PURPOSE: A method is provided to produce an oriented electric strip having excellent magnetic property in a temperature of 1200 to 1280°C wherein melting scale is not generated and the strip is easily rolled. CONSTITUTION: A silicon steel slab is composed of 2.0 to 4.5wt% of Si, 0.010 to 0.095wt% of C, 0.010 to 0.040wt% of sol-Al, 0.002 to 0.020wt% of N, 0.05 to 0.45wt% of Mn, 0.002 to 0.20wt% of S, the remain of Fe and incidental impurities. The silicon steel slab is reheated in a low temperature and hot rolled and then annealed. Then, the slab is cold rolled in a final thickness, decarbonized, coated with an annealing separating agent and finally annealed to be an oriented electric strip.
