Furnace maintenance for aluminum in high pressure die casting foundry. The furnace undergoes on a heating vault’s maintenance. Once the maintenance is completed, it takes 4 hours to heat up to the casting temperature (675°C)
Furnace’s info:
- Furnace capacity: 1500kg
- Casting temperature: 675°C
- Furnace’s type: Heating Rods
Lethiguel’s solution
A temperature maintaining solution, WattMobil with a Thermal Power heater of 14kW
The heater was started at 9.40am from 636°C
Results:
Red line: With WattMobil, started at 9.40am
Blue line: Without WattMobil
Green line: With WattMobil, started from the beginning
It took 1 hour 20 minutes to reach casting temperature and restart production.
Compared to existing solution, the WattMobil reduced the maintenance time down to 2 hours and 40 mins instead of 7 hours!
Suggestions:
By using the temperature maintaining solution during the maintenance, we could reduce the temperature drop and restart the production sooner
