The atmosphere furnace is suitable for sintering materials such as silicon nitride in high pressure nitrogen atmosphere. What should we pay attention to in the installation process in order to ensure better use and play a greater role at the same time?
Installation of atmosphere furnace:
1. According to the delivery list, check whether the electric furnace and accessories are complete and whether they are damaged during transportation.
2. Place the equipment directly on the concrete ground without specific foundation.
3. The main power line, control cabinet and compensation line of electric furnace are installed in specific cable trench.
Check whether there is a short circuit between the heating element and the ground.
5. Check whether the internal circuit of control cabinet and instrument is loose.
6. Fastening bolt connecting push rod and furnace body.
7. Connect the intake pipe and the long firing ignition wire.
Measuring temperature of atmosphere furnace:
The furnace temperature is usually measured on the temperature controller after being measured by thermocouple.
The furnace ring can also be used to measure temperature. In the process of measurement, put the temperature measuring ring on the inner cover of corundum crucible and put it into the furnace, and then raise the temperature. After reaching the set value, keep the furnace for 1 hour and then cool down. After the furnace is cooled, open the cover and take out the temperature measuring ring.
Measure the temperature of the ring several times with a micrometer. Then write it down. The temperature measurement of temperature measuring ring is relatively accurate, and the temperature calibration of muffle furnace is also used to measure the temperature field of muffle furnace.
The above is about the furnace atmosphere to help you.
