The present invention belongs to the technical field of silicon steel production, and in particular relates to a Hi-B steel produced using an intrinsic inhibitor method and a casting blank low-temperature heating process. The liquid Hi-B steel contains the following chemical components in mass percent: 0.04-0.065% of C, 3.1-3.3% of Si, 0.08-0.60% of Mn, 0.01-0.03% of P, less than or equal to 0.01% of S, 0.025-0.055% of Als, 0.007-0.013% of N, and 0.1-1.0% of Cu. The Hi-B is prepared with a sulfide serving as an auxiliary inhibitor and by means of the casting blank low-temperature heating process. According to the present invention, not only is low-temperature heating used for a casting blank, but also the process is wide in application range and sufficient in inhibition capability; and the Hi-B steel obtained according to the present invention has a value of B8 as high as 1.988T, and a value of P17/50 as low as 0.836W/kg.
