When the steel auxiliary material such as ferro alloy is input, the heating body unit 100 heats them to a predetermined temperature in order to melt them.
The predetermined temperature referred to herein is a melting point or a temperature above the melting point of the melt, and may be defined as a temperature for melting the melt.
In addition, the heating body unit 100 is configured to maintain a high temperature in order to melt the melt, and its properties are preferably made of a material corresponding to heat resistance and a refractory material. Here, the heat-resistant or refractory material is an ultra-high-temperature heat-resistant material that can withstand a high temperature of several hundred to several thousand degrees (° C.), several seconds to several thousand hours, so the heat-resistant or refractory material can be typically a type of a metal or ceramic material.
The heating body unit 100 of the furnace system for controlling of individual temperature through selectively radiating of electromagnetic waves according to the present invention, as shown in
As shown in
The heating container 110 forms a predetermined space to accommodate the melt therein, so that the melt can be dissolved.
When a predetermined electromagnetic wave is selectively irradiated from the radiating unit 300, the heating container 110 generates predetermined heat by interaction with the predetermined electromagnetic wave, and through the generated predetermined heat, raises the temperature of the melt above a predetermined temperature.
Preferably, the heating container 110 is preferably a silicon carbide (SiC) compound in which silicon and carbon are combined in a 1:1 ratio. Utilizing the properties of silicon carbide that have already been commercialized, the heating container 110 can generate a predetermined heat by itself when a predetermined electromagnetic wave is irradiated, so a detailed mechanism thereof can be omitted.
In addition, as the predetermined heat generated in the heating container 110 is thermally conducted to the melt, and then the melt is heated to a predetermined temperature or higher to be dissolved.

As shown in
The heating sensing unit 400 is selectively disposed at a predetermined point of the heating container 110, and is configured to selectively measure the temperature at the predetermined point to calculate predetermined temperature in real time.
The predetermined point referred to herein is at least one or more points, and may be determined differently depending on the height of the heating container 110.
For example, the heating container unit 110 is divided into an upper layer, a middle layer, and a lower layer, and the heating sensing unit 400 is fixedly attached to each position. Each of the temperature in the upper layer, the temperature in the middle layer, the temperature in the lower layer of the heating container 110 is measured. In addition, it is preferable that there is no limit to the location, number, and size of the predetermined points.
In addition, the reason for measuring the respective temperature of the predetermined point in the heating sensing unit 400 is to individually and independently control the temperature at the predetermined point according to the predetermined temperature.
For example, as shown in
The temperature information calculated by the heating sensing unit 400 is transmitted to the radiating unit 300 through an external server, and the radiating unit 300 receives the irradiation intensity, irradiation angle, irradiation time of a predetermined electromagnetic wave based on the temperature information.
The heating cover unit 200 is configured to selectively cover the heating body unit 100 to prevent a predetermined heat from being diffused to the outside so that the melt maintains a predetermined temperature.
In addition, the heating sensing unit 400 may utilize commercially available vision sensors, infrared sensors, ultrasonic sensors, position sensors, camera sensors, temperature sensors, and the like, so detailed mechanisms thereof can be omitted.
As shown in
In addition, the heating cover unit 200 forms an outer wall on the outside of the heating container unit 110 in the height direction, and is disposed to surround the heating container 110, so that the generated predetermined heat does not escape to the outside. By maintaining the internal temperature of the heating container 110, the thermal loss of the melt can be minimized, and the convection phenomenon can occur inside the heating container so that the melt can be uniformly dissolved.
The heating cover unit 200 is also preferably made of a material having heat resistance and fire resistance, for example, a fire resistant block or a heat insulating block.
The heating cover unit 200 of furnace system for controlling of individual temperature through selectively radiating of electromagnetic waves according to the present invention, as shown in
First, the holding barrier 210, as shown in
The block barrier 220, as shown in
The slot barrier 230, as shown in
As shown in
As shown in
Each of the slots of the slot barrier 230 is sealed by the radiating unit 300 to prevent a predetermined electromagnetic wave from leaking to the outside, and at the same time to allow the predetermined electromagnetic wave to be irradiated inwardly.
As shown in
The radiating unit 300 covers the plurality of slots 230a, and allows a predetermined electromagnetic wave to be irradiated only to the inside.
The radiating unit 300 of the furnace system for controlling of individual temperature through selectively radiating of electromagnetic waves according to the present invention, as shown in
The generator 310, as shown in
The generator 310 may generate a predetermined electromagnetic wave by using the same or similar configuration and principle as that of a commercially available magnetron, and a detailed mechanism thereof can be omitted.
As shown in
In addition, the guider 320 has a plurality of components such that a predetermined electromagnetic wave passes through the plurality of slots 230a and is irradiated to the heating container 110.
The guider 320 transmit a predetermined electromagnetic wave generated from the generator 310 to the heating body unit 100.
The plurality of guider 320 are separately installed in each of the plurality of generators 310, and allow each of the generators 310 to form predetermined angles independently of each other.
In addition, the guider 320 has one side and the other side formed at different angles so that the generator 310 can be formed at a predetermined angle.
As shown in
In addition, the plurality of guiders 320 are disposed to cross each other, so that predetermined electromagnetic waves generated from the plurality of generators 310 are selectively irradiated so as not to conflict or overlap each other.
For example, as shown in
When the electromagnetic waves collide each other, the generated collision energy may cause overall damage to devices such as the heating body unit 100, the heating cover unit 200 or the radiating unit 300, so the function of the furnace may be lost by the collision of the electromagnetic waves.
Therefore, it is preferable to arrange the plurality of generating units 310 to cross each other in order not to overlap the predetermined electromagnetic waves irradiated.
That is, a predetermined electromagnetic wave does not overlap according to the angle and arrangement relationship of the radiating unit 300, and the heating container unit 110 may generate heat. In addition, the angle of the radiating unit 300 is selectively adjusted so that the melt is uniformly dissolved in the heating container 110.
As shown in
At this time, the predetermined temperature measured at the predetermined point is selectively provided to each of the plurality of generators 310. It is preferable that the predetermined temperature sensed in the upper layer among the predetermined points selected from among the plurality of generators 310 is transferred to the generator 310 disposed on the upper portion of the radiating unit 300.
According to the interlocking of the radiating unit 300 and the heating sensing unit 400, the plurality of guiders 320 selectively receive the information of the predetermined point from the heating sensing unit 400, and the predetermined angle is determined in advance to allow the predetermined electromagnetic wave to reach the predetermined point.
For example, as described above, the predetermined temperature sensed in the upper layer among the predetermined points is transmitted to the generator 310 disposed above the radiating unit 300 among the plurality of generating units 310. The predetermined angle of the guider 320 provided to the generating unit 310 disposed thereon is selectively set so that the predetermined electromagnetic wave reaches the upper layer of the predetermined point.
Through the mutual interworking of the radiating unit 300 and the heating sensing unit 400, it is possible to control the intensity and irradiation angle of a predetermined electromagnetic wave according to the temperature information inside the heating container 110, so the predetermined electromagnetic wave is uniformly irradiated inside the heating container 110, and then the heating container 110 can be heated to a target temperature. Accordingly, the convection phenomenon of the melt existing inside the heating container 110 can be induced, and the melt can be uniformly melted, so that the effect of resolving the imbalance of the temperature difference according to the location occurs.
In the case of the cooler 330, as shown in
For example, when the generator 310 generates a predetermined electromagnetic wave, heat is generated, and if the generated heat continues, the generator 310 may fail.
Accordingly, the cooler 330 serves to cool the heat of the generator 310 in order to prevent failure or damage of the generator 310.
In the case of the bridge 340, as shown in
The bridge 340 is formed to protrude from the guider 320 to interconnect the generators 310. With selectively adjusting the protrusion angle of the bridge 340, a predetermined electromagnetic wave can be controlled so as not to collide.
The scope of the present invention is determined by the matters described in the claims, and parentheses used in the claims are not described for selective limitation, but are used for clear components, and descriptions in parentheses are also interpreted as essential components.
