Non-oriented electrical steel for efficient motor and production method

The invention relates to non-oriented electrical steel for an efficient motor. The non-oriented electrical steel for the efficient motor is prepared from the chemical components in percentage by weight: less than or equal to 0.0030% of C, 1.9-2.1% of Si, 0.28-0.32% of Mn, 0.10-0.60% of Al, 0.01-0.06% of P, less than or equal to 0.0050% of S, 0.10-0.30% of Cu, 0.02-0.05% of Sb and less than or equal to 0.0030% of N. The production process comprises the following steps: smelting; cogging; repeatedly forging to obtain square billets; heating; hot-rolling; normalizing; pickling; cold-rolling; and thermally heating. By controlling the total weight of main alloy elements (Si+Al+Mn) and auxiliary elements (Cu+P+Sb), favorable effects of elements in physical metallurgy are fully exerted. By researching the composite effect of elements (Cu+P+Sb) on silicon steel organization structure and magnetism, partial (Si+Al) is replaced by (Cu+P). On the one hand, the inflection time of a normalized plate can be improved and on the other hand, the punching property of a finished plate is improved. The non-oriented electrical steel for the efficient motor excellent in magnetic property and good in punching effect is developed.
