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...

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

Continuous Casting

Continuous casting is used to mass produce basic metals into long, semi-finished shapes with constant cross section, which are later processed into over 800 million tons of steel, 20 million tons of aluminum, and 1 million tons of copper, nickel, and other metal products in the world each year. Cross-sections can be rectangular, for later rolling into plate or sheet, square for long products, c...

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...

Thermal Simulation of Solidification Process in Continuous Casting

In this study, a mathematical model is introduced to simulate the coupled heat transfer equation and Stefan condition occurring in moving boundary problems such as the solidification process in the continuous casting machines. In the continuous casting process, there exists a two-phase Stefan problem with moving boundary. The control-volume finite difference approach together with the boundary ...
