On the Secondary Cooling of Continuous Casting

Evaluation of Heat Transfer Coefficients along the Secondary Cooling Zones in the Continuous Casting of Steel Billets

In the present work, heat transfer coefficients (h) along different cooling zones of a continuous caster billet machine were determined during casting of low and medium carbon steels. The effects of casting parameters, such as machine characteristics, the ingot dimension, mold, sprays zones, radiant cooling, melt composition and casting temperature were investigated and correlated with heat tra...

Effects of High Cooling Rates on the Improvement of Continuous Steel Casting Microstructure

A. Mahmutović, University of Zenica, Faculty of Metallurgy and Materials, Zenica, Bosna and Herzegovina This paper has r esearched into the infl uence of trace elements in st eel, combined with new casting pr ocesses, on the microstructure and micr o-segregation phenomenon in the case of struc tural steel. Thermocalc sof tware has been applied for calculation of steel phase. In the paper, close...

The Use of Water Cooling during the Continuous Casting of Steel and Aluminum Alloys

In both continuous casting of steel slabs and direct chill (DC) casting of aluminum alloy ingots, water is used to cool the mold in the initial stages of solidification, and then below the mold, where it is in direct contact with the newly solidified surface of the metal. Water cooling affects the product quality by (1) controlling the heat removal rate that creates and cools the solid shell an...

Control Technology of Solidification and Cooling in the Process of Continuous Casting of Steel

Simulation of the Continuous Casting and Cooling Behavior of Metallic Glasses

The development of melt spinning technique for preparation of metallic glasses was summarized. The limitations as well as restrictions of the melt spinning embodiments were also analyzed. As an improvement and variation of the melt spinning method, the vertical-type twin-roll casting (VTRC) process was discussed. As the thermal history experienced by the casting metals to a great extent determi...
