Abstract：In order to obtain high-quality laminated metal composites, the effect of coupling between process parameters on composite casting and rolling was investigated based on the two-roll thin strip composite casting and rolling technology. Finite element software was used to construct the solid-liquid composite casting and rolling simulation model of copper and aluminum. Based on this model, the effects of aluminum plate exit thickness, rolling speed, melt pool height, copper strip thickness and pouring temperature on Kiss point height were investigated. The Kiss point height obtained from the orthogonal test was subjected to extreme difference analysis to get three strong coupling parameters of aluminum plate exit thickness, rolling speed and copper strip thickness, and gave the variation law of coupling strength under two coupling parameters. The coupling effect of aluminum plate exit thickness and copper strip thickness, copper strip thickness and rolling speed on Kiss point height gradually decreases with the increase of parameter value, and the coupling effect of aluminum plate exit thickness and rolling speed on Kiss point height gradually increases with the increase of parameter value. At the same time, the cause of coupling was analyzed by the physical field change of composite casting and rolling melt pool.
