Description

Technical Field

[0001] This utility model relates to the field of intelligent control technology for wire feeders, and more specifically, to an intelligent and precise control device for a casting wire feeder. Background Technology

[0002] A wire feeder is a device used to inject alloy core wire into molten steel at an appropriate speed and in a set quantity, causing it to disperse evenly and achieving purposes such as deoxidation, altering inclusion morphology, and fine-tuning composition. Using a wire feeder for desulfurization, spheroidization, and inoculation treatments eliminates interference from human factors, resulting in good reproducibility. It can maintain the residual magnesium content of the treated molten iron within a very small fluctuation range of the same order of magnitude, thus ensuring stable product quality.

[0003] As is well known, adding alloy core wire online during the casting process is one of the most effective measures to refine the grain structure of the ingot. Currently, slippage and breakage of the wire are prone to occur during production. This is because the gap between the drive roller and the driven roller is too tight, the transmission speed is too fast, causing the wire to break, or the gap is too large, causing the wire to slip. The spacing and speed of the drive roller cannot be adjusted according to the thickness of the alloy core wire, thus affecting the quality of the final product. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0021] See attached document Figure 1 , Figure 2 As shown, an intelligent precision control device for a casting wire feeder includes an intelligent control unit and a feeding device. The intelligent control unit is connected to the feeding unit and controls the feeding device to precisely deliver alloy core wire. The intelligent control unit includes a controller 1, which is connected to a speed measuring unit 2, a testing unit 3, a wire cutting device 4, and an alarm 5. The speed measuring unit 2 and the testing unit 3 are respectively connected to the input interface of the controller 1. The wire spool is mounted on a turntable 15. The speed measuring unit 2 is a speed sensor mounted on the wire spool. The alloy core wire wound on the wire spool is fed into the wire roller assembly through a wire guide tube 10.

[0022] The feeding device includes a speed control device 7 connected to the controller 1, which is connected to a power unit 8. The power unit 8 is connected to the guide roller assembly 11 via a frequency converter 9. The speed control device 7 is a motor driver. The power unit 8 is a variable frequency motor, which is connected to the motor driver. The variable frequency motor is connected to the guide roller assembly 11 via a frequency converter. The upper and lower rollers of the guide roller assembly are connected to the output shaft of the frequency converter via upper and lower drive shafts, respectively.

[0023] The testing unit 3 takes samples every ten minutes to measure the content of trace elements in the molten steel and transmits the data to the controller 1. Based on the feedback from the testing unit 3, the controller 1 controls the feeding device to quantitatively deliver the alloy core wire. The speed sensor is a photosensitive sensor. The speed measuring unit measures the rotation speed of the wire spool to determine the feeding speed of the alloy core wire. The feeding speed of the alloy core wire also reflects the rotation speed of the guide roller group 11 driven by the variable frequency motor. The speed sensor sends the rotation speed of the wire spool to the controller 1 for analysis. If the speed of the wire spool is higher than the set value, the alarm sounds, and at the same time, the controller 1 controls the motor driver to slow down the speed of the variable frequency motor, thereby slowing down the wire feeding speed of the guide roller group 11.

[0024] A cylinder is mounted on the upper roll of the guide roller assembly. The cylinder is connected to a solenoid valve, which in turn is connected to controller 1. The cylinder piston rod is fixedly connected to a grooved pressure plate 12. Figure 3As shown, the rotating shaft 13 passes through the axis of the upper roller 14 of the guide roller assembly and is fixed at both ends to the bottom sidewall of the grooved pressure plate 12. The controller 1 controls the cylinder to work, driving the upper roller 14 of the guide roller assembly to press down, so that the upper roller 14, the alloy wire, and the lower roller of the guide roller assembly press against each other to form the alloy wire conveying area; this solves the major technical problem that the gap between the upper roller 14 and the lower roller of the guide roller assembly is too tight, resulting in excessive transmission speed and wire breakage, or the gap is too large, causing wire slippage, and the inability to adjust the spacing and speed of the transmission rollers according to the thickness of the alloy core wire, thus affecting the quality of the final product.

[0025] An infrared measuring device is installed at the output end of the guide roller group 11 to measure the length of the output alloy core wire. The infrared measuring device is connected to the controller 1. The infrared measuring device measures the length of the alloy core wire conveyed from the guide roller group 11 and transmits it to the controller 1. After analysis by the controller 1, if the length of the output alloy core wire reaches the preset value, the controller will start the wire cutting device 4 to cut the alloy core wire. At the same time, the length of the fed alloy core wire is recorded so as to accurately control the amount of alloy core wire fed in.

[0026] This invention not only solves the problems of wire slippage and breakage that frequently occur in the operation of wire feeders in the prior art, but also achieves precise control of the amount of alloy core wire fed in, and improves work efficiency. This invention is simple to operate, does not require too many staff members, reduces labor usage, and further enhances the economic benefits for enterprises.

[0027] This invention installs an infrared measuring device at the output end of the guide roller assembly. The infrared light is used to accurately measure the length of the output alloy core wire, and to accurately measure the alloy core wire immersed deep into the molten steel. At the same time, the use of the analysis unit further measures the content of trace elements deep in the molten steel. The combined use of the two devices further keeps the residual magnesium content of the treated molten iron within a very small fluctuation range of the same order of magnitude, thereby stabilizing the product quality.
