Abstract：In order to reduce the energy consumption of reheating slabs between the continuous casting and the hot rolling process，the Continuous Casting-Direct Rolling(CC-DR) process is developing vigorously. One of the key technologies in the CC-DR is the concurrent heating between the continuous casting and the rolling process. In view of the requirement of concurrent heating technology in the actual production of slab CC-DR，the finite element models of the longitudinal flux and transverse flux medium frequency induction heating are established to analyze the slab heating process. The results show that the longitudinal flux induction heating is good for heating the surfaces of the slab，but it cannot solve the problem of the low temperature at edges. The transverse flux induction heating can effectively heat the slab edges. The temperature distribution of the slab can be more uniform by choosing the appropriate current and slab moving speed. Besides，induction heating prototypes are made to inspect the effect of induction heating by concurrent heating experiments. The measured results are well consistent with the simulation ones. The analysis results have directive significance for the induction heating process in the actual production of slab CC-DR.
