Abstract:
    The invention relates to a thermal rolling silicon steel production, which comprises irrigating the high-quality steel water via large pack and middle pack in the crystallizer; using crystallizer to mix electromagnetically; using gas at secondary cold section to protect and control cooling; using hydraulic core to compress or softly compress to thin 10-30mm; feeding it into rough rolling machine to be rolled and cooled via gas water; feeding into fine rolling machine, while the rolling start temperature is 1050-1100Deg. C, and the final rolling temperature is 960-1000Deg. C; then shearing and slicing; passing laminated cooler, to reduce the temperature at 10-40Deg. C/s into 600-750Deg. C; entering into underground coiler to be coiled; finishing and storing. The invention has high yield and quality with low cost.
