Abstract As for the techno-interface of CC-HR region, temperature changing regularity of slab are studied during continuous casting, conveying, stack cooling and heating units in typical slab process flow by mathematical simulation and field measurement. The results are as follows: ①when conveying temperature of slab is in the range of 750~ 900℃, the difference of cooling rate is insignificant as different section and same position, the difference of cooling rate is insignificant as different conveying temperature of slab and same position, but the difference of cooling rate is significant between slab surface and center, the cooling rate of slab-narrow is 6.3 K8226;min-1 , the cooling rate of slab-broad is 7.0 K8226;min-1 , the cooling rate of slab center is 8.7 K8226;min-1. ② The cooling rate of stack cooling is between 8.1 K8226;h-1 and 14.2 K8226;h-1.③ The difference of thermal history of slab surface and center is significant during hot-charging.
