(1) The temperature rise of a high-temperature furnace must be gradually performed by gradually increasing the voltage. Be careful not to exceed the safe temperature so as not to burn the heater stick.
(2) When using the electric furnace, do not subject it to severe vibration, because the red heating rod is easily brittle.
(3) Don't let the high-temperature oven get wet to prevent leakage.
(4) When placing the material into the furnace, do not touch the thermocouple, because the hot junction of the thermocouple projected into the furnace is easily broken at high temperatures.
(5) It is not advisable to put acid or alkaline chemicals or strong oxidants in the hearth, and it is also forbidden to burn explosive dangerous articles in the hearth.
(6) When placing metals and other minerals in a high-temperature furnace for heating, they must be placed in a porcelain eddy or porcelain dish that is resistant to high temperatures, or padted with fire-resistant clay or asbestos plates to prevent sticking together with the furnace.
