AI Technical Summary
The traditional guide tube is fixed on the ladle cover, which makes the guide tube easy to be damaged and difficult to feed the wire through the slag layer, affecting the wire feeding efficiency and increasing production costs.
A refining furnace wire feeding guide device including a fixed frame, a wire guide device and an adjustment device was designed. The movable guide tube was flexibly raised and lowered by a lifting cylinder and a traction rope to avoid damage from high temperature or slag. The wire tension and height were adjusted in combination with the adjustment cylinder.
Flexible adjustment of the catheter and precise wire feeding are achieved, which prolongs the service life of the catheter and reduces production costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical production equipment, and in particular to a wire feeding guide device for a refining furnace. Background Technology
[0002] In the steel metallurgical production process, a small amount of other metal wires needs to be fed into the ladle during the melting of metal materials to improve the quality of the finished steel product. Traditionally, a guide tube is fixedly installed on the ladle cover, through which the wire is threaded and fed into the molten steel. However, because the guide tube is fixed to the ladle cover for a long time, the part of the guide tube extending into the ladle cover is damaged by high temperature or steel slag, resulting in insufficient guide tube length. This makes it difficult for the wire to pass through the steel slag layer and be fed into the molten steel, which is not conducive to simple and efficient wire feeding. At the same time, the frequent damage to the guide tube requires frequent repair, which is not conducive to saving production costs. Therefore, improvements are still needed. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a wire feeding guide device for a refining furnace, comprising a fixed frame, on which a wire guiding device and an adjusting device are mounted. The wire guiding device is installed behind the adjusting device. The wire guiding device includes a lifting cylinder, a traction rope, and a fixed guide tube. The lifting cylinder is mounted on the fixed frame, and a telescopic rod is provided at the upper end of the lifting cylinder. The fixed guide tube is obliquely fixed on the fixed frame, and a movable guide tube is sleeved at the front end of the fixed guide tube. One end of the traction rope is connected to the telescopic rod, and the other end is connected to the movable guide tube.
[0004] Preferably, the guide wire device includes a fixed frame, which is mounted on a fixed bracket. Multiple pressure rollers are arranged side by side on the fixed frame. An adjusting guide is provided at the front end of the fixed frame. An adjusting cylinder is provided below the adjusting guide. The adjusting cylinder is obliquely mounted at the front end of the fixed frame. A push rod is provided at the front end of the adjusting cylinder. The front end of the push rod is connected to the adjusting guide.
[0005] Preferably, the upper end of the fixing frame is provided with a plurality of traction pulleys, which are used to pull the traction rope.
[0006] Preferably, a steel ladle is installed on the fixing frame, and a furnace cover is provided on the upper end of the steel ladle, with a guide tube opening on the furnace cover.

Detailed Implementation
[0014] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.
[0015] Unless otherwise stated, any feature in this specification may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is merely one example of a series of equivalent or similar features.
[0016] like Figure 1 , 3 The illustrated refining furnace wire feeding guide device includes a fixed frame 1, on which a wire guiding device 3 and an adjusting device 2 are mounted. The wire guiding device 3 is installed behind the adjusting device 2. The wire guiding device 3 includes a lifting cylinder 13, a traction rope 16, and a fixed guide tube 15. The lifting cylinder 13 is mounted on the fixed frame 1, and a telescopic rod 14 is provided at the upper end of the lifting cylinder 13. The fixed guide tube 15 is obliquely fixed on the fixed frame 1, and a movable guide tube 18 is sleeved at the front end of the fixed guide tube 15. One end of the traction rope 16 is connected to the telescopic rod 14, and the other end is connected to the movable guide tube 18.
[0017] The upper end of the fixed frame 1 is provided with a plurality of traction pulleys 17, which are used to pull the traction rope 16.
[0018] like Figure 2 As shown, the wire guide device 3 includes a fixed frame 6, which is mounted on a fixed frame 1. Multiple pressure rollers 7 are arranged side by side on the fixed frame 6. An adjusting guide tube 8 is provided at the front end of the fixed frame 6. An adjusting cylinder 10 is provided below the adjusting guide tube 8. The adjusting cylinder 10 is obliquely mounted at the front end of the fixed frame 6. A push rod 9 is provided at the front end of the adjusting cylinder 10. The front end of the push rod 9 is connected to the adjusting guide tube 8.
[0019] A steel ladle 5 is installed on the fixed frame 1. A furnace cover is provided on the upper end of the steel ladle 5, and a guide tube opening is provided on the furnace cover.
[0020] An L-shaped bracket 11 is provided behind the wire guide device 3. Multiple guide wheels 12 are provided on the L-shaped bracket 11. A wire feed reel 4 is provided below the L-shaped bracket 11. Both the wire feed reel 4 and the L-shaped bracket 11 are mounted on the fixed frame 1.
[0021] During use, when it is necessary to feed wire into the ladle 5, the wire from the wire feeding reel 4 is sequentially pulled through the guide wheel 12 and the pressure wheel 7 and passes through the adjusting guide tube 8. Then, the wire is threaded into the fixed guide tube 15 and into the movable guide tube 18. During this process, the movable guide tube 18 will push the telescopic rod 14 upward through the lifting cylinder 13, so that the traction rope 16 pulls the movable guide tube 18 diagonally downward into the ladle 5, thereby allowing the wire to pass through the movable guide tube 18 and be fed into the ladle 5.
[0022] After the wire is fed in, the telescopic rod 14 is pulled down by the lifting cylinder 13, so that the traction rope 16 pulls the movable guide tube 18 away from the guide tube opening of the ladle, thereby avoiding damage to the guide tube caused by high temperature or steel slag.
[0023] If it is necessary to adjust the tension of the thread or the lifting height of the traction, the adjusting guide tube 8 can be rotated up or down by pulling the adjusting cylinder 10 up or down, thereby adjusting the tension of the thread or the lifting height of the traction.
[0024] The beneficial effects of this utility model are: the structure of this utility model is reasonable and easy to use. By setting up a lifting cylinder, the movable guide tube can be flexibly pulled up or down, which facilitates precise wire feeding into the ladle and avoids damage to the guide tube caused by high temperature or steel slag, thereby improving the service life of the guide tube and saving production costs.
[0025] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
