1. When the vacuum tube furnace for the first time or long-term use again after the closure, the oven must be carried out. Ovens time should be at room temperature 200 ℃ four hours. 200 ℃ to 600 ℃ four hours. When in use, the oven temperature should not exceed the maximum rated temperature, to avoid burning heating element. Prohibit the furnace perfusion liquid and easily dissolved in a variety of metals, preferably Burnout furnace is below the maximum working temperature is 50 ℃, then furnace wire has a longer life.
2. The vacuum tube furnace and the controller must not exceed 85 in relative humidity, no workplace conductive dust, explosive gas or corrosive gases. Where fats like with metallic materials to be heated, a large number of volatile and corrosive gases will affect the surface of the heating element, so that destruction and shortened life expectancy. Therefore, when heating the timely prevention and good openings sealed containers or appropriate to be eliminated.
3. vacuum furnace controller should be limited to use in an ambient temperature range of 0-40 ℃.
4. According to the technical requirements, always check the furnace regularly, each wired controller wiring is good, whether the phenomenon stuck stranded indicator pointer movement and electricity meter calibration potentiometer because magnets, demagnetization, rose silk, shrapnel errors caused by fatigue, increased destruction balance situation.
5. Do not suddenly pull out the thermocouple at high temperatures to prevent jacket burst.
6. keep the furnace clean, timely removal of things like the furnace oxide.
