Abstract

Disclosed is a non-oriented electrical steel plate without corrugated fault and production method thereof. The steel has the components as follows: C of not more than 0.005 wt%, Si 1.2-2.2 wt%, Mn 0.2-0.4 wt%, P not more than 0.2 wt%, S not more than 0.005 wt%, Al 0.2-0.6 wt%, N not more than 0.005wt%, O not more than 0.005 wt% and balance Fe. A slab is obtained by pretreating molten iron, smelting in converter, RH refining and continuous casting, wherein the second cooling water amount in continuous casting is controlled to keep the specific water capacity at the level of 100-190 l/min and the average degree of superheat of molten steel in continuous casting at 10-45 °C. The slab is then subjected to heating and hot rolling, wherein the tapping temperature is 1050-1150 °C and the temperature difference between any two points along the longitudinal direction is less than 25 °C during heating. The hot rolling includes rough rolling and finish rolling. Inlet temperature of the finish rolling is not less than 970 °C. The final product of non-oriented electrical steel plate is then obtained by acid pickling, cold rolling, annealing and coating. The present invention avoids corrugation faults by controlling the slab cooling rate in continuous casting, the temperature difference of the slab along the longitudinal direction in heating furnace and the temperature drop of the slab before refine rolling.
