The present invention relates to a supersonic launcher, and more particularly, to remove foreign substances or corrosion of a steel structure by using a portable launcher formed to inject powder at a supersonic speed by using the explosive force according to the ignition of the fuel and the plated steel structure It relates to a supersonic launcher for coating on the surface of the coating.

In general, the rust prevention of steel structures has been used by applying a rust preventive paint after a sand blasting process to remove foreign matter or corrosion.

This sand blasting is a method for removing fine scratches, unnecessary paint, oil, rust, etc. formed on the surface of the product by using silica sand or other fine and hard particles.

Sandblasting completely removes the oil from the surface and rubs off the fine sand so that the paint adsorbs well, creating an optimal surface for painting. Sandblasting may be the first step in the application of other finishes, but it may also be the finish of the finished product. Sandblasting involves enormous dust and dirt and can only be operated in a physically isolated environment. Sandblasted surfaces also require extreme care before finishing with the next process. Since the treated surface is very sensitive and oxidizes as soon as it is touched, it has been common to apply an antirust coating to finish.

However, the sand blasting process is not only low in efficiency due to the high noise and low injection speed of the abrasive due to the use of compressed air, but also the short-use paint is removed over time to reduce the rust prevention effect. After a certain period of time to paint again, there was a problem that not only environmental damage, but also consume a huge budget.

In recent years, a thermal spraying method has been widely used in which a metal material to be plated is thermally melted and sprayed onto a steel structure to perform plating.

Such thermal spraying is a technique in which a powder or a linear material is changed into a molten liquid from a high temperature heat source to impinge on a substrate at a high speed to form a rapidly-cooled and laminated film. For heating and melting of materials, heat sources such as high-density combustion flames, arcs and plasmas are required. Thermal spraying is a technique of forming a film on the surface of a base material of different properties, which makes use of the characteristics possessed by the base material to compensate for defects, and is one of the surface treatment methods that enables diversification and enhancement of material functions. The thermal spraying method enables the formation of a thick film at a high speed, and it is possible to use materials such as metals, ceramics, glass and plastics. And the surface layer which cannot be obtained using another method can be made from using the kind of material and the original characteristic of a thermal spraying process well. In order to upgrade the product quality and extend the service life, it is necessary to understand the thermal spraying method, the device configuration, the characteristics and development of the thermal spraying process, the materials used and the properties of the film.

Currently, the spraying method used can be roughly classified into gas type using energy by reaction of oxygen and combustible gas and electric type using electric energy depending on the type of heat source for heating the spraying material.

Such gas spraying typically includes flame spraying, explosion spraying and ultra-fast spraying, and electric spraying includes arc spraying, plasma spraying, linewidth spraying and laser spraying.

Flame Spraying (FS) is the ratio of oxygen and fuel gas (acetylene) 1: 1 to 1: 1.1, the flame temperature is about 3000 ~ 3350 ° Ｋ, the flame speed is about 80 ~ 100 m / s to be. The thermal spraying material can be supplied in the form of wire or rod, not powder. Depending on the material used, it can be divided into molten iron, molten iron and powder flame spray. In the case of powder spraying, it is a spraying method in which powder is supplied from the upper part of the injector, mixed into the mixed gas of oxygen-fuel flowing through the injector supply port, sprayed at the nozzle outlet, and the molten particles collide with the surface of the substrate to coat.

The explosion-detonation (Gun Dpraying, D-Gun Spraying) consists of a long tube of about 25mm in diameter to be water-cooled, a working gas supply unit, an ignition device and a powder supply unit. In this method, oxygen and acetylene are supplied to a tube, powder is injected, and gas is exploded and burned to create a high-temperature, high-speed flame, which is used as a heat source to melt the powder and to accelerate and coat the molten particles. Due to the high flying speed of the thermal spray particles, a dense and highly bondable coating can be obtained. The maximum temperature of the flame was 4500 ° C, the flying speed of molten particles was 750-900 m / sec, and the ignition speed was 1-15 cycle / sec.

The high-velocity oxygen fuel spraying (HVOF) is a high-speed jet by burning a fuel gas (propane, methylacetylene, heptane, hydrogen) at high pressure with oxygen. The powder is injected into the jet as feed gas, and the working gas is burned in the combustion chamber and injected out of the torch through the nozzle. The temperature of the flame was 3170 to 3440 ° Ｋ and there was a disadvantage that the spray or the oxide can not be sprayed.

Arc spraying is a technique of forming a film by using two wires as electrodes, generating arcs at the electrode ends to melt the material, and simultaneously spraying and flying them with a compressed air jet. Since the arc furnace material is melted, high-efficiency spraying is possible, and it is suitable for film formation of large materials and overlay spraying of consumable materials. On the other hand, the thermal spraying material requires conductivity, and since the composition of the material is changed by the arc heat, it is necessary to use a wire rod whose composition is adjusted in advance. By spraying wires and powder materials such as thermal spray materials (metals, nonmetals, alloy steel, ceramics, plastics), etc. By blowing it hard to form a coating layer on the surface of the material, it significantly increased the wear resistance, corrosion resistance, heat resistance, chemical resistance, etc. of parts and products, and also imparted electric conductivity, insulation, thermal conductivity control properties, and used for surface softening and gap maintenance.

The Atmospheric Plasma Spraying is a plasma formation of argon (Ar), helium (He), nitrogen (N2) and the like gas into an arc, and discharged from the nozzle to form a film using a very high-temperature, high-speed plasma jet as a heat source Technology. The plasma generator is composed of a circular anode made of Cu and a cathode made of W, in which the electric arc discharge turns the working gas into plasma to form a jet. Flame temperatures range from 10,000 to 15,000 ° C, flame speeds range from 150 to 300 m / s, and enthalpy ranges from 16,000 to 20,000 J / l. Since it is an oxygen-free, carbon-free, clean, thermochemically active heat source, there is little contamination and change of the thermal spraying materials.However, depending on the type and condition of the thermal source, the temperature of the thermal spray particles and the contact time with the atmospheric gas components, especially the surface of the base metal, Energy, quench solidification rate, etc. are changed, that is, the physical and chemical properties of the thermal spray coating are greatly changed, and the ambient air is incorporated into the plasma jet flame in a process of atmospheric pressure, resulting in high porosity and weak adhesion rate. Oxides or nitrides are formed depending on the encapsulant to obtain a coating in which impurities are mixed.

The thermal spraying method is a method of melting and injecting a plating material by heat, and the metal powder supply pipe is disposed at right angles to the flow direction of the injection gas, thereby lowering the injection speed and unnecessarily plating the inside of the injection pipe, thereby reducing the service life. After all, the metal spraying method has a low injection speed of 200 ~ 1000m / sec, so that the porosity of plating film is about 10 ~ 30%, so it is not permanently plated and the surface temperature of steel structure to be plated by spraying. It is difficult to apply to the structure under load because it increases the.

In addition, the thermal spraying method of melting the metal is difficult to carry out the work of melting and spraying the wear material itself by heat in the case of removing a material other than the plating material, that is, the corrosion material such as the wear material. After spraying on the surface by spraying method, the work is expanded by replacing two different devices, which delays the time, and deforms by heat by spraying high temperature plating material on the surface of steel structure which is sensitive to sandblasting. There was a problem that occurred.

The main object of the present invention devised to solve the above problems is to explode fuel mixed air mixed with fuel and air in a state in which heat is not applied to the powder metal using a speed close to the supersonic speed of the injection gas injected at the explosive force. By spraying powder metal on steel structure with energy by spraying speed, it minimizes the porosity of powder metal plated with continuous pressure and suppresses thermal deformation in steel structure itself by spraying unheated powder metal. Maximize the effect of reinforcement and rust.

In addition, another object of the present invention is to increase the injection speed of the powder metal by preventing the dissolution of the metal powder by the air-cooled, water-cooled cooling method, or the explosion temperature of the combustion chamber by the combustion chamber and the injection gas injection section to explode the fuel mixture air It is possible to minimize the thermal deformation by attaching the powder metal to the steel structure with the injection gas in the cooled state by the pipe cooling method.

In addition, another object of the present invention is to cool the combustion chamber and the injection unit injecting the injection gas to explode the fuel mixture air in various ways to spray the powder metal by the injection speed of the injection gas, thereby greatly reducing the size and carry It is possible to increase workability in the field.

In addition, another object of the present invention is to spray by sputtering at a supersonic speed using a plated material that is not heated, and plated by using a material such as metal, plastic and sand having a low melting point in addition to the plated material as a substitute for the plated material. In addition, since various tasks can be performed, the general purpose of the device is to be expanded.

As such, when the mixture of vaporized air and fuel is transferred to the combustion chamber 133, the igniter 139 formed on one side of the combustion chamber 133 is ignited and exploded while the injection gas is formed and rises, and the upper outer periphery of the combustion chamber 133 is increased. When air is mixed into the mixing hole 133a formed as a through hole, the elevated injection gas is exploded again inside the lower part of the body part 110 and injected at a supersonic speed toward the injection hole 111 side of the body part 110.

At this time, the combustion unit 130 is formed to communicate with the air supply pipe 138 as a double partition wall of the outer wall 131 and the inner wall 132 to air-cool the combustion chamber 133 at the time of supplying air to the supply hole 137 and the combustion chamber ( The air superheated by the heat of 133 is mixed into the mixing hole 133a formed in the upper portion, so that the combustion unit 130 is cooled while the hot air and the exploded injection gas are combined to explode again to increase the thermal efficiency.

Take the spraying material supplied to) and spray it with the spraying gas to the steel structure to be worked on at the front side at supersonic speed.

At this time, the water supplied from the water supply pipe 124 formed in the lower portion of the injection unit 120 flows between the outer wall 122 and the inner wall 123 to cool the injection material supply pipe 121 formed in the center, the injection unit The outer wall 113 and the inner wall 114 of the body portion 110 as water flows through the circulation pipe 126 formed in a tubular shape to the upper front side of the injection port 111 of the body portion 110 from the rear upper portion of the 120. After cooling the body 110 while flowing to the space, it is formed to circulate while being discharged to the water discharge pipe 125 to cool the body 110 and the injection unit 120 with water.

By continuously pulverizing with the powder, the porosity is minimized, and even in the case of polishing, the foreign material is removed in a short time with a strong pressure to increase the efficiency.

When the spraying operation is completed, the lever 151 of the handle 150 is operated to block the air to move to the next work site in a state in which the operation of the supersonic launcher 100 is stopped, and the above operation is repeated.

 The supersonic launcher of the present invention devised to solve the problems described above does not apply heat to the powder metal using a speed close to the supersonic speed of the injection gas injected by the explosive force by exploding the fuel mixed air mixed with fuel and air. By spraying the powder metal on the steel structure with the energy of the spraying speed, the large metal structure or the old structure by minimizing the porosity of the powder metal plated with continuous pressure and suppressing the thermal deformation in the steel structure itself by the spraying of the unheated powder metal.
