How much does the temperature of the high-temperature electric furnace drop to open the furnace door?

First of all, considering the life of the heating element and the furnace chamber and avoiding the rapid heat and cold of the furnace chamber, it is recommended not to open the furnace door when the temperature is too high.

In addition, the heating rate of the high-temperature electric furnace is limited. It is recommended to be lower than the rated value. If it is too large, it will cause the program temperature to rise rapidly, thereby increasing the difference with the actual temperature. At this time, the electric furnace will automatically increase the heating current. Will cause the current to rush too high. It will cause damage to the program setting module and cause the electric furnace to lose control of the heating program. For cooling, if the heating resistance wire is not exposed to the outside, it is no problem to open the furnace below 200 degrees; if the resistance wire is exposed in the heating chamber, it is recommended to wait until it is below 100 degrees or even room temperature, or it will not cause damage to the furnace, heating resistance The wire will cause damage due to the excessive temperature difference.
