Problems solved by technology
[0003] Castings such as wear-resistant steel ball steel sections need to be heated in a resistance furnace during processing. They are widely used because of their fast heating, large volume and simple structure. However, since the resistance wires in the resistance furnace are all installed on the furnace wall, Therefore, the temperature near the furnace wall is higher than that of the furnace core. In order to keep the temperature of the castings in the furnace constant, the resistance furnace needs to be turned over so that the castings at the furnace core are closer to the furnace wall, but when the castings are turned over, the castings will slide, so It often hits the refractory bricks in the furnace. Some castings are of high quality. Under the greater impact force, it is easy to smash the refractory bricks. Therefore, the refractory bricks need to be replaced frequently, which not only affects the service life of the resistance furnace, and increase the workload of workers

Embodiment Construction
[0008] see figure 1 , the specific embodiment adopts the following technical scheme: it forms a closed space by the base 1 and the furnace body 2 above the base 1, and a trolley 3 is installed on the base 1, and the trolley 3 can slide back and forth on the base 1, while The trolley 3 can also be turned over. A layer of refractory bricks 4 is laid on the trolley 3. A steel plate 5 is inserted in each brick joint of the refractory bricks 4 on the four sides of the trolley 3. The height of the steel plate 5 is slightly higher than that of the refractory bricks 4. When the trolley flips the casting, the casting will roll to one side, and the casting will first hit the steel plate inserted in the brick joint, and then hit the refractory brick, because most of the impact force is absorbed The steel plate is buffered, so the impact force on the refractory brick is very small, so the refractory brick is not easy to damage, which reduces the frequency of replacing the refractory brick...

A bogie hearth turnover electric furnace relates to the technical field of wearable steel ball manufacturing. The bogie hearth turnover electric furnace comprises a base, a furnace body and a bogie frame, wherein the furnace body is mounted on the base, the base is provided with the bogie frame, a layer of fire brakes are laid on the bogie frame, steel plates are inserted inside the gaps among the fire brakes on the circumference of the bogie frame, and the height of the steel plates are higher than that of the fire brakes. The bogie hearth turnover electric furnace buffers the impact of castings on the fire brakes, largely prolongs the service life of the fire brakes, improves the usage efficiency of the electric furnace and reduces the workload of workers.
