The muffle furnace is maintained with attentive matters

The muffle furnace is maintained with attentive matters:
1.When the muffle furnace uses again after using or for a long time inactive for the first time, must carry on the baker. The time of the baker should be four hours for 200 ¡æ of room temperature. 200 ¡æ to 600 ¡æ is four hours. While using, furnace temperature can’t exceed the specified temperature at most, so as not to burn the electric component. It is forbidden to pour into various liquidly in the stove and metal apt to dissolve, the muffle furnace had better work at under 50 ¡æ of below maximum temperature, the stove silk has longer life-span at this moment.
2.Muffle furnace and controller must not exceed 85%, work in the relative humidity as the place of conductive dust, explosive gas or corrosivity gas. When all metal materials with oil,etc. need to heat, a large amount of volatile gas will influence and corrode the surface of the electric component, enable its destroy by melting or burning and shortening life-span. So, should prevent and do the sealed container well in time or open the hole to get rid of appropriately while heating.
3.The muffle furnace controller should be limited to using within the range of 0-40 ¡æ ambient temperature.
4.According to the technical requirement, often check fixedly whether the line of every wiring of electric stove, controller is good, instruct the appearance indicator whether to block and delayed in the phenomenon at the time of sports or not, and the one that check the instrument because of the magnetic steel, demagnetize, rise silks, shell fragment with the potentiometer is tired and equilibrating and destroying etc. the error caused to increase the situation.
5.The electric thermocouple mustn’t be pulled out suddenly when high-temperature, in case the overcoat is bombed and split.
6.Often keep the burner hearth clean, remove things such as oxide,etc. in the stove in time.
The muffle furnace uses attention: Can’t go on and toast the flammable, explosive product in the stove, it is dangerous to so as to avoid! Can’t heat the volatile corrosion material either, otherwise will influence its service life.
It is similar that installing, atmosphere stove installation it is had that the muffle furnace is installed to tube stove installing, reaction electric stove installation, drying cabinet. The above has introduced the muffle furnace and installed step and wiring procedure specifically.
