Abstract

Abstract

High titanium steel has high wear resistance, toughness, strength and intergranular corrosion resistance, and has been widely applied to many fields. In present work, the solidification process and the theoretical reduction amount of the high titanium steel continuous casting slab were numerically investigated. The results indicate that the shell thickness at the exit of crystallizer is 15 mm, and the solidification end is located at 20.4 m from the meniscus with the mushy region length of 10.8 m, at the casting speed of 1.0 m/min. With the casting speed increased by 0.1 m/min, the shell thickness at the exit of crystallizer decreases by 0.2 mm, and the solidification end moves backwards by about 1.7 m, with the mushy region length increased by 0.9 m. The required theoretical reduction amount for compensating the solidification shrinkage of the mushy region keeps at about 2.2 mm under different casting speeds.
