) is very soft and weak, while commercial aluminum (pure 99.0 to 99.6%) containing small amounts of silicon and iron is hard, high strength, ductile and malleable, stretched into wires or stretched to thin films. You can make Aluminum is light because it is about 1/3 of the density of iron or copper. In addition, when the metal having high chemical reactivity is left in the air, a hard and strong oxide film is formed on the surface of the metal, so that the corrosion resistance is also high.

Aluminum has excellent thermal and electrical conductivity, so that the thermal conductivity is about 1/2 of copper and about 2/3. The stable isotope of all aluminum that has a surface deep cubic crystal structure and is produced in nature is aluminum-27 (27Al). Metallic aluminum and its oxides and hydroxides are not toxic.

Aluminum slowly dissolves in most dilute acids and quickly dissolves in concentrated hydrochloric acid but does not dissolve well in concentrated nitric acid so it can be transported in aluminum tanks with concentrated nitric acid.

Highly pure aluminum reacts violently with alkalis such as sodium hydroxide and potassium hydroxide to generate aluminum acid ions and hydrogen gas, and finely divided aluminum has affinity for oxygen, so it burns when carbon monoxide or carbon dioxide is present, and aluminum oxide and aluminum carbide However, it does not react with sulfur even at the temperature of red.

The aluminum alloy has a specific gravity of only 35% of iron and has excellent mechanical properties, and thus has been widely used as a light weight structural material of a transport machine including an aircraft. In particular, the recycling rate of materials is more than 90%, contributing to environmental cleanup.

   In addition, the magnesium alloy has been developed over 30 kinds of magnesium alloy, the process is simplified and the side effect of reducing the amount of chips generated during processing from 22% to 10% was obtained.
