FIG. 9 is a front perspective view showing that each predetermined electromagnetic waves does not conflict in the runner device capable of heating a melt through selective radiating of electromagnetic waves according to an embodiment of the present invention.

[0051] As shown in FIG. 1, the runner device capable of heating the melted material by using selective radiation of electromagnetic waves according to the present invention is to be cast in the casting mold 3 by utilizing the runner device 1 to manufacture it in a shape of a certain unit size.

[0052] Here, Ferro-silicon or ferro-manganese is a ferro alloy used in the manufacture of steel or cast iron. Ferro-silicon is used as a deoxidizing agent and reducing agent, and is used as a graphitization accelerator in carbon steel.

[0053] In general, the melt can be made by a process of pouring directly from the melting furnace 2 to the casting mold 3 in the process of being provided from the melting furnace 2 to the casting mold 3.

[0054] In the conventional structure, the melt of the melting furnace 2 is limited to a structure in which the melt flows along the elongated pipe-shaped refractory material.

[0055] In the case of the runner device capable of heating the melted material by using selective radiation of electromagnetic waves according to the present invention, in order to prevent the melt provided from the melting furnace 2 from being cooled while flowing into the casting mold 3, a predetermined electromagnetic wave is applied to the melt for minimizing thermal loss of the melt by irradiating the melt flow while maintaining a constant temperature.

[0056] As shown in FIG. 2, the runner device capable of heating the melted material by using selective radiation of electromagnetic waves according to the present invention comprises a heating unit 100, a heating storage unit 200, and a radiating unit 300.

[0057] As shown in FIG. 3, the heating unit 100 provides a path for the melt flowing out from the melting furnace 2 to flow, and is configured to heat the melt to a predetermined temperature.

[0058] The heating unit 100 delivers the melt provided from the melting furnace 2 to the casting mold 3, and at this time, the melt is heated to a predetermined temperature by generating a predetermined heat so that the melt is not cooled, and let the temperature be maintained.

[0059] The predetermined temperature referred to herein is a temperature above the melting point or melting point of the melt, and may be defined as a temperature at which the melt is not cooled.

[0060] In addition, since the heating unit 100 is configured to receive the melt from the melting furnace 2 for the first time, it is preferable that the heating unit 100 is made of a material corresponding to heat resistance and a refractory material. Here, the heat-resistant, 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, and a metal or ceramic material may be typically applied.

[0061] For example, the heating unit 100 is preferably a silicon carbide (SiC) compound in which silicon and carbon are combined in a 1:1 ratio. In addition, the heating unit 100 can generate a predetermined heat by itself as a predetermined electromagnetic wave is irradiated by utilizing the characteristics of the already commercialized silicon carbide, and a detailed mechanism thereof will be omitted.

[0062] As shown in FIG. 3, the heating unit 100 of the runner device capable of heating the melted material by using selective radiation of electromagnetic waves according to the present invention comprises a heating plate 110, a first spread part 120, and the second spread part 130.

[0063] First, one side of the heating plate 110 is disposed adjacent to the melting furnace 2 and the heating plate 110 is configured to form a predetermined path so that the melt flowing out from the melting furnace 2 is melted.

[0064] The heating plate 110 is composed of an upper part and a lower part, and the upper part forms an abrupt inclination, and one side is adjacent to the melting furnace 2 and rapidly flows the melt flowing down from the melting furnace 2. The lower part is a gentle slope and can form same strength as the horizontal surface.

[0065] The molten material can flow along an inclination from the top to the bottom of the heating plate 110.

[0066] In addition, when a predetermined electromagnetic wave is selectively irradiated from the radiating unit 300 to the heating plate 110, the predetermined heat is generated by interaction with the predetermined electromagnetic wave. The predetermined heat of the heating plate 110 may cause the melt to be maintained at a predetermined temperature.

[0067] That is, the predetermined heat of the heating plate 110 is thermally conducted to the melt, so that the melt can be at a predetermined temperature.

[0068] The first spread part 120 is stacked so that a part of it is exposed on the lower surface of the heating plate part 110, and forms wrinkles along the flow direction of the melt, so as to first disperse the falling melt.

[0069] The second spread part 130 is stacked so that a part of it is exposed on the lower surface of the first spread part 120, and forms a wrinkle opposite to the first spread part 120, so as to second disperse the falling melt from the first spread part 120.

[0070] It is preferable that the second spread part 130 forms a wrinkle opposite to that of the first spread part 120.

[0071] As shown in FIG. 2, the heating storage unit 200 selectively covers the heating unit 100 and selectively prevent thermal loss of the melt so that the melt maintains a predetermined temperature.

[0072] The heating storage unit 200 prevents heat generated by the predetermined electromagnetic wave in the heating plate unit 110 from being lost, so that the molten material can maintain a predetermined temperature.

[0073] The heating storage unit 200 forms an outer wall on the outside of the heating unit 100 in the height direction, and also forms an outer wall on the upper and lower portions to prevent heat emitted from the melt from escaping to the outside of the runner device 1, and maintains the temperature inside the unit 100 to minimize the thermal loss of the melt.

[0074] The heating storage unit 200 is preferably made of a material having heat resistance and fire resistance, for example, a fire resistant block or a heat insulating block.

[0075] The heating storage unit 200 of the runner device capable of heating the melted material by using selective radiation of electromagnetic waves according to the present invention comprises a thermo retention part 210, an insulator 220 and a protecting barrier 230.

[0076] As shown in FIG. 4, the thermo-retention part 210 selectively forms an outer wall to surround a predetermined path formed by the heating plate unit 110 and selectively covers the heating plate 110, so that the temperature of the melt raised to a predetermined temperature is maintained by the predetermined heat generated from the heating plate unit 110.

[0077] The thermo-retention part 210 includes a thermo-loop part 211, a thermo-side part 212, a thermo-floor part 213, and a thermo-arch part 214.

[0078] The thermo-loop part 211 is disposed on the upper part of the thermo-retention part 210 and cover the upper part of the heating unit 100 to maintain the temperature of the melt.

[0079] The thermo-side part 212 is disposed on both sides of the thermo-retention part 210 to cover the left and right sides of the heating unit 100 so that the temperature of the melt can be maintained.

[0080] The thermo floor unit 213 is disposed under the thermo retention unit 210 to cover the lower portion of the heating unit 100 so that the temperature of the melt can be maintained.

[0081] In the case of the thermo-arch part 214, it is disposed on the front side of the thermo-retention part 210, and is disposed adjacent to the outlet flowing from the heating unit 100 and provided to the casting mold 3, so that the temperature of the melt can be maintained in the process of that the melt is provided in the casting mold 3.

[0082] As shown in FIG. 5, the insulating unit 220 selectively forms an outer wall covering the thermo-retention part 210 and prevent a predetermined heat generated from the heating plate unit 110 from being diffused to the outside.

[0083] The insulator 220 can cover the thermo-retention part 210 covering the heating unit 100 to prevent heat from spreading to the outside.

[0084] The insulator 220 includes an insulating side part 221, an insulating floor part 222, and an insulating cross part 223.

[0085] The insulating side part 221 is disposed on both sides of the thermo-side part 212 to cover the thermo-side part 212 to prevent heat diffusion.

[0086] The insulating floor part 222 is disposed under the thermo-floor part 213 to cover the thermo-floor part 213 to prevent heat diffusion.

[0087] The insulating cross part 223 is disposed between the insulating side part 221 and covers the upper portion of the thermo-arc portion 214 to prevent heat diffusion.

[0088] As shown in FIG. 6, the protecting barrier 230 selectively covers both sides of the insulator 220 and selectively forms a plurality of openings 230h.

[0089] The protecting barrier 230 forms an outer wall on both sides of the insulator 220 in the height direction, and has a plurality of openings 230h.

[0090] In addition, the protecting barrier 230 is disposed under the insulating unit 220 in the width direction and may have a plurality of openings 230h.

[0091] A predetermined electromagnetic wave generated from the radiating unit 300 may be irradiated to the heating unit 100 through the plurality of openings 230h of the protecting barrier 230.

[0092] The plurality of openings 230h of the protecting barrier unit 230 are an entrance to which a predetermined electromagnetic wave is irradiated and are irradiated in an inward direction toward the heating unit 100. That is, the predetermined electromagnetic wave generated from the radiating unit 300 can be irradiated only through the plurality of openings 230h, and the predetermined electromagnetic wave irradiated to the heating unit 100 is to be prevented from leaking to the outside.

[0093] In addition, the protecting barrier 230 is preferably made of a metal material capable of blocking a predetermined electromagnetic wave in order to prevent the predetermined electromagnetic wave irradiated by the heating unit 100 from leaking to the outside.

[0094] As shown in FIG. 6, the radiating unit 300 is selectively provided to the heating storage unit 200, and selectively irradiates the predetermined electromagnetic wave directly toward the heating unit 100 so that the melt is at a predetermined temperature.

[0095] The radiating unit 300 of the runner device capable of heating the melted material by using selective radiation of electromagnetic waves according to the present invention comprises a wave generator 310, a wave guider 320, a cooler 330, and a bridge part 340.

[0096] As shown in FIG. 7, the wave generator 310 is selectively disposed in the plurality of openings 230h of the protecting barrier unit 230, and generates the predetermined electromagnetic wave.

[0097] The wave generator 310 could generate the predetermined electromagnetic wave by using the same or similar configuration and principle as that of a commercially available magnetron, and a detailed mechanism thereof will be omitted.

[0098] The wave guider 320, as shown in FIG. 7, is disposed on one side of the plurality of wave generators 310a. The wave guider 320 is a plurality of configurations that selectively transmit a predetermined electromagnetic wave generated from the plurality of wave generators 310 to be irradiated to the heating plate 110 through the opening 230h.

[0099] The wave guider 320 transmits a predetermined electromagnetic wave generated from the wave generator 310 to the heating unit 100.

[0100] The wave guider 320 is individually installed in each of the wave generators 310, and allows the wave generator 310 to form preset angles independently of each other.

[0101] In addition, one side and the other side of the wave guider 320 are formed at different angles so that the wave generating unit 310 can be formed at a preset angle. For example, as shown in FIG. 8, the preset angle is formed as e 1 as in FIG. 8(a), and a predetermined electromagnetic wave may be irradiated in the a direction. In addition, when the preset angle is formed as e 2 as shown in FIG. 8(b), a predetermined electromagnetic wave may be irradiated in the b direction. That is, it is possible to selectively control the direction in which a predetermined electromagnetic wave is irradiated according to a preset angle.

[0102] In addition, the plurality of wave guiders 320 are disposed to cross each other, so that each of the predetermined electromagnetic waves generated from the plurality of wave generators 310 are selectively irradiated so as not to conflict with each other.

[0103] For example, as shown in FIG. 9, when the predetermined electromagnetic wave generated from the wave generator 310 selectively present on the left, right, or lower side of the heating unit 100 is directed toward the heating unit 100, if the left and right wave generator exist symmetrically, collisions among the electromagnetic waves may occur.

[0104] At this time, when the electromagnetic waves collide, the generated collision energy may cause overall damage to the runner device 1 such as the heating unit 100, the heating storage unit 200, or the radiating unit 300 so the function of the runner device 1 is broken due to the collision.

[0105] Therefore, it is preferable that the predetermined electromagnetic waves irradiated by the plurality of wave generators 310 are arranged to be crossed with each other in order to be misaligned, that is, not to conflict with each other.

[0106] The cooler 330 is selectively disposed on the other side of the wave generator 310 to cool a predetermined heat generated from the wave generator 310 when a predetermined electromagnetic wave is generated.

[0107] For example, when the wave generator 310 generates a predetermined electromagnetic wave, heat is generated. If the generated heat continues, the wave generator 310 may fail.

[0108] Accordingly, the cooler 330 serves to cool the heat of the wave generator 310 in order to prevent failure or damage to the wave generator 310.

[0109] As shown in FIG. 7, in the case of the bridge part 340, one side of the bridge part 340 is provided to the wave guider 320, and the other side of the bridge part 340 is provided to the wave generator 310 to interconnect the wave guider 320 and the wave generator 310.

[0110] The bridge part 340 is formed to protrude from the wave guider 320 to interconnect the wave generating parts 310, and by selectively adjusting the protrusion angle of the bridge part 340, a predetermined electromagnetic wave is controlled not to collide.

[0111] 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, the descriptions in parentheses are also interpreted as essential components.
