AI Technical Summary
In existing heat treatment furnaces, the heating tubes are fixedly distributed on the inner wall, resulting in uneven heating of the magnetic core in various directions, which affects the heat treatment effect.
By setting a toothed ring and gear structure inside the heat treatment furnace, the heating tube can reciprocate along the inner wall, ensuring that the magnetic core is heated evenly in all directions. The use of vent holes and transmission belts to distribute the load improves the uniformity of heat treatment.
This achieves uniform heating of the magnetic core, improves the heat treatment effect, and avoids the impact of hot air leakage on heating efficiency.
