Description

Technical Field

[0001] The present invention relates to the technical field of ore refining, and in particular to a metal oxide ore refining furnace with intelligent temperature control. Background Art

[0002] Metal oxide ores are widely present in nature, but they usually appear in the form of complex mixtures, contain a large amount of impurities, and the content and existence form of metal elements are not conducive to direct application. In order to obtain high-purity and good-performance metals, they must be processed with the help of refining furnaces. Refining furnaces can use high temperature, chemical reactions and other means to promote the reaction between metal oxides in the ore and reducing agents, reduce the metal from the oxide, and separate and remove impurities, thereby obtaining metal products that meet industrial standards.

[0003] Existing metal oxide ore refining furnaces have various stirring methods. The most common one is mechanical stirring, which involves installing stirring blades in the furnace and using a motor to drive the blades to rotate, so that the materials in the furnace are mixed evenly and the reaction rate is accelerated. This method can more intuitively control the stirring intensity and range, but the stirring blades are easily affected by the high temperature and highly corrosive furnace environment, resulting in severe wear and tear, requiring frequent replacement and maintenance. There is also gas stirring, which introduces inert gas or reaction gas into the furnace and uses the flow of gas to drive the materials in the furnace to tumble and mix, avoiding the wear of mechanical components in harsh environments. However, the gas flow and distribution are difficult to accurately control, resulting in local uneven stirring.

[0004] Traditional refining furnaces have a single stirring method, mostly relying on simple mechanical stirring, which makes it difficult to achieve all-round and refined processing of materials. Taking the common paddle stirring as an example, its stirring range is limited. In the corners and edge areas inside the furnace body, the materials are difficult to be fully stirred, resulting in insufficient mixing of ore and molten metal in these locations, affecting the uniformity of the reaction. The traditional stirring method is not efficient enough to turn the materials in the furnace, and the problem of uneven heating of the materials is prominent. Some materials are in the high temperature area for a long time, while some are insufficiently heated, resulting in incomplete reaction, waste of energy, and reduced quality of refined products.

[0020] Since the electric furnace used to produce manganese iron alloy is called manganese iron alloy refining furnace, also known as reduction electric furnace, it is mainly used for the reduction smelting of metal oxide ores. At the same time, because the electrodes of this refining furnace are deeply inserted into the charge and the arc is buried under the charge, it is also called submerged arc furnace or submerged arc furnace. At present, the automatic control of the refining furnace still remains at the level of manual operation. Such production conditions require operators to read the values indicated by the on-site instrument in real time to obtain the required electrical parameters, thereby guiding the manual adjustment of the electrode lifting. Due to the lack of standardization of manual operation and the effectiveness of the refining furnace electrode adjustment often depending on the personal experience of the operator, the furnace condition cannot be stabilized for a long time, thereby affecting the quality and output of manganese iron alloy products and causing low efficiency and instability in the entire production process. Therefore, at the temperature control level, through the collaboration of high-precision temperature sensors and intelligent control systems, real-time and accurate monitoring and regulation of the temperature of each area in the furnace can be achieved to ensure the temperature Fluctuations are strictly limited to a preset range, creating a stable and suitable thermal environment for the reduction smelting of metal oxide ores.

DETAILED DESCRIPTION

[0032] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0033] Example 1

[0034] According to one embodiment of the present invention, Figure 9A metal oxide ore refining furnace with intelligent temperature control, and a method for intelligent temperature control thereof, comprising the following steps:

[0035] S1: Temperature sensing module: High-precision temperature sensors are evenly arranged in the manganese ferroalloy refining furnace to collect temperature data from various areas in the furnace in real time and quickly transmit it to the intelligent control system to provide basic information for temperature control;

[0036] S2: Electrode control module: Based on the electrode diameter, the distance between the electrode end and the furnace bottom is controlled to about 0.9 times its diameter. The insertion depth is adjusted according to factors such as the material surface height, and the coke feeding amount is reasonably controlled to ensure a reasonable temperature distribution.

[0037] S3: Pressing and releasing operation module: Pressing and releasing the electrodes according to the standard instructions, controlling the daily pressing and releasing degree to about 20mm, and not pressing and releasing 30 minutes before and when leaving the furnace to maintain temperature stability during the production process;

[0038] S4: Voltage and current control module: This module uses a higher secondary voltage to increase the power input to the furnace, controls the electrode working section to about 1.7m, maintains the balance of the three-phase electrodes and inserts them deep into the furnace, so that the furnace reaches the appropriate temperature and improves the smelting effect. At the same time, it adopts a peak production strategy, adjusts the furnace load and input voltage level according to the electricity price, and reduces energy consumption.

[0039] S5: Intelligent temperature regulation module: The intelligent control system automatically adjusts the power of the heating element based on the preset optimal temperature curve and compares it with the real-time temperature data. When the temperature inside the furnace is lower than the set value, the heating power is increased; when it is higher than the set value, the power is reduced to control the temperature fluctuation within the preset range.

[0040] S6: Stirring auxiliary temperature control module: Use mechanical stirring to stir the molten pool multiple times to accelerate the desiliconization reaction and shorten the refining time. When stirring takes away heat, the heating element will fine-tune the power in time to maintain temperature stability and ensure that the reaction proceeds at the optimal temperature.

[0041] Specifically, first, after the furnace body 1 is heated to the appropriate temperature by the heating component, the temperature is detected and controlled by the sensor. High-precision temperature sensors are evenly distributed inside the furnace body, which can collect temperature data of various areas in the furnace in real time and transmit these data to the intelligent control system in a fast transmission manner, laying a solid information foundation for subsequent precise temperature control. Secondly, the distance between the electrode end and the furnace bottom is accurately determined according to the electrode diameter, and it is maintained at about 0.9 times the length of the electrode diameter. The electrode insertion depth is flexibly adjusted in real time according to multiple factors such as the material surface height, so as to reasonably control the amount of coke added and ensure that the temperature distribution in the furnace is scientific and reasonable. In the electrode pressing and releasing operation, the standard instructions are strictly followed. The operator presses and releases the electrode every day, and the pressing degree is accurately controlled at about 20mm and no more than 30mm. In addition, it is strictly prohibited to perform electrode pressing and releasing operations 30 minutes before and when the furnace is taken out of the furnace, so as to ensure temperature stability during the production process. Then, in order to improve the smelting effect, in production scenarios such as high-carbon manganese iron smelting, a higher secondary voltage is selected to effectively The power input to the furnace is increased, and at the same time, advanced electrode position monitoring technology is used to stably control the electrode working section at around 1.7m. The three-phase electrodes are kept balanced and deeply inserted into the furnace to ensure that the furnace reaches an appropriate temperature state. In addition, in close combination with the peak and valley periods of electricity prices, a peak-avoidance production strategy is adopted to intelligently adjust the furnace load and input voltage level to effectively reduce energy consumption and production costs. Furthermore, the intelligent control system pre-sets the optimal temperature curve based on scientific process requirements, compares and analyzes the real-time collected temperature data with it, and then automatically and accurately adjusts the power of the heating element to strictly control temperature fluctuations within the preset range. Finally, a mechanical stirring device is used to perform multiple stirring operations on the molten pool to accelerate the desiliconization reaction process and significantly shorten the refining time. During the stirring process, once it is detected that heat is being taken away, the heating element immediately responds by fine-tuning the power to continuously maintain temperature stability, ensuring that the entire refining process is always at the optimal temperature state, effectively ensuring the uniform chemical composition of the alloy, avoiding the generation of impurities such as oxides, and greatly improving the purity and quality of the alloy.

The outer side of the arc-shaped plate 510 contacts the inner wall of the furnace body 1. The arc-shaped plate 510 regularly scrapes off the ore slag on the inner wall of the furnace body 1 to prevent it from accumulating on the furnace wall and affecting the heat transfer efficiency, ensuring that the furnace body 1 is heated evenly, which is conducive to maintaining a stable reaction temperature in the furnace.

[0044] The mixing structure 6 includes a sun gear 67 arranged on the outside of the rotating rod 4, and the mixing structure 6 also includes a ring gear 68 arranged inside the furnace body 1. A planetary gear 66 is meshed and connected between the ring gear 68 and the sun gear 67. A stirring blade 65 is provided on one side of the planetary gear 66. The outer side of the ring gear 68 is rotatably connected to a disc shell 61, and the disc shell 61 is fixedly connected to the inner wall of the furnace body 1.

The top of the rotating column 64 It is connected to the three-connector plate 63, the rotating column 64 is connected to the stirring blade 65, and there are three groups of planetary gears 66 distributed at equal intervals. The number of rotating columns 64 and stirring blades 65 is equal to the number of planetary gears 66. The outer side of the rotating rod 4 is also rotatably connected to the circular plate 62. A groove 69 is opened between the circular plate 62 and the disc shell 61. The three groups of rotating columns 64 slide in the groove 69, so that the stirring blade 65 can realize complex revolution and rotation motion, which can more fully mix the ore and molten metal in the furnace, making the reaction more uniform and thorough.

[0045] The interior of the furnace body 1 is also rotatably connected to a turning and stirring structure 7, which is used to turn and stir the materials. The turning and stirring structure 7 includes a connecting ring 72 rotatably connected to the outside of the rotating rod 4, and a turning plate 74 is rotatably connected to the outside of the connecting ring 72.

The flipping and stirring structure 7 can continuously flip the material in the furnace, so that the material is heated more evenly in the furnace, avoiding local overheating or underheating, and helping to improve energy utilization efficiency.

[0046] Specifically, the ore to be refined is transported to the inside of the feed frames 2 on both sides of the furnace body 1 by the feed conveyor device, so that the ore inside the feed frames 2 enters the interior of the furnace body 1. This design of the double-sided feed frames 2 can realize continuous feeding, which greatly improves the feeding efficiency and shortens the production cycle compared to single-sided feeding, thereby increasing the overall refining output.

[0047] When the servo motor 3 is turned on and driven, the servo motor 3 drives the rotating rod 4 to rotate, and the rotating rod 4 extends to the inside of the furnace body 1, and then the servo motor 3 drives the rotating rod 4 to rotate, and the rotating rod 4 drives the worm 52 on the surface to engage and rotate with the worm gear 53.
