Description

FIELD OF MANUFACTURING THE FIBER AND SHEET OF METAL AND INTERMETALLIC COMPOUND, USING PLASMA TORCH}

The present invention relates to a fiber and sheet manufacturing apparatus for metals and intermetallic compounds using a plasma torch, and more particularly, to supplying a quantitatively supplied raw metal to a rotating wheel by melting the plasma using a torch. Of high efficiency low pollution burner, electromagnetic shielding, electrostatic discharge, concrete reinforcement and composite materials for plasma and sheet metal manufacturing apparatus of metal and intermetallic compound using plasma torch for high purity metal fiber will be.

In general, metal fiber has the characteristics of metal and the flexibility of the fiber, so it has a wide range of fields such as filtration device, filter, high efficiency low pollution burner, electromagnetic shielding, electrostatic discharge, concrete reinforcement, and composite material which are applied under harsh environment. It has been put into practical use.

In particular, applications are widely applied in fields requiring a large surface area per unit volume, such as fuel cell electrodes, chemical reaction catalysts, and exhaust gas filtration devices.

Existing metal fiber manufacturing process adopts plastic deformation such as Bundle Drawing and Vibration Cutting as the main manufacturing methods, Single Roll Melt Spinning, Melt Extraction, Melt It is manufactured by adopting Rapid Solidification as a basic process such as drag dragging and dual roll melt spinning.

Among these basic processes, the bundle drawing method and the single roll melt spinning method are the representative metal fiber manufacturing processes that have been successfully applied to mass production and produce actual products.

In the case of the bundle drawing method, the same metal fiber as the constituent of the raw material can be manufactured, and the physical-chemical properties of the metal fiber are the same as those of the bulk material, so that the quality of the metal fiber is known to be the best and the actual metal fiber Mainly applied to various manufactured parts.

However, as the actual heat-treatment process for excessive plastic deformation and recovery proceeds in combination, the production cost increases exponentially, and the raw material price is about 3000 won per kg based on stainless steel 304. The price is very high, with more than 100 times the price.

In addition, the melt spinning method, which is one of the rapid solidification processes, can be applied to a rapid solidification process by directly injecting an existing material into a roll rotating at high speed in a molten state to form a plate or a wire rod, which is required for manufacturing a high strength lightweight alloy. It can be applied to the strip manufacturing process in the form of powder or ribbon,

Its advantages include the simple production process and low manufacturing cost per unit weight. However, the melt spinning method requires a large amount of additional equipment such as a melter and the evaporation of alloying elements in raw materials due to the difference in vapor pressure during working in vacuum. Due to the composition of the raw material and a metal fiber can be produced in a different form, there is a disadvantage that the adjustment of the diameter ratio of the length of the metal fiber is not easy and the product quality is not uniform according to the injection speed.

In particular, the melt spinning method has a disadvantage in that it is difficult to mass-produce or produce products by precise quality control, and has a disadvantage in that it is not suitable for high melting point metals due to the limited lifetime of nozzles for injecting molten metal.

In addition, the melting method used in the conventional melt spinning method is mainly an induction heating method by induction, and this heating method is a high vacuum in order to prevent oxidation during melting of the metal and nonmetallic material in the chamber, that is, the heating atmosphere. There is a problem that must be kept in a state,

Moreover, the heating method using the high frequency induction coil is not only difficult to control the temperature of the metal rod by simply outputting, but also causes a sudden change in temperature.

In particular, when using a thermocouple for measuring the temperature of the molten metal, the magnetic field and the high frequency generated by the induction coil may cause a malfunction of the thermocouple, and when the temperature is measured by an optical method, the molten metal is induced Since it is blocked by the coil, there is a problem that the area that can be measured is extremely limited.

In addition, due to the vibration caused by the peripheral device and the disk rotation and the instantaneous temperature fluctuation, the molten metal inside the induction coil does not overcome its own weight and melts, and the supply of molten metal becomes unstable, resulting in a significant decrease in production efficiency. There are several problems.

In addition, Korean Patent Publication No. 2001-82884 discloses "Metal Fiber Manufacturing Apparatus and Method", but since it is used to dissolve the metal plate material has the advantage of simplifying the installation compared to the prior art, in the case of one rotating disk Although no current flows on the molten metal sheet and the disk blades due to the induced electromotive force generated in the induction coil, the adjacent disk blades are alternated by numerous alternating induced electromotive forces when there are molten metal sheets on the blades. It is known that a circuit is formed between the molten metal plate and the current flows, so that a spark phenomenon occurs at the contact portion and metal fiber is not continuously formed, and metal fiber is cut or granulated. .

In order to solve the above problems, the present invention melts down by using a thermal plasma torch that is quantitatively controlled and supplied with a thermal plasma torch that is instantaneously melted even when a workpiece (material) is continuously inserted due to high instantaneous energy (heat). Alternatively, the plasma torch is used to produce high-purity metal fibers that are applied to a wide range of areas such as filtration devices, filters, high efficiency low pollution burners, electromagnetic shielding, electrostatic discharge, concrete reinforcement, and composite materials. It is an object of the present invention to provide a fiber and sheet manufacturing apparatus for metals and intermetallic compounds.

In another aspect, the present invention is the fiber and sheet manufacturing apparatus of the metal and intermetallic compound using a plasma torch, characterized in that the melt discharge port is penetrated through the lower side of the melting chamber to supply the melt to the molten metal is installed on the outside thereof. To provide

It is to provide a fiber and sheet manufacturing apparatus of a metal and intermetallic compound using a plasma torch.

The melting chamber is a primary reaction tank equipped with a dust collector to collect and purify the inert gas discharged for purification and recycling of the inert gas used and used therein, a cooling tank for cooling the inert gas purified therefrom, and cooling therefrom. Fiber and sheet production of metal and intermetallic compounds using a plasma torch, comprising: an inert gas purification tank for purifying the discharged inert gas with high purity; and a storage tank for storing the inert gas purified and discharged therefrom Provide the device.

On the other hand, the present invention is an inert gas purification tank for collecting and purifying the inert gas discharged for the purification and recycling of the inert gas blown in the manufacturing chamber installed so that the high-speed rotary roll is rotatable, and is purified and discharged therefrom It is to provide a fiber and sheet manufacturing apparatus of a metal and intermetallic compound using a plasma torch, characterized in that it comprises a reservoir for storing an inert gas.

It provides a fiber and sheet manufacturing apparatus of metal and intermetallic compound using a plasma torch, characterized in that it comprises a monitoring window.

Thermal plasma generated in the plasma torch applied to the present invention is a partially ionized gas mainly composed of electrons, ions, and neutral particles (atoms and molecules) generated by arc discharge, and is known as Local Thermodynamic Equilibrium. By maintaining their state, the particles all form a high-speed jet flame with the same temperature, ranging from thousands to tens of thousands of degrees Celsius.

By utilizing the characteristics of thermal plasma having high temperature, high heat capacity, high speed, and a large amount of active particles, it is used as a high temperature heat source or physicochemical reactor that is various and efficient and clean in the environment. have.

At present, thermal plasma technology is divided into materials, industrial equipment manufacturing process, waste treatment and recycling, and the material processing technology is used to create new materials, produce and process new materials using thermal plasma, and use plasma spray for surface hardening. It is used in coating, plasma coating (PVD), thermal plasma chemical vapor deposition (TPCVD), etc., and is widely used in industrial fields such as cutting, welding and melting of metal.

Waste treatment technology is an environmental technology that solves pollution problems by destroying harmful substances and reducing volume by pyrolyzing or vitrifying household and industrial wastes using high temperature and high temperature plasma incinerators.

In the above processes, the thermal plasma generator is used as a heat source to induce physical phase change by melting and vaporizing a target material at high temperature and high temperature, or to promote chemical reaction by radicals such as ions, excited atoms and molecules generated. Often acts as a chemical reactor.

Such thermal plasma technology overcomes limitations in the fields of materials, electrical and electronics, general machinery, automobiles, aviation, shipbuilding, steelmaking, textiles, printing, nuclear power, power, chemical, medical, and environmental industries. It is emerging as a very important high technology in the upcoming 21st century because it can play a key role in creating new technology, efficient use of energy, improving productivity, minimizing pollution and enhancing economic efficiency.

The generation of thermal plasma used in the plasma process as described above may be performed by direct current arc (DC Arc) discharge shown in FIGS. 1A and 1B, or high frequency inductive coupling shown in FIG. Coupled) discharge.

In principle, all of them generate a strong electric field in the target gas, so that sufficient charge particles are generated by successive collisions of accelerated electrons, leading to dielectric breakdown with electrical conductivity, thereby maintaining a plasma state with an arc discharge with high current flow. .

In the case of the DC arc torch shown in (A) and (B) of FIG. 1A, the electric field is directly applied to the cathode 53 installed inside the nozzle 50 of the anode, whereas the DC arc torch shown in FIG. The inductively coupled plasma torch differs from using an induction electric field resulting from a magnetic field change by the high frequency coil 57 without an electrode.

As the used gas 52, inert gases such as Ar and He, N2, H2, and air are commonly used, but depending on the type of process, O2, water vapor, hydrocarbon gas (CnHm), or reactants according to chemical processes may be mixed. .

A DC arc electrode of a plasma torch that is generally used is a rod-type cathode 53 of several kW to 1 MW class shown in FIGS. 1A and 1B, but several tens of kW to 10 MW class shown in FIG. It can be divided into two types using the hollow electrode (60, 61) of the two, they are again between the two electrodes inside the torch or using the torch electrode 50 and the process object 56 as one electrode Depending on the arc discharge method, it is divided into non-transferred (A) and non-transferred (B).

The characteristic of the transfer arc plasma torch is that the arc is generated outside the torch because the plasma is generated between the electrode inside the torch and the electrode outside the torch, so the temperature is very high near the object to be treated. The energy is transferred directly, so the thermal efficiency is very high.

In particular, in the case of a transfer arc plasma torch, a conductive object may be replaced with a positive electrode, or a separate positive electrode may be installed at the bottom of the reactor.

On the other hand, the non-conveying arc plasma torch has a disadvantage in that when the positive electrode and the negative electrode are installed in the torch and the gas is plasmaized, the reaction occurs between the positive electrodes, which is less thermally efficient and has a shorter temperature region than the transfer plasma torch. .

In the process of applying a plasma torch, it is usually operated at a pressure of 50 to 10,000 A arc current and a pressure of 0.1 to 5 atm to generate a jet flame of 5,000 to 20,000 K and 500 to 2,000 m / s in local thermal equilibrium. There are various designs of torches with electrode-like arrangements, depending on how to stabilize the controlled flame of the desired shape.

The Wall Stabilization method limits the generation of long arcs in a cylindrical cooling tube, which increases the thermal conductivity towards the wall even if the arc column is biased towards the wall of the tube, resulting in a decrease in electrical conductivity with temperature reduction, and the arc column again in its original form. It is returned to the equilibrium position and stabilized.

In vortex stabilization, when a gas is injected in a tangential direction to form a vortex between two electrodes, an arc discharge is performed while the cold gas is driven to the wall and the hot gas is thermally well protected due to the centrifugal force difference. It is stabilized in a contracted form along this axis.

Arcs, which are flows of high current, naturally generate a magnetic field around them, or when a magnetic field is applied outside the torch, balances the drag force of the plasma fluid by the Lorentz force (j × B) caused by this magnetic field and the arc current. Magnetic stabilization of the arc in the form of contraction by force directed toward the axis, and the arc spot is not fixed to one point on the electrode surface, causing rotation to erode the electrode material. This can be alleviated to extend the life of the electrode.

In general, the rod-type cathode 53, which requires a lot of hot electron emission and a high melting point, is most commonly used with a material containing about 2% of ThO2 in W, and may also add LaO2, CeO2, Y2O3, or 0.1% LaB6. As the nozzle anode 50 or the cavity type electrodes 60 and 61, high purity oxygen-free copper having good thermal and electrical conductivity is mainly used as the electrode material.

As a high frequency torch, a capacitively coupled type requires a very high frequency for generating a thermal plasma due to a discharge caused by a displacement current. In an inductively coupled torch, three or seven induction coils (57) are wound around an air or water-cooled crystal tube or ceramic tube and connected to a high frequency power source in the range of 100 kHz to 100 MHz through an impedance matching circuit. After thermal insulation of the injected azimuthal electric field, the thermal plasma is generated while maintaining the discharge by driving the circular current in the opposite direction to the induction coil current.

Due to the high electrical conductivity of the plasma and the skin effect caused by the high frequency magnetic field, the plasma temperature distribution due to the induced electric field distribution and the resulting ohmic resistance heating has a radial distribution with the peak peak off the axis and biased toward the tube wall. It will show a flame in the form of an annular shell. This is a noticeable difference from the shape of a focused jet flame with a sharp peak in diameter and axial direction with a peak at the axis seen in the DC arc torch.

Since the high frequency torch operates at a lower power (several to 200 kW) than the DC arc torch, the flame has an elongated rugby ball shape with a temperature and speed of less than 10,000 K and less than 100 m / s. Thermal plasma is generated and its cross-sectional area is 40-50 times larger than that of a direct-current plasma jet, so the temperature and velocity change flux is relatively slow, and the reactant with the plasma can stay in the flame for a relatively long time to transfer more momentum and energy from the plasma. I can receive it. In addition, various gases, liquids, and solid forms of reactants may be evenly mixed in the plasma, which is particularly advantageous as a chemical reactor, but has a disadvantage in that the torch thermal efficiency remains at 40 to 50%, which is much lower than 60 to 85% of direct current.

Hybrid torches in the form of connecting a DC torch and a high frequency inductively coupled torch in series produce a large volume of plasma flame with a gentle temperature seal, and can compensate for the disadvantages of the process using each torch. There are also attempts to improve. Recently, the generation of thermal plasma showing local thermal equilibrium characteristics by surface traveling wave discharge at 0.1 atm or higher using microwaves up to 10 GHz has been studied, but a high power microwave source is required due to the high loss, and thus it has not been applied to the process.

Figure 2 is an enlarged cross-sectional view of the nozzle portion of the transfer plasma DC arc torch applied to the present invention.

Therefore, in the present invention, the temperature control is easy as a heat source for melting the raw material, has a low operating cost and does not affect the optical sensing means such as a camera, and introduces a plasma torch capable of automatic control, the transfer type as shown in FIG. Arc plasma torch was applied.

The reason why the transfer arc plasma torch is applied is that energy can be directly transmitted by using a material to be treated (a material to be melted) as an electrode, which enables low-cost operation due to energy saving and good thermal efficiency.

As shown in Figure 2, the transfer arc plasma torch applied in the present invention is a tip (Tip) of the cathode 67 is formed of a tungsten (W) material,

The cathode 65 is made of stainless steel (STS) and the outer 66 is made of copper (Cu), and cooling water is supplied to the space of the electrode 65. The cooling water is discharged (75) between the inner (65) electrode and the outer (66) electrode.
