The invention provides a rotary heat storage type heating furnace which comprises a furnace body, a combustion chamber, a heat storage chamber, communication channels, a sliding rail, an electric sliding table and a heat storage body. The combustion chamber is coaxially arranged in the furnace body. The annular heat storage chamber is arranged outside the combustion chamber in the circumferential direction. The communication channels formed by isolating partition walls are arranged between the combustion chamber and the heat storage chamber. The round sliding rail is arranged at the bottom end inside the heat storage chamber. The sliding rail and the interior of the furnace body are arranged coaxially. The electric sliding table is arranged on the sliding rail. The heat storage body is fixedly arranged on the electric sliding table. The rotary heat storage type heating furnace has the beneficial effects that the heat storage body rotates in the heat storage chamber, the heat in the heat storage chamber can be sufficiently utilized, the uniformity of temperature distribution is improved, and the quality of forged workpieces is improved.
