“Molla srl” Installs 4th Roller Hearth Line
According to Austrian furnace builder “Aichelin” forging company “Molla srl” of Italy has just installed and commissioned their 4th automated roller hearth line;
“Together with our long-standing sales partner Efisio Carutti (Carutti S.r.l.), we have successfully installed and commissioned the fourth fully automated roller hearth furnace at a major Italian forging company. The system achieves a capacity of 4,000 kg/h and is used for the isothermal annealing of forged parts under a protective gas atmosphere. With state-of-the-art equipment and control technology, this project sets new benchmarks in efficiency, process reliability, and documentation.
Technical highlights for maximum efficiency and minimal media consumption:
The system stands out with a range of innovative components:
- PLC and FOCOS 4.0 – the digital, intelligent process control system
- High-performance rapid cooling chamber with integrated ratio pyrometer
- Vacuum lock to reduce media consumption
- Modern, energy-efficient heating technology
- Insulation in line with the latest state of the art”
“Digital process reliability with PLC and FOCOS 4.0
The seamless interaction between the customer’s warehouse system, the PLC, and the intelligent process control system FOCOS 4.0 enables fully automated and intelligent heat treatment – including complete and traceable heat treatment documentation.
Via PROFINET, order data, part numbers, and recipe numbers (reference values) are transmitted directly from the customer’s warehouse system to the PLC. At the same time, the target heat treatment parameters for the three process stages are defined in FOCOS 4.0:
Via PROFINET, order data, part numbers, and recipe numbers (reference values) are transmitted directly from the customer’s warehouse system to the PLC. At the same time, the target heat treatment parameters for the three process stages are defined in FOCOS 4.0:
- HTO (High Temperature Furnace)
- RCC (Rapid Cooling Chamber)
- LTO (Low Temperature Furnace)
The edited recipes are then transmitted to the PLC, after which the system automatically adjusts to the respective order. Throughout the entire heat treatment process, all process data and actual values are continuously transmitted to FOCOS 4.0 in real time.
THE RESULT is complete, transparent, and fully traceable heat treatment documentation – a key factor for quality assurance and process documentation.”
