China's heat treatment industry energy saving and consumption reduction, saving electricity, gas and other energy consumption are the key development goals of China's industrial belt furnace and gas furnace manufacturing. Some enterprises in China do not pay attention to energy consumption, and the heat treatment furnace equipment is backward. Even some heat treatment enterprises are still using the old-fashioned well furnace, box furnace and trolley furnace in the 1950s-60s, which have poor sealing performance Large heat storage capacity, long heating time, serious heat dissipation, become the power consumption of heat treatment.
The door of the industrial electric furnace is the most frequently opened and closed part. If the gap between the door and the furnace body is large and the sealing is not good, a large amount of accumulated heat in the furnace will be sent out from here, thus wasting power. The high sealing furnace door can greatly reduce energy consumption.
One is that the upper and lower rollers are pressed tightly to make the upper and lower parts of the furnace door close to the furnace surface, and the air tightness is relatively high. The other is that the four connecting rod can compress the sealing groove elastically to make the furnace door double sealed. With this kind of furnace door, the temperature at the furnace door is relatively close to the temperature in the furnace uniform temperature zone.
The opening at the connection of the lead-in rod of the heating element of the industrial electric furnace is also a part of the furnace body loss temperature. The special refractory fiber plug is used to plug the gap of the outlet rod hole, which can effectively reduce the leakage temperature of the furnace body, thus improving the sealing performance and reducing the energy consumption.
In addition, if the opening at the connection of the lead-out rod is not sealed, the temperature uniformity of the industrial electric furnace will also be greatly affected, thus reducing the quality of the heat treatment process. The experimental results show that, according to the size of the furnace, the temperature difference in the furnace with unsealed lead out rod can be as high as 10-30 ℃.
