What should I pay attention to when using high temperature resistance furnace?

1. The temperature rise of the high-temperature motstandsovn must be carried out slowly by gradually increasing the voltage. Be careful not to exceed the safe temperature, so as not to burn the heating wire.

1. When using the high-temperature motstandsovn, do not subject it to violent vibration, because the red hot furnace wire is easily broken.

3. Don’t let the high-temperature furnace get damp to prevent electric leakage.

4. When putting materials into the furnace, do not touch the thermocouple, because the hot end of the thermocouple extending into the furnace is easy to break under high temperature.

5. It is not advisable to put acid- or alkaline-rich chemicals or violent oxidants in the furnace of the high-temperature resistance furnace, and it is not allowed to burn items with the risk of blasting in the furnace.

6. When placing metals and other minerals in a high-temperature resistance furnace for heating, it is necessary to place them in a high-temperature resistant porcelain vortex or porcelain dish, or pad them with refractory clay or asbestos plates to avoid sticking to the furnace.
