Aiming to reduce the occurrence of the surface and internal defects in the products, a dynamic secondary cooling control system was developed. The purpose of the system was to keep the surface temperature of the strand constant regardless of changes in casting speed. To accurately predict and control temperature in real time during the continuous casting process, A fast, accurate transient solidification...
A two-dimensional heat-transfer model for transient simulation and control of a continuous steel billet caster was developed. Billet temperature and solidification were computed by the model as a function of casting speed, secondary spray cooling water flow rates and temperature, shell thickness, steel chemistry, and pouring and ambient temperatures. Typically, the solidification path, temperature-solid...
