The rotary joint of the converter series is a fluid medium transition connection sealing device designed specifically for steelmaking converters, which plays a crucial role in the steelmaking process. The following is a detailed analysis of the rotary joints in the converter series:
Converter rotary joint is a transitional sealing device that can input fluid medium from a static system to a dynamic rotating system. According to the different ear axis regions, it can be divided into driving end rotating joints and passive end rotating joints; According to the type of fluid medium being transmitted, it can be divided into water-cooled rotary joints and cyclone adapters.
1) Cooling function: The water-cooled rotary joint is mainly used to cool key parts such as the furnace cap, furnace mouth, support ring, and ear shaft, ensuring the stable operation of the converter in high temperature environments.
2) Protective function: Pneumatic rotary joints mainly transmit inert gases such as argon and nitrogen to protect the bottom of the converter, prevent the oxidation of molten steel at high temperatures, and also help improve the purity and quality of molten steel.
1) Wear resistance: During the use of the converter rotary joint, the internal bearings need to continuously rotate, so there are extremely high requirements for the wear resistance of the bearings and housing. High quality rotary joints are made of materials with strong wear resistance to ensure the long-lasting operation of the equipment.
2) Corrosion resistance: As the rotary joint not only needs to be connected to the equipment that transports the medium, but also needs to transport the medium itself, it must have high-strength corrosion resistance. This ensures that the rotary joint will not leak due to medium corrosion when transmitting highly corrosive media.
3) Sealing performance: The sealing performance of a rotary joint is one of its most critical features. Seals and sealing rings made of special materials can maintain good sealing effect and reduce medium leakage during long-term use.
The rotary joint of the converter is connected to the flanges at both ends through a turntable, and the connection and transfer of liquid between different pipelines are achieved by rotating the turntable. The device rotates according to the different flow directions of the liquid, ensuring smooth fluid flow and avoiding the generation of circular stress and vibration in the pipeline. The sealing between the turntable and the flange is strictly guaranteed, and sealing elements such as graphite rings or O-rings are usually used to achieve no leakage.
Converter rotary joints are widely used in industrial fields such as steel smelting, petroleum, and chemical engineering. In the process of steel smelting, it is not only an important component of the converter equipment, but also directly affects the efficiency and product quality of the steelmaking process.
In order to maintain the good performance and extend the service life of the converter rotary joint, regular maintenance and upkeep are necessary. Specific measures include:
1) Regular inspection: Check the sealing performance, wear condition, and whether the fasteners of the rotary joint are loose.
2) Cleaning and maintenance: Keep the rotary joint and its surrounding environment clean, avoiding impurities and dirt from entering the interior and causing wear and blockage.
3) Lubrication and oil injection: For rotary joints with oil injection devices, regular oil injection should be carried out to ensure the smooth operation of the bearings.
4) Avoid idling: Long term idling may lead to increased internal wear of the rotating joint, and this situation should be avoided as much as possible.
In summary, the rotary joint of the converter series is an indispensable and important component of steelmaking converter equipment. Through its efficient cooling, protection, and transmission functions, the converter can ensure stable operation in high temperature, high pressure, and corrosive medium environments, thereby improving the efficiency and product quality of the steelmaking process.
