Abstract

The solidification and cooling of a continuously cast billet, slab or cylinder— generally a concasting—and the simultaneous heating of the crystallizer is a very complicated problem of three-dimensional (3D) transient heat and mass transfer. The solving of such a problem is impossible without numerical models of the temperature field of the concasting while it is being processed through the concasting machine (CCM). An important part of the CCM is the so-called secondary-cooling zone, which is subdivided into thirteen sections—the first section engages water jets from all sides of the concasting and the remaining twelve engage air-water cooling jets positioned only above the upper and beneath the underside of the concasting.
