Latest Patents

John MacNamara holds a patent for the treatment of steel. This patent involves the sulphide modification of molten steel in the ladle. The treatment is achieved by adding an agent that is highly reactive to oxygen, such as rare earth metal compounds, particularly rare earth metal silicides. This addition occurs after a desired amount of deoxidation of the molten steel has taken place. The agent is enclosed in a metal container, preferably made of steel, which is suspended in the molten steel. This design ensures that the agent is distributed into the molten steel upon melting of the container's walls, allowing for precise control over the deoxidation process.
