UPWARD-DRAWING CONTINUOUS CASTING METHOD

摘要

In an upward-drawing continuous casting method according to one embodiment of the present invention, a starter (ST) is used to draw upward a molten metal (M1) held in a holding furnace (101). When accelerating the starter (ST) to a prescribed upward-drawing speed during casting initiation, the following intervals are provided: a first acceleration interval in which the starter is accelerated at a first acceleration from a stopped state to a first speed; a second acceleration interval in which the starter is accelerated at a second acceleration from the first speed to a second speed; and a constant speed interval which occurs between the first acceleration interval and the second acceleration interval, and in which the starter is drawn upward at the first speed.
