[0035] The following is a detailed description in the form of a table:
[0036] Non-oriented electrical steel produced by continuous casting and rolling of thin slabs, the chemical composition and weight percentage of the following examples are: C: ≤0.008%, Si: 0.15~2.2%, Al: ≤0.008%, Mn: 0.15~ 1.5%, P: 0.004~0.15%, S: ≤0.008%, [O] ≤ 40PPm, N: ≤0.005%, Ti: ≤0.008%; process and process parameters are selected according to the following steps and range :
[0037] A method for producing non-oriented electrical steel produced by continuous casting and rolling of thin slabs, the steps of which are as follows:
[0038] 1) Carry out converter smelting and vacuum treatment;
[0039] 2) Continuous casting into a slab with a thickness of 50-90 mm, and the casting speed is controlled at 3-5 m / min;
[0040] 3) Soak in the tunnel furnace, and the soaking temperature is controlled at 1000-1200°C;
[0041] 4) Carry out continuous rolling with seven rolling mills, and control the final ro...
