This invention relates to a production method of a directional electromagnetic steel sheet used as a core material for a transformer, a motor, a generator, and other electromagnetic appliances. A component system is designed so that a directional electromagnetic steel sheet of a conventional system is heat-treated at approximately 1,250 to 1,300°C which is the same slab heating temperature as in the treating condition of general steels, and is then hot rolled. In this way, the present invention only requires operation in existing production processes without reinforcing the installation or establishing a new one, and stably forms secondary recrystallization in the (110) [001] orientation by securing stably a grain growth restriction force. Therefore, the present invention provides an improved directional electromagnetic steel sheet production method in which a preliminary annealing step is omitted, decarbonization/annealing is carried out at an intermediate thickness and machining energy at a final rolling step is lowered, so as to obtain stable magnetic characteristics. The gist of the present invention resides in a method of producing a directional electromagnetic steel sheet comprising hot rolling, after heating, a slab having a composition consisting, in terms of wt.%, of 0.035 to 0.050 % of C, 2.9 to 3.3 % of Si, not greater than 0.015 % of P, 0.011 to 0.017 % of dissolved Al, 0.0080 to 0.012 % of N, not greater than 0.007 % of S, 0.06 to 0.18 % of Ni+Cr, not greater than 0.32 % of Mn satisfying the condition of Mn/S: 20 or more, not greater than 0.6 % of Cu satisfying the condition Cu/Mn: 1.5 or more, and the balance of Fe, at 1,250 to 1,320 °C, regulating the rolled sheet to a final thickness by two cold rolling operations including an intermediate decarbonization/annealing without conducting annealing of the hot rolled sheet, then effecting intermediate annealing and annealing using MgO as the principal component, applying a separating agent, and thereafter conducting final finish annealing to produce a directional electromagnetic steel sheet having excellent magnetic characteristics.
