The invention relates to rolling mill mounting, particularly to a reserved hoisting method for a base of a large rolling mill stand. The reserved hoisting method for the base of the large rolling mill stand comprises the following steps: reserving a part of base not to be constructed during foundation construction around a base pit of the rolling mill stand; after hoisting the rolling mill stand, constructing; obliquely placing the rolling mill stand in a direction parallel to a rolling line on a base plate on the reserved base; jointly hoisting a carrying pole beam which is provided with a rotary hook head in the middle by using main hooks of two cranes; hoisting the rolling mill stand by using the carrying pole through a steel wire rope, wherein the rolling mill stand rotates and stands upright and the rolling mill stand rotates 90 degrees by using the rotary hook head of the carrying pole beam after the rolling mill stand stands upright and is translated and placed in a mounting position of the rolling mill base. The method provided by the invention greatly reduces the requirement on crane hoisting height, overcomes the deficiency of conventional two-crane hoisting method and expands the two-crane hoisting application range.
