Ladle stirring is a
key stage in the secondary steelmaking process.
Objectives
After studying this section, you should be able to:
- to explain the purpose of ladle stirring (& standing);
- to relate where this process occurs in the overall steelmaking
route;
- to explain why large
inclusions in the molten steel float to the surface
faster than small ones;
- to use Stokes' law to estimate the float rate, u
of a particle as a function of its diameter, d.
- to explain why gentle stirring is a useful steel cleaning
technique.
