Abstract
PURPOSE:To increase equi-axed crystal zone in the central part of a casting piece and elevate the casting piece quality, by applying supersonic waves with rolls to two special places which have unsolidified molten steel in the casing piece in case molten steel is cast continuously. CONSTITUTION:The molten steel in the tandish 1 is poured into the water cooling copper mold 4 for continuous casting with the soaking nozzle 3, and is guided with the guide rolls 8 and is drawn out. In this case, the supersonic wave vibration of 12kHz is applied with two sets of rolls of 9A, 9B and 10A, 10B in the area where the columnar crystal is normally growing within the range that the unsolidified molten steel 6 exists in the central part of the continuous casing piece 7. The columnar dendrite which is growing in the casting piece is separated with the rolls 9A, 9B of the first position. The columnar crystal in the casting piece where the columnar dendrite is growing again, is solidified and lowered is separated once again, and it is possible to produce the continuous casting piece with excellent casting texture, which has little columnar dendrite and much equi-axed crystal.
