Description

Technical Field

[0001] The utility model relates to the technical field of anti-tilting of medium frequency furnaces, in particular to an anti-tilting protective device for medium frequency furnaces. Background Art

[0002] During the smelting process of the medium frequency furnace, since the furnace body needs to be tilted during the steel-out process, and the furnace body needs to be in a horizontal position during the normal smelting process of the medium frequency furnace, a medium frequency furnace tilting device is required to control the tilting of the medium frequency furnace. Therefore, the medium frequency furnace is not directly fixed on the heating platform, and there is a risk of tilting during the working process. The medium frequency furnace contains high-temperature molten iron, so the molten iron splashes when tilting, which poses a greater risk to working equipment and personnel. Therefore, an anti-tilting protection device for the medium frequency furnace is developed.

[0003] Now we search for the Chinese patent for the anti-tilting protection device for the medium frequency furnace, the publication number is CN 218034398 U, which includes a plane placement frame, the plane placement frame includes a placement plate, the two sides of the placement plate are respectively fixedly connected to two extension platforms, one end of each of the extension platforms is respectively fixedly connected to a vertical bracket column, the inner side of the top of each of the vertical bracket columns is respectively rotatably connected to a rotating connection seat, and a rotating hoop is fixedly connected between the two rotating connection seats. The utility model is provided with a rotatable rotating hoop, which is sleeved on the top of the medium frequency furnace to limit the shaking of the medium frequency furnace. When the medium frequency furnace shakes, it will drive the rotating hoop to shake in the opposite direction, so that the inclined side of the medium frequency furnace is close to the inner wall of the rotating hoop, and through the higher height of the rotating hoop, the splashed molten iron is guided back to the medium frequency furnace, so that the high-temperature molten iron will not splash out of the medium frequency furnace, thereby playing a certain role in the surrounding equipment and staff.

[0004] However, it still has the following disadvantages in actual use:

[0005] Once the hydraulic system of the tilting telescopic rod fails during the production process, the active rod cannot be used normally, which will cause the medium frequency furnace to flip over. The vertical support column and rotating hoop will lose their protective effect, causing equipment damage and personal injury.

[0006] Therefore, we provide a medium frequency furnace anti-tilting protection device to solve the above problems. Utility Model Content
