PURPOSE:To improve end-face shape of rapid cooled thin hoop by arranging an end-face press faced to end-faces of cooling rolls, heating and further forming a gap satisfying the specified equation on the gap between end-face press and the end-faces of the cooling rolls. CONSTITUTION:The end-face press 7 is arranged so as to face to the end-faces of the cooling rolls 3, 3 and together with a holding device 8 are formed as an end-face pressing block 9. Then, the gap (d) between the end-face press 7 and the end-faces of the rolls 3 is settled as satisfying the equation (I). Further, a heater 11 for heating an inside of the end-face press 7 is arranged so as to enable temp. control to the end-face press 7 made of refractory. In this mechanism, by existence of the gap (d) between the end-faces of the rolls 3 and the end-face press 7, they are prevented from wearing loss caused by sliding, and from leakage of molten metal. Therefore, the solidified thickness at the end-face part of the thin hoop is uniformized and the end-face shape is improved.
