Zusammenfassung: | The utility model discloses an oven applied to an asphalt fusion experiment, relates to the oven, and solves the problems of influence of the heating effect of the oven and shortening of the service life of the oven as fused asphalt easily sticks to and corrodes heating resistance wires through small heat radiating holes on a bottom plate when the conventional oven is used for making the asphalt fusion experiment. The oven comprises a box body and the bottom plate, wherein the bottom plate is mounted in the box body; the heating resistance wires are arranged beneath the bottom plate; the multiple heat radiating holes and multiple anti-overflowing walls are arranged on the bottom plate; the heating radiating holes correspond to the anti-overflowing walls in number; the anti-overflowing walls adopt cylindrical walls without end surfaces; the inner diameters of the anti-overflowing walls are the same as the diameters of the heat radiating holes; the anti-overflowing walls are correspondingly arranged on the heat |
