A high-temperature heating furnace for a small punch creep test comprises a heating furnace body. A handle is arranged on the outer side of the heating furnace body, the high-temperature heating furnace further comprises a thermoelectric couple and a temperature control device, and the thermoelectric couple is connected with the temperature control device and the heating furnace body. The heating furnace body is divided into an upper heat preservation section, a middle heat preservation section and a lower heat preservation section in sequence from top to bottom. A force application component preformed hole used for installing a force application component and a thermoelectric couple preformed hole used for installing a temperature control component are formed in the top of the upper heat preservation section. A hollow hearth is formed in the middle of the middle heat preservation section, and a plurality of electric heater strips are annularly arranged in the middle heat preservation section and close to the edge of the hearth. By means of the high-temperature heating furnace, the problems that a furnace body of an existing creep test device is large in size, difficult to install and debug, slow in heating and cooling, and high in cost are solved, efficiency of the small punch creep test can be improved, device and manpower cost for the small punch creep test is reduced.
