Cas Ob. PDF fileThe CASOB (composition adjustment by sealed argon bubbling oxygen blowing) process is used in secondary steelmaking to adjust the composition and temperature of the steel melt The steel melt can be heated by oxidizing aluminium in process which feeds aluminium particles and oxygen to the melt surface.
A modelbased system for realtime monitoring and operational support has been developed for the Composition Adjustment by Sealed argonbubbling with Oxygen Blowing (CASOB) process The model of the system is based on a previously developed dynamic model using first principles ie mass and energy balances reaction kinetics and thermodynamics.

The CASOB Process Abstract The continuous relationship between producing the cleanest possible steel at the lowest possible price remains and ongoing challenge in the industry Composition adjustment by sealed argon bubbling – oxygen blowing is one unit process in secondary metallurgy which can help in this quest In recent years the demand for clean steel.

The CASOBprocess was developed by Nippon Steel Corporation (Ghosh 2001) Fig 1 Sketch of the CASOBprocess (Järvinen etal 2014) At the start of the CASOB process molten steel from a primary steelmaking process is poured into a ladle The ladle consists of a steel casing with a refractory brick layer on the inside.
