Control issues in continuous casting of steel

نویسنده

  • C. Furtmueller
چکیده

Continuous casting plants are highly complex plants whose performance requires reliable mold level control system. Several effects greatly influence the surface quality of the final product and if these are not suppressed sufficiently by the mold level control system, than the production speed, hence the productivity has to be lowered. This paper analyses the most important disturbance and their effects on the control system design, and presents a new solution for the most critical case, mold level hunting.

Physical Modeling of Steel Delivery during Thin Slab Continuous Casting

A full scale physical model of a thin slab caster with a four-hole design submerged entry nozzle (SEN) was constructed. On the basis of the dimensionless Reynolds and Froude similitude criteria, the fluid flow in a full-scale model is similar to that of the actual system and, hence, the data obtained from the water model can be applied to the actual system. In order to determine the optimum ope...

Mathematical Modeling of Heat Transfer for Steel Continuous Casting Process

     Heat transfer mechanisms and the solidification process are simulated for a continuous casting machine and the geometric shape of the liquid pool is predicted considering different conditions. A heat transfer and solidification model is described for the continuous casting of steel slabs. The model has been established on the basis of the technical conditions of the slab caster in the con...
