ELECTRICAL ANISOTROPIC STEEL HOT ROLLING METHOD

Ordinary methods of electrical anisotropic steel hot rolling on the continuous wide-strip rolling mill include rolling of continuously cast slabs in the rolling mill roughing train; breakdown bar cooling during its feed over the roller bed between the roughing and finishing trains, hot deformation in the finishing train and air cooling of the bar in the gaps between the mill stands; cooling of the hot rolled bars on the collecting roller table. The invented technology differs in that in the last but one gap between the stands the bar is cooled with water with the total water flow set according to the dependence: Q = 12.15*(326 - t_RG + 0.518t₆ + 23.97h₁₂), where Q is the total water rate of flow for cooling, m³/h; h₁₂ is the thickness of the bar after the 12th (last) stand, mm; t₆ is the temperature of the breakdown bar at the inlet to the 6th stand of the finishing train, ^oC; t_RG is the rolling end temperature, ^oC.
