Air-cooled in-furnace camera systems for optimised process control
Engineered to sit in the furnace wall and look straight into 1,100 °C, our cameras give operators a continuous, clear live picture of the melting process, day after day, for years.
Built for the cast house, not the lab
Over a decade ago we installed our first camera in an aluminium remelting furnace. It still delivers an uninterrupted live view today. Everything we learned since is in the current system.
Air-cooled
Compressed air keeps optics and electronics cool, so no cooling water is needed next to molten metal.
Pneumatic retraction
The camera retracts from the port automatically when air pressure drops or when it is not needed, protecting the optics.
Optical zoom
Zoom in on the scrap pile or inspect refractory wear during operation without interrupting production.
Time-lapse and recording
Hours of melting become seconds of video. A visual record for optimisation, incident analysis and training.
Several furnaces on one screen
Show the cameras of several furnaces on one screen in the control room, the scrap bay or on the wheel loader.
Connected
Video to any screen in the plant, results to charging machines and process control systems.
Choose your furnace
Reverberatory melting furnace
Scrap pile, burner flame, dross, circulation, metal level and refractory.
Multi-chamber furnace
Ramp, shaft and the flow between chambers.
Tilt rotary furnace
Rotating scrap, flame and metal level with the door closed.
Decoater technology
Material flow and coating removal live in the kiln.
The hardware
Stainless steel housing, air supply, retraction unit and a control cabinet with the video and analysis computer. Photos from customer installations.
What changes when the door stays closed
Enhanced safety
Operators monitor furnace conditions remotely and stay away from heat, splashes and floor traffic.
Energy savings
An open door loses radiant heat within seconds and needs three times that energy to recover. Closed doors mean shorter melts and lower CO₂.
Improved melt rates
Skim or add material at the right moment and reduce cycle times without opening the furnace.
Proactive maintenance
Track refractory wear over time and adjust burners before problems appear.
Incident analysis
Review recorded footage to analyse and resolve incidents and put preventive measures in place.
Intelligent operations
Prompts for charging or skimming today; automated flame and refractory monitoring in development.
