15 11月 Launder Pre-Heaters
Launders and heated launder covers provide considerable energy savings and are safe to work around. The Adtech Materials’ heated cover system provides the cast house with a means to accurately pre-heat the launder system to virtually “steady state” condition.
The refractory is preheated to the target metal temperature to assure optimum starting conditions and negligible temperature drop from the furnace to the casting center.
Covered launders provide significant energy savings and are safer to work around. Rex Materials’ covers are hinged for easy access. They use a Adtech? ceramic fiber element module retained in a steel shell. Pyrolite is extremely buoyant in molten aluminum.
All cover assemblies are provided with a 2000?F (1090?C) woven ceramic gasket where they rest on the top of the launder. This is to minimize both heat loss and potential cover gas outflow.
Materials supplies a trough heater system that is incorporated into the launder covers. The covers are designed to heat the surface of the refractory to the target metal temperature of 700C to ensure optimum starting conditions. Rex Materials’ heaters will, when supplied with the required power input, preheat the refractory to the target temperature within 1 hour.
