Effects of Casting Flux Interaction with Steel Melt on Lubrication in CC Moulds
Lubrication in CC moulds controls the shear forces to the sensible strand surface. Since that friction forces are depending on casting speed and the flux behaviour, a study on lubrication have experimentally been carried out when the slag is in contact with liquid steel. Particularly, higher amounts of aluminium in the steel as for pure de-oxidation lead to remarkable redox-reactions and to modified casting slags for the gap between strand and mould. Friction coefficients have been determined and applied to several strand shapes and castings velocities.
