The invention relates to a cold rolling control method for high-silicon thin-strip non-oriented silicon steel. The cold-rolling non-oriented silicon steel comprises the following components in percentage by weight: Si, which is more than or equal to 3.0 percent, and Al, which is more than or equal to 0.8 percent, and the thickness of a finished product is less than or equal to 0.35 mm. During thefirst cold rolling pass, the thickness transition rolling is adopted within the range of 30-50 m from the tail part of the strip steel, at least 2 pairs of friction rollers are arranged in front of arolling mill on the threading side of the second cold rolling pass, and the edge part of the strip steel is subjected to friction heating. The friction rollers are additionally arranged behind the cold rolling and uncoiling device of a single-stand reversible rolling mill, the friction rollers are put into use when the threading side of the second cold rolling pass is lifted, the friction rollersare stopped being used when the thickness of the strip steel is transited to a normal control range, and meanwhile, the edge of the strip steel is heated more uniformly by controlling the cold rollingprocess, so that the production difficulty is reduced, and the brittle failure rate is reduced.
