Description

Technical Field

[0001] This utility model belongs to the technical field of electric arc furnaces and accessories, and in particular relates to a pressure ring bottom liner plate that prevents burn-through. Background Technology

[0002] Pressure rings are a key component used in high-voltage electrical equipment or mechanical sealing systems. They are mainly used to distribute pressure evenly, prevent partial discharge or breakdown, and may also serve functions such as insulation, sealing or mechanical support. They are an important part of electric arc furnaces.

[0003] Existing pressure rings used in electric arc furnaces operate in a high-voltage environment, making them susceptible to breakdown by high-voltage arcs during opening and closing. Since the pressure ring uses water circulation for heat dissipation, water leakage occurs after breakdown, and water droplets contacting the high-voltage arc can easily cause an explosion. Therefore, to prevent the pressure ring from being broken down during opening and closing, a protective liner is usually welded to the bottom of the pressure ring. This liner grounds the pressure ring, effectively preventing arc breakdown. However, existing protective liners are directly welded to the pressure ring, meaning that if either the pressure ring or the liner is damaged, both need to be replaced simultaneously, resulting in high maintenance costs. Furthermore, the fixed dimensions of the protective liner limit its applicability and practicality.

[0004] To address these issues, we provide a pressure ring backing plate that prevents burn-through. Utility Model Content

[0005] The purpose of this utility model is to provide a pressure ring bottom liner that prevents burn-through. The pressure ring body and the mounting block are connected by the mounting post on the movable plate, and the mounting plate is fixed on the pressure ring body. This solves the problem of inconvenient installation and disassembly of the liner in the existing system. At the same time, the movable liner moves relative to the fixed liner through the second threaded rod, and the total area of ​​the liner is adjusted, which solves the problem of the limited applicability of the existing system.
