The invention discloses a process for performing continuous annealing on a low-carbon aluminum killed steel belt. The low-carbon aluminum killed steel belt comprises the following chemical components in percentage by weight: less than or equal to 0.04 percent of C, less than or equal to 0.02 percent of Si, less than or equal to 0.28 percent of Mn, less than or equal to 0.045 percent of Al, less than or equal to 0.02 percent of P, less than or equal to 0.01 percent of S, less than or equal to 0.003 percent of N, and the balance of Fe and inevitable impurities; the low-carbon aluminum killed steel belt is subjected to cold rolling and then is subjected to continuous annealing, and the reduction rate of the cold rolling is controlled to be 70 to 80 percent; the continuous annealing process comprises the following steps of: 1) heating, namely heating from room temperature to 750+ / -10 DEG C at the speed of 150+ / -5 DEG C / s; 2) soaking, namely soaking at the temperature of 750+ / -10 DEG C for 5 to 15s; 3) rapidly cooling, namely cooling to 460+ / -10 DEG C at the speed of 18+ / -2 DGE C / s; 4) soaking, namely soaking at the temperature of 460+ / -10 DEG C for 2 to 5s; 5) slowly cooling, namely cooling to 200+ / -10 DGE C at the speed of 13+ / -2 DEG C / s; and 6) spraying water to cool to room temperature. The mechanical property of a continuous annealing steel plate which is produced by the method is kept almost unchanged, the continuous annealing time is shortened, and the energy consumption is reduced.
