[0003] The working characteristics of the ore-fired furnace are that it uses refractory materials as the furnace lining, uses self-trained electrodes, inserts the electrodes into the charge for submerged arc operation, utilizes the energy of the arc and the current passing through the charge, and generates energy due to the resistance of the charge to melt the metal, gradually adds materials, and intermittently discharges iron slag. It is an industrial electric furnace that operates continuously.

[0005] However, when the existing submerged arc furnace is used for reduction smelting of ore, different types of materials are poured in all at once, which not only leads to low smelting efficiency, but also may result in incomplete smelting of the minerals.

However, when faced with materials of different densities, types, and volumes, the fixed electrode height may not be able to touch or the arc energy may not be fully supplied due to the small contact area.

[0026] 1. The device can screen and place different types of ore raw materials in order and time before smelting, and can crush the ore in advance, reduce the unit ore volume, achieve ore precision processing, and reduce the working time of the submerged arc furnace.
[0027] 2. The device can select the height of the energy supply electrode according to the amount of ore material, the type of ore material, the density of the ore material, and the volume of the ore material. The operation can be achieved by controlling the rotation direction of the second servo motor. The operation is simple and convenient. The height of the energy supply electrode can be adjusted so that the energy supply electrode is always at a centered and fully contacted height with the material when discharging through the electrode holder. The device can achieve better working efficiency when using the energy of the arc and the current passing through the charge to generate energy due to the resistance of the charge to melt the metal.
[0028] 3.

While the stability is better, it can be coordinated with multiple discharge tables, and the discharge port can be rotated to the discharge guide rail at the corresponding position as needed to unload the material.
[0029] 4. The device can control the volume and time of the material released by the unloading component, and cooperate with the transformer to control the energy release of the electrode holder and the energy supply electrode.

In this way, it can be ensured that the smelting energy supply component and the mineral material released by the unloading component are always in a state of high energy efficiency ratio and high efficiency.
[0030] 5. While the device controls the rotation of the main body of the submerged arc furnace to adjust the position of the discharge port corresponding to the discharge guide rail through the first servo motor, the smelted material inside the main body of the submerged arc furnace can also form a certain dynamic stirring relationship between the two stationary electrode holders, so that the ore material inside the main body of the submerged arc furnace can form a moving contact relationship with the energy supply electrode. Compared with static contact, it can form contact with multiple materials at the same time, which is more efficient. The melting speed of each piece of material is more uniform, which effectively improves the efficiency and yield of high-precision processing of the device.
[0031] 6. The two feeding pipes of different lengths in the device can rotate along with the first servo motor when the main body of the submerged arc furnace rotates, and can cooperate with the smelting energy supply component to form a certain dynamic stirring relationship for the material inside the main body of the submerged arc furnace, and according to the rising or falling amplitude of the energy supply electrode, that is, when the electrode rises, the material can be fed through the short feeding pipe, and when the energy supply electrode falls, the material can be fed through the long feeding pipe, so that the material can always be kept at the shortest vertical distance to the energy supply electrode when entering the main body of the submerged arc furnace, regardless of whether there is material inside the main body of the submerged arc furnace, better smelting efficiency can be achieved.

[0070] Further, additional embodiments;
[0071] On the basis of the original equipment, a pulverizer or crusher (not shown in the figure) can be installed inside the lower barrel 32 to pre-crush the ore, which not only speeds up the smelting efficiency inside the outer ring 11 of the furnace cover, but also prevents the material ore from clogging the feed pipe 35.
[0072] Working principle of the present invention: When the device is working, firstly, the control compartment 5 is the core output and input part of the control signal. The control compartment 5 can control any controllable power unit in the device. In the following description, all control structures are realized through the control compartment 5.
[0073] Open the slide cover 31 to put in the material, control the three-way valve 36 to rotate to the corresponding feed barrel 33, and choose according to needs. The short feed pipe 35 only contacts the upper half of the entire mineral arc furnace body 1, and the long feed pipe 35 contacts the bottom of the inner wall of the mineral arc furnace body 1. In this way, no matter whether there is molten liquid metal or only solid metal inside, the material can be put in. The length of the feed pipe 35 is different. When the liquid replenishing pipe 34 is replenishing the liquid raw material, it can be put into the upper surface or the bottom of the molten metal inside the mineral arc furnace body 1 for reaction as needed.

[0075] When slag or material needs to be discharged during smelting, the first servo motor 14 is controlled to rotate the gear disc 15, so that the gear disc 15 drives the electric arc furnace body 1 to rotate through the outer gear ring 12. Even after the discharge port 13 rotates to the top of the corresponding discharge guide rail 62, the valve inside the discharge port 13 is opened to discharge the material.
[0076] Different discharge guide rails 62 will be connected to different equipment. For example, they can be connected to various injection molding equipment and cooling equipment to enter the metal finished product warehouse after cooling. Any of the discharge guide rails 62 can be used as a slag discharge channel, connected to slag recovery and reuse equipment or directly discharged and discarded.
[0077] A top frame 63 is provided above each data screen 51, which can be used to pre-cool the device when the discharge guide rail 62 is connected to the discharge port 13 of the device and the feed port between the equipment, thereby shortening the working time of the device;
[0078] The operator transmits the signal to the control chamber 5 through the operation panel 52, and then the control chamber 5 transmits it to other components. The control chamber 5 transmits the opening and closing or operation of the device and the temperature value inside the main body 1 of the electric arc furnace to the data screen 51. Finally, the operator can understand the overall reaction of the device through the data screen 51.
[0079] The electronic components and models used in the present invention can be selected in different models and sizes according to the actual needs of use, and the selected model can realize the functions that the parts need to realize in this application. For example, the control compartment 5 of this article is equipped with a control module, a signal receiving module and a signal transmitting module. These three modules are integrated inside the control compartment 5 and are interconnected on the circuit board. Each module can adopt a model that can realize the function on the market, and the size of each module can ensure that the three modules can be fully integrated inside the control compartment 5.
