The high-temperature resistance heating furnace is mounted on the bottom of the carrier plate and is provided with moving wheels to facilitate the movement of the heating furnace. In order to make the heating furnace convenient to use in daily life, a moving box is arranged above the base. The placement table is pulled out of the heating furnace through the moving box, which makes it more convenient to place the heated objects. The heated objects are fixed by the fixing plate to increase the firmness of the objects. The placement plate is driven to rotate by the motor to make the objects on the surface of the placement table heated more evenly and the heating efficiency is higher. An observation window is arranged on the surface of the furnace door to conveniently observe the status of the heated objects. Sealing pads are arranged around the furnace door to ensure the overall sealing of the heating furnace and avoid heat leakage to reduce the heating efficiency.
