THE IMPROVEMENT OF OXYGEN FLOW IN CONVERTER STEELMAKING PROCESS
Steelmaking is one of the most important and basic industries in industrial production. The steelmaking process is quite complicated, and oxygen blowing is a very important procedure in this process. Oxygen flow plays an important role in major processes such as smelting, decarbonization, desulfurization, and so on. Steelmaking industry constantly improves the performance of oxygen blowing and various processes, and the oxygen flow control is essential for the improvement. A stable, precise and precise oxygen flow is a prerequisite for the production of high quality steel.
Oxygen flow is the key factor controlling steelmaking process. When oxygen opens the converter lid, it appears in the form of a mist, filling the converter for a few seconds. Then the oxygen is evenly distributed inside the converter, so that the reactants can react correctly. Too little oxygen will reduce steel quality, too much oxygen will increase fuel consumption and noise, affect steel making efficiency and reduce steel quality. Properly controlling oxygen flow while producing high quality steel is the key to producing satisfactory steel.
To improve the oxygen temperature in the steelmaking process, the temperature must be controlled. The higher the temperature, the higher the reaction rate, the faster the operation and the higher the quality of the steel. Temperature control must be done in small increments to achieve the desired oxygen flow. However, the installation of thermocouples on the large converters is difficult, as they have a long distance from the top of the converter to the bottom. Installing a whole wall of thermocouples is also a problem. The piping of the temperature sensor could be blocked or destroyed by the smelting slag, and controlling the oxygen flow requires a continuous and accurate flow measurement.
In order to ensure an accurate and stable oxygen flow in the steelmaking process, several new technologies can be used, such as a double-sealing oxygen valve, an oxygen flow control valve or an oxygen diffuser. The double-sealing oxygen valve is made of special material and has two seals to ensure the stable flow of oxygen. The oxygen flow control valve can be operated remotely, allowing the opening and closing of the valve to be monitored remotely. The oxygen diffuser contains an automatic moderator to adjust the oxygen flow precisely. All of these technologies can improve the oxygen flow in the converter steelmaking process, so that the steelmakers can make higher quality steel with a steady and precise oxygen flow.
In summary, the oxygen flow in converter steelmaking has a significant influence on the steelmaking process and its quality. Various technologies can be used to improve the oxygen flow, such as a double-sealing oxygen valve, an oxygen flow control valve and an oxygen diffuser, which helps the steelmakers to make more accurate and stable steel. To ensure the production of higher quality steel, the accuracy and stability of oxygen flow must be strictly monitored and adjusted.
