Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel rolling auxiliary equipment technology, and in particular to a device for handling the derailment of a walking beam steel rolling heating furnace. Background Technology
[0002] In the production of steel billets in walking beam rolling mills, the billets are propelled forward by the rectangular motion of the walking beam. To ensure accurate positioning, laser detectors are typically installed near the discharge furnace door to detect whether the billets have reached the preset position. However, due to malfunctions in the laser detector or other reasons, the billets may not be detected at the furnace head, leading to frequent incidents of thin billets derailing at the furnace head. This can cause the furnace to be unable to discharge steel and resume production, resulting in the shutdown of the entire rolling line. Handling derailed thin billets involves high ambient temperatures and long processing times. Thin billets generate significant resistance during production, making the process time-consuming, labor-intensive, and posing safety hazards. Therefore, this paper presents a device for handling derailments in walking beam rolling mills. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example 1, referring to Figure 1-4A device for handling derailment of a walking beam steel rolling furnace includes a clamping plate 1. A tiger-mouth locking part 8 is provided on one side of the bottom of the clamping plate 1. A connecting bolt 11 is inserted into the top of the clamping plate 1. A lifting ring 7 is screwed onto the connecting bolt 11. An adjustment mechanism is connected to the two lifting rings 7.
[0021] The adjusting mechanism includes a lifting plate 2, on which a strip hole 3 is provided. A bidirectional screw 5 is rotatably installed at the strip hole 3 via a bearing. Both ends of the bidirectional screw 5 are screwed with I-beam sliders 6. One end of the bidirectional screw 5 extends to the outside of the lifting plate 2 and is connected to a handwheel 9.
[0022] Both I-shaped sliders 6 are slidably engaged at the strip hole 3, and the two I-shaped sliders 6 are symmetrically distributed on the clamping plate 1.
[0023] The lower ends of the two I-shaped sliders 6 are each equipped with a first connecting ring 13, and each of the two first connecting rings 13 is connected to an O-ring 12. The two O-rings 12 are respectively fitted onto the two lifting rings 7.
[0024] By rotating the double-acting screw 5 with the handwheel 9, the double-acting screw 5 can drive the two I-shaped sliders 6 to slide along the strip hole 3, which makes it easy to adjust the distance between the two I-shaped sliders 6. This allows the distance between the two clamping plates 1 to be adjusted according to the width of the steel billet. The two clamping plates 1 can then be engaged with their snap-fit parts 8 on both sides of the steel billet.
[0025] Example 2 is an optimization based on Example 1, specifically:
[0026] U-shaped rods 4 are rotatably installed on the middle of both sides of the lifting plate 2 via connecting pins. A second connecting ring 10 is fixed to the middle of the upper surface of the horizontal section of the U-shaped rod 4. The second connecting ring 10 is externally connected to one end of the wire rope of the crane.
[0027] When the high-temperature steel billet falls below the furnace head and furnace door, the heating furnace stops tapping steel, the furnace pressure is adjusted to negative pressure, the heating operator cuts off the power to the roller conveyor, and the high-temperature steel billet is cooled down. The heating furnace operator moves the overhead crane below the furnace head and furnace door, and inserts the two clamping plates 1 into the two sides of the fallen steel billet. The overhead crane is used to gradually lift the billet. During the hoisting process, the position of the steel billet is adjusted by the tapping machine to prevent the fallen steel billet from getting caught on the furnace door structure and refractory materials. As the overhead crane rises, the fallen steel billet will be further clamped by the clamping plates 1. Then the fallen steel billet is pulled out of the material end gap, which can realize the rapid resumption of production of the rolling line.
[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
