<p>A cold rolling method for preventing high silicon strip steel from breaking, wherein the content of Si in the high silicon strip steel is no less than 2.3wt%, comprises the following steps: controlling the temperature of the strip steel at the entrance at over 45℃ at the beginning of cold rolling, injecting the emulsion onto the strip steel during cold rolling, controlling the flow of the emulsion at the entrance along the rolling direction at not more than 3500l/min, and controlling the flow of the emulsion at the exit along the rolling direction at 1500-4000l/min, and controlling the temperature of the strip steel no less than 45℃ under the condition of ensuring lubrication in the process. Thus, the production yield and producing efficiency can be improved.</p> |
