NON-ORIENTED ELECTRIC STEEL PRODUCED BY THIN SLAB CONTINUOUSLY CASTING AND ROLLING AND PRODUCING METHOD THEREOF

摘要

A non-oriented electric steel comprises, in weight percentage, C≤0．008%，Si：0.15～2.2%，A1≤0.008%, Mn0.15～1.5%, P0.004～0.15%, S≤0.008%,［O］≤ 40 PPm, N≤0.005%, Ti≤0.008%, balance Fe and unavoidable impurities. A method for producing the non-oriented electrical steel is also provided, which comprises the following steps: smelting in converter and treating in vacuum, continuously casting into plate blank with thickness of 50-90mm, soaking in a tunnel furnace, continuously rolling with seven-roller mill, coiling, pickling, cold rolling, re-crystallization annealing and standby.
