Title: Continuous casting method for steel containing silicon
Inventor: NAKADA MASAYUKI
IPC: B22D11/114
Filed: 1986-11-10
Abstract: PURPOSE:To form the finer ferrite crystal grains of solidified structure and to prevent generation of surface cracking by supplying electric current periodically at a specific current density to the molten steel, which is not solidified, in an ingot at the time of continuous casting. CONSTITUTION:The electric current is impressed to the ingot right under a casting mold 1 in the case of continuously casting a steel contg. 4-7wt% silicon. More specifically, a switch 11 is opened to supply electric power from a power supply 12 via a current rectifier 13 and a resistor 14 to a capacitor 11. The electric charge which is discharged from the capacitor 10 is applied through rolls 7 to the molten steel 3 in the ingot 4 when the switch 11 is closed and the electricity is instantaneously discharged from the capacitor. Pinching force is impressed to the ingot 4 if the current to be applied to the ingot 4 or the molten steel 3 is of the density as high as >=100A/cm<2>. The pinching force is repeatedly applied to the ingot by repeating the opening and closing of the switch 11 to break down or bend the dendrite arm existing at the solidification boundary of the ingot 4. Fresh grain boundaries are thereby generated in the solidification region of the ingot and the finer ferrite crystal grains are formed.
