Abstract

A process for producing silicon steel sheet having the (100) plane in the rolling plane comprises taking an ingot of 2.0-4.0% Si, 0.010-0.150%C, 0.010-0.060% acid soluble Al, inevitable impurities, and the balance Fe, rolling the ingot to a slab, hot rolling the slab in arc direction at a temperature between 800 DEG and 1250 DEG C. with a reduction of greater than 20%, hot rolling in a direction at right angles to the pivot direction at a temperature of at least 600 DEG C. and with at least 40% reduction, and cold rolling and annealing the sheet to produce recrystallization grains having (100)[001] and (100)[011] orientation. In an example a 500Kg ingot containing 0.045%C, 3.02% Si, and 0.030% acid soluble Al was bloomed longitudinally to form a 100 mm thick slab, the slab was soaked at 1250 DEG C. for 30 minutes, cross rolled to 30 mm thickness, and again hot rolled after turning through 90 DEG C. to form a 3 mm thick sheet, the temperature then being 750 DEG C. After annealing at 950 DEG C. for 5 minutes, and pickling, the sheet was cold rolled in the same direction as the final hot rolling to 1.08 mm, decarbonized in wet H2, annealed in a N2-H2 atmosphere at 1200 DEG C. for 20 hours, cold rolled to 0.32 mm., and finally annealed in H2 at 1200 DEG for 20 hours to produce a double-oriented silicon steel.
