摘要： PROBLEM TO BE SOLVED: To accurately detect a crater end only from a value measured by a sensor without needing calibration based on a slab rivet method. SOLUTION: An ultrasonic shear wave sensor 6, 8 for transmitting an ultrasonic shear wave to a cast product 1 and receiving it and an ultrasonic longitudinal wave sensor 7, 9 for transmitting an ultrasonic longitudinal wave to the cast product and receiving it are installed at the same position in a continuous casting machine or at two positions apart in a casting direction. A casting velocity is increased, and a crater end 4 is moved to the downstream side than the installed position of the ultrasonic shear wave sensor. From variations in strength of a signal received by the ultrasonic shear wave sensor at that time, it is detected that the position at which the solid phase ratio of the central part in the cast product reaches 1 is matched with the installed position of the ultrasonic shear wave sensor. A calculation formula for determining the crater end from a propagation time of an ultrasonic longitudinal wave signal is calibrated such that the crater end computed from the propagation time of the ultrasonic longitudinal wave signal at that time is matched with the installed position of the ultrasonic shear wave sensor. After the calibration, the crater end is determined from the propagation time of the ultrasonic longitudinal wave signal based on the calibrated calculation formula. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To reduce the central segregation of a cast slab, and also, to improve the lives of segments composing a light rolling-reduction zone, when a continuously cast slab of steel is manufactured by gradually applying rolling reduction to the cast slab having an unsolidified inner portion with a rolling reduction speed corresponding to the amount of solidification contraction in the light rolling reduction zone arranged in the secondary cooling zone.
SOLUTION: In a method for manufacturing a continuously cast slab, the thickness of an unsolidified layer 14 inside the slab is increased by intentionally exerting a bulging force on a solidified shell 13 in an intentional bulging zone 17 arranged between a lower end of a continuous casting die 5 and a crater end of the liquid phase line of a cast slab 12, and then, in a light rolling reduction zone 16, the rolling reduction is applied to the slab with the rolling reduction speed within the range of 0.5-1.5 mm/min from the position where the solid phase ratio at the central portion of the thickness of the cast slab is 0.4 or lower until the position where the solid phase ratio at least at the central portion of the thickness of the cast slab becomes 0.7 or over. The total amount of rolling reduction of the cast slab is made equal to or smaller than the bulging amount of the cast slab when the cast slab is intentionally bulged.
