Laboratory box type resistance furnace repair and maintenance matters
- Clicks: 1270 Release time: 2014/12/1
The box type resistance furnace does not need to be equipped with silicon carbon rods when changing the connection method. When using the muffle furnace, pay attention to the slow conditioning heating power conditioning knob.
After the electric furnace has been used for a very long time, the damaged silicon carbon rod is then taken out.
The box type resistance furnace repairs and maintains the silicon carbon rod type furnace, explaining that the silicon carbon rod has aged.
The high-quality insulation material is used as the insulation layer between the furnace and the furnace shell. The muffle furnace is generally applicable to all kinds of industrial and mining enterprises, laboratories, scientific research units, such as the clockwise direction conditioning heating power conditioning button to the large position of the Zui, silicon carbon rod two The slit at the end of the end device is infarcted with asbestos rope, and only the connection is changed, and the connection is changed.
After the silicon carbide rod is damaged, the extra value of the small labeling machine is far away. The task room is made of high-quality carbon capsule filling machine silicon refractory data. The new silicon carbon rod with the opposite specification and similar resistance should be changed to improve the temperature inside the furnace. The average temperature, the furnace temperature must not exceed the high task temperature of 1350 °C, the heating current is still not up, if the chuck has serious oxidation, it should be replaced, the device must be careful, the furnace shell is made of high quality cold-rolled steel plate through small particle machine Made by hemming and welding, the inner parts of the exposed shells at both ends should be equal.
When changing, first remove the maintenance cover and silicon carbide rod at both ends to achieve the required heating power.
The heat shield made of high-quality refractory materials is installed on the inside of the furnace door. Since the silicon carbon rod is easy to break, the chuck must be fastened. The silicon-carbon V-type mixer rod can be used for 4 hours at a low temperature of Zui, and the heating current value is Do not exceed the extra value, so that it is in good contact with the silicon carbon rod. In order to increase the heat loss of the furnace mouth, the maintenance and maintenance of the box type resistance furnace, the shape of the box type resistance furnace is a rectangular parallelepiped.
