Description

Technical Field

[0001] This utility model relates to the technical field of deoxidation wire feeding devices, and in particular to a deoxidation wire feeding device for an LF ladle refining furnace. Background Technology

[0002] The LF ladle refining furnace is a key secondary refining equipment in steelmaking, primarily used for steel temperature regulation, composition fine-tuning, and deoxidation and desulfurization. In the LF furnace refining process, deoxidation wire feeding is a crucial step in improving the purity of the molten steel. It effectively reduces oxygen content and non-metallic inclusions by precisely feeding deoxidizers such as aluminum wire (Al) and silicon-calcium wire (Si-Ca) into the molten steel. However, traditional wire feeding devices are prone to problems such as uneven wire feeding, deoxidation wire misalignment, and even stray wire during operation, affecting deoxidation efficiency and steel quality. Therefore, there is an urgent need for a device that can stably and precisely control the wire feeding process to meet the technological requirements of high-quality steel production.

[0003] Currently, LF furnace deoxidation wire feeding mainly employs a mechanical wire feeding mechanism, whose core structure includes a wire feeding reel, guide wheel assembly, and drive motor. During operation, the motor drives the wire feeding rollers to rotate via gears or belts, drawing the deoxidized wire from the reel and feeding it into the ladle. Some equipment may include tension adjustment devices, such as friction brakes or counterweights, to maintain stable wire feeding tension. Furthermore, existing technologies typically rely on manual observation or simple sensors to monitor the wire feeding status and adjust the feeding speed to prevent wire breakage or accumulation.

[0004] However, traditional wire feeding devices lack a dynamic limit adjustment mechanism during operation. This can cause the deoxidation line to deviate from its predetermined path due to tension fluctuations or mechanical vibrations, reducing deoxidation efficiency and potentially affecting continuous production due to wire entanglement or breakage. This problem is particularly prominent in high-intensity, long-duration wire feeding operations, restricting the stability and reliability of the LF ladle refining process. Therefore, a deoxidation wire feeding device for the LF ladle refining furnace is proposed to solve these problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a deoxidation wire feeding device for an LF ladle refining furnace, which aims to improve the problem in the prior art that the deoxidation wire is prone to deviation or flying wire during high-speed feeding, resulting in uneven wire feeding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deoxidation wire feeding device for an LF ladle refining furnace, comprising a base, a housing slidably connected to the upper surface of the base, a motor fixedly connected to one side of the outer wall of the housing, a transmission shaft fixedly connected to the output end of the motor, a wire output roller fixedly connected to one end of the transmission shaft, a transmission assembly installed on the upper surface of the base, a connecting seat fixedly connected to the upper surface of the base, a threaded sleeve fixedly connected to the bottom of the inner wall of the housing, and an anti-flying wire assembly installed on the upper surface of the housing;

[0007] The anti-flying wire assembly includes a fixed bracket, the lower surface of which is fixedly connected to the upper surface of the housing. A limit frame is slidably connected inside the fixed bracket. A spring is fixedly connected to the lower surface of the limit frame. A limit roller is installed on the lower surface of the spring. An adjusting bolt is rotatably connected to the upper surface of the limit frame.

[0008] Furthermore, the transmission assembly includes a second motor, the lower surface of which is fixedly connected to the upper surface of the base, and a lead screw is fixedly connected to the output end of the second motor. One end of the lead screw is rotatably connected inside the connecting seat, and the lead screw is threadedly connected to a threaded sleeve. The connecting seat penetrates the housing and is slidably connected.

[0009] Furthermore, a symmetrical L-shaped bracket is fixedly connected to one side of the outer wall of the housing, and a rotating rod is rotatably connected between the two L-shaped brackets. The rotating rod is connected to the transmission shaft via a belt drive, and a bidirectional threaded groove is provided on one side of the rotating rod.

[0010] Furthermore, a slider is slidably connected to the outer wall of the L-shaped bracket, and the slider is threadedly connected to a bidirectional threaded groove.

[0011] Furthermore, a support frame is fixedly connected to one side of the outer wall of the slider, and a limit wheel is rotatably connected to the lower side inside the support frame.

[0012] Furthermore, a second slider is slidably connected to the inner wall of the support frame, and a second limit wheel is rotatably connected to one side of the outer wall of the second slider.

[0013] Furthermore, a second spring is fixedly connected to the upper surface of the second slider, and a sliding plate is fixedly connected to the upper end of the second spring.

[0014] Furthermore, an adjusting bolt two is rotatably connected to the upper surface of the sliding plate, the outer wall of the adjusting bolt two is rotatably connected to the inside of the support frame, and the outer wall of the sliding plate is slidably connected to the inner wall of the support frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the motor drives the transmission shaft to rotate the output roller, thereby facilitating the uniform feeding of the deoxidation line to the LF ladle refining furnace. By rotating the adjusting bolt, the limiting frame slides to limit the movement, while the limiting roller abuts against the outer wall of the deoxidation line inside the output roller. At the same time, the extension and retraction of the spring ensures that the deoxidation line abuts against the deoxidation line according to its usage, preventing the deoxidation line from flying off, thus improving the practicality of the device.

[0017] 2. In this utility model, the rotation of the transmission shaft facilitates the rotation of the internal rotating rod of the belt. The rotation of the bidirectional threaded groove and the slider 1 causes the slider 1 to slide back and forth on the outer wall of the rotating rod. The movement of the support frame then places the deoxidized wire between the limiting wheel 1 and the limiting wheel 2 for controlled feeding. Simultaneously, rotating the adjusting bolt 2 causes the sliding plate to push and compress the spring 2, thus adjusting the limiting wheel 2 on the outer side of the slider 2 according to the thickness of the deoxidized wire, thereby improving the practicality of the device.
