The invention provides a method for solving differences between the center of a larger-size 82B wire rod and the edging tissue thereof, belonging to the technical field of high carbon steel. In the method, the characteristic that chrome can reduce the beginning and the ending phase transformation temperatures of the 82B steel is adopted, 0.04%-0.06% of Cr is added on the basis of 82B steel components, the opening of fans is adjusted at 85% by the wire rod from the 4-6m position before phase transformation to the starting point of the phase transformation, all fans are opened from the phase transformation position to the wire rod 490-510 DEG C position, and then all fans are closed until the gathering coil packaging is carried out. The invention has the advantage that the sorbitic rate of 82B wire rod is lower in the specification of phi 15-16mm is solved by Stelmor cooling process.
