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...
متن کاملSUBMERGED ENTRY NOZZLE CLOGGING DURING CONTINUOUS CASTING OF Al-KILLED STEEL
F. Tehovnik, J. Burja, B. Arh, Institute of metals and technology, Ljubljana, Slovenia, M. Knap, University of Ljubljana, Faculty of Natural Sciences and Engineering, Ljubljana, Slovenia Nozzle clogging is a common problem in the production of continuously cast Al-killed steels. Clogging occurs when there are solid inclusions in molten steel at casting temperatures. SENs (Submerged entry nozzle...
متن کاملTurbulent Flow and Particle Motion in Continuous Slab-Casting Molds
Turbulent flow in the continuous casting process involves transient phenomena and the transport of inclusion particles and plays an important role in the quality of the steel. As shown in Fig. 1, the molten steel jet entering the mold may carry inclusion particles (e.g. alumina) and argon bubbles. Liquid flux can also be entrained from the shear of the liquid flow across the top surface and for...
متن کاملMicrostructure Formation in Thin Slab Casting
New processes have been developed in the last years to produce near net shape steel products by continuous casting. This work deals with the analysis of the effects of liquid core reduction during the solidification in the microstructure of thin slabs obtained by continuous cast process. An equipment able to simulate the liquid core reduction during the solidification was projected and construc...
