Special rotary joints for steel mills are key components designed for equipment such as steelmaking converters. They are mainly used to transfer cooling fluid media, gaseous media, and pressure media from static systems to dynamic rotary systems, achieving dynamic rotary sealing. The following is a detailed introduction to the specialized rotary joints for steel mills:
Special rotary joints for steel mills usually include drive end rotary joints and floating end rotary joints. The main difference between the two is that they transport different media, but the internal sealing structure principle and installation connection method are the same. The rotary joint shaft is usually installed on the converter ear shaft in a flange connection, and the ear shaft is equipped with an inner tube inserted into the rotary joint shaft of the converter to transport the corresponding medium.
a. Function: The specialized rotary joint for steel mills can simultaneously transport cooling water, gas, hydraulic oil and other media, providing cooling water for the converter mouth, furnace cap and sliding plate slag blocking device, gas source for the converter bottom blowing system, and hydraulic oil for the converter sliding plate slag blocking device. It is a key component equipment of the steelmaking converter, which is related to the accuracy and service life of the converter's key functions.
b. Application: Special rotary joints for steel mills are widely used in equipment such as steelmaking converters, continuous casting machines, and mud cannons in the steel and metallurgical industry, and are an important component of these devices.
a. Selection: When choosing a specialized rotary joint for steel mills, factors such as the temperature, pressure, flow rate of the medium, as well as the speed and displacement of the equipment, need to be considered. At the same time, it is necessary to choose the appropriate joint type and size based on the specific structure and installation space of the equipment.
b. matters needing attention:
Ensure good sealing performance of the rotary joint to avoid medium leakage.
Regularly inspect the wear of rotary joints and replace severely worn components in a timely manner.
When installing and disassembling rotary joints, relevant operating procedures should be followed to avoid damaging the joints and seals.
In order to ensure the long-term stable operation of the steel mill's dedicated rotary joint, regular maintenance and upkeep are required. Specific measures include:
a. Regularly clean the dirt and debris on the surface of the rotary joint to maintain its cleanliness.
b. Regularly inspect the wear of sealing components and bearings of rotary joints, and replace them promptly if there are any abnormalities.
c. Regularly check whether the connecting bolts and flanges of the rotary joint are loose or damaged. If there are any abnormalities, they should be tightened or replaced in a timely manner.
d. When not in use for a long time, the rotary joint should be cleaned and lubricated to extend its service life.
With the continuous development of steel metallurgy technology, the requirements for specialized rotary joints in steel mills are also constantly increasing. In the future, specialized rotary joints for steel mills will develop towards higher pressure, higher temperature, and greater displacement, while also requiring better wear resistance, corrosion resistance, and sealing performance. In addition, with the continuous advancement of intelligence and automation technology, the specialized rotary joints for steel mills will gradually realize functions such as remote monitoring and intelligent diagnosis.
In summary, the specialized rotary joint for steel mills is one of the important components and equipment in the steel metallurgy industry. In the process of selection, use, and maintenance, multiple factors need to be comprehensively considered to ensure that it can meet the specific application requirements and operate stably in the long term.
