Storvik has through years of experience and expertise developed a proprietary iron quality structure called PjN-G. This special structure of grey cast iron ensures a quality of iron that prolongs the furnace tending tools lifetime by proven 8 to 10 times compared to our competitors, in turn making the aluminium production more sustainable. Knowing that on average, 1.9 tonnes of CO2 is emitted for every tonne of iron produced (bellona.org), the improved lifetime on the Storvik furnace tending tools vastly decreases the aluminium productions carbon footprint.
The increased life of the tools and the fact that they maintain their special shape during their lifespan, enables standard best practices of the furnace tending and thereby reduces preparation time of the furnace, reduces mobile traffic on the furnace area (which is categorized as the most dangerous area in the aluminium industry) and greatly reduces furnace opening time, thereby reducing emission and direct heat loss.
And possibly the greatest environmental aspect is the reduced dross formation resulting from the optimized designs of the tools. Dross needs to be treated and handled as hazardous waste and dross recycling is expensive and still largely quite pollutive.
In addition to this, the prolonged lifetime of the tools and reduction of dross formation we simultaneously improve the HES for the operator, decreasing the need for manual labour handling the tools and the replacement of them.
