Degassing in the steelmaking process is a critical step aimed at removing dissolved gases, such as hydrogen, nitrogen, and carbon monoxide, from the molten steel. These gases can significantly impact the mechanical properties and quality of the final steel product, and can lead to issues like porosity, brittleness, and reduced ductility. The process typically involves exposing molten steel to a vacuum, which lowers the pressure and encourages the gases to form bubbles and escape. By reducing the gas content, the steel becomes cleaner and more homogenous, enhancing its performance.
