KALMINEX 2000 insert sleeves are extensively used in the Iron & Steel foundry industry. The balanded exothermic / insulating formulation enables a reduction of feeder iron volume of up to 80% compared with an equivalent sand riser. The example shown case gives a saving potential of 31.54 kg iron returns per casting. This is equivalent to a reduction of 18.92 kWh melting power per casting.
In summary the Iron returns and energy savings based on 80,000 casting per year are:
