Zusammenfassung:The invention provides an isothermal rolling method for an aluminum alloy ring piece, which comprises the following steps that an aluminum alloy ring blank is heated to a target rolling starting temperature for ring rolling, and the ring rolling comprises an adaptation stage, an acceleration stage, a stabilization stage, a deceleration stage and a rounding stage; the adaptation stage and the acceleration stage are used for controlling the cooling liquid amount to reduce the temperature rise trend; in the stable stage, the feeding speed and the rotating speed of a main roller are controlled, and the temperature drop trend is reduced; in the deceleration stage and the rounding stage, a main roller and a conical roller are heated, so that the finish rolling temperature of ring rolling is within a target temperature range. According to the method, isothermal rolling is adopted, the feeding speed and the rotating speed of a main roller are regulated and controlled, and heating, cooling and other systems are supple
