Abstract：Strip casting is a new technological revolution in the metallurgical industry and an advanced preparation technology of steel materials with short process. In production, the solidification time of liquid steel is only 0.2 s, and the interfacial heat transfer behavior between molten steel and casting roll is more rapid and complex than that of traditional continuous casting, and the heat transfer often has a great impact on the quality of the casting strip and the properties of the final product. The influences of key process parameters on interfacial heat transfer behavior during strip casting were reviewed, and the influences of naturally deposited film and coating of casting roll on heat transfer were mainly discussed, in order to provide theoretical and technical support for optimizing the key factors in the process and improving the quality of strip casting.
