In the silicon carbon rod type furnace, after the silicon carbon rod is damaged, the new silicon carbon rod with the opposite specification and similar resistance value should be changed. When changing, first remove the maintenance cover and silicon carbide rod at both ends, and then take out the damaged silicon carbon rod. Since the silicon carbon rod is easy to break, the device should be careful, the inner part of the exposed shell should be equal, and the chuck must be Fasten to make good contact with the silicon carbon rod.
If the chuck is severely oxidized, it should be replaced. The slits at the holes in the device at both ends of the silicon carbon rod are infarcted with asbestos. The furnace temperature must not exceed the maximum mission temperature of 1350 °C. The silicon carbon V mixer rod allows for four hours of continuous operation at the lowest temperature. After the electric furnace has been used for a long time, if the heating power conditioning knob is adjusted in the clockwise direction to the maximum position, the heating current is still not going up. The small size labeling machine has a far extra value and does not reach the required heating power, explaining that the silicon carbon rod has aged.
The box type resistance furnace does not need to be assembled with silicon carbon rods when changing the connection method. It only needs to change the connection method, and after changing the connection method, pay attention to the slow conditioning heating power conditioning button when using the muffle furnace, and the heating current value must not exceed the extra value.
The box type resistance furnace should be placed in a small, ventilated, non-corrosive gas mixer. The ambient temperature is 10-50 °C and the absolute temperature is not more than 85%.
To ensure accurate measurement, the DC potentiometer is used to calibrate the temperature meter of the xmt type temperature controller every year to prevent large errors. During the current inspection of the box type resistance furnace, whether the local hot lines are loose, whether the contacts of the AC contactor are good, and the defects should be repaired in time.
Box type resistance furnace anti-static clean clothing level maintenance of the infiltration agent medium input maintenance content and requirements are as follows:
1. The infiltration medium input line is unblocked and does not leak.
2. Clean the drip chamber and read clearly.
3. Check that the exhaust pipe is intact and not blocked.
4. Check the joints and valves of each pipe and tighten.
5. Check the exhaust and keep it safe.
Doublet Achromatic Cylindrical Lens
Achromatic Cylindrical Lens is a kind of doublet lens which is cemented by positive low refractive index (Crown) and negative high refractive index (Flint). These two materials are specifically designed to be used together to reduce spherical aberration and chromatic aberration. The extra design freedom provided by the dual design also further optimizes performance.
