Description

Technical Field

[0001] The invention relates to the field of aluminum rod refining technology, in particular to an aluminum rod continuous casting and rolling refining technology and device. Background Art

[0002] Electrical aluminum rods are the basic conductor materials of the power industry. The quality of the rods directly affects the performance of the final aluminum-based enameled wires, and also has a decisive impact on the downstream processing and production processes. For example, the stability and production efficiency of the aluminum wire drawing and enameling processes depend to a large extent on the quality of the rods. Most electrical aluminum rods are produced and processed using continuous casting and rolling technology, which is the source process in the entire aluminum-based enameled wire production chain. Its main production function is to process electrical aluminum ingots into round aluminum rods of the required size, thereby meeting the downstream enameled wire production needs.

[0003] The refining stage of aluminum liquid is a key stage in the continuous casting and rolling production process of aluminum rods. The purpose of refining is mainly to remove gas, slag and make its chemical composition uniform, so as to improve the quality of the product; because in the melting process, oxidation, air absorption, slag inclusion, etc. will cause the mechanical and electrical properties of aluminum rods to deteriorate, and the ingredients with different components will have uneven components after melting, so the refining process must be fully stirred to make it uniform; most traditional refining methods use a spray refining device; using nitrogen as a carrier, the refining agent powder is evenly blown into the melt, and sufficient stirring is required during the refining process to ensure the uniformity of the aluminum liquid composition, so that the refining agent and the impurities in the aluminum liquid can fully contact and react, and the impurities are separated from the aluminum liquid;

[0004] In the existing traditional process operation, the operator places the front end of the refining tube connected to the refining tank close to the furnace bottom and wall, and slowly moves in the insulation furnace in a "z" shape according to the set process. The problem with manual operation is that the differences in human operation, position control, and time control all have large fluctuations. Therefore, the final refining effect will inevitably vary greatly, and the performance of the produced aluminum rods will be greatly affected accordingly, making it impossible to ensure the uniformity of the quality of the aluminum rods.

[0005] In view of the above technical problems, this application proposes a solution. Summary of the invention

[0006] The present invention realizes the flexible movement of the refining car on a two-dimensional plane through the horizontal and vertical moving rods in the three-dimensional moving layer and the sliding cooperation with the movable refining car, so that the movement of the refining car is controlled by a program during the production process, and the accuracy and repeatability of the movement are guaranteed, so as to accurately cover the aluminum liquid in different areas and ensure the refining uniformity during the aluminum liquid treatment process, while saving labor costs and improving production efficiency, solving the problem that the difference in manual operation in the production of aluminum rods will affect the quality of the aluminum rods and the quality stability of the aluminum rods cannot be guaranteed, and an aluminum rod continuous casting and rolling refining process and device are proposed.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] An aluminum rod continuous casting and rolling refining device comprises a fixed base, a three-dimensional moving layer is fixedly installed above the fixed base, a movable refining vehicle is fixedly installed on the upper surface of the three-dimensional moving layer, and a mounting rod is arranged at one end of the fixed base;

[0009] The mounting rod is protruded toward a section away from the movable refining vehicle, providing a movable space for the movable refining vehicle, a refining pipe is fixedly mounted at the front end of the mounting rod, a feed pipe is connected to the top end of the refining pipe, a suction pump is connected to the end of the feed pipe, and the other end of the suction pump is connected to the tank body for extracting the refining agent;

[0010] The three-dimensional moving layer includes a transverse moving rod and a longitudinal moving rod, wherein the longitudinal moving rod is located above the transverse moving rod and can slide axially on the transverse moving rod, and the movable refining vehicle can slide axially on the longitudinal moving rod;

[0011] The three-dimensional moving layer and the suction pump are controlled by a refining intelligent control system, which includes a program automatic control unit, an operation feedback unit, an activity adjustment unit, an early warning output unit and an operation statistics unit;

[0012] The program automatic control unit is used to obtain a preset operating program and control the three-dimensional moving layer and the suction pump to operate. The operation feedback unit collects the operating results of the three-dimensional moving layer and the suction pump through sensors, and obtains the operating program through the program automatic control unit for comparison to obtain the operation feedback result. The activity adjustment unit obtains the operation feedback result through the operation feedback unit, and adjusts the operation of the three-dimensional moving layer and the suction pump in real time according to the operation feedback result. The early warning output unit judges and outputs the operation feedback result, collects and analyzes the adjustment amplitude of the activity adjustment unit, and outputs the judgment result. The operation statistics unit counts the operation feedback result and the judgment result of the adjustment amplitude, and evaluates the safety of the equipment according to the statistical result.

[0013] As a preferred embodiment of the present invention, the operation result of the three-dimensional moving layer collected by the operation feedback unit includes a moving trajectory of the three-dimensional moving layer. When collecting the moving trajectory, the operation feedback unit also adds time information to the moving trajectory, so as to reflect the position at different times;

[0014] The operation result of the suction pump collected by the operation feedback unit is the raw material flow rate of the suction pump, and the time is recorded when collecting the raw material flow rate, so as to obtain the raw material flow rate corresponding to different moments.

[0015] As a preferred embodiment of the present invention, the activity adjustment unit compares the moving trajectory with the set trajectory and determines the overlap between the moving trajectory and the set trajectory. If the overlap between the moving trajectory and the set trajectory meets the standard, no adjustment is required. If the overlap between the moving trajectory and the set trajectory does not meet the standard, feedback adjustment is performed according to the difference between the moving trajectory and the set trajectory.

[0016] The activity adjustment unit matches the time information on the moving trajectory with the raw material flow rate corresponding to each moment to obtain the raw material distribution trajectory. The activity adjustment unit obtains the preset raw material distribution setting, and compares the raw material distribution trajectory with the raw material distribution setting to obtain the comparison coincidence, and judges the comparison coincidence. According to the comparison coincidence judgment result, a normal release signal or an abnormal release signal is generated, and after the abnormal release signal is generated, the abnormal position is obtained according to the comparison result, and feedback adjustment is generated for the abnormal position.

[0017] As a preferred embodiment of the present invention, the method in which the activity adjustment unit compares the moving trajectory with the set trajectory is:

[0018] The method for the activity adjustment unit to compare the moving trajectory with the set trajectory is as follows: the activity adjustment unit draws an image according to the moving trajectory and the set trajectory, wherein the width of the trajectory is set to an allowable error range, the length of overlap between the images of the moving trajectory and the set trajectory is recorded as a normal length, the length of independence between the images of the moving trajectory and the set trajectory is recorded as an abnormal length, and the proportion of the normal length in the middle length is recorded as the degree of overlap.

[0019] As a preferred embodiment of the present invention, the method in which the activity adjustment unit compares the raw material distribution trajectory with the raw material distribution setting is:

[0020] The difference between the raw material flow rate at each position on the moving trajectory and the raw material flow rate at each position on the moving trajectory in the raw material distribution setting is calculated to obtain the flow difference, and the flow difference is compared with the set threshold value. If the flow difference is greater than the set threshold value, the corresponding position is determined as an abnormal position. If the flow difference is not greater than the set threshold value, the corresponding position is determined as a normal position. The activity adjustment unit records the proportion of normal positions in all positions as the comparison coincidence.

[0021] As a preferred embodiment of the present invention, after the early warning output unit obtains the adjustment amplitude, the operating adjustment amplitude is compared with the corresponding set adjustment upper limit. If the operating adjustment amplitude is greater than the set adjustment upper limit, an equipment abnormality signal is generated; if the operating adjustment amplitude is not greater than the set adjustment upper limit, a equipment normal signal is generated and the operating adjustment amplitude is displayed at the same time.

[0022] As a preferred embodiment of the present invention, the operation statistics unit compares the number of occurrences of the operation feedback results with the set threshold, determines the operation accuracy of the refining equipment based on the comparison, judges whether the operation accuracy is within the set threshold range, performs average value analysis through the operation adjustment amplitude, determines the adjustment degree of the operation adjustment amplitude, and judges whether the operation adjustment amplitude is within the set threshold range, thereby generating an equipment safety signal or an equipment abnormality signal based on the operation accuracy and the adjustment degree.

[0023] A continuous casting and rolling refining process for aluminum rods comprises the following steps:

[0024] Step 1: Control the operation of the three-dimensional moving layer and the suction pump through the program automatic control unit to improve the control accuracy during the refining process;

[0025] Step 2: By collecting statistics on the operation results of the three-dimensional moving layer and the suction pump, and comparing the operation results with the set standards, the operation accuracy is judged;

[0026] Step 3: When abnormal operation occurs, the operation of the three-dimensional moving layer or the suction pump is corrected through automatic feedback adjustment to ensure the control accuracy of the refining operation;

[0027] Step 4: Conduct statistical analysis on the overall operation of the refining equipment, generate an equipment safety report, and determine the safety of the equipment.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. In the present invention, the flexible movement of the refining car on a two-dimensional plane is achieved through the lateral and longitudinal moving rods in the three-dimensional moving layer and the sliding cooperation with the movable refining car, so that the movement of the refining car is controlled by a program during the production process, and the accuracy and repeatability of the movement are guaranteed, so that the aluminum liquid in different areas is accurately covered, and the refining uniformity in the aluminum liquid treatment process is guaranteed, while saving labor costs and improving production efficiency.

[0030] 2. In the present invention, based on the linkage operation of multiple modules such as program self-control, operation feedback, and activity adjustment, it is possible to collect equipment operation data in real time and compare it with the preset program, dynamically adjust the parameters of the three-dimensional moving layer and the suction pump, ensure the precise matching of the refining agent dosage, equipment movement trajectory and the set control program, and enable managers to understand the equipment operation precision and accuracy more intuitively.

[0031] 3. In the present invention, by performing long-term analysis on the equipment operation data through the operation statistics unit, judgment and alarm are made according to the abnormal adjustment amplitude and the number of abnormal adjustments, so as to evaluate mechanical fatigue, equipment operation errors and potential failure risks, and realize the dual protection of preventive maintenance and equipment safety.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The mounting rod 4 is protruded away from the mobile refining vehicle 1 to provide a movable space for the mobile refining vehicle 1. A refining pipe 5 is fixedly mounted on the front end of the mounting rod 4. A feed pipe 6 is connected to the top of the refining pipe 5. A suction pump 7 is connected to the end of the feed pipe 6.

[0042] The three-dimensional moving layer 3 includes a transverse moving rod and a longitudinal moving rod, wherein the longitudinal moving rod is located above the transverse moving rod and can slide axially on the transverse moving rod. The movable refining car 1 can slide axially on the longitudinal moving rod, thereby realizing the movement of the movable refining car 1, which is convenient for the refining agent to be evenly distributed inside the aluminum liquid.

[0043] Embodiment 2:

[0044] See also Figure 1 - Figure 4 As shown, the three-dimensional moving layer 3 and the suction pump 7 are controlled by the refining intelligent control system, which includes a program automatic control unit, an operation feedback unit, an activity adjustment unit, an early warning output unit and an operation statistics unit;

[0045] The program automatic control unit is used to obtain the preset operation program and control the three-dimensional moving layer 3 and the suction pump 7 to operate;

[0046] The operation feedback unit collects the operation results of the three-dimensional moving layer 3 and the suction pump 7 through sensors. The operation results of the three-dimensional moving layer 3 collected by the operation feedback unit include the movement trajectory of the three-dimensional moving layer 3. When collecting the movement trajectory, the operation feedback unit also adds time information to the movement trajectory, so as to reflect the position at different times;

[0047] The operation result of the suction pump 7 collected by the operation feedback unit is the raw material flow rate of the suction pump 7, and the time is recorded when collecting the raw material flow rate, so as to obtain the raw material flow rate corresponding to different moments. The activity adjustment unit obtains the operation program through the program automatic control unit and compares the data collected by the operation feedback unit to obtain the operation feedback result;

[0048] The activity adjustment unit compares the moving trajectory with the set trajectory and determines the overlap between the moving trajectory and the set trajectory. If the overlap between the moving trajectory and the set trajectory meets the standard, no adjustment is required. If the overlap between the moving trajectory and the set trajectory does not meet the standard, feedback adjustment is performed according to the difference between the moving trajectory and the set trajectory.

[0049] The activity adjustment unit matches the time information on the moving trajectory with the raw material flow rate corresponding to each moment to obtain the raw material distribution trajectory, obtains the preset raw material distribution setting, and compares the raw material distribution trajectory with the raw material distribution setting to obtain the comparison coincidence, judges the comparison coincidence, generates a normal release signal or an abnormal release signal according to the comparison coincidence judgment result, and after generating the abnormal release signal, obtains the abnormal position according to the comparison result, and generates feedback adjustment for the abnormal position;

[0050] The method for the activity adjustment unit to compare the moving track with the set track is as follows: the activity adjustment unit draws an image according to the moving track and the set track, wherein the width of the track is set to the allowable error range, the length of the moving track and the set track images that overlap is recorded as a normal length, the length of the moving track and the set track images that are independent of each other is recorded as an abnormal length, and the proportion of the normal length in the middle length is recorded as the overlap degree;

[0051] The method by which the activity adjustment unit compares the raw material distribution trajectory with the raw material distribution setting is:

[0052] The difference between the raw material flow rate at each position on the moving trajectory and the raw material flow rate at each position on the moving trajectory in the raw material distribution setting is calculated to obtain the flow difference, and the flow difference is compared with the set threshold value. If the flow difference is greater than the set threshold value, the corresponding position is determined as an abnormal position. If the flow difference is not greater than the set threshold value, the corresponding position is determined as a normal position. The activity adjustment unit records the proportion of the normal position in all positions as the comparison coincidence degree;

[0053] The activity adjustment unit obtains the operation feedback result through the operation feedback unit, and adjusts the operation of the three-dimensional moving layer 3 and the suction pump 7 in real time according to the operation feedback result. During the adjustment, the independent positions of the moving trajectory and the set trajectory are adjusted, the actual moving trajectory is brought closer to the set trajectory, and the operation of the suction pump 7 is adjusted so that the raw material flow rate is close to the flow rate in the raw material distribution setting;

[0054] The early warning output unit judges and outputs the operation feedback results, collects and analyzes the adjustment range of the active adjustment unit, and after obtaining the adjustment range, compares the operation adjustment range with the corresponding set adjustment upper limit. If the operation adjustment range is greater than the set adjustment upper limit, an equipment abnormality signal is generated. If the operation adjustment range is not greater than the set adjustment upper limit, a normal equipment signal is generated and the operation adjustment range is displayed at the same time, so as to output the judgment results, which is convenient for management personnel to intuitively understand the difference between the actual operation and the program setting;

[0055] The operation statistics unit collects statistics on the operation feedback results and the judgment results of the adjustment range, and evaluates the equipment safety based on the statistical results. The operation statistics unit compares the number of occurrences of the operation feedback results with the set threshold, determines the operation accuracy of the refining equipment based on the comparison, and judges whether the operation accuracy is within the set threshold range. The average value analysis is performed through the operation adjustment range, and the adjustment degree of the operation adjustment range is determined, and whether the operation adjustment range is within the set threshold range. If the operation accuracy is within the set threshold and the operation adjustment range is also within the set threshold range, an equipment safety signal is generated, otherwise an equipment abnormality signal is generated.

[0058] Step 1: The three-dimensional moving layer 3 and the suction pump 7 are controlled by the program automatic control unit, so as to improve the control accuracy in the refining process through program control, and avoid the difference caused by manual control affecting the uniformity and stability of the quality of the aluminum rod. Specifically, the tensile strength of the aluminum rod produced by program control can be stabilized at 92-93MPa, and the resistivity can be stabilized at 0.02750-0.02755Ω.mm2 / m. Compared with manual control, the appearance of the aluminum rod produced is also significantly improved, and there are no defects such as hemming, misalignment, cracks, deterioration debris, kinks, etc.

[0059] Step 2: By collecting statistics on the operation results of the three-dimensional moving layer 3 and the suction pump 7, and comparing the operation results with the set standards, the operation accuracy is determined;

[0060] Step 3: When an abnormality occurs during operation, the operation of the three-dimensional moving layer 3 or the suction pump 7 is corrected through automatic feedback adjustment to ensure the control accuracy of the refining operation;

[0061] Step 4: Conduct statistical analysis on the overall operation of the refining equipment, generate an equipment safety report, and determine the safety of the equipment.
