(p285) Next steps in high-speed billet casting at Ege Celik (Aliaga, Turkey)

摘要

After successful trials were executed at Ege Celik (Aliaga, Turkey) - where a casting speed of 6.2 m/min on a130x130 mm section was achieved on machine CCM4 - more trials followed that stabilized the process in terms ofsteelmaking requirements and the casting machine set-up. Unique measurement instrumentation was utilized tocollect a vast array of data, including temperatures in the mold, actual negative strip time measured below themold, and laser measurement of the actual casting speed. An evaluation of the resulting data helped define thebest machine characteristics for the high-speed casting of long products and led to the development of the latestPrimetals Technologies high-speed billet mold.This paper describes the latest results obtained from the high-speed trials at Ege Celik and highlights some of thenew features of the next generation of high-speed/high-quality molds.
