Working conditions and parameters of tunnel kiln:
Tunnel kiln length:160 meters
Number of crucibles per kiln car: 6x4x4=96
Working conditions: It takes 24 hours to hear up from room temperature to 1150℃ Celsius insulation time: 1150℃X72 hrs. It takes 24 hrs. To cool down from 1150℃ to 400℃ The above 120hrs.
Are considered as cycle,which means that it takes 120 hrs. For the kiln car to enter and exit the kiln, and it is called one use approximately 60 times a year, the crucible is planning to be used 300 times
