Temperature profiles for the liquid steel in both ladle and Tundish

The ladle and tundish steel temperatures change over time. The

aim is to order ladles with the right temperatures.

If the temperatures are

Too low , there is a risk of solidification in either the ladle

or the tundish;

Too high , the superheat can have adverse effects on the

subsequent strand quality, increased wear of refractories,

and of course the increased cost of heating the ladle steel.

Misalignment StrainMisalignment of rolls in continous casting results in the

production of strains, known as misalignment strains, εM. These strains can be either tensile or compressive dependent

upon the misalignment direction. In the simulation positive strains indicate tensile strain and negative strains indicate compressive strain.

To calculate εM, the following equations is used:
