Energy Savings Using KALTEK^TM Ladle Linings

This US-based steel foundry customer was looking to improve its operations by reducing arc furnace tapping temperatures and the rate of heat loss in pouring ladles.

Foseco offered a customized solution using the KALTEK insulating ladle lining systems which resulted in an annual net cost benefit to the foundry well in excess of US$ 100,000. 

Overall benefits achieved: arc furnace tap temperatures reduced by up to 60°C with a corresponding electrical consumption saving of more than 500,000 kWh: ladle holding time on the pouring deck was extended by 20%, improving flexibility in foundry operations, and more than 7,500 hours of ladle refractory heating by natural gas burners were saved.  A reduction in CO₂ emissions of 1,174 tons was also achieved.
