Optimization of Metal Flows in the Intermediate Ladle of a Continuous Caster

A three-dimensional mathematical model was developed to describe hydrodynamical and thermophysical processes in the intermediate ladle (one-, two- and six-strand continuous casters).

The software helps to fufill the following functions:

calculate the metal velocity fields in the intermediate ladle;
at different melt levels in the intermediate ladle;
determine the influence of the position of the stream, pouring out of the steel teeming ladle, on the character of the flow swirling in the intermediate ladle;
determine the mass velocities distribution when pouring out of the nonswirl nozzle;
estimate the performance of various sills and barriers in the intermediate ladle;
calculate the paths of nonmetallic inclusions motion.

The model can be used to choose the best geometric parameters and operating modes for the intermediate ladle, which ensure:

uniform stirring of the metal in the intermediate ladle;
minimal mixing of the metal with the slag;
uniform filling of continuous caster moulds with liquid metal.

The software is used to plan continuous casters being redesigned and those being newly constructed.

The mathematical models, calculation algorithms and the software realizing these functions were developed and adapted directly by the project’s authors and do not include any data of other authors.

The techniques and the software for their realization are executed at the state-of-the-art level taking into account the latest science and technology progress. The calculated design parameters for the intermediate ladles of shape and slab continuous casters are patentable on the territory of Ukraine and Russia.
