  • Cold-rolling method for preventing fracture of high-silicon strip steel
    Patent number: 9056343
    Abstract: A cold-rolling method for preventing fracture of high-silicon strip steel, characterized in that the high-silicon strip steel has a Si content ?2.3 wt %, and at the beginning of cold-rolling, the temperature of inlet strip steel is above 45° C.; during the cold-rolling process, an emulsion liquid is sputtered to the strip steel, a flow rate of the emulsion liquid is 3500 L/min at the inlet in rolling direction, a flow rate of the emulsion liquid is 1500-4000 L/min at an outlet in the rolling direction, and the temperature of the strip steel is maintained above 45° C. under the precondition to guarantee technological lubrication. The cold-rolling method of the invention might prevent fracture of a head portion and a tail portion of the strip steel, raise the rate of finished products, and increase production efficiency.
