METHOD FOR HOT ROLLING OF ELECTRICAL ANISOTROPIC STEEL

rolled stock production, possibly manufacture of electrical steels, particularly by hot rolling of continuously cast ingots of electrical anisotropic (transformer) steel to strips with thickness (2- 3.5)m. SUBSTANCE: method comprises steps of rolling ingots of electrical anisotropic steel in rough group of continuous rolling mill according to next schedule: in first stand of rough stand group subjecting slab to reduction no more than 5% sufficient for loosening furnace scale; in second stand of rough group subjecting slab to reduction no more than 35%; then increasing reduction values in third and forth stands of rough group by 5-10% in each stand next relative to previous one; selecting reduction value in fifth stand of rough group according to rolled piece thickness determined in dependence upon mass content of silicon in steel with use of relation : (40-41)mm for (2.8-3)% of Si, (42-44) for (3.01-3.4)% of Si. EFFECT: possibility for increasing temperature at final stage of strip hot rolling. 3 cl, 2 dwg, 1 ex
