The invention discloses a rolling method for a hypereutectoid steel continuous casting billet. The rolling method comprises the following steps that firstly, the temperature of the continuous castingbillet is slowly raised to 650 DEG C in a preheating segment of a heating function, after austenitizing is completely finished, the heating speed is increased, the temperature of the preheating segment is smaller than or equal to 900 DEG C, the preheating time is larger than or equal to 3.5 hours, the temperature of a heating segment is controlled within 1,200 DEG C-1,250 DEG C, the heating time is larger than or equal to 5 hours, the temperature of a soaking zone is controlled within 1,180 DEG-1,230 DEG C, and the soaking time is larger than or equal to 1.5 hours; secondly, the water pressureof high-pressure water dephosphorization and re-high-pressure water dephosphorization are both 20 MPa-25 MPa; thirdly, the rolling temperature is controlled within 1,100 DEG C-1,150 DEG C; fourthly,after rolling, a 200 mm*200 mm square billet is obtained; fifthly, soaking is carried out again, the temperature is controlled within 1,180 DEG C-1,230 DEG C, and the soaking time is larger than or equal to 1.5 hours; sixthly, rolling is carried out again; and seventhly, after saw cutting sizing, the billet enters a delayed cooling pit to be subjected to slow cooling, the temperature of the billetentering the delayed cooling pit is larger than or equal to 650 DEG C, and the slow cooling time in the delayed cooling pit is larger than or equal to 48 hours. The rolling method has the beneficialeffects that the process is simple and convenient to conduct and production organization is convenient.
