Moreover, there is a poor sealing performance, which easily leads to heat loss inside the annealing furnace, affecting the heating efficiency and the annealing effect of the workpieces. Therefore, a sealing and heat preservation structure of a vacuum annealing furnace is proposed.

At the same time, it can effectively ensure the sealing effect during the use of the equipment, avoid the situation of heat loss during the operation of the equipment, and effectively improve the practicability of the equipment.

[0005] Although the above patent achieves simple operation and convenient use, it can effectively solve the situation that the steps of opening and closing the furnace door of the traditional annealing furnace are cumbersome, effectively improve the use effect of the equipment and the opening and closing speed of the furnace door, and further effectively improve the processing efficiency of the equipment.
