Abstract
PURPOSE: To prevent the longitudinal cracking of an ingot and improve productivity in continuously casting the ingot, by using the flux of the viscosity meeting the mathematical expression with respect to the casting speed to be preset as a lubricant for the mold.
CONSTITUTION: In continuousy casting aluminum-killed steel or aluminum-silicon- killed steel, the flux of the viscosity η poise determined by the formula I with respect to the casting speed v (m/min) to be preset is added into the mold and with this as a lubricating the casting is performed. Here, the reason for limiting the viscosity range determined by the formula I is: If the viscosity is lower than the value of the formula of the left side, it becomes the cause for longitudinal cracking. If the viscosity becomes larger than the value of the formula of the right side, defects such as penetration of slag into the surface layer of the ingot metal and crazing are liable to occur.
