Description

Technical Field

[0001] The utility model relates to the technical field of converter support rings, and more specifically to a reinforced shielding cover support ring. Background Art

[0002] The converter support ring is an important part of the converter. The support ring is composed of two fan-shaped segments and two trunnion blocks. The fan-shaped segment is a welded structure, and the trunnion block is a forged and welded structure. The fan-shaped segment and the trunnion block are welded into a support ring through four interfaces. The support ring is welded by the inner and outer plates of the upper and lower cover plates. The difficulty in making the support ring is to ensure the coaxiality of the two trunnions, which needs to be achieved through welding technology. In the welding process, the first thing to do is to prevent welding deformation. Due to the shape and size limitations of the support ring, it is impossible to use overall processing to ensure the coaxiality of the two trunnions. It can only be ensured that the coaxiality of the two trunnion blocks after the support ring is welded is less than or equal to 1mm by controlling the welding deformation of the multiple welds of the fan-shaped segment and the trunnion block after the two trunnion blocks are finely processed. Secondly, the welding stress must be considered. The support ring has a complex structure, the thickness of the upper and lower cover plates and the web is large, the filling amount of the joint is large, the welding deformation law is difficult to determine, and the overall stress relief treatment cannot be performed after the support ring is welded. Therefore, when welding the support ring and the trunnion block, the key to manufacturing the support ring is to effectively reduce the welding stress and control the welding deformation by formulating a reasonable welding process. At present, the structure of the trunnion block in the support ring is a box-type mechanism. The production of the trunnion block requires the trunnion to be integrally welded with the inner and outer plates, the upper and lower covers, and the reinforcing rib plate in the box. The traditional manufacturing process is to assemble the trunnion with the inner and outer plates, the upper and lower covers, and the tie bars in the cavity as a whole after rough machining of the trunnion, and then weld it as a whole. First, the trunnion is transferred from the forging workshop to the processing workshop for rough machining, and then to the welding workshop. After the welding workshop is completed, it is transferred to the heat treatment workshop. After the heat treatment work is completed, it is transferred back to the processing workshop. After the processing workshop is completed, it needs to be transferred back to the welding workshop for the overall trial assembly of the support ring. The process is very long, the number of transfers is very large, and a lot of time and cost are wasted. With the development of production, the current production plan is far from meeting the needs of the market. It is very necessary to change the current traditional manufacturing process and adopt new processes and methods to make the support ring.

[0003] In the prior art, a patent document with publication number CN206052071U provides a converter support ring device, which fixes the converter through a U-shaped support ring body in conjunction with a connecting device, and then rotates the converter through a rotating rod in conjunction with a rotating shaft and a motor.

[0004] Although the converter support ring device has many beneficial effects, it still has the following problems: the converter support ring device is composed of an external support ring that cooperates with multiple connecting frames to fix the internal converter, and the support ring is not provided with a heat insulation device, which will cause the temperature of the support ring to rise quickly and the heat insulation effect is poor, which needs to be improved; secondly, the U-shaped support ring body of the converter support ring device cooperates with multiple connecting frames to fix the converter, and the fixing frame directly contacts the converter, which is easy to cause the fixing frame to break in the long term, causing safety accidents, and the safety needs to be improved. Therefore, in view of the above problems, a reinforced shielding cover support ring is proposed. Utility Model Content
