The converter support ring is an essential component in converter operation, and its installation quality is directly related to the normal operation and operational safety of the converter. Below, I will provide a detailed introduction to the installation precautions for the converter support ring.

Firstly, selecting the appropriate support ring is crucial. The material, size, and structure of the support ring should be selected based on the specific situation and design requirements of the converter. Generally speaking, the support ring should be made of high-strength, heat-resistant, and wear-resistant materials, such as high-temperature alloy steel or cast refractory materials. In addition, the size and structure of the support ring also need to strictly comply with the design requirements to ensure its stability and reliability.

Secondly, before installing the support ring, it is necessary to inspect it to ensure that there are no damages or other defects. Especially, it is necessary to carefully inspect whether the weld seam of the support ring is firm and whether there are cracks. Only by ensuring the quality of the support ring is qualified can installation proceed.

When installing the support ring, it is necessary to pay attention to the following points:

Bottom ring installation: The bottom ring is the main supporting part of the support ring, and its installation quality directly determines the stability of the support ring. Before installing the bottom ring, it is necessary to check for any damage or cracks. Then, place the bottom ring into the groove at the bottom of the converter and secure it with welding or bolts. During installation, ensure that the bottom ring is in close contact with the groove at the bottom of the converter and is firmly welded or fixed.

Support wing installation: The support wing is the connecting part between the bottom ring and the furnace body, and its main function is to transfer the load of the support ring. When installing the support wing, it is necessary to ensure that the connection between the support wing and the bottom ring is firm, and non-destructive testing should be carried out at the welding point to ensure safety.

Installation of support ring body: When installing the support ring body, it is necessary to ensure that it is firmly connected to the bottom ring and support wing. In general, the support ring body is connected to the support wing through bolts. The selection of bolts should meet the design requirements, and ensure that the tightening force of the bolts is appropriate during installation, but they should not be too loose.

Symmetry and balance: When installing the support ring, it is necessary to ensure its symmetry and balance. The support ring should be correctly equipped with symmetrical components, and the balance of the support ring should be ensured through adjustment, inspection, and calibration during the installation process. Only by ensuring the symmetry and balance of the support ring can problems such as uneven loads and stress concentration be avoided.

Safety protection: When installing the support ring, it is necessary to strictly follow the relevant safety operating procedures, use specialized safety tools, and wear personal protective equipment. Special attention should be paid to avoiding the fall of support rings or other components to prevent personal injury.

In summary, the installation of converter support rings requires special caution and must be operated according to specific circumstances and regulatory requirements. Only by ensuring the quality and installation quality of the support ring are qualified can the safe and normal operation of the converter be guaranteed.
