Reasons to open the furnace door when the muffle furnace is hot

In order to quickly cool the ceramic fiber muffle furnace, the furnace door is opened when the temperature is high.

Koska ceramic fiber muffle furnace has a very good insulation effect, the energy consumption during insulation is very low, and the temperature drop rate is also very slow after stopping the work. Some customers hope that the next experiment can be carried out immediately after the completion of one experiment, so the furnace door is opened at high temperature to quickly reduce the temperature in the furnace, but this will cause great damage to the muffle furnace hearth. It is easy to cause the hearth to crack when it is cold and hot. At the same time, the heating element cannot withstand such cold and heat shocks, which reduces the service life. Generally, it is recommended to open the furnace door carefully when the temperature of the ceramic fiber muffle furnace drops below 300°C. If you really need high-temperature pick-and-place parts, you should consider using a custom-made furnace with special materials.
