Abstract

PURPOSE:To manufacture the cast billet possessing the sectional shape possible to prevent generation of the so called fish tail especially during the hot rolling pass, by pressing the cast billet, which has finished the secondary cooling and is before the cutting machine, from both sides with the pressing head possessing a cavity of specified shape fittable to the side plane of this cast billet. CONSTITUTION:The molten metal in the casting mold 1 is extracted as the cast billet 3 following to the rotation of the extracting rolls 5, 5, and is successively passed through the cooling zone 4 to solidify. Next, this completely solidified cast billet 3 is pressed from both sides by the pressing heads 14, 14, possessing the cavity 17 in order to reduce the breadth of the cast billet 3, and at the same time, the bulging of the billet metal toward the direction of thickness due to this pressing work is restrained by the upper and lower contact surfaces 21, 21. As a result, the cast billet of irregular sectional shape can be cheaply, easily manufactured without using the special casting mold in the continuous casting line.
