A PARAMETRIC STUDY OF THE HAZELETT THIN-SLAB CASTING PROCESS

A parametric study is presented for the Hazelett thin-slab steel casti ng process. The paper investigates the influence of the belt heat tran sfer, steel superheat, casting speed, and nozzle diameter on the growt h of the solidification front within the easter. The numerical results compare well with results available in the literature and show that t he belt heat-transfer and casting speed are the process parameters tha t are most influential on the development of the solidification front. In addition, the influence of the major process parameters on the coo ling rates in the easter is investigated also. A fixed-grid enthalpy f ormulation is used allowing, with a single set of equations, the descr iption of the liquid region, the two-phase mushy zone, and the solid r egion.
