COSS (CONTINIUOUS OPTIMIZED SHAFT SYSTEM) technology for scrap preheating was developed by FUCHS TECHNOLOGY AG. It combines the advantages of flat bath operation (improved power input at the beginning of the heat, low noise, smaller transformer power, less refractory lining consumption and short power off times), as well as the higher scrap preheating efficiency of the shaft furnace.
Key Benefits:
- Reduced electrical energy consumption by scrap preheating
- Reduced electrode consumption of approx. 10%
- Decreased Tap-to-Tap-Time leads to higher productivity
- Charging causes no power-off time
- Reduction of dust amount
- Improved temperature control of off-gas-temperature
- Less dust on EAF working platform – better working conditions
- Controlled scrap quantity input through weighing system installed between wheels and COSS frame
- Controlled preheating temperature through off gas regulation system
- Controlled scrap input through regulation of pusher speed
- Flat Bath Operation (improved power input at the beginning of the heat, low noise, smaller transformer power, less refractory lining consumption)
