Improved monolithic materials for lining aluminium holding and melting furnaces - roof, upper walls and flue

摘要

As aluminium producers strive to increase productivity, the environment within furnaces for holding and melting aluminium is becoming more aggressive. Chamber temperatures are increasing and more aggressive fluxes are being used, necessitating more frequent and severe cleaning operations of the refractory wall. A key requirement for maintaining high levels of productivity is the need to minimise the frequency and duration of furnace downtime.
