本论文的目的是实现复合带材的一次铸造。因此，对立式双辊连铸机的复合带材的铸造能力进行了研究。使用双辊连铸机制造复合带材的目的是降低复合带材的生产能耗。设计/方法/途径：本研究中使用的是带有划线器的立式双辊连铸机。划线器用于防止两种熔体混合。将划线器设置在辊咬合处，并且划线器接触固化层之一。划线器使熔体停止，仅凝固层被辊拖动。结果：具有清晰界面的复合带材可以通过带有划线器的立式双辊连铸机生产。划线器可用于仅拖动固体和半固体层。两种带材在复合带材的界面处严格连接。由于连续弯曲，复合带材在界面处没有断裂。研究局限性/影响：本研究中是否铸造了 100 毫米宽的带材。宽度超过100mm的复合带材的性能尚不清楚。没有研究包层比的控制。实际意义：本报告中设计和研究的双辊连铸机可用于铸造复合带材，例如用于汽车散热器的钎焊板。独创性/价值：适合铸造复合带材的立式双辊独创工艺。划线器用于防止两种熔体混合。以往双辊连铸复合带材的研究中并未使用划线器，使用划线器尚属首次尝试。
Purpose: Of this paper is to realize the casting of the clad strip by only one process. Therefore, the investigation of the ability of the casting of the clad strip by a vertical type twin roll caster was operated. The aim of the use of the twin roll caster to make clad strip was in the reduction of the production-energy of the clad strip. Design/methodology/approach: Used in the present study was a vertical type twin roll caster with the scriber. The scriber was used to prevent the mixture of the two kinds of the melts. The scriber was set at roll-bite, and the scriber contacted to the one of solidification layer. The melt was stopped by the scriber and the only the solidification layer was dragged by the roll. Findings: The clad strip with the clear interface could be by the vertical type twin roll caster with the scriber. The scriber was useful to drag only the solid and semisolid layer. The two kinds of strips were connected strictly at the interface of the clad strip. The clad strip was not broken at the interface by the continuous bending. Research limitations/implications: Are that 100 mm width-strip was cast in the present study. Ability of the clad strip that is wider than 100 mm was not clear. The control of the clad ratio was not investigated. Practical implications: The twin roll caster devised and investigated in this report is useful to cast clad strip like the brazing sheet for the radiator of the automobile. Originality/value: The vertical type twin roll cater to cast clad strip is original process. The scriber was used to prevent the mixture of the two kinds of melts. The scriber was not used in the previous research to cast clad strip at the twin roll caster, and use of the scriber was the first try.
