Description

Technical Field

[0001] The utility model relates to the field of cooling water pipe connection design, in particular to a flexible device that solves the problem that the cooling water pipe of a converter body is easily cut. Background Art

[0002] The traditional converter body cooling water pipe is composed of a hard pipe or a hard pipe plus a metal hose. For the furnace body support device with a ball hinge structure, only radial displacement along the ear axis direction occurs when the converter tilts. For the five-link hanging support device, multi-directional displacement occurs when the converter tilts. However, whether it is a ball hinge or a five-link hanging support device, the furnace body and the support ring will produce a slight relative displacement when the converter tilts. If there is an abnormality in the furnace body support device, such as a gap in the furnace body stop block of the ball hinge structure, damage to the bearing of the five-link hanging structure, cracking of the weld, etc., it will cause a large relative displacement between the furnace body and the support ring, and eventually cause the furnace body cooling water pipe to be damaged by shear force and leak, and the furnace is forced to be shut down for treatment, which seriously restricts the normal production of the converter. Utility Model Content

[0003] The technical problem to be solved by the utility model is that there is a gap in the furnace body stop block of the ball hinge structure, and damage to the bearings of the five-link suspension structure and cracking of the welds will cause a large relative displacement between the furnace body and the support ring, which will eventually cause the furnace body cooling water pipe to be damaged by shear force and leak, forcing the furnace to be shut down for treatment, seriously restricting the normal production of the converter.

[0004] In order to solve the above problems, the technical solution adopted by the present invention is as follows: The present invention is a flexible device for solving the problem that the cooling water pipe of the converter body is easily cut, comprising a first standard flange, a first sphere, a first section of stainless steel pipe, a second sphere, a second section of stainless steel pipe, a third sphere and a second standard flange. The first standard flange is installed on the external structure, the first sphere is connected to the first standard flange, the first section of stainless steel pipe is connected to the first sphere, the second sphere is connected to the first section of stainless steel pipe, the second section of stainless steel pipe is connected to the second sphere, the third sphere is connected to the second section of stainless steel pipe, the second standard flange is connected to the third sphere, and the second standard flange is installed on the external structure.

[0005] Furthermore, the first standard flange and the second standard flange are respectively matched and installed with the welding flanges of the furnace body water hard pipe and connected by bolts.

[0006] Preferably, the telescopic compensation amount of this design is 60 mm.

[0007] Preferably, the present design has an angle compensation of ±10 degrees.

[0008] The beneficial effects achieved by the present invention using the above-mentioned structure are as follows: The innovative and practical flexible device can effectively eliminate the risk of damage to the furnace cooling water pipe caused by shear force generated by slight relative displacement between the furnace body and the support ring. Specifically, a flexible device with a spherical arc structure is installed at an appropriate position on the furnace cooling water pipe. This spherical flexible device can be reasonably designed based on the on-site spatial layout, stress conditions, etc. The spherical arc surface is designed to absorb the misalignment caused by the relative displacement between the furnace body and the support ring. This misalignment is absorbed, compensated, and eliminated by the spherical arc, which can effectively eliminate the risk of shearing of the cooling water pipe. The design also has a flange structure that allows for convenient and quick installation with on-site cooling water hard pipes.

[0009] Significant advantages:

[0010] 1. It can greatly save the time of repairing cooling water pipe welding and reduce labor intensity;

[0011] 2. It can greatly reduce the frequency of shearing of the furnace cooling water pipe due to the shear force generated by the displacement of the furnace body and the support ring, and can even achieve no shearing;

[0012] 3. Easy and quick installation;

[0013] 4. Maintenance-free;

[0014] 5. Improve production rhythm and reduce production costs;

[0015] 66. Applicable to the popularization and promotion of similar equipment in the steel industry. BRIEF DESCRIPTION OF THE DRAWINGS
