摘要： A metal strip is continuously cast through a gap of a pair of internally cooled rolls rotating in the opposite direction to each other having a pair of side dams disposed on both sides of the rolls and a pair of longitudinal dams disposed with their bottom surfaces held slightly above the roll surfaces so that openings are formed between the bottom surfaces of the longitudinal dams and the roll surfaces and that during steady state operation of the apparatus the openings are positioned at a level of the surface of molten metal in the pool. The longitudinal dams are capable of preventing formation of triple point solidified shells and make it possible that the surface of molten metal may come in contact with the surfaces of the rolls while forming the transversely uniform contacting edges, and therefore, the apparatus produces metal strips having enhanced surface quality which are substantially free from molten metal wrinkles. The advantages are further promoted by using a pouring device having a slit-shaped nozzle.
摘要翻译：金属条通过一对内部冷却的辊的间隙连续铸造，所述辊的内侧冷却辊在彼此相反的方向上相互旋转，所述一对内侧辊具有设置在辊两侧的一对侧挡块和一对纵向坝，在辊表面之上，使得在纵向坝体和辊表面的底表面之间形成开口，并且在设备的稳态操作期间，开口定位在池中的熔融金属表面的水平面上。纵向堤坝能够防止形成三点凝固壳体，并且使得熔融金属的表面可能在形成横向均匀的接触边缘的同时与辊的表面接触，因此，该设备产生金属带，其具有增强的基本上没有熔融金属皱纹的表面质量。通过使用具有狭缝状喷嘴的浇注装置进一步促进了优点。
